Keep Your System Running When You Need It

Heat pump service and maintenance for residential and commercial properties in Lincoln, Maine.

Your heat pump runs almost year-round in Lincoln, Maine, switching between heating in the winter and cooling in the summer without a break. That constant use means filters clog, coils collect dust and pollen, and refrigerant levels can drift if there is a slow leak. Regular service keeps the system running at full capacity and prevents small issues from turning into expensive repairs during a cold snap or heat wave.

Dow Industries provides routine maintenance visits that include cleaning indoor and outdoor coils, checking refrigerant charge, inspecting electrical connections, and testing thermostat response. If your system is not heating or cooling as it should, diagnostic work identifies whether the issue is a failed component, a control board error, or something as simple as a tripped breaker or dirty filter.

If your heat pump is overdue for service or you notice reduced airflow or strange sounds, reach out to schedule a maintenance visit in Lincoln.

How Maintenance Extends Equipment Life and Performance

A maintenance visit in Lincoln starts with a visual inspection of the outdoor unit, checking for debris buildup, damaged fins, or ice formation during colder months. The technician cleans the coils, checks the condensate drain, and inspects the fan motor and compressor for signs of wear or unusual noise.

After the service is completed, you will notice better airflow from the indoor units, more consistent temperatures across rooms, and quieter operation. Your system will cycle on and off less frequently because it does not have to work as hard to reach the set temperature.

If refrigerant levels are low, the technician adds the correct type and amount after locating and sealing the leak. Electrical connections are tightened, and the thermostat is tested to confirm it communicates properly with the heat pump. Seasonal maintenance before winter and summer helps the system handle peak loads without failing when you need it most.

You Probably Have a Few Questions

Most property owners in Lincoln ask about timing, costs, and what happens if something breaks between scheduled visits. Here are answers to the questions that come up most often.

How often should I schedule heat pump maintenance?
You should schedule service twice a year, once before the heating season and once before cooling season. Systems that run constantly or serve commercial properties may benefit from quarterly visits.
What happens if my heat pump stops working in the middle of winter?
Dow Industries provides repair services for heat pumps that fail outside of scheduled maintenance. The technician will diagnose the issue, explain what needs to be fixed, and complete the repair as quickly as parts and conditions allow.
Can I clean the outdoor unit myself?
You can remove leaves and debris from around the unit and gently rinse the exterior coils with a garden hose, but avoid using high pressure or bending the fins. Internal cleaning and refrigerant work should be handled by a trained technician.
Why is my heat pump running but not heating the space?
Low refrigerant, a dirty coil, a failing compressor, or incorrect thermostat settings can all cause this issue. A technician will test each component to pinpoint the cause and restore heating.
What will regular maintenance cost?
Service visit costs vary based on system type and what work is needed, but routine maintenance is less expensive than emergency repairs. Dow Industries provides pricing when you schedule your visit in Lincoln.
