STI Heating & Air Conditioning saved me so much money! I had another HVAC company looked at my…read morecentral air unit because it was blowing lukewarm air. The other company told me I needed a new compressor for $1699 and they took only cash. After a repairman ran off with $453 of my aunt's cash, I decided I did not feel comfortable giving the HVAC repairman $2000 (with labor) in cash. So, I told him I would seek a second opinion. I called STI Heating & Cooling who were booked for the week so I made an appointment for the following week. Ted arrived on time and was very professional. He took a look at my unit (which is 42 years old) and told me I needed a Hard Start Capacitor for $173. He also checked the amount of Freon (R22) told me I might need a little. He installed the capacitor and added a little Freon and my unit start blowing extremely cold air. Ted's work was great! He told me his father had an old unit like mines and he keeps him father's unit working. I told Ted the other repairman thought I needed a new compressor and Ted suggested maybe the other repairman was not familiar with older units like mine. I am SO glad I called STI Heating & Cooling! I told Ted they are now my go-to company for ALL my HVAC activities. I would highly recommend this company - they proved to be a huge money saver for me.

His staff are very professional and really nice to work with. We have an oversized 80 gallon water heater because of our Jaccuzi bathtub and they replaced it fast and perfectly. Our old furnace was in a tight space in the laundry room but Bob made it look so easy replacing it with the new one. They had to reroute some pipes and had no problem with it and made the area look like neat. Carlos also installed a Smart thermostat and we love it. We can control our house temperature while on vacation and have the peace of mind that everything is running as it should. And I know I mentioned the service calls but Carlos is very committed to them. We have had an issue at night that could've waited until the next day but Carlos insisted on coming out right away to take care of it. I am one that does my research and you can't beat the price of product and professional workmanship from this company. I could go on and on but hopefully this review will help someone get great service and have a comfortable house to enjoy.
