AC Not Turning On in Washington, DC

AC not turning on in Washington, DC is a control problem more often than a mechanical one. The thermostat calls for cooling, nothing happens, and the house heats up. Our crew starts on the low voltage side because that is where the answer usually is.

The 24 volt control circuit runs from a transformer in the air handler or furnace to the thermostat and out to the condenser. A blown 3 amp fuse on the control board kills the whole thing. So does a float switch in the drain pan that tripped because the condensate line backed up. That safety switch is doing its job, and the real fix is clearing the drain line.

Other causes on our list: dead thermostat batteries, a loose wire at the thermostat base, a tripped breaker at the panel, a pulled disconnect at the outdoor unit and a failed transformer. On older systems we sometimes find a rodent has chewed the thermostat cable where it runs along the foundation.

We test each point with a meter and show you the reading. Call (866) 703-1217 when your AC not turning on leaves you guessing.

Central AC Repair FAQs

Common questions about central AC repair

Questions we hear about AC Not Turning On in Washington, DC.

Talk to our crew
Is it worth repairing an older R-22 system?
Sometimes. R-22 has not been produced or imported in the US since 2020, so any recharge uses reclaimed refrigerant at a high price. A small electrical repair on an R-22 unit can still make sense. A major leak or a failed compressor on one usually does not. We'll give you both numbers.
Can you just add refrigerant to my AC?
We can, but it rarely makes sense on its own. A central AC system is sealed, so low refrigerant means a leak. Topping it off without fixing the leak means the charge leaks out again. We find the leak, repair it and weigh in the correct charge.
How long does a central AC system usually last?
Many central air systems run 12 to 15 years with regular maintenance. Units near the coast, where salt air corrodes coils, and units in very long cooling seasons often wear out sooner. Age alone is not a reason to replace, but it factors into repair decisions.
Why is water leaking from my indoor unit?
Most of the time it is a clogged condensate drain line, a cracked or rusted drain pan, or a frozen coil that is melting. Turn the system off to limit water damage and call us. We clear the line, check the pan and test the safety float switch.
Do you work on heat pumps and furnaces too?
Our focus is central air conditioning: split systems and packaged units, the outdoor condenser and the indoor coil and air handler. Call (866) 703-1217 and tell us what you have, and we'll let you know if it is a job for our crew.
