Same day service.<br>Jeremy is our Heating and air technician, and he also services our on demand Water Heater. Great guy and excellent at his job!! Love this Company!

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 9,374 housing units in Zion, with 1939 or earlier as the largest build-era cohort at about 17.9%. 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 1971 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 Zion’s housing rangeWith roughly 9,374 estimated housing units, Zion contains enough housing variety that equipment age and prior renovation history matter more than a citywide assumption.
- 03
Use Lake County data carefullyThe largest reported cohort is 1939 or earlier at about 17.9%; 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!
