Common Washington HVAC emergencies
Call Now — (844) 582-179524/7 dispatch · Washington-area network
AC out, blowing warm, or iced over
Outdoor unit silent · indoor blower running but warm air · ice on the refrigerant lines · short-cycling on/off. The most common cause is electrical (capacitor, contactor) or refrigerant — both require a technician.
Furnace not igniting or blowing cold
Furnace won't ignite · blowing cold air · short-cycling · burning smell on first startup. If you smell gas, leave the building immediately and call 911 first.
Banging, screaming, or grinding outdoor unit
Loud bangs · metal-on-metal screaming · grinding or rattling from the outdoor unit. Failing fan motors, loose blower wheels, and worn compressor bearings are the usual causes. Turn the system off and call — running through these noises spreads the damage.

Washington's mixed-humid climate & your HVAC
This Zone 4A (Mixed-Humid) climate splits the year between heating and cooling load. Federal SEER2 14.3 (Southeast Region) minimum applies to new AC equipment. Heat pumps that handle both heating and cooling from one outdoor unit are an increasingly popular choice.

HVAC in Washington, DC: local data & sources
Every numerical claim below references a federal, state, or municipal primary source — NOAA climate normals, U.S. Census ACS, the District of Columbia licensing authority, and your local utility's published rebate program.
NOAA NCEI 1991–2020 Normals
Ronald Reagan Washington National Airport (KDCA) is the NOAA reference station for the District. Per the NOAA NCEI U.S. Climate Normals 1991–2020 (station USW00013743), Washington records an annual mean temperature of 59.3°F, approximately 3,769.2 annual heating degree days against 1,737.8 cooling degree days, 41.82 inches of annual precipitation, and 13.7 inches of annual snowfall. The 2.2:1 HDD-to-CDD ratio defines Washington as a classic Zone 4A mixed-humid climate — substantial cold-season heating demand plus humid Atlantic summers that drive meaningful cooling and dehumidification load.
U.S. Census ACS 2022 5-Year
The U.S. Census Bureau ACS 2023 5-year estimates (Tables B25040 and B25035 for Washington city, DC) report 321,556 occupied housing units with a median year built of 1957. Heating-fuel distribution is unusually balanced: 49.2% utility natural gas (158,327 units), 45.6% electricity (146,754 units), and 3,083 fuel-oil-heated units. The near 50/50 gas/electric split is distinctive among major U.S. cities — most cities lean clearly one direction — and reflects the District’s mix of pre-war rowhouses (traditionally gas or oil) and later mid-century apartment buildings (often all-electric).
District of Columbia Licensing Authority
Washington, D.C. is served by Pepco for electricity and Washington Gas for natural gas. Distinctively, DC also operates the DC Sustainable Energy Utility (DCSEU) — a district-mandated efficiency program that administers heat pump rebates, weatherization incentives, and low-income weatherization for DC residents. For current rebate dollar amounts, visit dcseu.com, pepco.com, and washingtongas.com directly. Every HVAC contractor working in DC must hold a current Master Refrigeration and Air Conditioning Mechanic license from the DC Department of Licensing and Consumer Protection (DLCP); verifying a contractor’s active DLCP license before authorizing work is the baseline due-diligence step.
