Installers did a great job. Figured out a way to mount the thermostat in a challenging place in my older home. They were respectful of my space, went above and beyond to help me, and efficiently installed my new furnace/thermostat/humidifier.

Fast and Easy Complete HVAC Replacement
August 21, 2019
Our 20 year old HVAC system stopped working on a Sunday evening. The next morning I called Harker to schedule a tech appointment. Much to my surprise they were able to come that Monday. Due to the age and condition of our equipment we decided a complete replacement was the best path forward. Harker scheduled the entire system replacement for the following day. Two techs came out in the morning and by the time I got home from work my system was up and running with the house at comfortable 74 degrees. A+ service.

We came home after 7 weeks of vacation to fine that our furnace was not working. I called Harker and they were there in 20 minutes and got our furnace working enough for us to stay in the home. We decided at that time to install a new furnace because the repairs would be costly. Harker was there the next morning and installed a new furnace and everything is working well now.

Unfortunately our furnace had a failed secondary heat exchanger and needed replacement. Harker diagnosed, advised, and spent extra effort to answer my technical questions about the new furnace. Installation was timely and professional.

Replace a 16 year old Trane furnace with a new carrier.
February 07, 2018
Harker Heating and Cooling have serviced our furnace and air conditioner for the past 6 years. Our furnace has been having issues for some time now and rather than repair it one more time, we decided to replace it. It was 16 years old...a Trane. Tim, Eric and Wayne did a fantastic job, fairly quickly. Their knowledge and service was great.

I had Harker come out to perform an annual heating check and unfortunately for me, they had to turn off my furnace as some out\-take thing was putting out too much carbon monoxide. I had to replace my furnace! Luckily for me, I had the furnace checked that day. NOBODY died and the furnace did NOT blow up! In addition, Harker had the right type of furnace in stock for my house AND they had workers available to install it. I am forever grateful to HARKER! Thanks. d
