Refrigerant recharge
An AC refrigerant recharge costs $100 to $320 for R-410A refrigerant or $180 to $600 for older AC units using R-22 Freon. Annual AC tune-ups and maintenance plans typically do not include a refrigerant refill.
AC units never need more refrigerant unless there is a leak or the refill is part of a repair.
AC leak check cost
An AC leak check costs $100 to $330. Finding and repairing an AC leak costs $200 to $1,500, depending on the location, severity, leak test method, and whether the repairs require any replacement parts or refrigerant.
AC cleaning cost
AC cleaning costs $100 to $400, depending on the coil type and location. Evaporator coils typically cost more to clean than condenser coils because they are more difficult to access.
| Service | Average cost |
|---|---|
| Condenser coil cleaning | $75 – $230 |
| Evaporator / air handler coil cleaning | $100 – $400 |
| Blower wheel cleaning | $125 – $250 |
| Acid wash AC coils | $300 – $350 |
AC inspection cost
An HVAC inspection costs $150 to $500, depending on the system size and type. An HVAC inspection is recommended when buying a new home to confirm the heating and cooling systems function properly and safely.
Annual AC maintenance cost
HVAC maintenance costs $120 to $360 per year, depending on the system type and services included. Most maintenance plans include:
Air filter cleaning or replacement
AC tune-ups twice per year
Same-day or priority repair service
Lower rates for emergency service calls
Discounts of 5% to 15% on repairs or parts
An annual AC maintenance plan is worth the investment if the system is no longer under warranty or if the manufacturer requires yearly service for the warranty to remain valid. Regular maintenance may prevent the need for costly repairs.
Split AC maintenance cost
Ductless mini-split AC maintenance costs $100 to $400 per year, depending on the system size and number of zones. Most mini-split systems require annual service for the manufacturer's warranty to remain valid.

AC service call cost
An AC service call costs $75 to $200 on average. Service call rates cover only the HVAC technician's visit to diagnose the problem and don't include repairs, parts, or refrigerant. However, most AC companies apply this fee to the repair costs.
| Factor | Average cost |
|---|---|
| Service call / diagnostic fee | $75 – $200 |
| Standard hourly rate | $75 – $150 |
| Emergency hourly rate | $160 – $250 |
Cost to level an AC unit
Leveling an AC unit costs $100 to $200 if the condenser already has a concrete or composite pad beneath it or $200 to $300 if a new pad is required. The condenser must be level to ensure the compressor is properly lubricated and the refrigerant flows evenly through the coils.
Take care when leveling an AC condenser yourself. Shifting the condenser can easily damage the line set, causing leaks or other expensive repairs.
AC check-up cost factors
The following factors impact the AC check-up cost:
AC system size – A tune-up costs more for larger systems with multiple condensers.
Accessibility – Labor costs increase for AC units in difficult-to-access attics and crawlspaces.
Maintenance frequency – If the system hasn't been inspected in a few years, a tune-up may cost more because the extra dirt build-up takes longer to clean.
Season – AC companies may offer discounts during the off-season.
Home size and ductwork – Larger homes have more extensive ductwork, increasing labor time.
Repairs needed – Repairs and replacement parts cost extra if the AC technician discovers a problem during the tune-up.

AC tune-up service FAQs
What is an AC tune-up?
An AC tune-up is a preventative maintenance service to clean the system, change the filters, flush the drain line, and examine the indoor and outdoor components for potential problems before they require costly repairs. An annual tune-up ensures the AC unit runs at peak efficiency throughout the year.
How often should AC be serviced?
An air conditioner should be serviced at least once per year to ensure the system is clean and running smoothly. Some manufacturers require annual maintenance for the warranty to remain valid.
Consider a semi-annual tune-up in the spring and fall for HVAC systems that heat and cool.
What are the signs I need an AC tune-up?
Signs your AC system needs a tune-up include:
Weak airflow from the vents
Air conditioner runs often but doesn't cool the home
Higher than normal humidity in the home
System cycles on and off frequently
Unusual noises coming from the system
Stale or musty smell from the vents
Increased utility bills
How long does an AC tune-up take?
An AC tune-up takes 1 hour on average, not including time for repairs or adding refrigerant.
Do you tip an AC service repair tech?
Tipping an AC repair tech is optional but most appreciate the gesture. Standard tipping rates for HVAC technicians are $20 to $25 if the quality of their work exceeds your expectations.
What happens if an AC is not serviced?
An AC system is more likely to break down if not serviced regularly and may require costly repairs. Not following an annual maintenance plan may also void the manufacturer's warranty.
Getting AC service quotes
Before hiring an AC repair service near you, be sure to:
Get quotes from at least three HVAC companies to compare.
Look for a NATE-certified technician with experience installing and repairing air conditioners.
Confirm the technician is EPA Section 608 certified to handle refrigerants.
Read their reviews on HomeGuide and Google
Select companies that are insured, bonded, and have been in business for 5+ years.
Ask for a checklist of items the AC tech will inspect as part of the tune-up.
Beware of companies that offer low-cost AC tune-ups. They often charge more than average for repairs or attempt to pressure you into buying a new AC system.
Get a detailed estimate, contract, and warranty in writing before the work begins.
Never pay in full before the project starts. Follow a payment plan instead for work completed.
