We answer the phone
A real dispatcher (or our AI assistant Amy after hours) picks up, asks the right questions and gets a technician moving.
Repair first, replace when it's right
If a repair makes sense, we say so. If your system is at the end of its life, we show you the numbers side by side.
Cold-climate heat pump know-how
Sizing and placing heat pumps for Maine winters — so they keep heating at single-digit temperatures.
Residential and commercial
From a Cape in Gorham to a restaurant walk-in on Commercial Street, same standards.

A Maine HVAC calendar

Furnace, boiler and heat pump tune-up before the first hard freeze. Best time to book — no waiting.

No-heat calls, frozen condensate lines and ice on outdoor units. We run 24/7.
Spring (Apr–May)
Heat pump and AC check, filter change, clear the outdoor unit after the plow season.
Summer (Jun–Aug)
Cooling repairs, new mini-splits and commercial refrigeration under peak load.
