What we provide
Heating services
SERVICESUnity HVAC delivers reliable warmth with boilers, air handlers, oil systems, natural gas & propane systems, plus heat pumps and mini splits. We ensure efficient, long-lasting heating for your home or business.
Natural Gas & Propane Systems
Natural gas and propane systems provide powerful and efficient heating solutions for homes and businesses,
Fuel Oil Systems (No. 2 Heating Oil)
Fuel oil systems, using No. 2 heating oil, provide dependable and efficient heating for homes and businesses
Air Handlers
Air handlers are the heart of your HVAC system, ensuring efficient airflow and consistent comfort throughout your home or business.
Heating Oil
Oil furnaces and oil boilers
Plenty of homes around Macungie, Emmaus and Alburtis still run on No. 2 heating oil, and a well set up oil system is a good system. We service, repair and replace both kinds — warm-air oil furnaces and hot-water oil boilers — and we carry the burner parts that actually fail on a cold Saturday night.
Thermo Pride oil furnace and new sheet metal. Warm air moves through ducts, which means the same duct system can carry central air.
Energy Kinetics Ascent. Hot water out to baseboard or radiators, on a low-mass boiler that is not left holding heat it never uses.
Natural Gas & Propane
Gas furnaces and gas boilers
On natural gas or propane, or thinking about coming off oil? We install high-efficiency condensing equipment and do the parts a changeover really turns on — gas pipe sized for the load, sidewall venting, condensate run to a drain, and combustion set with an analyser before we pack up.
Weil-McLain condensing boiler with its own zone pumps. Sealed combustion and PVC out through the wall, so an old chimney stops being the limiting factor.
Wall-hung condensing boiler feeding a copper zone manifold. Every loop valved, balanced and labelled so the next person can read it.

Service Area
Sixteen towns, one van, one owner
Unity runs out of Macungie and covers Lehigh County, Bethlehem and Easton in Northampton County, and Quakertown in upper Bucks. Every town below has its own page, because a 1980s electric-heat house in Macungie and a 1900 rowhome in Easton are not the same job, and the fuel your street is on changes the answer more than anything else. Trexlertown, Breinigsville and Fogelsville sit in Upper Macungie Township and are covered on our Upper Macungie page.
