WHAT PEOPLE SAY

Marsha Lucus-Conway

I just had Terry Hartzell with Hartzell Heating & Air. He was super nice. He was very thorough. After a deep inspection he determined it was not my furnace it was my thermostat. Went to Lowe's got a new thermostat and we are up & running

Jenifer Monteverde

We had Joey from Hartzell Heating and Air out to do a general inspection on our ancient household heating system. While he was here he detected and adequately fixed gas leaks that were detected. He also ensured that our blower motor was functioning properly and that our heater would in fact be in working order for winter. We truly appreciate the time Joey took to show us and explain to us the issues he found and are happy he fixed the issues swiftly. 10/10 would recommend Hartzell Heating and Air.

HS Lange

Joey @ Hartzell is great! We're on the service plan, so we try and stay on top of any furnace or AC issues that could come up. Joey is very clear about what maintenance is vital, and what elements are okay to be monitored, for now. He explains things well, and is thorough. Scheduling with Rachel is quick and easy and communication is very good!
