We’ve had McHenry Heating and Air come out for the last couple years for maintenance, troubleshooting, new equipment, etc. Now that we’ve had nothing but positive experiences with them, it was a no brainer to join their maintenance plan. This time, Chris came out for a fall inspection and was prompt, very friendly, and cleaned up afterwards. Great service!

I purchased and installed a new furnace and A/C system with a smart thermostat during the pandemic and have enjoyed trouble-free operation ever since. It is super efficient and quiet. I subscribe to their maintenance plan which has proven to be of great value.<br>During the latest maintenance visit, their tech KC Allen tweaked the settings which made an improvement in cycle times and overall operation. Now it's even better!<br>I have been pleased with every interaction involving McHenry Heating & Air.
I used McHenry Heating and Air for the replacement of our furnace and A/C. I'm on the maintenance plan, and regularly receive great service. Chris serviced my A/C today. He was very friendly and respectful.
