Our 17-year-old furnace died on a very cold holiday weekend! 😭 Jeff was SO KIND and came out twice on Saturday. We ended up needing a new furnace and he got it all arranged and let us borrow a space heater. Russ and Neil were great and installed it on Monday. Cassie got the permit with the city and the whole process was smooth and easy. Communication was fantastic. They were even nice to our crazy dogs. So grateful to have a warm house again! We trust McHenry Heating 100%! Thank you!

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 12,095 housing units in McHenry, with 2000-2009 as the largest build-era cohort at about 21%. Those figures help frame useful questions; they never replace an on-site assessment.
A more specific McHenry detailMcHenry's official history describes 1920s resort growth, summer cottages along the Fox River, and its continuing 'Heart of the Fox River' identity. Mix river-corridor and former-cottage context with the city's later housing growth; avoid portraying the whole city as waterfront.

A local planning lens
What the public data suggests—and what it cannot tell us.
- 01
Start with the 1988 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 McHenry’s housing rangeWith roughly 12,095 estimated housing units, McHenry contains enough housing variety that equipment age and prior renovation history matter more than a citywide assumption.
- 03
Use McHenry County data carefullyThe largest reported cohort is 2000-2009 at about 21%; that still leaves most homes outside a single construction wave.

Real feedback from local homeowners who called McHenry Heating & Air.
My furnace went out and they came the next day. I had to replace it and they gave me a good price and installed the next day during the ice storm. They were kind enough to let me borrow a generator and a heater for the night so my pipes wouldn't freeze. They went the extra step for me. I would definitely recommend them!
I have been a customer for almost 10 years now and there is no other company I would trust with my Heating/Cooling/Water heater needs. Over the years I have purchased a Water Heater, new Furnace, and new air conditioner, never an issue. The team is professional, courteous, knowledgeable, and just really easy to work with. I have always had a service plan on my system and one of the great things is the longevity of the staff. I have had Tony as my service tech now for i would say 3 years in a row. There is something comforting about always seeing the same person year after year knowing that they not only know your system but they know you. Thanks Mchenry Heating and Thanks Tony
