Furnace Repair in Dunn Loring, VA
When a furnace in Dunn Loring 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 Dunn Loring, Merrifield and Mosaic District. We answer 24/7, including nights and weekends.
What usually goes wrong
- Burners light and shut off within minutes
- Blower runs but the air is cool
- Furnace cycling on and off all day
- Error code flashing on the control board
- Loud rumble or squeal at startup
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 Dunn Loring homes
Homes in Dunn Loring are mostly older ramblers and Cape Cods mixed with newer townhouses and condos around the Mosaic District and the Metro. Older Dunn Loring houses often have ductwork that was sized for a smaller system, while the newer townhouses near the Metro usually run heat pumps with attic air handlers. Those details shape how we approach furnace repair in Dunn Loring: 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
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.
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.
Do you work throughout Dunn Loring?
Yes, from Merrifield to Pine Ridge and the streets off Gallows Road, Lee Highway and Cedar Lane.
