Furnace Repair in Vienna, VA
When a furnace in Vienna 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 Vienna, Vienna Woods and Wolftrap Woods. We answer 24/7, including nights and weekends.
What usually goes wrong

- Blower runs but the air is cool
- Furnace cycling on and off all day
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 Vienna homes
Homes in Vienna are mostly 1950s and 60s split-levels and ramblers on quiet streets, along with plenty of newer infill homes built where older houses were torn down. Vienna has a real mix: original-era gas furnaces in older split-levels next door to brand-new homes with two-stage heat pumps and smart zoning. Those details shape how we approach furnace repair in Vienna: 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
How do I know if my furnace is too old to repair?
Age, repair history and the cost of the part all matter. We'll give you an honest repair-or-replace recommendation instead of pushing one or the other.
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.

Yes, from Vienna Woods to Oakton and the streets off Maple Avenue, Nutley Street and Route 123.
