How Long Does It Take to Replace a Furnace? 4 – 10 Hours

As long as your existing ductwork is in good shape and doesn’t need replacing or repairing, then the entire installation should be able to be completed in less than a day. The average time it will take is usually somewhere between 4 to 10 hours depending on the type and size of the furnace that you are installing. Larger, more complex units usually take a bit longer than smaller, basic units.

Most modern combustion furnaces will last between 15 and 20 years. Purchasing a new furnace is a large investment, so it is important to get the right size to meet the needs of your home and family for a long time. You also want to make sure that you have it properly installed by an HVAC technician with the experience and expertise to do the job correctly.

size of furnace you buy

Consider the Size of Your Home

The size of your home will determine the size of your new furnace. You don’t want a furnace that is too small, as it won’t have the capacity to heat your entire home and will probably wear out faster due to overexertion. Neither do you want one that is too big, as it will have too much heating capability. As a result, it will heat your home very quickly and then shut off quickly. Constant shutting on and off of your furnace is hard on the furnace, and it means that it won’t run as efficiently.

A trained professional can work with you to do a heat load calculation to determine the correct size of furnace to keep you and your family comfortable in your home. The factors they will consider include:

  • Your home’s floor plan and orientation
  • The amount of insulation you have
  • The number of people living in your home
  • The number and type of windows and doors you have
  • Your square footage

The following video will further explain a basic heat load calculation.

Decide on the Type of Furnace to Purchase

The two most common types of furnaces are electric and combustion. Most combustion furnaces today usually burn natural gas, but there are some that use propane or oil. An electric furnace doesn’t burn fossil fuels. They use electricity instead to generate heat. In Ontario, electric furnaces are more expensive to operate than natural gas, propane, or oil because of the current high cost of electricity.

Choose the Amount of Energy Efficiency You Want

Modern furnaces are much more energy efficient than they were in the past. The easiest way to determine a furnace’s level of efficiency is by taking a look at its AFUE (annual fuel utilization efficiency) rating. The higher the AFUE rating, the more efficient the furnace will be. You can find a furnace’s AFUE rating on its EnerGuide label (the Government of Canada mark found on a sticker on the outside of the unit).

“Our furnace was acting up, so I called Draft Control Heating and Cooling.  What I like immediately was talking to the owner.  You call and he picks up the phone.  He offered to come the next day, give a free inspection of our old furnace.  If the fix was simple, then he would repair it, if not he would give us a no pressure quote for a new furnace…If you are looking for an honest contractor that has competitive pricing that installs a very good brand, then definitely put Draft Controls Heating and Cooling on your short list.   I’d also recommend him for servicing heating and cooling.” – Christopher K.
