“McHenry Heating and Air has been my first choice HVAC and Plumbing for my home and rental properties. I tried many in the area before them and they are the best and have been using them for last several years. Recently had an HVAC emergency call at 10 pm and technician worked until 2 am to get the furnace going. Service calls and installations have always been affordable and they can't be beat with how they back up what they do. Same for the plumbing side of the business which I also call them for (wish plumbing had weekend hours but you can't have everything).“

“We have been using Jett’s For the past few years for our annual furnace cleaning. We had them come out end of August and this time we received a “Surprise, You need a whole new furnace!”. Scheduling was super easy, Hannah at the office was a delight to work with! The three gentleman that came out to do the work were kind, courteous, and knowledgeable. Our furnace is in our dirt crawl, so I would imagine it wasn’t an easy job, But they did not grumble about it at all, even told me they have seen worse! We highly recommend Jett’s heating and cooling for any of your heating and cooling needs, and they have gained customers for life with us!“

“American Comfort Central did an outstanding job installing my new A/C unit. From start to finish, the experience was excellent. Jacob and Cade were absolutely top-notch—professional, courteous, prompt, and incredibly efficient. They took the time to explain things clearly, worked with great attention to detail, and were so respectful of my home. I was especially impressed with how clean they worked—when they left, the space looked even better than before they started!

It’s rare to find a company and team that you can fully trust, but American Comfort Central truly delivered above and beyond. I highly recommend them to anyone needing HVAC work and will continue to use them for any future needs.“
