What to Expect When You Have a New Furnace Installed



Whether your old one bit the dust or it’s time for an upgrade, installing a new furnace is a major investment. Contrary to popular belief, installing a new heating system isn’t as easy as you think. If done incorrectly, for example, you could void your furnace’s warranty. Moreover, in Ontario, TSSA certification is required to install furnaces that run on gas or propane. Here’s what to know about the installation process.

Choose a furnace

Before any work is done, you must decide if you’ll keep the same kind of furnace or switch to something different. For example, if your current system runs on oil, switching to gas, propane or electricity makes a lot of sense given the steep rise in the cost of heating oil. Additionally, if anyone in your family suffers from dry skin, you may want to consider a boiler system, which heats your home without drying out the air.

Remove the old furnace

Next, the technician must remove your old furnace before installing the new one. This step typically takes a few hours. On top of the air ducts, the fuel input must also be safely disconnected to avoid a dangerous leak. Once this is done, the unit can be unfastened and taken out. Depending on the type and model, furnaces can weigh 35 to 115 kilograms.

Connect the new furnace

The next step is bringing in the new furnace and securing it. Once this is taken care of, the technician can connect the air ducts and power source. Then, the thermostat must be correctly installed to ensure the furnace knows when to turn on and off. Aditionally, if you have a central humidifier or ventilator, these systems must be hooked up at this time.

Test the new furnace

Before leaving your home, the technician will test your furnace to ensure everything’s working as it should. This involves assessing the air intake and output to make sure there aren’t any leaks or other inefficiencies.
