What to know about HVAC Service in Fairfax
City line or county side
The City of Fairfax permits separately from Fairfax County. Burke, Annandale, Chantilly and Fair Oaks are county addresses people call Fairfax. Where the property sits decides where the permit is filed and who inspects.
Two kinds of house, two kinds of job
Mosby Woods, the largest neighborhood in the city, and Fairfax Acres and Green Acres date from mid century, with ducts sized for the equipment of that era. Newer county subdivisions are tight and zoned. Modern equipment in an older house usually means reworking the returns, not just swapping the box.
Fairfax repairs come with three questions
Inside the city line, Mosby Woods, Fairfax Acres and Green Acres were laid out decades before today's equipment, and the newer county subdivisions around them were built for it.
So a repair call here often turns into three questions, about the part, the ducts and the permit office.
The local concept
The undersized return
An undersized return is a return air path too small for the system it feeds, so the blower strains and the far rooms never catch up.
In Fairfax it shows up when a bigger modern system goes into a house whose return was cut for older equipment. Fix the return and the same system cools and heats better, with less wear on the blower.
Try this. Hold a tissue to the return grille with the blower running. If it barely moves, or the grille is one small square for the whole house, the return is likely part of the problem.
Fairfax repair calls
AC that runs all afternoon
On a hot day the system runs and runs and the upstairs never cools. In Mosby Woods and Green Acres the usual suspects are a dirty coil, a low charge or a return that is too small.
Furnace trouble in the first cold week
The first cold week is when ignitors, flame sensors and inducer motors that limped through last spring finally quit. A fall check catches most of them.
Older houses near the courthouse
Houses near Old Town Fairfax and the Fairfax County Courthouse have tight mechanical spaces and older wiring. Repairs there start with what's actually installed, whatever the label says.
Rentals near George Mason
Landlords with townhouses and rentals around George Mason University book repairs during a lease and tune-ups between tenants.
Condos along Fairfax Boulevard
Condos and apartments along Fairfax Boulevard toward Fairfax Circle have compact closet systems, where a failed capacitor or a clogged drain line stops everything.
Heat pumps in the county subdivisions
Many newer subdivisions outside the city line heat with heat pumps. A unit that iced over or blows lukewarm air in a Fairfax winter is usually a defrost or charge repair.
