What is a Furnace?

Furnaces are designed to heat an entire home and they come in a range of sizes. All furnaces are equipped with an air exchanger to transfer the heat generated by natural gas combustion, electricity, or fuel. They are also equipped with a blower motor that propels the heat to the rest of your home through the pipes. Even in the hot season, when the heat is off, the furnace serves as a central distributor for your home’s forced-air system.

Types of Furnaces

What are the types of furnaces and their advantages?

Furnaces available on the market are powered by four different energy sources with their advantages and disadvantages.

Natural gas

The natural gas furnace provides safe and uniform heat. Its main drawback is the fact that this energy source is non-renewable.

Propane gas

The propane gas furnace instantly produces heat and leaves no residue. On the other hand, its energy is not renewable, and it sometimes spreads polluting particles.

Fuel oil

The oil furnace provides excellent heat circulation. However, this type of heating can emit harmful particles in addition to using non-renewable energy.


The electric furnace emits no pollution, is affordable, and requires little maintenance. Its primary disadvantage is that it stops working during a power failure.

Pros and Cons of Different Types of Furnaces

The choice of a furnace model depends significantly on the type of energy available in your home:

  • Electricity
  • Fuel oil
  • Gas

Each type of furnace has its pros and cons. The most efficient systems will run on fuel.

A furnace is a central unit that can heat your entire home. It mainly comes in two types:

The furnace for the forced-air system

A forced-air system distributes the air heated by the furnace through a network of ducts and hatches, thus heating the air in your home. With the addition of filters and humidifiers, this system allows reasonable control of the air quality in your home.

The furnace for the hot water system

The heat is distributed by the passage of hot water heated by the furnace in a system of pipes and radiators which run through the house. As heat is propagated by radiation rather than hot air, the result is the increased heating quality that does not dry out the air.

Already have a hot water system that you want to keep, but would like to improve its energy efficiency? Choose a high-quality furnace model.

The advantages of the electric furnace

These clean, quiet, and efficient devices provide electrically controlled comfort for a cottage, home, or office. That’s because they are supplied with “ultra-quiet” multiple speed fan and side or bottom access to the mixing box. You can also purchase a hard-wired kit for 120 or 240-volt power, air filters, and humidifiers. It can be mounted virtually anywhere: in a basement, closet, crawl space, nook or alcove. A hard-wired kit is also CSA approved for use as a built-in unit. It is not necessary to leave a free space between the furnace and combustible surfaces.

Versatility and more

Add an air conditioner, electric humidifier, or electronic air filter to get the comfort you want. Multi-speed motor… Versatile and practical standard equipment.

How Long Does It Take to Install a Furnace

The installation of a furnace will take you at least 4-5 hours. When it is installed, your technicians will have to do a test. They will fire it up and see if it is working correctly. They will then clean up everything and, if needed, get rid of the old parts of your previous furnace, in case you are replacing your furnace.

Factors that Might Affect Installation Time

To speed up installation time, you should make sure that the area it will be installed in is clean, empty, and well lit. Make sure there will be no kids near there for the installation duration and that your technicians are well-experienced and know precisely what they are doing!
