Hello! I would like to offer you a warm (or should that be cool?) welcome to my new HVAC blog. I wasn't very interested in HVAC until I began to have some problems with my air conditioning system. It all started when the HVAC system started to make a strange noise. It would keep me up at night and it really started to ruin my day as I was too tired to do anything. Then, the air con started to blow hot air out of the vents rather than cool air. At this point, I called in an HVAC expert who explained to me exactly how the system works and the steps I needed to take to solve the problems I was having.
