HVAC reviews in Belleville, Illinois

Quality work at very reasonable prices. Excellent staff.

Great company to do business with. Honest and very friendly service!

Steve did an awesome job and was beyond helpful. Will absolutely recommend!

Matt was friendly and very knowledgeable. He also gave us some options on cleaning and inspecting the furnace.

The workman showed up on time but was not communicative at all. He finished the work without giving me a price. A month later I got a huge bill in which I did not agree to. I would not recommend this company.

My experience with this company has been nothing BUT professional. The price was more than fair and the service tech was respectable and nice . I recommend Keifer to anyone needing work done!!

Our landlord sent this company out to fix our furnace.
They called to let me know the time they were coming and showed up on time. They were very efficient, knowledgeable, and the most friendly people I have ever done business with.

We had matt come out and fix our ac, super nice and professional guy, really felt like I wasn't getting ripped off, or that they were trying to overcharge me for anything, helped me with questions and advice, would definitely recommend and use again

Matt and Drew were professional, personable, and worked us in quickly, even on a holiday. They are also knowledgable and have great prices. I would highly recommend them for all of your heating and cooling needs. Thanks guys!

I finally found a heating and cooling company that I feel like I can trust. This company will not gouge you or try to sell you something more than what is necessary. Matt came out to my home and went above and beyond my expectations. He was honest and you can tell he had integrity. Just from my conversation with him I’m quite sure the integrity is from top to bottom with this company. That’s so hard to find sometimes. I highly recommend.

This is a owner operated managed company. Very talented professional employees. Fair priced quality service. Has been serving my home's for 10 years. This year I decided to upgrade my furnace and central air. I would recommend Kiefer to anyone for all your H-vac needs.

A+++ Thank you for coming out on short notice. We have my elderly father living with us and were concerned about the heat due to our ac not working. Steve was able to get here and fix it quickly. He was quick, honest and was well skilled. Very happy with the service!

Andrew was very knowledgeable. He found a clogged vent. Andrew was personable. All Seasons is a local family business. They have worked on several family members a/c units & furnaces.

Excellent company. Andrew is always professional, thorough, and personable. I recommend them to everyone.

Technician is always friendly and respectful of the property. Always does a through inspection and cleaning of our AC unit and Heating system.

THEY REPLACED OUR HEATING AND COOLING UNIT.

Andrew was great so professional and friendly will definitely recommend

I can’t say enough about All Season Heating And Cooling. Our home warranty company contracted a company to install a brand new HVAC and they did everything wrong. I don’t wanna go into too much detail, but let’s just say nothing ran properly or was installed properly. We had to find a company that could reinstall everything affordably and efficiently. After contacting All Season Heating And Cooling, they literally showed up the next morning at 7:30 as promised and reinstalled all the equipment properly and even had a metal works in one of their vehicles to build a box to put the HVAC upstairs on so it could drain properly. So now it is winter and the heat is working amazing upstairs and we can’t thank Jeff his son, his wife and their team for amazing work and customer service. I would call nobody else. There’s something to be said about a knowledgeable family run company that really knows what they’re doing. For what we paid, we still got a lot of value out of our new HVAC. It was money very well spent

These guys are so amazing. I called at 8 am and they rushed out during the huge snowstorm and had it fixed by 930am , it was amazing service from the time they answered the phone til Andrew, the technician fixed it

Awesome service! Andrew is great, explained everything so well. They were at my home less than an hour after I called. Highly recommend!

Excellent service from a company that truly cares about its customers. Everyone we interacted with was kind, patient, and attentive. They went above and beyond to ensure everything was working perfectly. Highly trustworthy and dependable!
