My old system was having problems and my wife and I decided instead of continuing to throw money into it, we would look into replacing. Dodrills sent a man out that day, gave us options and we decided on a unit. They were there the next day to install our new unit. The guys were very nice and professional. We did have some problems with the thermostat they installed. I called and the sent a man out that day to check the system and replace the thermostat, Working great now. Would recommend Dodrill for your HVAC problems.
