Ty-Mark Heating & Cooling - Eliot's Certified HVAC Repair

Common signs include reduced cooling power, longer run times, ice forming on the refrigerant lines or evaporator coil, and a noticeable hissing sound. Since refrigerant is essential for heat transfer, a leak makes your system work harder, increasing energy bills. If you suspect a leak, call us for professional leak detection and EPA-certified repair to protect your system and restore efficient cooling.

A cracked heat exchanger is a critical safety issue. It can allow carbon monoxide, an odorless and dangerous gas, to mix with the air circulating in your Eliot home. Signs include a strange, metallic smell, soot around the furnace, or visible cracks in the flame. We perform thorough visual and instrumental inspections during our tune-ups to catch this early, ensuring your family's safety and preventing costly furnace failure.
