Repairing HVAC systems is something I love doing. I work as a freelance heating and cooling expert. Additionally, when business is slow, I work on the side of a nearby heating and cooling company. I was recently assigned to a job to repair a rooftop heating and air conditioning system while I was employed by the local heating and air conditioning company. At my independent heating and air conditioning company, I would never take on this. Because the rooftop air conditioning and heating systems are less common, they are more challenging to repair. Additionally, when I was in heating and cooling school, I was unable to learn anything about rooftop air conditioning and heating systems. So I have to just wing it and hope that I can get the rooftop HVAC systems fixed in a reasonable amount of time when I’m working my part-time job at the local heating and cooling company. I typically do it because I am accustomed to doing it and have done it numerous times. But I really do not enjoy having to go out there and fix one of those rooftop heating and cooling systems every single time. like the time they sent me on a job for that the previous week. It ultimately took me almost twice as long as it would have for a skilled rooftop HVAC repair specialist. But thankfully, I made it through without getting into any trouble. I just sincerely hope that I never have to fix another one of these rooftop heating and air conditioning system units again anytime soon.
