Licensed technicians. Same-day service available in Princeton and across Mercer County.
Princeton's large older homes with original duct systems and its newer construction along the Route 1 corridor represent two distinct HVAC service profiles. Older homes frequently need capacitor replacements and refrigerant service on aging central AC systems, while newer builds typically have multi-zone or mini-split setups. We serve all residential addresses in Princeton Borough and Princeton Township.

Possibly, but inefficiency is also caused by dirty coils, a weak capacitor, or restricted airflow. We measure system performance before adding refrigerant to avoid overcharging.
Annual pre-season maintenance is recommended — spring for cooling, fall for heating. This catches capacitor wear and dirty coils before they cause a mid-summer failure.
