A whole-home humidifier connects directly to your furnace and water supply, automatically adding moisture to the air distributed throughout your home. Unlike portable units, it maintains consistent humidity in every room. Ideal humidity for Ontario winters is 35 to 50%, which reduces static electricity, dry skin, and protects wood floors and furniture.
A smart thermostat learns your schedule and preferences, automatically adjusting temperature when you are away or asleep. Most homeowners save 10 to 15% on heating and cooling bills. Ecobee and Nest thermostats also integrate with Ontario utility time-of-use rate programs, shifting energy use to lower-cost periods.
The GTA has some of the hardest water in Ontario, with high calcium and magnesium levels. A water softener removes these minerals, preventing scale buildup in your pipes, water heater, and appliances. Hard water can reduce water heater efficiency by up to 30% and cut appliance lifespan in half. Most GTA homeowners benefit from a water softener.
A whole-home HEPA filtration system installs in-line with your existing HVAC ductwork. All air circulated through your furnace or air handler passes through the HEPA filter, removing 99.97% of particles 0.3 microns and larger, including pollen, pet dander, mold spores, and fine dust. No portable units or manual filter changes are needed.
Yes. Most existing HVAC systems can be upgraded with whole-home air purification including electronic air cleaners, UV-C light systems, and HEPA bypass filters. EcoFrost installs all major brands and will recommend the best system for your specific equipment and home size.
