Step-By-Step Furnace Installation: What To Expect

by Louise Moore

If you are in need of a new furnace, you may be wondering how the HVAC contractor or technician handles the job. You may also be wondering if you should take the day off from work and/or how long the job will take. The following shows a step-by-step furnace installation so you know exactly what to expect when the contractor or technician shows up.

Step 1: Unbolting the Old Furnace from the Floor

Your old furnace probably has been bolted to the floor to secure it and keep it in place when it runs. The technician will look for the bolts that hold the main part of the furnace in place and unscrew them. Before he or she can remove the furnace, the next steps have to be completed as well.

Step 2: Detaching all of the Electrical Wiring

Regardless of the type of furnace you currently have (e.g., boiler, gas or electric), there will still be some electrical wiring that needs to be detached. The technician will have to switch off the power that runs to the furnace, and may even switch the main breaker to ensure personal safety during this process. If you are working from home, you may want to make sure your laptop or tablet is fully charged or you will not be able to work during this time. Otherwise, take at least half a day off from work while your old furnace is removed and the new one is installed.

Step 3: Detaching All of the Vents and Fuel Lines

Next, the technician will detach the furnace from all of the vents that lead up into your home. If your furnace also runs on oil, natural gas or propane, the furnace needs to be detached from these as well. All fuel lines should be shut off and/or closed off during this step. Now that the old furnace has been completely detached from everything that holds it in place and made it run, it can be safely removed.

Step 4: Removing the Old Furnace

The old furnace may be lifted onto a dolly and removed, although your technician might take the furnace apart a little more and haul it out in pieces if the whole thing is too heavy or cannot be carried out the door in one piece. Your technician may call for backup at this point if he or she does not already have an assistant or fellow technician standing by. Now the new furnace can be installed.

Step 5: Installing the New Furnace

So long as you are not converting from one type of furnace to another (e.g., electric only to gas), the new furnace installation is relatively easy. The technician just reverses the steps taken to remove the old furnace. He or she may test it before leaving your home by turning on the thermostat and setting it to a certain temperature and then tweak it if anything does not seem right. Then your new furnace is ready to go.

About Me

Learning About Old and New Furnace Options

Hi there, my name is Marissa Sonder. I would like to use my site to talk about the different types of furnaces available for residential and commercial applications. Growing up, my school had an actual boiler room that provided heat and hot water for the entire building. All of the students loved to go down to the boiler room and learn about all of the components down there. Although many buildings have moved on from this old piece of equipment, I would like to discuss its use in detail on this site. I will also talk about modern electric, natural gas, propane and oil furnace systems. Thanks for coming by.
