Do You Really Need a Furnace with a Heat Pump?

Do You Really Need a Furnace with a Heat Pump?

Many Canadian homes use heat pumps for heating and cooling. A heat pump is an energy-smart choice. It alone can handle mild winters and maintain comfortable indoor temperatures if you do not live in the coldest regions. So, many homeowners wonder if a furnace is also necessary to handle extreme cold. Do you need a furnace with a heat pump? Let’s explore options for reliable heating in colder climates.

How does a heat pump work?

A heat pump is a versatile HVAC system that provides both heating and cooling. Traditional systems burn fuel to create heat, and a heat pump moves heat from one place to another. It uses a compressor and refrigerant to absorb and release heat. Actually, it is an energy-efficient alternative for temperature control. So, it only transfers heat but does not create it. A heat pump has two cycles: heating and cooling:

  • In cooling mode, the refrigerant absorbs indoor heat, passes it through a compressor, and releases it outdoors.
  • In heating mode, the process reverses – the refrigerant captures warmth from the outside air and delivers it inside.  

Heat pumps are efficient in mild climates since they can switch between heating and cooling. Does a heat pump replace a furnace? No, in very cold climates, a heat pump alone may struggle to keep up. In those cases, it’s often paired with a furnace to provide extra warmth during freezing weather.

The benefits of heat pumps

Why choose a heat pump?

  • Year-round comfort. It provides both heating and cooling and is useful for any season.
  • Energy efficiency. It transfers rather than generates heat and saves energy consumption.
  • Improved air quality. It reduces moisture and filters out particles for healthier air.
  • Low maintenance. It requires less upkeep than traditional heating systems.
  • Cost savings. You will enjoy lower operating and maintenance costs over time.
  • Eco-friendliness. A heat pump produces fewer greenhouse gas emissions.

What is a furnace and its types?

Furnaces are common in colder areas because they generate heat directly. They burn fuel like gas or oil or use electricity to produce consistent warmth even when temperatures are freezing. Most often, Canadian homeowners use the following types of furnaces:

  • Natural gas furnaces. These are the most popular choices because they are affordable and efficient.
  • Propane furnaces. These are common in rural areas where natural gas is not available.
  • Oil furnaces. These are often found in places without access to natural gas.
  • Electric furnaces. These are convenient but usually more expensive.

A heat pump vs. furnace

Let’s compare the pros and cons of these two systems.

  • Cost. Talking about upfront investment, heat pumps can be pricier to install, especially without existing ductwork. Furnaces are generally cheaper initially. However, look at ongoing costs – heat pumps are energy-efficient, and over time you will benefit from lower energy bills.
  • Maintenance. Heat pumps need regular care—you will have to clean the coil and check the refrigerant quite often. Furnaces require less frequent maintenance, but annual inspections and tune-ups are still needed.
  • Performance. It all depends on your climate. Heat pumps work excellently in moderate climates but struggle in extreme cold. Furnaces provide reliable warmth in colder areas.
  • Energy efficiency. Heat pumps are very efficient because they only move heat and use less energy. But in cold weather, they need to work harder to keep homes warm. In harsh climates, a furnace could use less energy.
  • Lifespan. Heat pumps last around 15 years since they run year-round for heating and cooling. Furnaces, used mostly in winter, can last over 20 years. Keeping up with maintenance helps both last longer.
  • Appearance. Heat pumps can be visible, with units both inside and outside, or wall-mounted for ductless systems. Furnaces are usually hidden in basements or attics, with vents distributing heat. So, heat pumps tend to be more noticeable, while furnaces stay out of sight.
  • Installation. Heat pumps are easier to install if you already have ducts, and ductless options need less work. Furnaces usually need more setup, especially in homes without ducts, making installation a bit more complex. A professional installer can help decide the best setup for comfort and efficiency.

No matter whether you are going to purchase a heat pump or a furnace, make sure to check the SEER (Seasonal Energy Efficiency Ratio) for heat pumps and AFUE (Annual Fuel Utilization Efficiency) for furnaces. Additionally, check the noise ratings, especially for heat pumps, and existing ductwork in your home. Finally, the installation costs and maintenance requirements must be checked.

How does a heat pump work with a furnace?

A heat pump and furnace combination is often called a dual-fuel system. What is heat pump furnace duo for? It provides the best of both worlds for heating and cooling your home. Here’s how they work together to keep you comfortable:

  • Heat pump mode. In mild weather, the main load is on a heat pump. This option is energy-saving and is perfect for spring and fall when temperatures are moderate.
  • Furnace mode. When winter temperatures drop significantly, the heat pump can let you down. At this point, the furnace steps in. It easily delivers additional heat to keep your home cozy and warm.

Benefits of combining a heat pump and furnace

Do not fully replace furnace with heat pump, as each of them have unique pluses. What will you win if you use them both?

  • Enhanced energy efficiency. If you switch the heat pump when it gets warmer during the heating period, you can reduce your energy use and save on utility bills.
  • Improved comfort. This system ensures continuous heating, even during the coldest months, so you won’t have to worry about sudden drops in temperature.
  • Longer heat pump lifespan. By relying on the furnace during extreme cold, you lessen the workload on the heat pump, which can extend its lifespan.
  • Reduced environmental impact. Using the heat pump as your main heating source can significantly lower your carbon footprint, contributing to a more sustainable home.

Wrapping up

Choosing between a heat pump and a furnace depends on your climate, energy costs, and preferences. An HVAC professional can help determine the best fit for your home. However, do not rush to rely just on one device. It is not worth replacing furnace with heat pump, as you may need both of them for the comfort of your home. This duo will help you save money and get reliable heating throughout the year. If you’re considering this setup, discuss your options with a qualified HVAC professional.
