The national average cost of servicing your AC system ranges from around $170-$752, and most people pay around $354 according to Thumbtack data. However, prices can be much higher, depending on your project. For example, during a service call, your HVAC pro may discover that your system require new replacement parts. When you include the cost of new parts and labor, the total cost can be several hundred dollars — sometimes even thousands of dollars.
Average AC service costs
| National average cost range | $170-$752 |
|---|---|
| Low-end cost | $56 |
| High-end cost | $2,190 |
Ultimately, what you pay depends on whether the technician performs a simple tune-up and cleaning, or if they discover any larger issues with your air conditioner that they need to repair.
Routine maintenance prolongs the life of window units, evaporator coolers (also known as swamp coolers), split AC systems, and central air conditioning systems. It also ultimately saves money on energy bills and keeps the home cooler — a triple win.
Before you hire a technician to service your AC, get an estimate on air conditioning service and maintenance costs.
What impacts AC service costs?
The total price you pay for AC service and maintenance will depend on the flat rate or hourly fee your contractor normally charges and, if there is a problem, what it costs to repair that specific issue with your air conditioning.
HVAC technician rates
For routine maintenance, most AC service technicians charge a fixed price of $170-$752. Some HVAC professionals charge an hourly rate for service work. Expect to pay $65 an hour on average. The hourly rate may apply to their travel to and from the job location, or it may solely apply to work done on-site (in which case, some contractors charge a separate travel fee to cover transportation costs).
Below are some example rates several HVAC technicians charge for AC service calls, and what their services include:

- New customer tuneup special: $59
- Standard air conditioning system tuneup: $89
Common repair costs
If your air conditioner needs repairs, the national average for labor and parts is $300. However, the actual amount you'll pay to repair your air conditioner depends on the type of repair it needs:
| Repair | National average cost |
|---|---|
| Add refrigerant | HCFC-22 (R22) refrigerant: $349 for 3 pounds R410A refrigerant: $199 for 3 pounds. Note: HCFC-22 refrigerant production will stop in 2020. Costs may increase as supply decreases. You must use the refrigerant specified by the manufacturer. |
| Repair refrigerant leak | $225 to $1,000 |
| Clearing clogged condenser line | $150 |
| Replace a thermostat | $90 to $120 |
| Replace the capacitor | $100 to $400 |
| Install new circuit board | $120 to $600 |
| Install new condenser fan | $400 to $500 |
| Replace evaporator coil | $710 |
| Replace the compressor | $1,000 or more |
| Replace ductwork | $35 to $55 per linear foot to install, including labor and materials or $150 to $250 per duct run (typical homes have 6 to 10 runs) |
Replacing your air conditioning
Expect to pay $4,000 to $12,000 on average to install a new whole-house HVAC system. To install new ductless air conditioning, estimate $1,800 to $7,000.
In some cases, it's more cost-effective to replace your AC system. If repair costs exceed $500, the unit is more than 10 years old, or it uses HCFC-22 refrigerant which will stop being produced in 2020, consider replacing instead of repairing your air conditioning.
What's included in a routine AC service call?
AC service fees will cover a standard checklist to evaluate your air conditioner's performance and conduct maintenance to prevent larger problems. Depending on the type of HVAC system you have, a technician will typically go through this AC service call checklist during a regular tune-up:
- Turn on the system to check the accuracy of the thermostat.
- Conduct a diagnostic test on your unit's electrical terminals.
- Measure amp draw and electrical current.
- Check and tighten electrical connections.
- Run through the electrical control sequence, ensuring the cooling and heating system can't operate at the same time.
- Measure airflow through the evaporator coil.
- Inspect the coil fins. It's common for these to become bent over time. Using a fine comb, the technician will brush them back into shape.
- Clean outdoor evaporator and condenser coils with specialty cleaner (if you have an outdoor unit).
- Clear any debris from the fan, condenser, and compressor in dual split systems or around window units.
- Inspect window seals around window units.
- Inspect ductwork in central AC systems and fix loose seals.
- Inspect and flush drain lines if necessary.
- Check for adequate refrigerant level and test for refrigerant leaks.
- Check blower wheel and blades for proper air flow.
- Lubricate the motor and other moving parts.
- Inspect motor belts and pulleys for wear and tightness.
- Replace or clean the air filter.
Common air conditioner problems
During the tune-up, there are three common problems your HVAC professional might uncover:
- It blows hot air. If your air conditioning is on but only warm air blows from the vents, your system may need a refrigerant recharge or there may be a leak in the line.
- It won't turn on or off. First, check to make your thermostat works. It may need new batteries. If that's not the problem, there could be a failure somewhere in the electrical connection.
- The AC unit is frozen. Several things may be going on. If the AC doesn't have enough refrigerant, the coils can become too cold. If the fan is damaged, it can prevent air from circulating.
How can you save money on air conditioning service calls?
Most air conditioning systems last 15 years on average (window units typically last about 10-12). Regular air conditioner maintenance and tune-ups can help your unit reach its full lifespan.
Regular cleaning and filter changes
Between service calls from an HVAC professional, make sure you're cleaning or replacing the AC system's air filter. Dirty filters can collect debris, block airflow, and clog the evaporator coil, which absorbs your home's heat. If you use your AC frequently, do this cleaning task at least every month. If you have multiple pets, severe allergies, or experience high levels of dust (like during a home remodel), change it once every three weeks.
According to the Department of Energy, the average household spends 6% of its energy costs on home cooling, but this maintenance task can reduce your air conditioner's energy consumption by 5 to 15%.
Ask about discounts
Be sure to ask about new customer rates. Getting your system serviced in the off-season (so, not in the middle of a summer heat wave), when HVAC companies are looking for business, can also save you some money.
Consider a long-term contract with your HVAC professional
Most HVAC service providers offer discounts for multi-season or long-term contracts, which usually bundles your furnace maintenance and air conditioning maintenance together. The contractor will inspect the furnace in the early fall, before the start of the winter season, to make sure your system heats adequately. Then, before the start of summer, they will make sure your AC runs smoothly and efficiently, so you stay cool all summer long.
Another perk of signing a long-term contract is that if something does go wrong unexpectedly, most HVAC service providers ensure that contract clients get priority attention, without the added emergency cost. During a heat wave, that can mean the difference between languishing for days or instant relief.
How to find a good HVAC technician
You can't just hire anybody to service your AC — you need to hire someone who is qualified, reputable and affordable. Take these steps to ensure you hire the best pro to service your AC:
