An AC tune-up typically costs about $70 to $200 for a standard central air system, and the averages national cost guides report sit around $130. Annual HVAC maintenance plans that bundle a cooling and a heating visit usually run about $150 to $350 a year. The tune-up price covers inspection, cleaning and measurements; repairs, parts and refrigerant are extra.
What matters more than the price is what the technician actually does for it. A good tune-up produces measurements you can see. A cheap one can be a quick look and a sales pitch. This page covers both the cost and how to tell the difference. For the whole-system picture, see our HVAC system maintenance guide.
Typical AC Tune-Up and HVAC Maintenance Prices
| Service | Typical range in cost guides | What drives it |
|---|---|---|
| Central AC tune-up | About $70 to $200 | Region, season, how much cleaning is included |
| Heat pump or full HVAC tune-up | Toward the upper end, or priced per system | Two modes to check, more components |
| Ductless mini-split tune-up | Usually more than a central AC | Number of indoor heads, coil cleaning method |
| Annual maintenance plan (two visits) | About $150 to $350 a year, some higher | Number of systems, perks, included filters |
| Service call or diagnostic fee | About $75 to $200 | Often credited toward a repair |
These ranges come from national cost guides and are typical, not quotes. A plan that costs about the same as two single visits isn't a deal by itself; the value is in the perks and whether you'd book the visits otherwise.
What a Real AC Tune-Up Includes
Most companies list a checklist. The difference between a thorough tune-up and a quick one is whether the technician measures and records numbers. Ask for the readings.
| Task | What the technician should do | What you should get |
|---|---|---|
| Airflow and filter | Check the filter, blower and static pressure | Filter condition, a static pressure reading if they take one |
| Outdoor coil | Rinse or clean the condenser coil, straighten fins, clear debris | Before and after condition |
| Indoor coil and drain | Inspect the evaporator coil, clear the condensate drain and pan, test any float switch | Note on drain condition and coil cleanliness |
| Refrigerant charge | Measure pressures and temperatures, calculate superheat or subcooling | The readings compared with the manufacturer's target |
| Temperature split | Measure supply and return air temperatures | The difference in degrees |
| Electrical | Test the capacitor, inspect the contactor, tighten connections, measure motor amp draw | Capacitor reading against its rating, amp draw |
| Controls | Check thermostat operation and the safety switches | Note on any faults |
| Moving parts | Inspect fan motors and blades, lubricate where the motor has oil ports | Note on motor condition |
Our guide on what a professional AC tune-up includes walks through each check in more detail. Many of the homeowner-level tasks, like clearing the outdoor unit and changing the filter, are in the DIY AC maintenance checklist.
What a tune-up doesn't include
- Replacement parts, such as a capacitor, contactor or fan motor
- Refrigerant, which is billed separately
- Leak detection and leak repair
- Duct cleaning or duct repair
- Chemical coil cleaning beyond the standard rinse, at some companies
What Changes the Cost of an AC Tune-Up
- System type. A heat pump has a reversing valve and defrost controls to check. Mini-splits have one or more indoor heads whose coils and blower wheels may need deep cleaning.
- Scope. A visit that includes full coil cleaning and refrigerant readings takes longer than a visual inspection.
- Access. Attic air handlers, rooftop units and tight crawlspaces add time.
- Season. Spring and fall are easier to book. In a heat wave, contractors are busy with no-cooling calls.
- Age and condition. Older equipment often takes longer to clean and test, and turns up more findings.
- Location. Labor rates vary widely between metro areas and rural regions.
Is an HVAC Maintenance Plan Worth It?
A maintenance plan, also called a service agreement or comfort club, is an annual contract with one company. Most include two visits a year, priority scheduling, and a discount on repairs. Here's a quick way to decide.
| Your situation | Plan makes sense? | Why |
|---|---|---|
| You've skipped tune-ups before | Usually yes | The scheduled reminder is the main value |
| You have a heat pump | Usually yes | It runs year-round and benefits from two visits |
| Two or more systems | Compare carefully | Many plans charge per system |
| One AC, one furnace, and you book visits reliably | Maybe not | Two single visits can cost about the same |
| You plan to move within a year | Often no | Check whether the plan transfers or refunds |
Before you sign, read the fine print:
- What the repair discount applies to. Labor only, parts only, or both? A discount on an inflated price isn't worth much.
- Refrigerant and parts. Almost always excluded.
- Auto-renewal. Many plans renew automatically and bill your card.
- Cancellation. Is there a fee, and is any unused visit refunded?
- Per-system pricing. A house with two air handlers often pays twice.
- Transfer. Whether the plan moves to a new owner if you sell.
A maintenance plan is not a home warranty or insurance. It covers scheduled service, not repair bills. See home warranty HVAC coverage for how those differ.
Maintenance and Your Manufacturer Warranty
Some manufacturers tie warranty coverage to maintenance. Trane's limited warranty for outdoor units, for example, says the product must be maintained by a licensed HVAC service provider and that the company may request written documentation of preventive maintenance. Lennox's limited warranty says failure to maintain the equipment will void the warranty and that proof of prior maintenance may be required. Terms vary by brand and model, so read your own certificate.
Two habits protect you:
- Register the equipment within the manufacturer's deadline after installation. Some brands shorten parts coverage if you miss it.
- Keep every invoice from tune-ups and repairs, with the date and the technician's notes, in one folder or photo album.
Regular service also helps the equipment reach a normal lifespan. Our guide to how long an AC unit lasts covers what wears a system out early.
Red Flags During a Tune-Up
- A refrigerant "top-off" every year. A sealed system doesn't use up refrigerant. Repeated low charge means a leak that should be located; our guide to AC refrigerant leaks explains what finding and fixing one involves.
- No readings, only a verdict. "Your capacitor is weak" should come with a microfarad reading compared with the label rating.
- Pressure to replace a working system after a cheap or free tune-up, without measurements to back it up.
- Chemical treatments or add-ons pushed as urgent on the same visit.
- Very low advertised prices that become a sales visit. A thorough tune-up takes time, often an hour or more for a split system.
Heating Tune-Ups: Furnace and HVAC Visits
If you search for an HVAC tune-up, you'll often see a combined price for cooling and heating. The heating visit covers different parts: burners, flame sensor, igniter, heat exchanger, venting, gas pressure and safety switches. Most plans schedule it in fall. The guide to furnace tune-ups lists what that visit should include. A furnace tune-up is also the right time to check for carbon monoxide risk, which is one more reason not to skip it.
Frequently Asked Questions
How much does an AC tune-up cost?
Most national cost guides put a standard central AC tune-up at roughly $70 to $200, with reported averages around $130. Ductless and multi-zone systems, hard-to-reach equipment and peak-season bookings tend to cost more. Repairs, parts and refrigerant are billed on top.
How often should I get an AC tune-up?
Once a year, ideally in spring before the cooling season starts. If you have a heat pump, which heats and cools, a visit in spring and another in fall is the usual recommendation. Change or check the filter yourself every one to three months in between.
Is an HVAC maintenance plan worth it?
It's worth it if you'd otherwise skip visits, have a heat pump or more than one system, or want priority scheduling in peak season. Most two-visit plans cost roughly $150 to $350 a year, so compare that with the price of two single visits and read what the plan excludes.
Does skipping maintenance void my AC warranty?
It can. Some manufacturers' limited warranties say failure to maintain the equipment can void coverage, and they may ask for proof of maintenance when you file a claim. Read your warranty certificate and keep every service invoice.
Do AC tune-ups include refrigerant?
No. A tune-up includes checking the refrigerant charge, but adding refrigerant is billed separately. An air conditioner is a sealed system, so if it's low on refrigerant there's a leak, and the leak should be found rather than topped off every year.
