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!

Local housing context
Service that accounts for the home’s history.
A mature housing base makes replacement planning, airflow balancing and evaluation of original ducts or piping especially useful.
The Census estimates roughly 1,720 housing units in Wonder Lake, with 2000-2009 as the largest build-era cohort at about 21.2%. Those figures help frame useful questions; they never replace an on-site assessment.

A local planning lens
What the public data suggests—and what it cannot tell us.
- 01
Start with the 1970 medianCheck original ducts or piping alongside newer equipment so one generation of the system does not hide limits in another. The median is context for the first questions, never a shortcut around an on-site assessment.
- 02
Account for Wonder Lake’s housing rangeAcross roughly 1,720 estimated housing units, multiple build periods can create very different repair and replacement priorities from one address to the next.
- 03
Use McHenry County data carefullyThe largest reported cohort is 2000-2009 at about 21.2%; that still leaves most homes outside a single construction wave.

Real feedback from local homeowners who called McHenry Heating & Air.
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.
