Heating, Ventilation & Air Conditioning Options for Ottawa
Ductless Mini-Split Air Conditioners & Heat Pumps
Ductless mini-split air conditioners & heat pumps are a great option for retrofit add-on to homes with “non-ducted” heating systems, such as hydronic (hot water heat), radiant heat, or baseboard electric heat. Ductless mini-split air conditioners and heat pumps can also be a good choice for supplemental heating and cooling in rooms or additions where installing duct work is not practical.

Friedrich ZoneAire® Portable Air Conditioner
ZoneAire is like having multiple appliances in one convenient unit: an air conditioner, a dehumidifier, a fan and a heater (heat pump model only). It’s practical and flexible: because the unit can move with you to any room, you get cooling exactly when and where you need it. The dehumidification mode keeps your space comfortably dry, and there’s no bucket to empty. When you just want a gentle breeze, switch to fan mode. Remote control included.

Gas & Propane Furnaces
In Ottawa, and most of Canada, Gas Furnaces are the most economical home heating choice. Propane Furnaces are identical to Gas Furnaces, with minor adjustments to enable them to operate on a slightly different gas pressure.
Current and trending energy costs in Ottawa and Ontario make a Gas Furnace, by far, the most economical and most comfortable home heating option.

Hot Water Boilers
Boilers are very common in the older parts of Ottawa. Boilers heat water in order to distribute heat throughout the home using radiators, or radiant heat provided by heating and entire surface. The most common radiant heating is provided through floor surfaces which are heated by tubing installed in concrete or a lightweight gypcrete which can be poured over existing floor surfaces.

Heat Recovery Ventilators HRV / ERV
The fundamental principle of indoor air quality starts with eliminating the source of common indoor air quality problems like moisture which can lead to mold, mildew and other unhealthy contaminants. Air exchangers will control unwanted humidity in winter, as well as dilute concentrations of gaseous pollutants like VOC’s (Volatile Organic Compounds) that come from many household sources.
