HVAC Repair in Portland — What to Expect

When your heating or cooling system stops working, you need a licensed technician on-site fast — not a call center. Southern Maine Mechanical provides expert HVAC repair across greater Portland and all of southern Maine, with honest diagnostics, upfront pricing, and repairs done right the first time.

We serve Portland and nearby South Portland, Cape Elizabeth, Falmouth — typically reaching Portland customers same-day or next-day for standard service calls, and within two hours for heating and cooling emergencies.

Same-Day HVAC Repair Available Across Southern Maine

We know a broken HVAC system can't wait. Whether your furnace quit on a January night in Windham or your AC gave out on the hottest day in Kennebunk, our technicians are dispatched fast. We serve Portland, South Portland, Scarborough, Falmouth, Cape Elizabeth, Westbrook, Gorham, and 25 more towns across York and Cumberland counties — and we aim to be on-site the same day you call.

We Repair All HVAC Makes and Models

Our technicians are trained and experienced on every major system type: central air, mini-splits, heat pumps, gas and oil furnaces, boilers, and hybrid systems. We carry parts for Mitsubishi Electric, Carrier, Lennox, Trane, Daikin, Bosch, Samsung, Weil-McLain, Burnham, and most other brands. If we can't fix it same day, we'll tell you honestly — and we'll tell you why.

Common HVAC Problems We Fix Every Day

The most frequent HVAC repair calls we receive are: no heat or no cooling, strange noises (banging, squealing, rattling), short cycling, frozen evaporator coils, refrigerant leaks, ignition failures, blower motor failures, thermostat issues, and dirty or clogged filters causing system shutdowns. No matter the symptom, we diagnose the root cause — not just the immediate failure.

Serving Portland and Cumberland County

Southern Maine Mechanical is locally based in Gorham, ME — right in the heart of Cumberland County. When a Portland homeowner calls us, they're reaching a local contractor who knows the area, not a regional chain dispatching whoever is closest.
