Excellent experience from start to finish. James was very informative during the quote process and provided multiple options. Cole and Jay showed up on time and got right to work. They were courteous and did excellent work. Everything was tested and cleaned up before they left. I highly recommend using McHenry Heating and Air.

Straight answers
Common questions about whole-home ventilation solutions.
Every home and system is different. These answers help you prepare; an on-site diagnosis confirms the right next step.
Ask another questionWhy not just open a window?
Opening windows can help temporarily, but it is uncontrolled and may add outdoor humidity, heat, cold, or particles.
Will ventilation affect heating and cooling?
Yes. Outdoor-air volume and controls should be planned with the HVAC system and local seasonal conditions.
Is ventilation the same as air cleaning?
No. Ventilation exchanges air, while filtration and air cleaners address particles or other specific indoor-air concerns.

My experience with the service tech and the installation team (needed to replace a 26 year old Trane) were top notch. This was my first time dealing with McHenry HVAC but they are my go to dealer now. Fair pricing and as it turned out next day installation.
Absolutely the best this is the second time we have used them and their price was fair and Chris did an excellent job getting our heat working on the coldest day of the year thanks McHenry Heating and cooling
