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.

In May 2025, we needed an outside spigot replaced. The technician was here for less than an hour,…read moreyet the charge was $454.00. Then in October 2025, we had our kitchen sink drain snaked. Two technicians came, spent about 30 minutes, and charged $373.00. The drain is still not fully clear--water backs up from one side of the sink to the other, and I usually have to run the garbage disposal just to get it to go down. Today, I called to schedule service for a leaking washing machine hookup and to have the kitchen drain looked at again. Nathan informed me it would be $350 just for the service call, before any work was even done. This amount for an appointment is exorbitant and disappointing, especially for a returning customer. Between the steep service call fees, the price increases from May to November, and the unsatisfactory work, I can only conclude that this company is price gouging. I would not recommend them and will never use their services again.
