AC Tune Up Cost: Average Prices & Cost Factors

An AC tune-up is a seasonal maintenance visit in which a technician inspects, cleans, and tests the cooling system. It usually happens in spring, before the cooling season starts. The price depends on the type of system, whether the visit includes extra cleaning, and whether you pay per visit or through a maintenance plan.

Prices here come from This Old House and two other guides, with a check date of Oct 11, 2026. The tables show costs by system type, add-on services, and annual plans.

Different systems need different amounts of work. A portable or window unit is simple, while a central, geothermal, or mini-split system has more components to check.

Mini-split and geothermal systems sit at the high end because they involve more specialized equipment. A central air system, which is the most common type in American homes, falls in the middle of the range.

Services vary by company, so ask for a checklist. A visit commonly covers checking the refrigerant level, inspecting electrical connections, testing the thermostat, cleaning or replacing the air filter, checking the condensate drain, and inspecting the outdoor unit and coils. Some companies include coil cleaning in the base price, while others charge extra.

A tune-up is an inspection and cleaning. It does not include repairs. If the technician finds a worn part, a refrigerant leak, or a failing capacitor, you will get a separate quote.

Some jobs fall outside a basic tune-up and are priced separately.

A clogged drain line can cause water to back up and shut the system off, and dirty coils make the system work harder. A technician may recommend either one during a routine visit. Ask what the add-on includes and whether it is needed this year.

Many companies bundle heating and cooling checks into a single yearly visit.

A combined visit costs more than an AC-only tune-up but covers the furnace or heat pump as well. If you have both systems, it is often more convenient to schedule them together.

Some HVAC companies sell yearly agreements that include one or two visits.

Plans often add perks such as priority scheduling, discounts on repairs, or waived service call fees. They make sense if you would book the visits anyway. Read what the contract covers and whether the visits are included in the price.

• System type. Window, central, packaged, geothermal, and mini-split systems each require different work.
• System size and age. Larger or older systems can take longer to check.
• Add-ons. Drain line cleaning and coil cleaning raise the total.
• Location. Labor rates vary by region and by company.
• Season. Spring and early summer are busy, and some companies charge more or have long waits.
• Service plan. Members may pay less per visit.

Guides disagree because they define a tune-up differently. One may count a basic inspection, another a more thorough visit with cleaning.

All three sources above land within a similar range. A manufacturer's guide, a home improvement publisher, and a cost data site each list a floor near the low end of the range and a ceiling near the high end. Use these as a reasonableness check and ask for a flat price before the technician starts.

Regular maintenance can help the system run as designed and may catch small problems before they become breakdowns. Some manufacturers also require proof of regular maintenance to keep a warranty valid, so check your warranty terms. Whether it is worth the price for you depends on the age of the system and how well you keep up with filter changes and other basics.

Homeowners can handle part of the routine. Changing the air filter, clearing debris and vegetation from around the outdoor unit, and keeping the drain accessible are all simple tasks. A professional is needed for refrigerant checks, electrical testing, and coil cleaning. Handling refrigerant requires certification, so leave that to a licensed technician.

• What does the tune-up include, and is there a written checklist?
• Is coil or drain line cleaning included or priced separately?
• Is there a service call or trip fee on top of the visit price?
• Is there a maintenance plan, and what does it cover?
• Will you get a report of the findings?
