Here’s a step-by-step look at what happens when you install a new furnace in your home.

How Should You Prepare for a New Furnace Installation?

Before installation, a professional HVAC technician will typically visit your home for an assessment. This ensures that the new furnace is the right size for your space and meets your heating needs. The technician will also check your existing ductwork, ventilation, and electrical connections to make sure everything is in good shape.

It’s a good idea to clear the area around your furnace so the crew has plenty of space to work. If you have pets or kids, plan to keep them away from the work area for safety.

What Happens to Your Old Furnace?

On installation day, the first step is removing the old unit. This includes:

  • Shutting off the power and gas supply
  • Disconnecting the old furnace from the ductwork and vents
  • Safely removing and disposing of the old system

This part of the process can take a few hours, depending on how accessible your furnace is and whether any additional modifications are needed.

What Happens During New Furnace Installation?

Once the old system is out, the new furnace is carefully positioned and connected to your ductwork, gas line, and electrical system. The technician will ensure:

  • Proper alignment with existing ductwork
  • Secure gas and electrical connections
  • Correct airflow and ventilation

A furnace installation in Edmonton, AB requires compliance with local building codes, so your technician will make sure everything meets safety and efficiency standards.

How Is a New Furnace Tested After Installation?

Before wrapping up, the HVAC team will test the system to ensure everything is working correctly. This includes:

  • Checking for gas leaks
  • Testing airflow and temperature output
  • Verifying that the thermostat is properly connected and calibrated

They’ll also walk you through how to use your new system, including any maintenance tips to keep it running efficiently.

What Should You Expect After Furnace Installation?

A professional team won’t leave a mess behind. Expect them to clean up their work area and remove any debris from the installation. Before they go, they’ll answer any last-minute questions and make sure you’re comfortable with your new furnace.
