At Aire One KW, we carry the following types of furnaces:


  • Natural gas furnaces are extremely energy efficient. Although expensive upfront, gas furnaces are typically cheaper in the long run due to low fuel costs. For example, a gas furnace can reach the desired temperature faster than an electric-powered one, consuming less fuel and saving you money.

  • Electric furnaces use electric heating elements to provide warmth. They’re cheap to buy and install and smaller than other types of furnaces, making them suitable for small spaces. Additionally, since electric furnaces don’t use gas or oil, you don’t have to worry about dangerous oil or gas leaks. They also don’t produce carbon monoxide.

  • Propane furnaces are efficient and reliable. For instance, in a power outage, propane systems continue to work, whereas electric heating systems would be out of service. Moreover, propane contains more heating capacity in BTUs (British Thermal Units) per cubic foot than other types of furnaces. This means it heats up fast and stays warm for a long time.



Speak with the team at Aire One KW about your home’s needs, what fuel sources are available, how much space you need to heat and we can recommend the best possible model for you. Contact us in Kitchener-Waterloo,  Cambridge, Guelph and Woodstock for more information.

  • How often should I service my boiler?
    A minimum of once a year is recommended. Heating systems come on an average of 3-8 times per hour during the heating season, these numbers can change dramatically in different style of homes and with different thermostats, but this is a rule of thumb in our industry. There is a lot of wear and tear on the appliance and setting can go out of calibration. Also, it is a requirement by most manufacturers and home insurance companies.
  • Can I add new zones to my existing boiler heating system?
    It depends if the btu output of the radiators has reached the maximum btu output the boiler can support. Having a professional to come out and calculate is your best bet.
  • How will I know if the boiler I select will work properly for my home?
    Each room will have a radiator and every radiator has a specific btu output . We calculate the total of the radiator btu outputs, match that with a heat loss/heat gain calculation for the home and that is how we size a boiler system for your home.
  • How does a boiler work to heat my home?
    A boiler is a device that heats water and then distributes the hot water throughout your home to warm the indoor air. There are two main types of boilers: hot water boilers and steam boilers. Hot water boilers heat water to a temperature of about 82 C. The hot water is then circulated through a system of pipes and radiators throughout the home. The radiators give off heat to the surrounding air, which warms the home. Steam boilers heat water to a temperature of about 100 C, which is the boiling point of water. The steam is then distributed through a system of pipes and radiators throughout the home. The steam condenses back to water on the radiators, which gives off heat to the surrounding air, warming the home. In both hot water and steam boilers, the water in the pipes cools and returns to the boiler after heating the interior spaces. The water is then reheated and recirculated throughout the home. Some boiler models also double as a water heater, eliminating the need for a separate water heater unit. The efficiency of a boiler is measured by its Annual Fuel Utilization Efficiency (AFUE) rating. The AFUE rating is a percentage of the fuel that’s used to heat the water that heats the home. The higher the AFUE rating, the more efficient the boiler. Boilers with medium levels of efficiency have ratings of 90 to 93 per cent.
  • What is the average lifespan of a residential boiler?
    The typical residential boiler can last between 15 and 20 years. You can find the year your boiler was manufactured by checking the unit’s rating plate. You can also call the manufacturer and give them the unit’s serial number to find out how old your boiler is. If your boiler unit is more than 15 years old, you should consider replacing it with a new boiler, high-efficiency gas furnace or heat pump.
  • Are there any government rebates available for my boiler upgrade?
    Unfortunately, Ontario homeowners in the Tri-Cities area wanting to invest in a new boiler system for their homes aren’t eligible for rebates under the Home Efficiency Rebate Plus (HER+) program. Heat pumps are the only home heating system covered under HER+, whereby homeowners can get more than $10,000 in rebates on a heat pump installation. This program combines the Enbridge Gas rebate program and the Canada Greener Homes Grant.

Our New Furnace Works Like A Charm

Great experience, Aire One KW were very quick to respond and dealt professionally with our site specific requirements. The quoting process was straight-forward and transparent, and the installation itself is very good. Our new furnace works a charm, and I'm confident it will last for years to come. Choosing a professional HVAC installer is almost as important as the equipment itself, and I'd happily recommend Aire One
