They are extremely efficient, wonderful to deal with and knowledgeable in every aspect of their work. The owner, Pat, is a woman of integrity and conscientiousness, eager to please the clients.

I told the tech that it smelled unusual and the breaker was smoking. He managed to turn off the breaker and said to call an electrician. If he had some kind of knowledge and used his brain, he would not have turned it on in the first place! He almost caused a fire! I first called for an electrician and then called the company. The owner was no help at all! He did not admit any wrong doing for his worker. I would not ever recommend this business to anyone!

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.
