Most of us are familiar with what happens when your air conditioner goes out: you call a company to perform basic HVAC services and get it running again. But what happens when your furnace quits entirely or if you're replacing your old one with a new one to take advantage of energy-saving features? Since furnaces last between 18-20 years, you may not have experienced a furnace installation in a while (and it will hopefully be a while before you experience it again), so it's good to know what's involved in the process.
Remove the Old Furnace
This part should go without saying, but they won't be able to install a new furnace without removing the old one first. In some circumstances, this can be the longest part of the job, since they'll have to move items out of the way, find and remove the existing connections, and find a way to lift it out of its current position. Several things can go wrong or happen unexpectedly during this part, so most technicians take their time with this step.
Prepare the Space
Once the old furnace is gone, one or two team members will start to prepare the space for the new furnace installation. That may consist of cleaning the floor, attaching new and updated connection points, or adding reinforcement to the spot if it's been structurally compromised.
Install the New Furnace
After the area is prepared, the technicians will carry the new furnace to its permanent location, install it, and attach all of the connection points (of which there are many). They may even take the opportunity to perform basic heating maintenance on your new unit by cleaning the ductwork or shifting it around to better protect it. If your furnace is gas powered, it'll take longer to finish this step since handling gas lines has to be done with extreme caution. Regardless, once it's hooked up to the power source, the job is almost complete.
Test the Unit
Before the team leaves, they should spend time testing the furnace to make sure the installation went as planned. They'll measure the air intake and airflow at different spots throughout the house and make sure that it's blowing evenly. If the furnace is operating correctly, they'll double check for any possible safety hazards and run through the new system with the homeowner. Only after everything has been checked out thoroughly will the team consider their furnace installation complete.
