4 factors the cost of a new furnace depends on:
Environmental choices, including energy efficiency, air filtration sizes (which are dependent on allergies or other sensitivities), humidification, and comfort-enhancing options.
Depending on your personal choices you can get extended warranties, maintenance plans and guarantees.
Technical requirements including the size of the home, number of stories, floor plan, existing ductwork and BTU load.

What is the expected life of a Furnace?
The average lifespan of a furnace is about 15 years, but its age is not the only factor to consider. Other reasons to replace your furnace may include safety, frequency of breakdowns, improper sizing and quality of installation.
How often should you change your furnace filter?
We recommend that you change or clean your furnace filter every 1 to 3 months.
Is it necessary to get a humidifier?
If the humidity in your house is lower than 30 % on a hygrometer it is always recommended that you consider a humidifier. Health Canada recommends a house relative humidity should be between 30% and 55% during winters. Most homes will require a humidifier in Canada due to the dry air created by the cold climate.
How Does a Furnace Work?
- A natural gas or propane high-efficiency furnace will start up when the attached thermostat senses that the temperature around has dropped below a pre-set level.
- Just before the furnace starts, the ventor motor does a safety check to ensure that the venting is clear, as determined by the pressure switch. The ignitor then ignites the burners present inside the furnace combustion chamber and after that it starts creating heat. The heat is then transferred to the primary or “first” heat exchanger which heats the air as it flows through the furnace. Later, the combustion gases are passed through a secondary heat exchanger for further extract heat.
- The blower motor then pushes the warmed air through the plenum and out into the house through the registers.
- The combustion gases, like carbon monoxide, are safely vented to the outdoors from the furnace.
- In maximum cases, fresh air from outside is pulled into the burn chamber to provide the most efficient burn. However, this is not practiced at old homes.
- Any cold air left in the house gets circulated into the furnace to be heated.
