“Best experience I have ever had. Jason was extremely professional from the first call. They gave me an excellent price for both my air conditioner and furnace. Jeremy showed up on time. He walked me through everything. Communication was great! My place was cleaner when they left than before they got there. Upon completion, we went through everything he did, the warranty and future maintenance. Definitely give these guys a call, you will not be disappointed!!“

“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).“

“Patrick is great! We recently had a new system installed and needed to put in a service call. They were able to fit us in the same day and communicated clearly before his arrival. Patrick was friendly, knowledgeable, and quickly diagnosed and fixed the problem. Excellent service all around.“

“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!“

“Chase Martin came out on a Sunday for an emergency call on one of the hottest weekends of the 2023 summer. He found that the blower on the furnace had failed. Being a holiday weekend, the part could not be found until Tuesday. Chase gave me ideas on how to keep the house cool and carried my very heavy dehumidifier up the stairs to help my living room feel cooler. He was conscientious, kind and apologetic that he couldn't help me right away.“

“Phenomenal customer service and response time. During the 90 plus degree heat wave my AC thermostat skyrocketed. My house was only getting hotter. AirTech came to my house extremely fast (within an hour) and fixed my air conditioner on the spot. Highly recommend!“

“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.“

“I left to go on a fishing trip in Canada and my furnace went out so the A/C couldn't blow and S&R put a new unit it in while I was gone and I came home to a nice cool house on a 98° day. Thank you!“

“Had our A/C Compressor go out in the dog days of July. Got a couple quotes before Mike. Not only was he the most affordable, but he was the MOST RELIABLE, Communicative and most of all Dedicated. Turns out our Coil was also bad in the furnace. Mike exhausted all options before having to replace the Coil. Truly a master of his craft. THANKS MIKE!!“

He not only fixed the problem in under an hour, he explained the issue in detail to me and what he was doing to remedy it, also in detail. The price was fair and I couldn't recommend him more!“
