HVAC Services in Warminster, PA 18974

When the AC runs but the house won’t cool, the cause is usually something we can find and fix in one visit: a failed capacitor, a frozen evaporator coil, a clogged condensate drain, low refrigerant from a leak, or a worn contactor. Our technicians test the system step by step, explain what they found, and give you the price before any work starts. The most common parts ride on the truck. We repair central air conditioners, heat pumps and ductless mini-splits on all major brands. Learn more about our air conditioner repair service.

No heat, short cycling, or a furnace that lights and then shuts off. We repair gas, oil and electric furnaces, checking ignition, flame sensors, blower motors, limit switches and venting until we find the real cause. In Warminster’s older homes we also check the flue and chimney connection, because a blocked or corroded vent can shut a furnace down or push combustion gases back into the house. If you smell gas, leave the house and call your gas utility first. See our furnace repair service or furnace repair in Warminster.

We repair ducted heat pumps and dual-fuel systems in homes and townhomes across Warminster. Most winter calls are the same handful of problems: an outdoor unit that stays iced over, a system stuck on emergency (auxiliary) heat, a reversing valve that won’t switch, and weak airflow from a dirty coil or a failing blower. On dual-fuel systems we also make sure the switchover point between the heat pump and the gas furnace is set right, which has a big effect on your winter bills. Read more about heat pump repair.

When a furnace or air conditioner is more than 15 years old, or a repair would cost about a third of a new system, replacement usually makes more sense. We size new equipment to your home based on its square footage, insulation, windows and how well the old system kept up, then handle removal, installation, permits and startup. Many Warminster homes were built in the 1950s and 60s, so we check the existing ductwork, line set and venting before quoting, so the new system fits the house it’s going into.

Some older Warminster homes still heat with hot water or steam boilers. We repair gas and oil boilers, including pilots and thermocouples, burners, circulator pumps, zone valves, expansion tanks, pressure-relief valves and automatic water feeders. We also check the near-boiler piping, where old steel and brass joints often start to weep with age. When a boiler is near the end of its life, the repair cost decides, not its age: if one repair costs about half the price of a new boiler, we show you both options. See our boiler repair service.

We work on gas, electric, power-vented and tankless water heaters. We replace failed gas valves, thermocouples and elements, and replace leaking tanks, often the same day. When a tank fails, we also check the expansion tank and the water pressure coming into the house, because high pressure without a pressure-reducing valve shortens the life of the new heater. See water heater repair and water heater replacement.

No heat in January or no cooling in July gets priority. We offer same-day emergency HVAC service in Warminster with fast response any time, and our Willow Grove shop is right next door, so the drive is short. Call 215-366-1001 and tell us what’s happening. If you smell gas or a carbon monoxide alarm goes off, leave the house and call your gas utility or 911 first. More on our emergency HVAC services.

New gas lines for ranges, dryers, generators and furnace conversions, plus leak testing and repair on black iron and CSST piping. We pull the permits and schedule the inspections. If you suspect a leak, leave the house and call your gas utility first, then call us to repair the line. Learn more about our gas line services.

Ductless mini-splits are a good fit for additions, finished basements, sunrooms and older homes without ductwork. We install single and multi-zone systems and repair wall, ceiling and floor units on all major brands, including deep cleaning of the coil and blower wheel when buildup cuts airflow. See mini-split repair.
