When it’s time to install a new furnace, many homeowners want to know one thing: How long will it take?

Unfortunately, this is not an easy question to answer since the installation time can vary from project to project and depends on a number of factors. However, by understanding what variables can impact the installation time of a new furnace, you can better understand how long your project will take.

General Timeline

In general, a furnace installation should take between four and 10 hours. This is a broad range, but you can expect most projects to fall somewhere within this time frame. In most cases, the entire process is completed within a single day.

The first step of the installation process is removing the old furnace and any other components that will no longer be used. This task includes disconnecting and removing old wiring, fuel lines, and ventilation ducts. Once the technician has removed the old furnace, they will inspect any existing components and insulation to make sure they are in good working order for the new furnace.

Next, the technician will prepare the site for the new furnace. If there is no existing furnace in the home, this will be a more lengthy process because the technician will need to install ventilation ducts, wiring, and fuel lines. In any case, the technician will clean the installation site and measure and inspect the area to ensure adequate space for the new furnace. If the existing furnace was a different size or style than the new one, additional preparation may be needed to accommodate the new model.

Finally, the technician will install the new furnace and connect the wiring, fuel lines, and ventilation ducts. After all components are connected correctly, the technician will test the system to ensure it is operating properly.

Factors That May Impact Installation Time

Several variables can affect how long each step in the installation process takes. For example, if the home has an existing furnace, removing it may take less time than installing a new unit from scratch. However, an existing furnace can also complicate some projects if components must be replaced or the technician must move existing ductwork or wiring. Older homes may also require additional time to prepare the installation site because they often have outdated insulation and ventilation systems requiring updates before the new furnace can be installed.

The size of the unit can also impact installation time, especially when installing a new furnace from scratch. The larger the unit, the more time is needed to measure and prepare the installation site. More components will also need to be connected when installing a larger furnace, which can add even more time.

In some cases, the technician may need to install additional components to the HVAC system for the new furnace to operate properly. These components might include air filtration systems, thermostats, zoning systems, humidification systems, and more. Adding any of these things may increase installation time by several hours.

The technician may also encounter unexpected issues that add to the installation time. They could run across a faulty air filter, poorly insulated walls and ceilings, or obstructions in the ventilation pathways. The technician may also need to access hard-to-reach areas, which could add several hours of work.

It’s also important to consider the technician’s experience and qualifications when estimating installation time. A NATE-certified technician who has experience with furnace installations will likely be able to complete the job faster than someone new to the trade.
