Portland Air Conditioning - Scarborough's Trusted HVAC Repair

In our Maine climate, heat pumps often freeze due to low refrigerant levels, dirty coils, or a malfunctioning defrost cycle. Our technicians first safely thaw the unit, then perform a thorough diagnostic to pinpoint the exact cause—whether it's a leak, a sensor issue, or airflow blockage. We'll repair the root problem to prevent recurrence and ensure your system operates efficiently through the next cold snap.

For most Scarborough homes, we recommend checking your filter monthly and replacing it every 1-3 months, especially during peak heating and cooling seasons. Pets, coastal humidity, and local pollen can clog filters faster. A clogged filter restricts airflow, making your system work harder, which can lead to frozen coils or premature failure. We can assess your home's specific needs during a maintenance visit.

We recommend a bi-annual professional tune-up—once in the fall for heating and once in the spring for cooling. This includes cleaning coils and components, checking refrigerant levels, testing the defrost cycle on heat pumps, inspecting electrical connections, and ensuring proper airflow. This proactive service is the best defense against the frozen components and efficiency losses common in our area, saving you from emergency repairs.
