Furnace Installation Step-by-Step

Furnace installation can be a complex and involved process, but with the right knowledge and preparation, it can be a smooth and successful experience. Here is a step-by-step guide to everything that happens during the installation of a new furnace so you know exactly what to expect.

1. Planning and Preparation

Before the installation process begins, it is important to properly plan and prepare for the installation by working with a licensed HVAC contractor. Your contractor will help you select the right size and type of furnace for your home, order equipment if needed, schedule a date to complete your furnace installation, and secure any necessary permits and inspections. They’ll help you decide whether a gas furnace or an electric furnace would be best for your home. Make sure when considering companies to install your new HVAC system, that you get recommendations from friends and neighbors, look at reviews for companies you’re considering, and get a few quotes to make you feel confident in your choice. 

2. Removing the Old Furnace

If you are replacing an existing furnace unit, the first step in the installation process is to remove the old furnace. This may involve disconnecting gas and electrical connections, removing the old furnace equipment from its location, and properly disposing of it. The area is cleaned and prepped to make way for the new furnace installation if the same location will be used.

3. Installing the New Furnace

Once the old furnace has been removed, the new furnace can be installed. This typically involves mounting the furnace to the wall or floor, connecting it to gas and electrical lines, and setting up the system. If you’re switching to a gas furnace, you may need gas lines run into your home. 

4. Ductwork Installation

A furnace is only as effective as the ductwork that distributes the warm air throughout your home. If your home does not have existing ductwork or if the existing ductwork is in poor condition, it may be necessary to install new ductwork. Old ducts are removed if applicable, the new duct system is installed, and then the new furnace is connected to the supply and return plenums. Leaky, old ducts can cause a loss of heated air which can make your energy bills soar. Make sure that every part of your HVAC system works efficiently so your new system helped you save money instead of wasting it. 

5. Final Testing and Commissioning

Once the furnace and ductwork have been installed, it is important to conduct final testing to ensure that everything is working properly. A combustion analysis is completed to ensure that the furnace is burning fuel efficiently and safely, and the combustion components are adjusted as needed to optimize performance. We measure static pressure, airflow, and temperature rise to ensure the new unit has proper airflow and functions correctly.

Maximize the Value of Your Furnace Installation

There are several measures homeowners can take to ensure that their new furnace installation lasts as long as possible, starting prior to installation and continuing during the unit’s service life:

  • Choose the right size furnace: It is important to choose the right furnace that is properly sized for your home. If the furnace is too small, it will have to work harder to heat your home, which can lead to premature wear and tear. If the furnace is too large, it will cycle on and off more frequently, which can also lead to premature wear and tear.
  • Have furnace installation performed by a pro: It is important to follow the manufacturer’s recommendations for installation; failing to follow these recommendations can void the manufacturer’s warranty and may also reduce the lifespan of the furnace. A professional furnace installer has the knowledge, experience, and tools to properly install your furnace according to the manufacturer’s recommendations.
  • Properly maintain the furnace: Regular maintenance is key to ensuring that your furnace lasts as long as possible. This involves cleaning or replacing the air filter regularly and having the furnace professionally inspected and serviced on an annual basis.
  • Address any issues promptly: If you notice any issues with your furnace over the years, it is important to address them promptly. Ignoring issues can lead to further damage and may shorten the lifespan of your furnace.
