Short cycling is a common issue here, often caused by a clogged air filter restricting airflow, a faulty thermostat, or an oversized system. Our technicians will diagnose the root cause, which could be a simple filter change or a more involved repair, to restore efficient and safe operation for your home.

In Bangor's climate, with varying pollen, dust, and heating seasons, we recommend checking your filter monthly and replacing it at least every 90 days. More frequent changes (every 30-60 days) are advised if you have pets or allergies. Regular filter changes are a key part of our maintenance services to improve air quality and prevent strain on your HVAC system.
