Donvernon Heating & Cooling

I do not recommend this company. Our A/C was not cooling to the set thermostat temperature. The tech they sent examined and cleaned the exterior unit, checked the filter, even removed the thermostat and claimed the wires needed tidying, and ultimately replaced our perfectly good thermostat claiming it was faulty. None of this improved our cooling at all. They offered to send a different tech and adjust whatever new fee might be incurred but we declined. $300 spent for no improvement and no answers. One star because he was courteous. Editing to add: later now in October the living room thermostat that normally controlled both our heating and cooling no longer controls heating. It seems the tech’s wire “tidying” changed the heating control to the basement thermostat. I doubt this was intent

I'm out of work and having trouble with my furnace, this company helped me out and was able to keep costs within my budget with my 25 yo system. Thank you so much, I have heat and this is a huge worry off my mind.

Called about 5 days ago because our boiler stopped working and they came, assessed the problem and we are already back to heat! Adorable fix as well!

The service agent got my furnace working again. It's working great. Great job.

Great service great price. The young man that came out to my house new what he was doing and was very good at explaining everything to me. I highly recommend this company to everyone with central air or Heating problems. Well done
