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.

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
