Inside Del Ray homes
Homes in Del Ray are mostly early 1900s bungalows, foursquares and rowhouses, many with additions built decades later. A lot of Del Ray houses were never designed for central air, so systems were added in attics, crawlspaces and closets over the years, and older ductwork is common. So when you call for furnace repair in Del Ray, we already know what we're likely walking into.
How it works
We run the ignition sequence, check the flame sensor, igniter, pressure switch and inducer, then fix the failed part and test for safe combustion.
Straight pricing
Common parts like sensors and igniters are quick, affordable fixes. Bigger parts get a clear price first, and on an old furnace we'll give you the replacement number too.
Quick answers
Why does my furnace light then shut off?
Dirty flame sensor, overheating from a clogged filter, or a venting issue. Usually a quick fix.
My furnace is in a tight closet. Can you still work on it?
Yes. Tight closets and attic units are normal for us in Arlington-area homes.
Do you cover all of Del Ray?
Yes. Rosemont, Potomac Yard, Old Town Alexandria and everything around Mount Vernon Avenue.
