I am giving Tru Tech Heating and Cooling 5 stars, because after spending the night in a house at 50 degrees I called my home appliance insurance company and they scheduled Tru Tech, even though they gave me a window between 2 to 7, I don’t care because when they showed up at my house the service guy was pleasant, and listen to my complaints and got to work installing a new thermostat one that didn’t require batteries so I will never have to touch for maintenance to change a battery, which is why my old thermostat no longer worked, because after taking off the cover several times over 7 years it got loose from the wall, this won’t be a problem ever again. My house is nice an warm, and I can now do something other than hide out under a mountain of blankets. Not sure if they accept credit cards, I gave them a check, but they probably do, because I signed an electronic receipt, so I will answer that as yes, but please confirm with Tru Tech.
