Used them for years and they never disappoint. Latest service was AC refrigerant top-off and condenser cleaning. Always thorough and fairly priced HVAC service nearby. (Houston)

Got quotes from 4 companies for a new system. Douglas Mechanical, Inc. wasnt cheapest but they were the only ones who properly sized the unit for our square footage instead of just replacing same-for-same. That matters.

Old unit was on its last legs. They quoted us fairly, scheduled within the week, and had the new unit running by 3pm same day. Impressive HVAC efficiency. (Houston)

Our AC died during a heat wave and they had a tech out within two hours. Diagnosed a bad capacitor, replaced it on the spot, and we had cold air again. Lifesaver HVAC service. (Houston)

Added a zoning system so upstairs and downstairs have separate temperature controls. Game changer for comfort. Excellent HVAC upgrade for our home. (Houston)
