HVAC reviews in Steeleville, Illinois

Great experience. The installation crew did a great job and were very friendly. They did well explaining how things worked. Had the new system for almost two months now and our house has NEVER been this comfortable during the summer the 11 years we've owned it. Very happy!

My husband & I have a winter & spring maintenance agreement with Williams. Today, we had spring maintenance for our air conditioning. Jackson Brand, our service technician, definitely a 5 star employee, & James, were very professional, knowledgeable & courteous. They replaced our filter & our contactor. I was very impressed & highly recommend Williams Heating and Air Conditioning.

Great service. My furnace quit on a Thursday night. I called them Friday morning about 8:30. She sent a mechanic right over and it was repaired by 10:30.
The mechanics were really professional and very friendly. Couldn't ask for any better than that.

As always Williams HVAC does it again. In the past I have received excellent care during routine inspections and especially during emergency conditions. The gang does great work. Brandon did a great job with my humidifier install. Respectful and quiet as he worked away this morning. Very professional. The whole gang at Williams does great work. Thanks Brandon

Williams Heating and Air did a great job installing our new gas furnace. They communicated well, were considerate of my home, cleaned up after themselves, and were extremely professional. They exceeded my expectation. I will definitely use them in the future and will recommend them to friends and family!

Williams has always been a great service to our home. They are extremely professional and courteous. Frank H has made a few service calls for us and is more than helpful. He knows that unexpected problems with an air conditioner causes stress to the customer and has a calming demeanor while providing good honest service. No add on or hidden fees. Just good quality service

Brandon and his team from Williams Heating and Air did a great job installing a completely new HVAC system in our home. They arrived promptly, got right to work and cleaned up when they finished. Brandon answered our questions and made sure we understood our new smart thermostat. Everyone was professional, friendly and polite. We were very impressed and highly recommend Williams Heating and Air.

Staff is very knowledgeable. Service was great and they made sure to come out in a timely manner. Even on weekends
