No-Heat Diagnostic
Flame sensor, igniter, pressure switch, roll-out limit. We find why it locked out and show you the fault code on the board.
No heat at six in the morning gets answered at six in the morning. Every install leaves with a combustion test printed and taped inside the cabinet.

Furnaces that light every time
Straight diagnostics. If a twenty-dollar part is the fix, we say so instead of quoting you a system.

80% or 96% condensing, sized off a load calculation and your actual ductwork — not off the sticker on the old one.
A cracked exchanger puts combustion gas in your supply air. Camera inspection and a CO reading, both in writing.
Hot surface igniters, flame sensors, inducer motors and control boards. The common parts ride on the truck.
New runs, sediment traps, and B-vent or PVC terminations that meet clearance. Permit pulled and inspected.
Burner cleaning, combustion analysis, CO test and a fresh filter. Booked from September so the first freeze isn't a discovery.

The furnace we're standing in front of right now — what failed and what it took. New one most weeks through the heating season. Real closets and basements in this metro.
Furnace rooms and closets across the metro, most of them photographed before sunrise.







A furnace can run and still be wrong. Numbers are the only thing that says which.
CO, stack temperature and temperature rise recorded and left inside the cabinet.
Sized to the house and the duct you actually have. Oversized furnaces short-cycle and cost you.
Igniters, sensors, pressure switches and inducers. Most no-heat calls end on the first visit.
Tune-ups start in September, because November is a bad month to find out.
Flueworks started in the fall of 2014 with a used van and a combustion analyzer. The analyzer cost more than the van, which tells you where the priorities were and still are.
We only do heat — furnaces, gas piping and venting, from the first no-heat call in October to the last one in March. Every install gets combustion-tested and the numbers stay taped inside the cabinet for whoever opens it next.

Blower running with no flame? Lighting, then shutting down after a minute? That one detail usually names the part before we're out of the driveway.
Call. Through the heating season the phone gets answered early, late, and on Sunday.
