Gelinas HVAC: Your Source for Plumbing, HVAC, and Electrical Services

A standby generator is critical during severe weather outages, making regular testing and prompt repair essential so backup power engages when needed. Gelinas HVAC Services has repaired automatic standby generators across Scarborough since 1994, servicing engine controls, fuel delivery, and automatic transfer switches. Working under Maine Electrical License #MS60022397, our licensed electricians follow safety guidelines detailed in CPSC generator safety guidance. Members save on repair service through our Home Advantage Membership. Call (207) 672-2801 to speak with a representative about scheduling a repair visit.

As a local, family-owned business, Greater Portland homeowners trust us to keep their standby power systems ready before severe storms arrive.

What are the most common reasons a standby generator will not start? Dead starter batteries and stale fuel cause most non-start issues, both of which are resolved quickly on site.

Why is my generator running during an outage without powering the house? This indicates a automatic transfer switch failure. The generator engine runs, but the transfer switch fails to engage power.

Do your electricians repair all standby generator brands? Yes, we repair Generac, Kohler, Briggs & Stratton, Cummins, and all major standby generator brands.

How often should a home standby generator be serviced in Maine? Standby generators should be serviced annually in fall. Regular tune-ups ensure starting reliability before winter storms hit.

What does it mean if my generator fails its weekly self-test? A self-test fault alerts you to battery, sensor, or fuel problems while utility power is still active.

Can Gelinas HVAC service my generator during a major power outage? Yes, we respond during outages across Scarborough, though scheduling annual fall maintenance prevents emergency failures.

A standby generator provides vital backup power during severe weather, making prompt repairs essential when starting or transfer switch problems occur. To prevent unexpected starting failures during power outages, schedule routine annual service through our generator service team. If your emergency power demands have grown, explore our options for new generator installation. Because automatic transfer switches connect directly to your service panel, our licensed electricians can perform an electrical panel upgrade to ensure seamless power transfer during utility outages.

A standby generator usually gives clear warning signals when it needs attention:

The engine cranks much longer than usual before starting during weekly self-tests.
The engine runs roughly, misfires, or surges under household loads.
Warning lights are glowing or fault codes display on the controller screen.
The system fails to perform its scheduled weekly exercise cycle.
The unit has gone unserviced for over two years without a professional check.

Leaking fuel or a burning smell during operation requires immediate emergency action. Shut the unit down and call right away. For all other issues, call (207) 672-2801 to book a repair appointment.

Don’t let a failing heating or cooling system disrupt your home’s comfort and safety. Whether you need fast emergency dispatch or routine support, Gelinas HVAC Services delivers prompt, reliable generator repair across Scarborough and Greater Portland. Call our local team today at (207) 672-2801 or request service online to receive a real arrival window and an upfront, transparent estimate.

Common Generator Problems We Solve

During severe coastal Maine ice storms and high-wind power outages, a standby generator is your main line of defense. When a generator fails to start during a blackout in Scarborough, the issue can usually be traced to battery degradation, fuel line clogs, or governor faults. Here are the top generator repairs we perform out in the field.

Standby generators rely on 12-volt starter batteries that degrade after three to four years of outdoor temperature exposure. A dead battery prevents the engine from cranking during a power loss. We load-test starter batteries, replace aging cells with heavy-duty cold-cranking units, and clean corroded battery terminals.

Stagnant fuel or moisture contamination inside gas regulators and carburetors prevents smooth fuel delivery, causing the engine to surge, stall, or refuse to start. We clean or rebuild carburetors, replace inline fuel filters, service automatic fuel solenoid valves, and purge fuel supply lines.

If your generator engine starts running but fails to power your home during an outage, the automatic transfer switch contactor has likely welded or failed to engage. We test ATS control board signals, clean transfer contactors, and replace faulty transfer switch mechanisms so utility power switches seamlessly.
