Why Your GTA Home Needs a Whole-Home Humidifier

Ontario winters force us to run our furnaces constantly - which strips moisture from the air. The average GTA home in January has less than 20% relative humidity indoors. Ideal is 35–50%.

Feel Warmer at Lower Thermostat Settings

Humid air holds heat better. A properly humidified home at 68°F feels as warm as a dry home at 72°F - saving on heating bills.

Protect Wood Floors & Furniture

Dry air causes hardwood floors to crack, furniture to warp, and door frames to shrink. Proper humidity protects your investment.

Eliminate Static Electricity

Dry indoor air causes annoying static shocks. Proper humidity (35–50% RH) eliminates static completely.

Reduce Illness & Dry Skin

Dry mucous membranes are more susceptible to viruses. A whole-home humidifier keeps the air at the healthy 40–50% RH range.

Types of Whole-Home Humidifiers We Install

Not all humidifiers are the same. We'll recommend the right type based on your home size, heating system, and water quality.

Bypass Humidifier

Most common and affordable. Uses your furnace's warm air supply to evaporate water into the airstream. Best for homes with gas forced-air furnaces.

Brands: Honeywell, Aprilaire, GeneralAire
Ideal for: Average to large homes with gas furnaces

Fan-Powered Humidifier

Has its own fan for higher output. Works independently of your furnace blower - great for homes that need more moisture or have high ceilings.

Brands: Aprilaire 700, Honeywell HE360
Ideal for: Larger homes, open-concept layouts

Steam Humidifier

Boils water to create pure steam - the most effective type. Works with any heating system including heat pumps and hydronic heating.

Brands: Aprilaire 800, GeneralAire 1137
Ideal for: Homes with heat pumps, high-efficiency needs

Whole-Home vs Portable

Whole-home (furnace-mounted) humidifiers treat every room evenly. Portable units only cover one room and require constant refilling. We install whole-home systems.

Brands: All major brands available
Ideal for: Whole-home coverage, low maintenance

Whole-Home Humidifier FAQs

What humidity level should I maintain in my home in winter?

The ideal indoor relative humidity in a Canadian winter is 35–45%. Below 30% causes dry skin, static, and wood damage. Above 50% can cause condensation on windows and mold growth.

How often does a whole-home humidifier need maintenance?

The water panel (evaporator pad) should be replaced once per season - typically each fall before heating season. The unit itself should be cleaned annually. EcoFrost offers annual maintenance as part of our HVAC tune-up service.

Can I install a humidifier on a heat pump system?

Yes - a steam humidifier like the Aprilaire 800 works with heat pumps and all heating systems. Bypass humidifiers require a gas furnace with a traditional air handler.

How much does a whole-home humidifier cost to install in Mississauga?

Installed cost typically ranges from $400–$900 for bypass or fan-powered units, and $900–$1,800 for steam humidifiers. Contact us for a free estimate specific to your home.

My humidifier is making a gurgling noise - is that normal?

A slight water flow sound is normal when the unit is running. Loud gurgling or dripping can indicate a drain blockage or oversized water flow. Call us for a quick assessment.
