Furnace Basics
A furnace is a central heating system that heats air and then uses a blower motor and air ducts to distribute warm air throughout the house. Here are some basic aspects of a furnace:
There are three main types of furnaces:
- Single-Stage Furnace: This type of furnace has only one stage of operation. It can either be turned on or off, meaning it’s always running at maximum capacity and using maximum gas or electricity.
- Two-Stage Furnace: This type of furnace has two settings: full and half speed. This allows for a more efficient operation, as the furnace can run on the lower setting during milder weather.
- Modulating Furnace: This type of furnace can modulate the heat output and air velocity nearly continuously, depending on the demanded heat and outside temperature. This means it only uses the precise amount of energy necessary to keep your home comfortable.
Furnace Components
A furnace is made up of several components, including:
- Burner: This is where the fuel (natural gas, propane, or oil) is mixed with air and ignited to create heat.
- Heat Exchanger: This component separates the combustion process from your breathing air. It absorbs the heat from the flame.
- Blower: This part sends the heated air through your ducts and into the various rooms of your home.
- Exhaust Blower: This is the exhaust for harmful gases, including carbon monoxide, which are produced during the combustion process.
Efficiency Rating
Furnaces are rated by the Annual Fuel Utilization Efficiency (AFUE) ratio, which is a percentage that tells you how much heat the furnace can produce for every dollar of fuel consumed. A higher AFUE means greater energy efficiency. Remember, understanding the basics of how a furnace works can help you make an informed decision when it comes time to purchase a new one or maintain your current one. Always consult with a professional if you’re unsure about any aspect of your furnace’s operation.

- Poor Air Quality: If you notice an increase in dust, allergens, or dry air in your home, it could be a sign that your furnace is not effectively cleaning and humidifying the air.
Furnace vs. Heat Pump
A heat pump and a furnace are two different systems used for heating homes, each with its own advantages and disadvantages. Heat pumps are efficient heating and cooling systems ideal for temperate climates. They run on electricity, drawing heat from outside air—even in cold weather—and transferring it indoors. Heat pumps are typically more energy-efficient than furnaces and are capable of both heating and cooling. However, they produce less heat than furnaces and work best in warmer climate. On the other hand, furnaces generate heat by burning oil or gas. They provide more warmth, making them ideal for cold climates. Furnaces tend to last slightly longer than heat pumps, but they may cost more over time. Choosing between a heat pump and a furnace is ultimately a case-by-case basis. Homeowners in warmer climates can take advantage of heat pumps, while those in colder climates may prefer the warmth provided by furnaces. Additionally you can take advantage of Hybrid Heat Pump System. Remember, both systems require professional installation and maintenance. Proper maintenance can help extend your heat pump’s lifespan.
Hybrid Heat Pump System
A Hybrid Heat Pump System, also known as a dual fuel system, combines a traditional heat pump with a furnace. This system alternates between the heat pump and the furnace based on the season, temperature, and function needed, maximizing efficiency. In milder temperatures, the heat pump provides cost-efficient heat. When the temperature drops during the cold winter months, the furnace takes over. This combination allows you to enjoy the energy efficiency of a heat pump in moderate climates and the powerful heat of a furnace in colder weather. Now, let’s talk about the rebates and incentives. There are several programs available that offer financial incentives for installing a hybrid heat pump system:
-
Canada Greener Home Initiative: This program provides Canadian homeowners with grants of up to $5,000 to improve the energy efficiency of their homes. Over 82,000 households have purchased and installed a heat pump through this program4.
-
Enbridge's Clean Home Heating Initiative: Supported by the Government of Ontario, this program offers homeowners in select municipalities up to $4,500 towards installing a hybrid heating system.
- Federal Tax Credits and Provincial Rebates: Federal Tax Credits and State Rebates: In some regions, you could be eligible for up to $1,750 for a heat pump water heater and $8,000 for a heat pump for space heating and cooling.
Furnace Common Problems
The majority of furnace issues often stem from inadequate maintenance. Regular upkeep of furnace filters and blowers is crucial to prolong the lifespan of heat exchangers and blower motors.
