A furnace that won't ignite, short-cycles, or keeps tripping its limit switch needs more than a reset in Rockville winters. A CO check happens on every call, standard, not an upsell.
Furnace failures in Rockville cluster around a handful of parts — ignitors, flame sensors, gas valves, heat exchangers. We test with real equipment, not parts-cannon guessing.
Safety and accuracy on every heating call.
A combustion analyzer reading for dangerous CO levels is part of every visit, not optional.
No-heat calls in Rockville get priority routing over routine work during cold snaps when it's cold.
A fixed price is set before repairs start.
Both fuel types get the same trained tech, no exceptions.
The most common furnace failure points.
Cracked ignitors and carbon-fouled sensors cause a large share of no-heat calls, usually a same-visit fix.
We test actual response and pressure output rather than replacing an expensive part on a hunch before we recommend replacing it.
We inspect carefully with proper equipment rather than assuming based on age.
We test both before condemning the control board.
We still service older standing-pilot systems that newer ignition doesn't have.
Zero response from the furnace can mean a wiring fault, not a furnace failure to avoid overcharging for parts you don't need.
What happens from your call to heat restored.
Tell us what the furnace is doing and we'll get someone moving.
Truck arrives stocked with common ignitor, flame sensor, and control parts ready to diagnose and often repair same visit.

Most repairs finish same visit, with a final CO check before we leave, backed by warranty.
Recent reviews from winter heating calls.
Pilot light kept going out on our older furnace every few days. Tech identified a failing thermocouple that two other companies had overlooked.

Furnace made a loud bang on startup that scared the whole family. Turned out to be a delayed ignition issue from a dirty burner, cleaned and resolved same visit.
— F. Ibekwe, homeowner
Called about a gas smell near the furnace closet and they had someone here within the hour to confirm it was safe before doing any repair work.
— Q. Whitmore, homeowner
Landlord here with an older building, they've kept three separate furnace units running through two winters without a single emergency callout.

We still service these older systems.
We prioritize no-heat situations even during high demand.
Common parts are stocked, rare ones may need next-day ordering to finish the repair.
