Do this now: no heat or no cooling in DC

1. Smell gas or hear a carbon monoxide alarm? Get everyone outside and call 911 or the gas utility from there. CPSC says not to go back in until responders say it is safe.
2. Check the thermostat mode and setting, then the breaker for the furnace or air handler and the outdoor unit.
3. Look at the air filter; a clogged filter can choke airflow.
4. Losing heat in a freeze: open sink cabinet doors and let cold water drip from faucets on outside walls, the American Red Cross says.
5. Note any error code or noise to tell the technician.

Is it an emergency? DC's 40 hot days and 60 freezing nights

Washington averages 40.0 days a year at or above 90 F and 60.1 nights at or below 32 F at Reagan National, NOAA's 1991 to 2020 normals show, so a failed system is urgent in both seasons. Call now for no heat in a freeze, no cooling with someone elderly or sick at home during a hot spell, a gas smell or a CO alarm. A noisy unit that still heats or cools can wait for a daytime visit; after-hours rates are in emergency HVAC repair.
