What Is Included in a Typical AC Tune Up Service?

A typical AC tune-up service from Paul The Plumber includes a full system inspection, targeted cleaning, precise adjustments, and performance testing to keep your cooling safe and efficient. Most visits focus on airflow, electrical safety, and refrigerant charge because small shifts there cause the biggest comfort and energy losses. Our licensed, background-checked technicians routinely service Seacoast homes, including the New Castle area. Repairs we perform are backed by a 2-year parts and labor warranty, extendable to 3 years for club members under Paul’s Promise.

What we check and do during an AC tune-up:

• Clean coils, replace or clean air filters, and clear the condensate drain for proper airflow and drainage.
• Inspect and tighten electrical connections, measure volts/amps, and test safety components.
• Verify refrigerant levels, test start-up performance, and set proper blower speed.
• Calibrate the thermostat, inspect the evaporator, and perform a visual duct check.

Always shut off power at the disconnect before opening any HVAC panels.
