Panic can quickly set in when your furnace breaks down in the middle of the winter. How long does it take to replace a furnace? is the first question that homeowners ask. Nobody wants to wait for the heat to return on chilly nights  after all.

We at MileHi HVAC understand that when it comes to comfortable heating, timing is of the essence. Knowing the furnace installation time, important aspects and what to anticipate during replacement will help you prepare with confidence, regardless of whether your system has broken down or you’re just upgrading to a more efficient model.

To help you understand how long it takes to replace a furnace, let’s dissect each step of the procedure. 

Average Time Of Furnace Replacement 

It takes four to ten hours to replace a typical gas or electric furnace in most homes. This includes taking down the old unit, setting up the installation space, connecting the new system  and conducting performance and safety tests. 

However a number of factors  like the size of your home, the state of the ductwork and the type of furnace being installed can either shorten or lengthen furnace installation time.The procedure can take up to two full days in more complicated setups.

Step-by-Step Overview of the Furnace Replacement Process 

Knowing what actually occurs during installation is helpful in determining how long  to replace a furnace. The key phases are broken down as follows:

1. System Setup 

Technicians evaluate the heating requirements of your house, examine your current unit and confirm compatibility before beginning the replacement. Usually this phase takes 30 to 60 minutes. 

2. Removing the Old Furnace 

Depending on accessibility, it may take one to two hours to safely unhook and remove the old unit. Dismantling older systems or small basements may take more time. 

3. Setting Up the Site 

The area is cleaned, the venting system is examined and any leaks or obstructions in the ducting are checked by technicians. By doing this, you can make sure that  your new furnace installation time won’t be wasted on correcting problems that could have been prevented.

4. Setting Up the New Furnace 

This can take three to six hours and is the primary phase. To make sure everything works effectively and safely the crew connects gas lines, vents, drainage systems and electrical wiring. 

5. Final Inspection and Testing 

Technicians check the system for proper airflow, thermostat calibration and energy efficiency after installation. Usually, this last phase takes 30 to 60 minutes.

Factors Affecting Furnace Replacement Time 

How long it takes to replace a furnace depends on a number of factors. You can improve your planning and prevent unforeseen delays by being aware of these.

1. Furnace Type 

Because appropriate gas line connections and venting inspections are required, gas furnaces typically take longer to install than electric models. High-efficiency systems might need more exhaust pipes and condensation drains. 

2. Accessibility and Home Design 

It will take longer to access and install your furnace if it is hidden in a crawl space or basement corner. The new furnace installation time typically  decreased in accessible locations.

3. Condition of Ductwork 

Ducts that are outdated or damaged can cause delays. It will take many hours to replace your ducts if they need to be repaired or sealed. 

4. Gas and Electrical Connections 

The furnace installation time  may increase by one to three hours if current gas lines or electrical panels need to be replaced or modified. These procedures are never hurried because MileHi HVAC places a high premium on safety.

5. Capacity and Size of Furnaces 

More testing and setup are needed for larger, more potent furnaces. Additional ductwork or venting modifications may be required if you’re upgrading to a higher-capacity machine. 

Preparation For Furnace Replacement 

The installation might go more quickly and smoothly if you prepare a little. Before your technicians arrive, consider the following brief advice: 

• Clear the work area: Take out any furniture or boxes that are close to the furnace. 

• Make it simple to access: Verify that driveways, entrances, and hallways are free of obstructions. 

• Verify electrical access by making sure power sources are accessible. 

• Keep kids and dogs away to ensure efficiency and safety during installation.
