Even though we hadn't adjusted the thermostat settings, we were unable to understand why our energy…read moreexpenses had been gradually increasing each month for some time. We requested a comprehensive home energy assessment from this company. They went above and beyond what I had anticipated, a simple once-over. The professional tested HVAC performance, insulation levels, duct leaks, and even conducted a blower door test to find leaks and drafts for several hours. He compiled a list of fixes based on potential savings and produced a detailed report including thermal photos. We improved the attic insulation and sealed the ducts. The improvement has been amazing--the home stays more consistently conditioned and our heating and cooling system operates less frequently. We have already observed a 25% decrease in our utility costs. In addition to selling us equipment, They truly stand out for their expertise and transparency.

Their technician performed a thorough inspection, identified airflow issues, and made adjustments that improved comfort in every room. He even checked my furnace and ductwork to ensure everything was running efficiently. Honestly, the difference has been incredible - no more cold spots or constant thermostat adjustments. He was professional, knowledgeable, and truly dedicated to customer satisfaction.

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.

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.

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.

On the appointed day, Jim and Dave showed up on time, and worked all day to get everything installed. They were polite, prompt and obviously knowledgeable.
