Furnace Repair in Falls Church, VA
When a furnace in Falls Church won't stay lit or won't start at all, the cause is usually a sensor, an igniter, a pressure switch or a control board, not the whole furnace. Reliable HVAC McLean serves Falls Church, West Falls Church and Pimmit Hills. We answer 24/7, including nights and weekends.
What usually goes wrong

How we handle furnace repair
We test the ignition sequence step by step, clean or replace the flame sensor if needed, check the pressure switch and inducer, and finish with a combustion and carbon monoxide check.
About Falls Church homes
Homes in Falls Church are mostly brick colonials, Cape Cods and ramblers from the 1940s through 60s, plus newer townhouses and condos near Broad Street. Many Falls Church homes were built before central air, so ductwork was added later through closets and attics, and older homes here often have a gas furnace and an AC that were installed decades apart. Those details shape how we approach furnace repair in Falls Church: what equipment we expect to find, where it sits and how the ductwork is likely laid out.
Cost and timing
Flame sensors, igniters and pressure switches are common, affordable fixes that we usually finish on the first visit. Control boards and inducer motors cost more. On a furnace past 15 to 20 years, we'll compare the repair against replacement so you can make the call.
Questions we hear
Why does my furnace shut off after a few minutes?
Most often a dirty flame sensor, an overheating limit switch from a clogged filter, or a venting problem. All three are quick to diagnose.
Is a burning smell from the furnace normal?
A dusty smell for the first few minutes of the season is normal. A strong burning smell, or any gas smell, is not. Turn it off and call.
Do you work throughout Falls Church?
Yes, from West Falls Church to Holmes Run and the streets off Broad Street, Lee Highway and Route 7.
