Shout out to Dalton who gave excellent service! Was told by another company that both my furnace and AC unit needed replaced. Got a second opinion with Capital City HVAC. Dalton did a thorough inspection and concluded it did not need replaced. Professional, knowledgeable, and most importantlytrustworthynot all are. He even cleaned the mess the other company left behind. Thank you, Dalton!
