I never imagined copper wire thefts would become so common or air conditioning units would be stolen for copper. I did a back of the napkin estimate of profits based on various news reports.
First of all, I am guessing based on news reports that on average someone would pull in about $200 for the copper they steal. There is a mileage deduction (unless they steal the gas and car also). Let’s just assume 10 miles to pick up a partner, 10 miles to drive to theft site and canvas, 10 miles to sell copper, and 10 miles back home. I assume the average crook is driving a pickup with an average of 15 mpg. This comes to $12 worth of gas.
The copper prices paid are probably about 50% of market rate at best — so the $200 worth of copper equates to $100 of cost.
The meals to sustain the energy to steal the copper are a back end cost–let’s say two big macs assuming the crooks eat at McDonald’s. That set’s them back $10 more.
There is wear and tear on the car which should also be factored in as 0.33 x miles which equals another $15.
I assume 4 hours total of drive time for casing out the place, removal, and transaction times.
Doing all the math, the crooks made about $7.50 per hour for the theft and this line of work has no benefits such as health insurance and retirement. Therefore, the crooks would do better economically working at McDonald’s which is always hiring.
So why do people steal copper from air conditioning systems and electrical systems? I can only conclude they are from my point of view not bright.
From the perspective of the home or business, the copper theft would typically leave 2 to 5 thousand dollars worth of damage.
For the AC repair business, it means work but not the type we like to do. There is one company that developed a specialized security system for AC systems. These security systems for AC units may be a growing industry in Las Vegas–Yahoo News.
In any case, the AC season is here. And it will be interesting if there is any uptick in theft-related AC repairs. I need to learn a little bit about new security systems to lock down AC units. I saw there is a new section on security Air Conditioning parts.
Times have changed for the las vegas ac repair business: Economy tough but the AC repairman is still keeping homes cool
April 22, 2012
Las vegas being unbearably hot for many during the day leads to a good business for the summer–repair of air conditioning systems. This business is somewhat cyclical with unlimited demand on peak hot days and virtually no work on other days. While the air conditioning business could rely on the weather as a predictor of work–those days may be over.
The financial crisis and subsequent high number of foreclosed homes in las vegas has destroyed any ability to predict work. The market forces are being skewed by banks and government policy to maximize the money banks will receive. Everybody knows that the banks are essentially underwater at today’s home prices and so they cannot afford to sell foreclosed homes. This leaves many paying really high rents and many unwilling to invest. As always the rich speculators and not ordinary people looking for a place to live will benefit from the misery.
In the wake of the home building collapse, the biggest company in las vegas air conditioning–Interstate–went into bankruptcy. This left the market wide open, but the problem is no one knows what the market is anymore. Government policies heavily influence whether people will buy or upgrade air conditioning through direct energy efficiency subsidies and indirectly by affecting the health of the market.
Many of the smaller air conditioning companies are on the verge of bankruptcy or will be filling for bankruptcy.
I for one look forward to retirement this summer and hope it will be a good year. But all the signs are that the work will be sporadic and light. There are hopeful signs too.
I see two two new companies rising from the ashes. Las Vegas Air Conditioning Repair is looking to help the homeowner with affordable air conditioning repair services. They only started late last year and were cobbled together by people laid off from AC companies that could not survive.
Another newer air conditioning company-Air Conditioning Las Vegas– is gambling on small business needs. They focus on the air conditioning needs of small and mid-size businesses. They also were cobbled together from down-sized air conditioning companies.
But on the whole, there are fewer air conditioning companies and the ones that exist are smaller. The flip side of all this negativity is that the remaining air conditioning companies probably provide higher quality services and a faster turn around. Although there is little any small air conditioning company can do about the rising cost of equipment, parts, and gasoline.
Sustainable design for homes and businesses has become the right thing to do. Twenty years ago, I don’t recall anyone getting graduate degrees in sustainable design. In the 1980’s it was still common to throw aluminum in the garbage and rebates for energy efficiency upgrades were non-existent. Now there are tax incentives and rebates for installing wind and solar energy generators. One of the most common side businesses for HVAC repairmen is to simply plug air leaks and provide better insulation on ducting—energy upgrades reduces electricity bills for the homeowner, reduces toxic pollutants to our atmosphere, and lets us as a society more efficiently use resources for other essential needs.
I am amazed by the constant improvements in every aspect air conditioning design, construction, and installation.
Compressors have become efficient and quieter. These new compressors are often used on heat pumps and are advertised as scroll compressors. I attached a link on youtube for how a scroll compressor works. I think they are mind-boggling in design.
Heat exchangers leverage the environment for greater efficiency. In the old days, AC systems would try to put heat into a hot environment and the heat exchangers were often in direct sunlight. I’ve seen systems that pump heat to groundwater or the subsurface for cooling homes, or vice versa for heating homes. I’ve seen systems that pump excess heat from homes into a swimming pool. All of this just seems to make sense.
I suppose all this makes sense now because of the environmental/green movement. I thought about this and think we have Al Gore, the USEPA, and China for all this. Most people can figure out Al Gore (climate change noble prize winner) and the USEPA (mission). But China?
China because of their incredible growth has taken us very close to the edge of resource limited output. In 2010, we demand for energy (for example oil) approached theoretical production capacity. Basic materials such as fertilizers, concrete, iron, and copper have all grown faster than supply and we may not be able to produce enough with our current lifestyle expectations.
Somehow as a society we have begun mindset change in lifestyle. Green is chic and sustainable growth may avert possible wars over oil and minerals.
This environmental movement has impacted everyone’s world. For my world, I need to learn about insulation, energy rebates, city and federal tax incentives, and sourcing the most energy efficient AC models. But I think our evolution in lifestyle expectations will still undergo much change.
Air conditioning is a necessity in Las Vegas on some days. But there are other times when it is a luxury. Already residents shift their activity to cooler times of the day. Perhaps this is why night life in Vegas is so great. We also learn to turn up the thermostat and let our bodies adjust. We can adjust our activities to include sitting in shady spots. We can use shades to reflect the sun. We could paint all of our roofs white as DOE suggested but this goes back to design and public perception—white reflective roofs for homes are not chic yet—but is a low-hanging fruit for saving energy and the environment. Maybe if Arnold Schwarzenegger gets a white reflective roof, it will become the trendy thing to do.
I’ve been thinking about solar powered air conditioning but believe painting your roof white has better cost/benefit. Solar panel construction and installation have an enormous environmental cost built in—but it’s just hidden. Our rulers (life cycle analysis) are not sophisticated enough to show the consumer the best investment when it comes to being green. Currently, wind power is the only green energy that is truly green by any measure and the cost/benefit to society is good. As an air conditioning guy, I do not recommend solar powered AC systems yet. I know some customers have huge tax incentives and in these cases there are quality solar powered AC systems if you have enough roof space.
There are other aspects to AC that have changed. Freon has become bad as most people know. Freon is reclaimed by EPA certified reclaimers. Manufacturers have gone to use chemicals that are similar to Freon but cause less environment damage. Ultimately, the industry will go back to the original chemical—ammonia. Currently, HCFCs are acceptable but in reality, they cause the same damage as the Freon they replaced. Ammonia is everywhere and used for fertilizer, unfortunately, pure ammonia is dangerous. But if safety engineering improves, ammonia technology may become universal for home air conditioners.
The EPA has created the “GreenChill” program which gets to greener forms of air conditioning. This webpage is replete with event and webinars for green air conditioning. You should check it out—being from Nevada, I don’t often recommend EPA for anything but I think they are doing something right here.

Life always has its ups and downs. For the plumber its the hot chick saying hello on the strip followed by finding out she says hello for money. It is Las Vegas after all. For the environmentalist its about seeing all the new studies about PCBs in caulk (all that caulk plumbers and AC men used for years to seal cracks and joints to keep your home comfortable) only to find out once again EPA science lags behind its imagination. For the record, PCBs were used in caulk until the late 1970′s but as with dioxins in clay pigeons (if your an environmental scientist you’ll understand this) that toxic chemicals that are not bioavailable or not really toxic.
I was think of other chemicals too we use to paint HVAC equipment to prevent corrosion. There was an interesting article discussing corrosion of metals being significant for HVAC equipment that is difficult to do routine maintenance. Have you ever noticed your outdoor air conditioning equipment with rust stains. In the old days, we used paint with lead to protect our HVAC equipment, a guy at Ideal Service told me; since they are good at keeping their air conditioning equipment in good condition, I believe him. I was talking with another guy at Silverfox who told me about the tin in paint they used on Navy ships. This got into all sorts of exotic metals such as titanium, tantalum, and zirconium to prevent corrosion of heat exchangers for their air conditioning equipment. I think Silverfox has some of the best professionals in the HVAC repair business. The people they have really understand the engineering behind air conditioning for extreme conditions.
So all this brings me back to where I was a couple weeks ago about environmentally friendly refrigerants. All that freon we used for so many years in air conditioning equipment has created a long-term environmental problem. But I have faith that the scientists and engineers out there will continue to make air conditioning more environmentally friendly. I have a lot of thoughts about this and what can be done and some of these ideas are what I tinker with at night.
I also want to write about all the corrosion resistant elements of heat pumps when they are used for heating swimming pools. The summers in Las Vegas are hot enough that heaters are not needed but the engineering improvements with time are interesting.
Speaking of Summer, I know everybody in Las Vegas will soon be calling their friendly neighborhood air conditioning repair person. I don’t like to recommend the competition but I am retiring soon, so I need to send the work to the younger AC repair men and women. I was thinking of ordering some skirts for the repair-women if I can hire one. For some reason, I only have guys and I’m still old-fashioned and cannot imagine using pants as an AC uniform for a lady.

Silver Fox Air Conditioning, Plumbing is good for repair jobs. They like fixing problems. They also have an attractive secretary who speaks with a heavy accent. But even she likes to talk about air conditioning. I think she has a night job nearby and is trying to make AC Repair her new career. They are pretty clean-cut honest group that knows what they are doing. They tend to focus on a few jobs at a time.
Ideal Services has one the prettiest webpages I’ve seen. You can see they have about 20 young lads working there — all well trained and eager to make their way in the air conditioning field. I think this guy tries to help disadvantage youth get a career and I like that about them. I would say they will do you right for air conditioning repairs and the price will be fair. I know they do plumbing too.

My motto is to call me last. I like the most difficult problems and tend to charge less for the opportunity to work on them. I will solve those problems that nobody else can. I will tell you though that if the job is routine I will most likely refer the job to one of my friends. I love giving air conditioning repair estimates and advice. I live in the Las Vegas community and am always happy to make new friends.
Cycles – in Life, in the Economy, and Air Conditioning…Summer 2012 will be great-I have faith Obama has the fix in for the economy timed for the election
February 5, 2012
The world as we know it is full of symmetry. There is symmetry on every distance scale and every time scale. Most of the symmetry is circular. History teaches us that. Countries rise and fall. Everyday life teaches us that too. A husband being nagged about looking at the map will drive in a circle. And whatever happens will happen again. The underlying reasons for this are beyond our control or ability to understand. Philosophers get famous for thinking of plausible explanations for the way things work. But in the end we are faced with the reality that we are simply not meant to understand everything.
So we are given cues in nature. The cycle of the sun rising and setting for when to sleep. The cycle of the seasons for when to do work. The cycle of activities set in motion by the nagging wife.
We have lived in the US through ups and downs in the Economy. And Economists are always able to explain the science of why we had an up or down cycle with 100% accuracy– after the fact– and after they had a chance to change their models or prior statements. Do you know that roughly 50% of economists predicted the last recession and roughly 50% predict any major economic event before it happens? In other words, after studying complex mathematics and social systems and sometimes even getting a Noble Prize for their work, Economist predictions are as accurate as flipping a coin. I hate to say it but the US probably should start flipping coins because its cheaper than hiring consulting economists–some of whom cannot even understand Turbotax– for example, Tim Geitner, Secretary of the US Treasury.
But in any case, we don’t need to flip a coin to understand that summer is coming and that means more work for us in air conditioning in Las Vegas. This will be my last summer of work but I think its going to be a big bang. I have noticed that President Obama has a lot of unspent stimulus money. I have no doubt that Obama is planning on strategically injecting that money into the economy in preparation for the next election. If you looked at the recent unemployment results, we are now at 8.3%. Mark my words, Obama is very close to his objective — less than %7.8 unemployment. Why 7.8? So he can make a claim that things have gotten better. If you recall, unemployment was 7.8% when Obama took office.
I expect this summer to be one the busiest in the last several years because of planned government stimulus. While the money should be spent now, I have no doubt that is politically advantageous to spend money in away that creates the impression of an economy roaring back. It seems unfair that our quality of life is affect by political ambitions and things will get better when it is good for those in power. I don’t see how the economy will improve, but I have absolute confidence that Obama will artificially inflate the economy this summer to win an election. An improved economy means work for air conditioning repair people and work companies making air conditioning equipment. If things go right, I’ll retire this summer with one of the busiest summers ever. All this because of my unwavering belief that Obama has the “fix” in to win the next election. Also because I started my Las Vegas Air Conditioning website — and it seems to be popular. I get more calls than I ever expected–which is none. I wish I had gotten into the internet stuff years ago and mostly did it to find a retirement hobby and be able to converse with nephews and nieces. (I’m even digging into Facebook, but they sure do invade your privacy. I don’t know if Facebook is worse than the greedy banks that have sold your private information for years or if they are just more effective at information gathering. I was surprised to find out that Microsoft is more respectful of my privacy than Facebook.)
But back to cycles–I don’t have faith that Obama is actually fixing the economy for the long term and will somehow reduce the severity of the up and down cycles that cause average Americans hardship. Has Obama accomplished anything since he’s been in office that matters to the average person? I know he’s been taking taking on more of a leadership role in the last few months, but he’s been a Jimmy Carter for the last two years. I think we are for in one hell of a economic fall in 2013. Even if Mitt Romney wins, I never really considered Romney that different from Obama.
Who know’s maybe I’ll have to learn Chinese because we may entering the Age of China again–again because of my belief in cycles in everything. (If I remember correctly, somewhere around 3000 years ago, China was one of the leading countries on earth.) I believe this as much as I believe a wife has 4 week nag and headache cycle.

What do they all have in common? Another true story about air conditioning.
Probably if you think back to sesame street, you’ll remember what do these things have in common. Its a thinking exercise for children. Well lawyers and mold have the most in common, but all three intersected for me in the waiting area of the las vegas airport a few days ago.
Two lawyers were pompously talking the lawyer talk of trying to look smarter than the other on a wide range of topics. Then the housing market and all the foreclosures came up. One of the guys said to the other, he made a bundle because he could get a foreclosure and it was always easy to find mold. He went on to say that it was easy to prove faulty ventilation or air conditioning was the cause of mold in homes. Proudly, he then explained it was easy to sue air conditioning or HVAC contractors for a bundle. As I understood it, the slimy attorney (I know a pleonasm) had figured out a way to profit off the homeowner going into foreclosure, the bank holding the foreclosed loan, and still screw the air conditioning guy who worked on the house before the foreclosure happened. All this in the las vegas airport. The other lawyer was impressed. I think humane humans (a non-tautology as I discovered after thinking lawyers versus human to be reminded that humans are not always humane) would be disgusted. Disclaimer note- I believe the lawyers were both from California. Lawyers in Nevada are more respectable -and I say this proudly- no legal trickery just bribes.
So now I know why I pay so much for insurance to do my job. Has anybody ever looked to see if attorneys cross-bred with blood-sucking mosquitoes sometime after arriving in California during the 1890s.
Would it be green to recycle attorney heads as road bumps or would it be silly because people would drive in circles to go back get the missed bumps–thus causing traffic jams instead of merely slowing traffic down?
All that ranting aside, mold is a serious problem in some homes. Especially in the southeast and houston. It is bad and EPA says-and I agree with EPA in this case- mold can cause a wide range of illnesses. Luckily in the dry las vegas area, dust is more of a problem. I hate to admit when EPA may be partly right about the PM standards and that Herman Cain fellow cited as a reason to get rid of EPA (before his naugty side was reveled)…he said EPA even wants to regulate dust. Well do a google or bing search on mold if you see mold in your house. It is harmful. Hopefully you’ll remember the moral of the story… being a rich and articulate pizza maker does mean you understand science–so ignore Herman Cain when it comes to EPA.
January 29, 2012
I came across several interesting blogs about air conditioning bills yesterday and added my thoughts on city-data.com. I actually never knew much about the site but within about 12 hours I got a pop up message on my screen when I opened the site — life-time ban from the City-Data.com site for “advertising”. I tried to go back and see what I wrote, but the ban prevented me. So it was another lesson learned….I’ll probably stick with the land of the free– wordpress.com
I’ve only been using wordpress for a short time but have had no hassles and everything works. The city-data.com site appears to have roving hitler bots that did not like what i wrote. I am pretty sure that the only link I added was to wordpress.com. No email, no chance to look at what I did, but found guilty — city-data.com sucks. So in the spirit of fee enterprise and free speech and using the same approach of city-data of finding me guilty of something — I find city-data.com guilty (of something) and dub them internet fascists. (of course it could be mistaken identity or a cookie programming glitch but nevertheless I hate being judged without due process)
So let me see if I can remember what I wrote about that got me in trouble. I commented about Obama’s recent trip to Nevada and Mayor Goodman in the spirit of fun and game politics stating someone had to go out and meet the President and the mayor pretty much gets paid to do that. This combined with the fact that Governor of Arizona pulled a confrontation on the airport tarmac with Obama shows the political machinery is out there creating an image revolt against Obama. There is nothing more devious or crafty than a political party trying to win an election except your common breed of attorney–found in every dark corner from Seattle to Miami and San Francisco to New York.
But I do think Obama’s got the green energy thing right (partly). Wind energy is cost effective and we should do it. Solar and ethanol is a rip-off right now. Ethanol has always been a tax payer funded bonus to Archer Daniel Midland and every politician on their payroll. Ethanol has no pluses but it makes make many snake oil salesman rich. Look up the history of ADM with bribes and politics and monopoly abuses if you are too young to remember. ADM is the reason that soda you drink is made from corn and the chicken nugget is 50% corn. Think of ADM of the company that made artificial in McDonald’s food possible and profitable for both–and of course absolutely terrible for the health of kids. But read Wikipedia for the bland facts on ADM.
But back to Obama….he did give the air conditioning repair guy a big boost because of credits to fix air leaks around ducts in homes. It saved homeowners money and kept me working a little more than usual. We will see how the summer of 2012 goes though. I have a feeling with the real estate market still a mess.

January 24, 2012
We have had the driest winter in over 100 years. I should pull up the farmer’s almanac to see how the summer is going to look. The hotter it is, the more people ask for air conditioning help. For some reason, I am slowing down and just don’t have the drive to do field jobs anymore. The air conditioning market has become very competitive. In reality, there is probably work enough for all, but there are some greedy bastards out there. I started noticing fly by night AC shops being advertised recently. Maybe they are working on other peoples licenses. But after so many years in this town, I suspect that we have some that are moonlighting. That’s a big no-no in this town. Vegas likes to control its contractors and makes a lot of money off the licensing procedure….so if you are not paying the license properly, you better be bribing properly.
All seriousness aside, even this lowly air conditioning man gets calls from Obama supporters about voting and donations. I really lost my enthusiasm a long time ago. Basically, the government bailed out the rich people. Rich people made money by taking high risks. But when everything fell apart, the government covered the rich. I bet Geitner and Bernanke are probably the two greatist elitists in the USA and Obama loves them. At least the old theory was trickle down money….but the Obama theory is to print money for the rich.
I have to admit. Obama has become a do-nothing president. He’s bent over to special interests on all sides and in doing so –did nothing. Obama can argue a lot of hypotheticals to suggest he did something….but he really did nothing. I look at Newt and Mitt and don’t really get excited. I’m actually thinking that Sarah Palin should run. What we need is a revolution of the working class. Harry Reid needs to go. Obama needs to go. But no Mitt and no Newt.
I was hoping to retire by now but it looks the politicians are still too busy lining their pockets. Its left to the working people to continue to eek out a living.
I started writing this blog to write about AC stuff….and there is much about it. I missed the big anniversary of the first air conditioner and will write about that bit of important history.
Well folks think wisely about this next election….I really don’t care who you vote for…but let’s vote out all incumbents…..we simply cannot do business as usually no matter how eloquently Mr. Obama says it.
I won’t be repairing AC units anymore as I am winding down my business …..but I will continue to give advice to people. I might be going to the Grand Canyon soon for a visit and will let you know if I get any info from the AC repairmen in Arizona.
P.S. Happy New Year to ALL
December 29, 2011
For some reason, I get the impression that most people think of heating and air conditioning professionals as the plumber with the plumber butt crack showing. I have a lot of respect for plumbers and I would imagine that a working toilet and water line is more important air conditioning for most people on any given day, the reality is that heating and air conditioning is a complex engineering feat. You can go to a university for many years to really understand the complexities. Check out the American Society of Heating, Refrigerating and Air -conditioning Engineers (ASHRAE) if you don’t believe me.
If you want to go further, think about the phase-out of freon due to ozone depletion. A lot of that freon came from air conditioning systems. I hate to think that I contributed to ozone depletion but I didn’t know any better 20 years ago. Most of you kids probably don’t remember or were aware of the big change with the the Montreal Protocol on Substances that Deplete the Ozone Layer. I attached it for two reasons, its redemption for the AC guys and I wanted to find the option to attach a PDF document in wordpress. (Yes, I am a wordpress newbie–I came across and just had to give it a try because everyone talks about blogs–everyone I know that is.)
You know I suspect that the semi-conductor industry which made the computer chips for our modern internet focused society and plastic industry so we can generate lots of garbage for landfills probably contributed much more to ozone depletion than air conditioning did. But that’s the past. Science is active in AC industry developing new replacements for freon. For example, you can see the trade name Puron everywhere. Puron is less destructive than Freon and legal, but its not perfect. Scientists and engineers are probably working somewhere at this very moment to find something more environmentally friendly. I have some thoughts about Puron which I’ll write about next time. Sometimes big companies fib a little. I prefer the Wikipedia description but the slight fairytale version of Puron can be at Carrier’s website about how sustainable and innovative they are. I actually like Carrier products but environmental stuff has become a marketing too and which means exaggeration of truth. In case you don’t know Carrier is one of the big manufacturer’s of air conditioning equipment.
The most environmentally friendly solution is to simply use natural air conditioning or adaption. But this brings us back to the reality of living in Las Vegas in the summer. I probably should talk about heating this time of year, but then I start thinking of fireplaces and burning wood….and the environmental angle about burning wood just kills the warm thoughts of fireplaces. Most people in Las Vegas use natural gas anyway. But whether its heating or air conditioning, adaption is the best way to help the environment. Put on another layer of clothing and turn down the thermostat. Or use the fan during the summer.
But when you need air conditioning and have made peace with yourself about the environmental impacts, you can call me to install that new AC system. Well at least for a few more years. I want to retire someday soon. I need to find a good website that describes changing lifestyles versus use of AC/heating. There are many health benefits aside from the positive impact on the environment. You should read about EPA’s perspective on indoor air quality and energy efficiency. Ooops….I said a bad word for people in Nevada — EPA. But EPA should really beef up their sustainability stuff and take a more holistic and practical approach—and start by getting rid of all those bureaucratic lawyers and start hiring scientists again. One thing I can tell you if you want to go into the AC field is that you will get a big fine from EPA if you improperly use freon. You even need to have special EPA certifications for air conditioning. I am beginning to think half of the lawyers in the US owe their livelihood to the existence of air conditioning and heating. There are even schools for this EPA certification. So some educators are employed because of AC guys/gals too – but that’s a good thing (as opposed to helping feed lawyers).
Here is just a small quote from EPA to give you a flavor of why EPA is a bad word in Nevada. They write too much and you can never quite figure out what you need to do at the end of reading everything because it takes you a long time to read it.
Service Practice Requirements
1. Evacuation Requirements
Technicians are required to evacuate air-conditioning and refrigeration equipment to established vacuum levels when opening the equipment for maintenance, service, repair, or disposal. If the technician’s recovery and/or recycling equipment was manufactured any time before November 15, 1993, the air-conditioning and refrigeration equipment must be evacuated to the levels described in the first column of Table 1. If the technician’s recovery or recycling equipment was manufactured on or after November 15, 1993, the air-conditioning and refrigeration equipment must be evacuated to the levels described in Table 2, and the recovery or recycling equipment must have been certified by an EPA-approved equipment testing organization.
Well good night. I hope someone out there appreciates– a little more– the significance of air conditioning to our way of life.
December 25, 2011
I found a little time on Christmas to write about my passion — air conditioning and heating. I remember watching cartoons about the birth of christ in a barn on hay. Even back then I thought about heating. Perhaps because we lived in a cold area and had an old heater. Our house was always cold in December and I associate cold with those Christmas movies for children.
Of course, during the summer, our house was too hot and we had not air conditioning. I guess the nice way to think about it was we were having a low carbon footprint or being energy efficient. The cynical side of me says the truth though that wealthy people use words like low carbon footprint and make choices. This is a choice that my family did not have.
But now I live in Las Vegas, I cannot really imagine how summers can be bearable on most days without some cooling. There are good choices like sitting in the shade but some days are just too hot. Especially if you have small children who get cranky.
I feel like I am helping people by fixing their AC or heating and they really appreciate it. There are many aspects of heating and cooling that I think are fascinating and they are details people don’t think about. But pretty much everything I learned in school is related to heating and air conditioning. I don’t look like the Maytag man and I am certainly a lot busier than he was. But I would like to share my thoughts about the details that make life in Las Vegas much more comfortable. I would be thrilled if some kids out there grew up to be AC repairmen (I should say repair-people/repair-person etc and fumble around in the awkwardness of finding the right word that exists already, but I’m not from California–thank God!. I do people mean boys or girls though.)
