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 15,256 housing units in Crystal Lake, with 1990-1999 as the largest build-era cohort at about 26.2%. 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 1986 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 Crystal Lake’s housing rangeWith roughly 15,256 estimated housing units, Crystal Lake 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 1990-1999 at about 26.2%; that still leaves most homes outside a single construction wave.

Real feedback from local homeowners who called McHenry Heating & Air.
We called McHenry Plumbing on Friday to get an estimate to repair the hot water heater issue and discussed the situation with them. Based on the quote we received and age of the unit we decided to replace it. They scheduled us on Monday. The two plumbers arrived when scheduled and were professional and pleasant and were finished in about 2.5-3 hours. I would recommend this company and will use them in the future if we need their services.
Excellent service! Our sump pump went out and we had water in the basement, McHenry Plumbing (Heating & Air) sent Butch over asap. I can't say enough about Butch, he was excellent! He took the time to explain everything to me, such a nice guy, very professional and great to work with! Thanks so much!
