Furnace Humidifier Cleaning in Toronto

Is it urgent?

This week

A humidifier left running with a blocked pad or a stuck valve is the most common way water gets into ductwork, which is how the mould on this site starts.

Two things override everything on this page. If anyone has symptoms of carbon monoxide exposure — headache, nausea or dizziness that improves outdoors — leave the building and call the gas utility or the fire service, not a duct company. And if a dryer smells of burning while it is running, stop using it: lint is an ignition source and that smell is the warning.

Signs to look for

Condensation on windows in winter, which means too much humidity
A white crust on the humidifier pad or in the tray
Water staining under or beside the humidifier
Static and dry air despite the humidifier running, which means it is not

How the work is done

Replace the pad or descale the cylinder rather than rinsing it
Clear the drain line and confirm it runs
Check the solenoid valve closes fully, which is the usual failure
Set it for the season and explain what it should be through winter

In Toronto specifically

Toronto's humid continental — long cold winters, humid summers, and a freeze-thaw shoulder season either side climate and its housing stock — Victorian and Edwardian semis through the old city, postwar bungalows and backsplits across Scarborough, North York and Etobicoke, and a downtown core that is almost entirely towers — decide what is worth doing first. Anything involving the gas appliance itself belongs with a TSSA-registered contractor, which duct cleaning is not. Ontario does not licence duct cleaning, so the checks worth making are liability insurance, a WSIB clearance certificate, and whether the technician holds NADCA certification — voluntary, but it means something.

Before the technician arrives

Four things worth doing — and the first one is usually the thing people get wrong.

Note the make and model from the casing if you can.
Check for staining or standing water underneath it.
Say what the humidistat is set to, if there is one.
Turn the water off to it if you can see a leak.

How it works

Three steps, and you decide at the end of them.

1
You call and describe the problem

Tell us what you have noticed and where — the room, the smell, the noise, how long it has been going on. Give us your postal code and we will match you to a licensed company covering your area. There is no form to fill in.
2
A local company takes it from there

They discuss the problem with you directly, arrange a time to inspect, and agree the work and the price with you before anything starts. That conversation is between you and them.
3
You decide whether to go ahead

You are under no obligation. If the quote or the approach is not what you wanted, you are free to say no and call someone else.

Furnace Humidifier Cleaning — FAQs

Do I actually need Furnace Humidifier Cleaning done?

A humidifier left running with a blocked pad or a stuck valve is the most common way water gets into ductwork, which is how the mould on this site starts.

What does Furnace Humidifier Cleaning involve?

Replacing the pad or cleaning the cylinder, clearing the drain, and checking the valve actually shuts. Also checking it is set sensibly for winter rather than left at one number all year.

What makes this different in Toronto?

Toronto's humid continental — long cold winters, humid summers, and a freeze-thaw shoulder season either side climate and its housing stock — Victorian and Edwardian semis through the old city, postwar bungalows and backsplits across Scarborough, North York and Etobicoke, and a downtown core that is almost entirely towers — decide what is worth doing first. Anything involving the gas appliance itself belongs with a TSSA-registered contractor, which duct cleaning is not. Ontario does not licence duct cleaning, so the checks worth making are liability insurance, a WSIB clearance certificate, and whether the technician holds NADCA certification — voluntary, but it means something.

Are the companies licensed and insured?

Yes. We only work with licensed, insured partners in Toronto, and you are welcome to ask to see a licence number on arrival.

What does Furnace Humidifier Cleaning cost?

It depends on the property, the size of the system and what the inspection finds, so we do not publish a price — a figure quoted on a web page is not one the attending company has agreed to. You get a price before any work starts.
