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.

Carlos at Mr. Freeze has been taking care of our home for years. They have installed a new water…read moreheater, air conditioner and most recently a new furnace, not to mention the service calls they took care of at a moments notice. 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.

Horrible experience, requiring payment up front was my 1st red flag but I needed service today so…read moredecided to schedule a service call. They sent a kid who tells me the issue may be a cracked heat exchange & carbon monoxide leaking because I told him I had gotten dizzy before he arrived. Instead of telling me at that point he doesn't have the proper equipment to detect a CO leak he runs out to his work truck several times looking for equipment he knew he did not have. When he finally comes clean about not having the equipment he needs, he says for me to call the Fire Dept. because they have the equipment. I'm foolishly thinking YOU ARE A HEATING REPAIR COMPANY if you don't have the equipment someone in your company should right? WRONG!! I called the owner who tells me they tell all of their customers in an instance like this to call the Fire Dept. Owner proceeds to say, because the kid drove here, spent 45 minutes removing screws which he should not have & feeding a camera with as the kid put it, "not very good picture" in the furnace he earned the fee. Kid told me furnace had rust. I had to call a reputable company and the Fire Dept. who both confirmed no CO. Real repair guy says there is no crack and showed me pictures of inside furnace with NO RUST. Thank God furnace is running properly. Not only did these guys make off with $141 of my money but had nerve to say once Fire Dept. comes out call them back, here is your call back!!!
