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 I once had an outdated furnace that would go out on the coldest days, Williamson has always been there for me.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!

The receptionist should be let go or my time should be compensated due to inefficiency as a secretary on several different levels. I do not recommend. Find another company don't use this one.

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.

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.

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.
