The technician called me back immediately and stopped by us on his way to another job within 30 minutes of the call.

I am happy to be working with a small, local business, and now I'm never turning back. Thank you Williamson!

Hello everyone, I want to give an enthusiastic 5 thumbs up for Williamson Heating & Cooling. Let…read moreme tell you why, Williamson has been my HVAC team for 17 years. 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. I once had an outdated furnace that would go out on the coldest days, Williamson has always been there for me. They arrive on time, clean up and are all very courteous. I have replaced a heating and A/C system with Williamson and there is no other HVAC team for me. I highly recommend my HVAC team. Williamson heating is the best!

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.

Wait until they discover their two-stage furnace was never installed correctly and that it's been…read morerunning on single stage for years. This was a serious oversight. 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.

We are both doing well, but the bill was a little bit painful for my wallet. (But very fair) Full Name: Lennox ML180UHE (Leni) Weight: 127lbs Height: 33" He is warm and already quite a comfort. I know we will enjoy years of happiness with Leni. The whole experience with Illiana HVAC was easy and professionally well done. My old furnace had a great life but reached the end of its service. Illiana understood my needs and got the install done in a few hours. Adam and Vaughan were fantastic with the installation. They were very professional, respectful and talked me through the whole process. I will use Illiana for all my HVAC needs.

Would definitely recommend using him.

ExoEdge Systems LLC was sent to my home to service the air conditioner. Instead of focusing only on…read morethe unit, their technician attempted to walk through the house and claimed he needed to check every vent in every room. When I declined, the technician later reported on the number of pets in my home which was unrelated to the service call. I invited this company in with the expectation of a professional HVAC repair, not a house inspection. I felt misled and uncomfortable. A contractor should respect boundaries and stick to the job they were dispatched for.

I was not able to be home because of work, but my girlfriend allowed him access to the water heater to inspect the issue. Without giving an assessment of the situation, or giving an explanation of the problem or an estimate on a fix, she was handed a bill for $180. No parts were replaced. The water heater still does not work. The invoice only indicates that the unit was "cleaned", but remains dysfunctional. The serviceman indicated that credit card payment was not an option, and that checks should be made out to him personally, instead of to Transite Heating and Air Conditioning. I feel like this whole encounter is suspicious and that they took advantage of the fact that I was not home to oversee the effort. DO NOT USE THIS SERVICE.

They came out promptly and were extremely nice, professional and honest. They fixed everything quickly for a very reasonable price. The first company we called tried to, I assume, take advantage of the hot temperatures and gave us an astronomically high quote (7x higher than Air Source 1), which we declined. I can't recommend Air Source 1 enough. We will certainly be using them for any and all HVAC needs in the future!
