How much does AC tune-up cost?
An AC tune-up is a yearly checkup for your central air. A tech cleans the outdoor coil, checks refrigerant pressures and electrical parts, and clears the drain line. It takes about an hour, so the price is mostly the visit and the tech's time. Booking in spring, before the first heat wave, is usually easiest.

What's usually included
- Outdoor condenser coil rinsed and the area around it checked for debris
- Refrigerant pressures and temperatures measured
- Capacitor, contactor and wiring checked for wear
- Condensate drain line flushed so it does not back up
- Air filter checked, and replaced if you have one on hand
- Thermostat tested to make sure the system starts and stops correctly
What changes the price
- Number of systems. Homes with an upstairs and downstairs unit need two tune-ups.
- Timing. Spring visits are easier to book. Peak summer and after-hours calls cost more.
- Condition. A very dirty coil or a clogged drain line takes extra time.
- Parts. A worn capacitor or contactor found during the visit is priced on top.
Do it yourself or hire a pro?
You can do the basics yourself: change the filter, keep plants and leaves a couple of feet away from the outdoor unit, and gently hose off the coil with the power off. Checking refrigerant and testing electrical parts needs gauges, meters and training, so leave that part to a tech.
Common questions
Is an AC tune-up really worth it?
A yearly check can catch small problems, like a weak capacitor or a clogged drain line, before they cause a breakdown on a hot day. Many equipment warranties also require regular maintenance, so check yours.
How long does an AC tune-up take?
Most take about an hour for one system. A very dirty unit or a problem found during the visit can make it longer.
Should a tune-up include adding refrigerant?
No. A healthy system does not use up refrigerant. If the tech says it is low, there is a leak, and adding refrigerant is a separate charge.
