AC Repair in Northern Virginia
When your air conditioner stops cooling on a hot Virginia day, you do not need a sales pitch — you need a technician who shows up, finds the real problem, and fixes it. 911Air-Care provides AC repair for homeowners across Northern Virginia, from our home base in Herndon to Fairfax, Reston, Arlington, Alexandria and beyond. We explain what we find in plain language, show you your options, and complete most repairs the same day.
Signs Your AC Needs Repair
- Warm air coming from the vents, or rooms that never reach the set temperature
- Weak airflow, or one room much hotter than the rest of the house
- Ice on the refrigerant lines or water leaking around the indoor unit
- Strange noises — grinding, squealing, banging, or buzzing
- The system turns on and off every few minutes, or runs all day without stopping
- A sudden rise in your electric bill, or a musty smell when the AC runs
Some of these problems start small. Catching them early usually means a simpler, less expensive repair — and no breakdown in the middle of a heat wave.
How Our AC Repair Works
- Step 1 — Book in minutes. Call us or book online and pick a time that works for you. For emergencies, we answer 24/7.
- Step 2 — Full diagnosis. Our technician checks the whole system — not just the part that failed — so the same problem does not come back next month.
- Step 3 — Clear options, up front. We explain the problem, your repair options, and the cost of each one before any work begins. No surprises.
- Step 4 — Repair and test. We complete the repair, test cooling across the house, and make sure everything runs the way it should before we leave.
All Major Brands Serviced
Our team repairs and services all major air conditioning brands, including Carrier, Bryant, Goodman, York, Trane, Lennox and Rheem — central air conditioners, heat pumps and ductless mini-split systems.
Repair or Replace?
If your system is older, needs repairs often, or struggles to cool the house evenly, a replacement can sometimes make more sense than another repair. We will tell you honestly which way we would go if it were our own home — and if a repair will keep your AC running well, that is what we will recommend. Estimates for new systems are free.
AC Repair FAQs
How fast can you come out?
We offer same-day appointments across most of Northern Virginia, and we are on call 24/7 for emergencies.
Do you repair my brand of AC?
Almost certainly, yes. We service all major brands, including older systems.
Will I know the cost before you start?
Yes. After the diagnosis, we explain your options and the cost of each one. Work only begins when you approve it.
My AC is running but the house is still hot. What should I check first?
Check that the thermostat is set to “cool,” replace a dirty filter, and make sure vents are open. If it is still not cooling, call us — it may be a refrigerant, airflow or electrical issue that needs a technician.
