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 hvac zoning & smart thermostats.
Every home and system is different. These answers help you prepare; an on-site diagnosis confirms the right next step.
Ask another questionCan any smart thermostat work with my system?
No. Wiring, equipment stages, accessories, power requirements, and communication protocols must be compatible.
Will zoning fix every uneven-temperature problem?
Not necessarily. Duct design, airflow, insulation, equipment capacity, and building conditions should be considered first.
Can you help set up schedules and controls?
Yes. Installation can include basic setup and an explanation of normal control operation.

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
