A furnace that won't ignite, short-cycles, or keeps tripping its limit switch needs more than a reset in Northport winters. A CO check happens on every call, standard, not an upsell.

A short list of components causes most Furnace Repair calls: ignitor, flame sensor, gas valve, heat exchanger. We test with real equipment, not parts-cannon guessing.
What doesn't change from visit to visit.
Every repair includes a CO check, not optional.
We bump no-heat calls ahead of routine visits when it's cold.
Ignitor or heat exchanger, the price is quoted and approved before work begins.
Our techs are trained equally on gas furnaces and electric heat strips, no exceptions.
Six repairs that cover most of our winter calls.
These two parts are behind most no-heat visits, 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.
A cracked heat exchanger can leak combustion byproducts into the airflow — we inspect with a scope and analyzer rather than assuming based on age.
We test both before condemning the control board.
Older Northport furnaces with standing pilots have their own failure points — thermocouples, pilot orifices, draft issues that newer ignition doesn't have.
We rule out wiring issues first to avoid overcharging for parts you don't need.

Feedback from completed furnace repairs.
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.

Landlord here with an older building, they've kept three separate furnace units running through two winters without a single emergency callout.
