How much does AC repair cost in Northern Virginia?
Pricing comes down to which part has failed, how accessible your system is, and your AC’s age and brand. Here are the typical 2026 price ranges we see across Sterling, Ashburn, and the rest of Northern Virginia.

| AC tune-up | $99-$179 |

What are the most common AC repairs and what do they cost?
Capacitor or contactor failure
The capacitor and contactor are small electrical parts that start and run your AC. They are also among the most common failures in our hot, humid summers. A capacitor runs $199-$400 and a contactor runs $200-$450. These are usually quick fixes that get your system cooling again the same day.
Low refrigerant and recharges
If your AC is blowing warm air, it may be low on refrigerant. R-410A costs $75-$110 per pound, and a typical 2-4 pound recharge totals about $250-$450. Important: low refrigerant almost always means a leak, so simply “topping off” without finding the leak is a temporary fix. A proper repair locates and seals the leak first.
Condenser fan motor
The fan motor in your outdoor unit pushes heat out of your home. When it fails, your AC can overheat and shut down. Replacement typically runs $400-$750 depending on the motor and your unit.
Compressor replacement
The compressor is the heart of your AC, and replacing one is the most expensive common repair at $1,500-$2,800. Because the cost is so high, a compressor failure is often the moment homeowners weigh replacing the whole system instead.
How much is a diagnostic or service call?
A diagnostic visit starts at $89, and that fee is often waived when you approve the repair. The visit pays for the technician’s time to properly diagnose the issue, so you get an accurate quote instead of guesswork. You will always know the repair price before any work begins.
Should I repair or replace my AC?
A simple rule of thumb for Northern Virginia homeowners:
- Repair if your unit is under 10-12 years old and the repair costs less than about one-third of a new system.
- Consider replacing if your AC is older, faces a major repair like a compressor, or has needed repeated fixes.
- Factor in efficiency. Virginia’s minimum is now 14.3 SEER2, and a newer high-efficiency system can noticeably lower your summer energy bills.
Not sure which way to go? We will give you an honest recommendation. Regular maintenance and tune-ups ($99-$179) also help you avoid surprise breakdowns by catching small issues early.
How can I lower the cost of AC repair?
- Don’t delay. A small problem like a weak capacitor can cascade into a compressor failure if ignored.
- Bundle a tune-up. Seasonal maintenance keeps your system efficient and extends its life.
- Check for current offers. See our specials for seasonal savings.
- Finance larger work (coming soon). If a repair turns into a replacement, flexible monthly financing is coming soon to help spread the cost. Explore financing options here.
