I have used AHR Mechanical Services for three years now. Darold visited my home on 12/08/2017 to install a new thermostat (based on a lengthy phone call with me, Darold determined the thermostat was probably no longer working and needed to be replaced). After inspecting my heating system, Darold determined that the thermostat had been damaged by an issue that was caused by the AHR tech that had visited my home in mid-November to conduct the fall inspection. Darold corrected the mistakes caused in mid-November and did not charge me for any of the work Darold performed to get my heat pump back in working order.
