In the summers in between my college years, I worked as a repairman. We had a huge heating and air conditioning systems that needed constant babying in the sweltering heat of Indiana summers. I was the nanny to these heating and cooling systems. As the in-house repairman, I was able to perform some of the basic repairs and maintenance operations for the heating and cooling system, but it got complicated. Air conditioning repair can be an infinitely complex endeavor, depending on how much precision you want to apply to a given air conditioning unit. Because I was just a college kid trying to make a few bucks in the summers, I was far from an expert. Thus, I became fast friend with the local heating and cooling company in our town. While the industry has two elements in the name (‘heating’ and ‘cooling’), I learned from those summers that it is far more that just two simple things. There are a lot moving parts when it comes to these machines. That is why it is a handy thing to have a good relationship with a heating and cooling company that can do it all. Find a company that is versatile enough to work on any and all heating and cooling systems. You are going to be happy if you find your Jack-of-all-Trades company. Heating and cooling systems are usually lumped together because, from it outside, it seems that they both deal with temperature regulation indoors. And in one way of looking at things, they have some similarities and overlaps. But when you get down into the details, they are quite distinct systems. Even different heating systems function differently. Some use Freon. Some use coils. Some use refrigerant. It can be quite complex. When you find a repair company that has been in the industry for a long time, they will be able to navigate all of the different systems, no matter the model or year. In terms of research and development, we have made huge jumps in terms of understanding how our technology has an impact upon the environment. The way that we used to make cars or run air conditioning units were found to be bad for the environment. While it is a good thing that these discoveries were made, it also means that we changed the way that heating and cooling systems run. That means that just about every year, the design of these systems is tweaked a bit. A versatile repair company ought to be able to understand and fix whatever you throw at them. I know that I certainly had to rely on a versatile company during those summers. Half of our building had been added on to years later. That meant that even on the same building, we had two vastly different heating and cooling systems. But I made it through those summers with the help of a heating and cooling repair company that knew the industry, had years of experience, and understood the technology well enough to navigate even the most confounding dither.
