Short cycling is a common issue here, often caused by an oversized unit, a dirty air filter restricting airflow, or a faulty thermostat. It puts excessive strain on your system and drives up energy costs. Our technicians will diagnose the root cause, whether it's a simple fix like cleaning the coils or a more complex refrigerant issue, to restore proper operation and protect your equipment.

A failing reversing valve, which switches your system between heating and cooling, often shows as the system getting stuck in one mode, providing lukewarm air, or making a distinct hissing noise. Given our climate's demands on heat pumps, this part can wear. We'll test the valve's operation and electrical controls to determine if a repair or replacement is needed for consistent comfort.

Proactive maintenance is key. We recommend biannual tune-ups—once before summer and once before winter. This includes cleaning components, checking refrigerant levels, testing electrical connections, and ensuring the reversing valve cycles properly. Regular maintenance by our team helps catch small issues before they become major repairs, improving efficiency and extending the life of your system.
