What usually
turns out to be wrong.
Furnace maintenance is the visit that keeps a winter quiet. It gets booked when nothing is wrong, so the unit comes apart on a mild afternoon rather than on the coldest night of the year. The work itself is unglamorous: a burner assembly cleaned, a sensor read, switches proved, a drain flushed, a temperature rise measured. What it buys is a furnace that starts when the house asks it to, and a plain account of what is wearing and what is not.
Nobody knows when it was last done
Common in a house you’ve just bought. The furnace may be fine, but nothing on it tells you that, and the first proof either way arrives on a cold night. A service is the cheaper way to find out.
The flame is yellow and lazy
A gas burner should run blue and steady. Yellow, drifting or uneven flame across the burners points to dust and rust scale in the ports, or to a combustion air problem in the room around it.
A burning smell that doesn’t fade
Dust on a burner burns off in the first hour of the season. A smell that lasts beyond that, or comes back every cycle, means something is getting hot that shouldn’t, and it’s worth looking at.
Grey filter, uneven rooms
Restricted return air makes a furnace overheat and shut down on limit, and it makes the far bedroom cold. We check the filter, the blower compartment and the temperature rise together, since they’re one problem.
It has got noisier since last winter
Rattles, a whine that rises with the blower, or a rumble at start-up. Blower wheels load up with dust and go out of balance, and inducer motors get louder for months before they stop.
The furnace is over ten years old
Nothing fails on a birthday, but wear stops being theoretical. Igniters crack, pressure switch hoses harden, drain traps silt up. Past ten years, the yearly visit earns its cost more often than not.
What the job includes.
Burners and the combustion side
The burner assembly pulled where the design allows, ports cleared of dust and rust scale, and the flame pattern watched across all of them once it’s back together.
Flame sensor and igniter
The sensor cleaned back to bare metal and its signal read, and the hot surface igniter checked for the hairline cracks that end its life mid-winter.
Switches, inducer and the terminals outside
Pressure switch and its hose, rollout and limit switches, the inducer motor, and the intake and exhaust terminals outdoors, which is where nests and drifted snow do their work.
Condensate and drainage
On a condensing furnace the trap and its drain line get flushed rather than glanced at, since that is where the water leaving the exchanger drops everything it is carrying.
Airflow, blower and the readings
Filter checked, blower compartment cleaned, temperature rise measured across the exchanger, and a carbon monoxide reading taken with the unit running.
How the visit goes.
- 01Booked ahead of the coldAutumn is the sensible slot. We work 7 a.m. to 9 p.m., seven days a week, so the visit can sit outside a working day.
- 02Run it before we touch itThe furnace goes through a full cycle first, from cold, so we see how it starts and how it behaves before anything is cleaned.
- 03Panels off, clean and checkBurners, sensor, igniter, switches, inducer, trap and blower compartment, gone through in order with the gas isolated where it needs to be.
- 04Readings, then a plain reportTemperature rise measured, carbon monoxide read with the furnace running, and you hear what’s fine, what’s wearing and what needs nothing.

Furnace Maintenance questions.
If yours isn’t here, the phone is the fastest way to have it answered, seven days a week.
Once a year, and early autumn is the sensible time, before the first cold night rather than after it. A furnace that ran all last winter has a summer of dust on the burners and a flame sensor slowly coating over. Booking in September or October also means the visit happens while you aren’t waiting on heat.
Before the cold snap.
Describe the fireplace that won’t light or the water heater on its last tank, and we’ll tell you what the fix takes.
