About our whole-home humidifiers service

Simcoe County winters routinely drop indoor humidity below 20%. Whole-home humidifiers hold your home in the healthy 35–45% range automatically. We install and service bypass, fan-powered, and steam humidifiers.

Simcoe County winters run bone dry indoors. When a high-efficiency furnace is running hard through a January cold snap in Innisfil or Springwater, relative humidity in the house can sit in the teens, which is where you get static shocks, cracking hardwood, and split trim on newer Alcona builds. We install bypass and steam humidifiers wired to a humidistat with outdoor reset, so the setting drops automatically before you get condensation running down the windows.

What's included

  • Bypass, fan-powered, and steam models
  • Installation, repair, and annual service
  • Automatic humidity control
  • One annual pad change, that's it

Where we provide whole-home humidifiers

Innisfil is home base, and our trucks run the same routes daily across Simcoe County and north York Region.

  • Barrie Barrie's older downtown and Allandale homes leak air at the envelope but not at the ducts, which is exactly the combination that leaves upstairs rooms stale.
  • Bradford West Gwillimbury Marsh soil and farm activity around Bradford push a lot of fine dust indoors, and filtration there earns its keep every spring.
  • Essa Rural Essa properties on well water and gravel roads deal with grit that a one-inch filter simply cannot hold.
  • East Gwillimbury Newer Queensville and Sharon homes are sealed tight enough that mechanical ventilation is the only thing keeping indoor humidity in range.
  • Springwater Wood heat is still common through Elmvale and Hillsdale, and combustion particulate is the main air-quality concern we address there.
  • Newmarket Allergy complaints in Newmarket peak with the spring pollen load, and a properly sealed return does more than any add-on filter.
  • Oro-Medonte Walk-out basements and lakeside crawlspaces across Oro-Medonte drive the summer humidity problems homeowners call us about.
  • New Tecumseth Alliston's mix of farmland and industry means both pollen and fine particulate, so we usually spec media depth over gimmick features.
