Have you had your heat pumps routine service call performed?
One of the worst things about performing a commercial heating and air routine service call is the HVAC duct cleaning that is involved. This procedure requires someone that is not afraid of tight spaces and heights for that matter. Having to crawl up into the ceiling inside of a small box like passageway seems terrifying to many people.
This is why it is often hard to find a heating and AC contractor that is willing to perform this type of work. But this job is a must do especially for commercial buildings. If this area is not cleaned it can cause many more problems with the entire heating and cooling system.
So if you are thinking of finding a job in the heat pump and air conditioning repair industry I highly suggest that you not be afraid of heights or tight spaces. If you do have these fears you will need to overcome them or look elsewhere for a job that better fits you.
