I heard a bit of a funny noise coming from our HVAC system a few days ago, and it was this sort of different screeching noise. It gave me a bit of a fright and while our temperature control system did not completely give out on me at that moment, I knew that whatever made that noise needed to be checked out buy a certified HVAC serviceman. I did not pricey losing the benefit of our a/c in the middle of the summer, as it is. I had had preventive maintenance done a couple months prior to prepare for the Summer season, however I still wanted to call out an HVAC serviceman anyway. I need an appointment for the HVAC tech to come out a couple afternoons later. The HVAC repairman was punctual and he did not take long to get to work and try and find the source of the noise. Thankfully, he discovered that the concern was minimal, but that was only because I called him out as early on as I did, however a piece of mechanical component and come loose and it was making the squealing noises. If I had sat on it and not addressed it as soon as I did, that loose component may have honestly well cost of a much greater concern with the inner workings of our HVAC system. The part was abruptly tightened back into site by the HVAC tech and it did not even cost me all that much! I am so grateful for good HVAC maintenance in our town!
