I have been very happy with the furnace they installed 3 years ago. In June, I got a new AC unit. KC came out to inspect the old one and told me it would be best to replace rather than repair. As usual, everything was explained to me completely. Josh and Luis did the installation perfectly. Dot came by to do a final inspection. Everyone works as a great team, and I will continue to trust them to do a fantastic job.

24/7 emergency HVAC, planned comfort work and residential plumbing from a family-owned company based in nearby McHenry.

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 5,998 housing units in Fox Lake, with 1970-1979 as the largest build-era cohort at about 26%. Those figures help frame useful questions; they never replace an on-site assessment.
A more specific Fox Lake detailFox Lake sits on the south shores of Pistakee Lake, Nippersink Lake, and Fox Lake in the Chain O'Lakes system; an official village source says about 20% of its area is water. Waterfront and lakeside-home context supports sump-pump, humidity, corrosion-awareness, and seasonal-property maintenance themes without claiming those conditions at every address.

A local planning lens
What the public data suggests—and what it cannot tell us.
- 01
Start with the 1978 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 Fox Lake’s housing rangeAcross roughly 5,998 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 1970-1979 at about 26%; that still leaves most homes outside a single construction wave.

Real feedback from local homeowners who called McHenry Heating & Air.
Work was done professionally. The AC/ Furnace replacement installation was done while I was busy doing my own job which was very convienant. Other than the working unit you would never have known they were there. No scratched up walls from hauling the large units up and down stairs. Nothing went missing. No messes were left behind. And the follow up interview with Dot a few weeks after install was informative and pleasant. You get what you pay for: quality.
We had a great experience with this company. We called during a very hot week when our 22 year old ac unit no longer cooled the house properly. Service technician Jeremy arrived and diagnosed the problem and discussed with us our options. We decided that a new unit was the best plan. The next morning installation technicians arrived. Dot followed up with us assuring our expectations had been met. Customer service with this company is top shelf. We had a new unit cooling our house in less than two business days from our initial service call.
