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.
Newer housing can still reach first- or second-system replacement windows, with controls, indoor air quality, maintenance and careful equipment matching becoming priorities.
The Census estimates roughly 6,627 housing units in Round Lake, with 2000-2009 as the largest build-era cohort at about 59.6%. 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 2003 medianConfirm equipment matching, controls and maintenance history before assuming a newer structure needs only a like-for-like solution. The median is context for the first questions, never a shortcut around an on-site assessment.
- 02
Account for Round Lake’s housing rangeAcross roughly 6,627 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 2000-2009 at about 59.6%; 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
