HVAC in South Portland, ME
J&R Mechanical Services provides HVAC service in South Portland, Maine, part of our Cumberland County service area. We repair, replace, and maintain heat pumps, furnaces, boilers, and air conditioning, with a crew that also handles the plumbing side of every HVAC job.
How a Heat Pump Works
- Outdoor unit — fan and compressor extract heat from outside air
- Reversing valve — switches the system between heating and cooling
- Line set — carries hot, high-pressure refrigerant indoors
- Indoor coil — releases heat into the airstream
- Warm air — the blower delivers it to the room
HVAC for South Portland Homes
We service every kind of heating system a home might have. Our heat pump and mini-split team installs and repairs cold-climate systems. For forced-air homes we handle furnace repair and high-efficiency furnace replacement. For hydronic homes — baseboard, radiators, and radiant floors — we provide boiler repair, annual cleanings, and boiler installation for oil, propane, and natural gas systems.
How We Handle HVAC Calls
Cooling matters too. We install central and ductless air conditioning, and for most homes we recommend a heat pump that does both jobs — cooling in summer and heating in winter. Because we also hold plumbing capabilities, the gas piping and condensate work that come with new equipment can happen under one crew.

- Refrigerant work is done under EPA Section 608 certification, and the new circuit for the outdoor unit is permitted before it is wired.
