Inside Alexandria homes
Homes in Alexandria are mostly historic rowhouses in Old Town, 1940s garden apartments, and single-family homes in the West End. Historic Alexandria homes often have boilers or radiators in the original part of the house and a separate system serving an addition, which makes even heating tricky. So when you call for furnace repair in Alexandria, 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.
