Miller’s Area Htg. has been our “go-to” HVAC company for several years.

“Miller’s Area Htg. has been our “go-to” HVAC company for several years. Dependable and trustworthy. Our AC started struggling last week so I obtained several proposals for a replacement. Holly, Miller’s Project Mgr., came out the next day. Her knowledge and professionalism was outstanding.

We purchased a 2 stage variable speed, 4 ton air conditioner and a 95V furnace. Holly took care of the paperwork and obtained the village permit. Everything was installed today by Mike, Oney (our friendly regular technician), and Sean in a matter of only 8 hours. Their workmanship was impeccable. They removed all of the old equipment and performed a clean up of the work areas. Mike, the lead installer, took the time to update me on their progress throughout the day, walking me through the new included wi-fi thermostat, and completing a checklist and walkthrough at the conclusion of the job.

They made sure that there were no questions left unanswered before they left.

I’m now enjoying the comfort of our new AC thanks to Miller’s Area Htg. and Air Conditioning. Thanks very much!

1/9/19: I should have also mentioned that when the building inspector came for the final approval, he was impressed by the workmanship by Miller’s.”
