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 indoor air quality.
Every home and system is different. These answers help you prepare; an on-site diagnosis confirms the right next step.
Ask another questionWill one product solve every air-quality concern?
Usually not. The right combination depends on the concern, HVAC system, home and occupants.
Can better filtration restrict airflow?
Yes, if a filter is not matched to the system. Static pressure and filter sizing matter.
Do you assess indoor air quality?
Yes. The company advertises indoor air quality assessment and solutions.

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
