Question 1

What's the ideal indoor humidity in winter in Ontario?

Accepted Answer

30-40% relative humidity is the ideal range for Ontario winters. It's comfortable, prevents dry-skin and static issues, and avoids window condensation that causes mold.

Most KW homes drop to 15-20% in deep winter without a whole-home humidifier, which is why so many people feel dry and itchy from December to March.

Question 2

Do I need a whole-home humidifier?

Accepted Answer

If you wake up with a dry throat, see static cling on clothes and pet hair, notice cracking hardwood floors, or get nosebleeds in winter - yes, you do. A whole-home bypass or fan-powered humidifier ties into your furnace ductwork and conditions every room, unlike portable plug-ins that only humidify one space.

Question 3

HRV vs ERV - which is right for my home?

Accepted Answer

HRV (heat recovery ventilator) is the right choice for most KWC Region homes - it brings in fresh outdoor air, recovers heat from outgoing stale air, and doesn't transfer humidity. ERV (energy recovery ventilator) also transfers moisture, which makes sense in humid climates or homes that struggle to hold humidity in winter.

We measure your home's current humidity load before recommending.

Question 4

How much does an HRV cost installed?

Accepted Answer

Most HRV/ERV installs in the KWC Region run $2,500-$4,500 installed, depending on duct routing, exterior wall penetrations, and any electrical work needed.

Question 5

Do UV lights actually work in HVAC systems?

Accepted Answer

Yes - properly placed UV-C lamps on the cooling coil sterilize biofilm and prevent mold growth on the coil and drain pan. They don't replace good filtration, but they're a measurable hedge against indoor pathogens and they keep the coil cleaner over its lifespan.

Question 6

What MERV rating filter should I use?

Accepted Answer

MERV 8-11 is the standard range for most residential furnaces - effective for dust, pollen and pet dander without restricting airflow too much. MERV 13 captures finer particulates including some bacteria and smoke. Going higher (MERV 14+ or HEPA cabinets) requires careful matching to your blower; otherwise it starves the system.

Question 7

Why does my house feel dry in winter?

Accepted Answer

Cold outdoor air holds very little moisture. When it leaks into your home through ductwork, doors, windows and other gaps - then heats up - the relative humidity drops sharply. A whole-home humidifier adds enough moisture to the air to maintain 30-40% RH all winter.

Question 8

Can IAQ equipment be added to my existing furnace?

Accepted Answer

Yes. Whole-home humidifiers, UV lights, electronic air cleaners, and HEPA cabinets all integrate with your existing furnace and ductwork. HRV/ERV systems install in parallel with the existing system. We assess compatibility during the free in-home estimate.

Question 9

Are there rebates for HRV installation in Ontario?

Accepted Answer

HRV/ERV installs may qualify for Enbridge Home Efficiency Rebate when bundled with other envelope or equipment upgrades. We confirm eligibility at quote time and file the paperwork at no extra cost.

Question 10

Do you offer financing on indoor air quality equipment?

Accepted Answer

Yes. Financing options are available for qualified homeowners on new humidifier, HRV/ERV, air cleaner, and UV system installations.
