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!

Straight answers
Common questions about furnace maintenance.
Every home and system is different. These answers help you prepare; an on-site diagnosis confirms the right next step.
Ask another questionWhen is the best time for furnace maintenance?
Before sustained cold weather is convenient, but overdue equipment can be checked at any point in the season.
Is a filter change the same as a tune-up?
No. A filter is important, but professional maintenance also reviews operation, controls, airflow, and equipment condition.
Can maintenance find safety concerns?
A maintenance inspection can reveal visible or testable concerns that deserve correction, though it cannot predict every future failure.

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.
