ATC Labor Warranty
Every ATC new equipment installation comes with a 3-year, 5-year or 10-year labor warranty! The 5 and 10 year warranties even include refrigerant! This warranty is in addition to the manufacturer’s 10 or 12 year parts warranty. To maintain our full-coverage warranty, as per manufacturer recommendations, an annual tune-up/inspection of the equipment is required.

Regular maintenance is key to prolonging the life of every HVAC heating and cooling unit. Our maintenance programs are designed to keep your systems running efficiently, saving you money and preventing unexpected breakdowns. With our tune up and service maintenance plans, we fix problems when they are small and before they grow into big problems!.
