The technician was friendly, polite and very careful not to track dirt in by wearing shoe covers when entering my house. He was very thorough. I would definitely recommend De Hart. Services: A/C system repair, A/C system maintenance

DeHart installed our Bryant HVAC system in 2008 and today did first check of three in their Loyalty Program to make sure heating, air and thermostat are in working order and yes, finally replacing our 1978 installed 40 gallon gas water heater with an updated tankless system. Carlos explained all.

I was happy with the service. However approx $550 for maybe 1 hrs work tops is quite a bit of money. All that needed to be done was install a new cartridge. I'll have to think about using them again at these prices Service: Shower repair

They called to verify appointment, they called to let me know technician was on the way, when he showed up, he (Tyler) was outstanding. Explained what was wrong how to fix, suggestions about maintenance specials, straight professional yet friendly. Made us both glad we use DeHart. They have done an excellent job for us, 20 yrs in house, needed to replace hvac they did, needed new condenser, they did, then needed new water heater! Top notch! Thank you DEHART!

Michael was professional, courteous and pleasant to talk to. He performed the maintenance on our air conditioner and honestly shared information that would enable us to enjoy a "cool summer" without any issues. I'm very happy with the service DeHart has provided to us this past year. I will continue to use this company for any issues concerning heating/air conditioning, and water heater mainenance.
