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.
Late-20th-century housing naturally brings second-cycle HVAC replacement, efficiency upgrades and proactive plumbing maintenance into the conversation.
The Census estimates roughly 1,364 housing units in Deer Park, with 1980-1989 as the largest build-era cohort at about 25.6%. Those figures help frame useful questions; they never replace an on-site assessment.

What the public data suggests—and what it cannot tell us.
- 01
Start with the 1989 medianCompare repair history with second-cycle replacement timing, controls and current efficiency goals. The median is context for the first questions, never a shortcut around an on-site assessment.
- 02
Account for Deer Park’s housing rangeAcross roughly 1,364 estimated housing units, multiple build periods can create very different repair and replacement priorities from one address to the next.
- 03
Use Lake County data carefullyThe largest reported cohort is 1980-1989 at about 25.6%; 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.
