Answers to common HVAC questions from homeowners in the Falls Church area.
It depends on where your home is. In the City of Falls Church, a single-family home can replace an A/C or heat pump without a permit, but any work on a gas appliance, such as a gas furnace or water heater, needs a permit. Many homes with a Falls Church mailing address (ZIP codes 22041-22044) are in Fairfax County, where replacing a gas furnace, boiler or water heater needs a Household Appliance (HAPL) permit, even for a like-for-like swap. We check which jurisdiction your home is in before we start.
Only ZIP code 22046 is the independent City of Falls Church. Addresses in 22041, 22042, 22043 and 22044 use Falls Church as the mailing city but are in Fairfax County. The City of Falls Church website has an address finder if you are unsure.
