Falls Church guide
The questions Falls Church homeowners ask most.
Falls Church is a small independent city, and many homes with a Falls Church address are actually in Fairfax County. The ZIP code tells you which: ZIP 22046 is the City of Falls Church, while 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.
This matters because the permit rules differ. We serve both sides of the line, and we check which jurisdiction your address is in before we start work.
In the City of Falls Church, a single-family home can replace an air conditioner or heat pump without a permit, but gas appliance work needs a permit. In Fairfax County, replacing a gas furnace, boiler or water heater requires a Household Appliance permit and an inspection, even for a like-for-like swap, and the county lists new, replacement, repair or conversion of HVAC systems among the projects that need a mechanical building permit. Fairfax County Land Development Services can be reached at 703-222-0801. Source: Fairfax County Land Development Services.
A system that fails in a heat wave or on a freezing night cannot wait. We provide same-day service and 24/7 emergency repair in Falls Church, 365 days a year, with no extra charge for evenings, weekends or holidays. We do not quote a fixed arrival time, because it depends on the day and where our technicians are, so call us and we will give you a time when you book.
“In the middle of the worst heatwave in years, my air conditioner suddenly stopped working… I called AVS, and not only did they come out at 11:00 pm that very same evening, just a few hours after I called, they efficiently and professionally diagnosed the problem as a failed capacitor, replaced it, and had the air conditioner running again in just 15 minutes.” Rich, Google review
