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.

As a single girl, y'all know it's hard to find good help. Wayne and his dad are AWESOME! They've installed and maintained my HVAC system with consistent excellence.

We called Summers on a Sunday (the Sunday before Memorial Day). It was 90+ degrees and our air…read moreconditioner made a grounding noise and would no longer start. The company who installed our Carier unit isn't open on Sundays so I called Summers due to the positive Yelp reviews. The service call was $150 to come out and look at it - totally understandable. The service tech listened to my son explain what happened and where on the unit the sound was coming from and it was quickly diagnosed and working within 5 minutes. Great right! BEFORE the guy fixed it, my husband asked how much it would cost. The guy said $200. We looked up the part on-line and it was $10 so we figured $150 for the service call and $50 for the 5 minutes it took to diagnose and install the $10 part. The bill details read the following -》trip charge $49 + Dual Cap installed $190 + $159 comfort plan agreement for a whopping total of $398. $200 over the quoted price of $200 OR $50 over if you add the $200 + $150 trip charge. When I questioned the bill, the tech just kept telling me how great the comfort plan was and gave me zero option of not purchasing it. In essence, I purchased an agreement NO ONE told me I had to buy either before they came out or before they would repair it. I was the told the agreement included a 2 year warranty on the part and labor along with a free fall cleaning of the air conditioner, the furnace (that was just cleaned) and a water heater flush. I don't even own a water heater! I have a boiler. Frankly, I am leery of having them back to 'clean' anything because it will just lead to more hidden fees.

If a two-stage furnace was wired or set up incorrectly and only ever ran in single-stage mode, the homeowner probably missed out on: Comfort benefits - two-stage furnaces are designed to run on low most of the time, giving more even heating and fewer temperature swings. Efficiency - the furnace likely used more gas and electricity than necessary. Longevity - constant high-stage operation puts more wear on components than normal two-stage cycling. It would worth having a qualified HVAC tech inspect the wiring, thermostat settings, and control board configuration.
