How Long Does It Take to Install an HVAC System?

There’s no need to be miserable in your own home! Don’t delay when you think it’s time for a new HVAC system.

So you may be asking how long does it take to install an HVAC system? The timeframe can vary depending on the size of your home or building, the type of installation, the kind of unit, and the installation area.

Once an HVAC contractor does an assessment, they should be able to give you an accurate timeframe. If you’re planning to install a furnace or air conditioning system, we can help!

Below is everything you need to know about the installation process and the time it takes.

The Size of Your Home

The most significant factor affecting installation time is your home’s size. Bigger homes may require larger units or possibly multiple units.

Generally, the larger the home or building, the longer the installation process will become.

HVAC Replacement

When you install a new HVAC system and the old equipment is still functional, that’s called a system change out. If you need a system change out, the timeframe for installation would be shorter than if you were starting from scratch.

A system change out would take between 8 and 14 hours, whereas a new installation in a newly built home will take a lot longer. It all depends on the type of system you’re having installed and how much has already been done.

Full HVAC System Installation

Installing an entire HVAC system will take longer than a simple change out. Typically, a full HVAC installation takes 3 to 5 days to complete.

Full system installations may require replacing the duct system, rewiring the thermostat, and various other components depending on the system. This means that the process may take more time because the process can be a lot more complicated.

Location of Unit

It’s not just the type of system that affects the installation time. The unit location also makes a difference.

If you live in a building or condominium with a high roof, you can expect some additional time added to the timeframe. If a crane is needed, the installation becomes more technical and time-consuming.

More complex installations may require more technicians. The team will need to be well-coordinated to avoid any delays.

Preparing for Installation

The HVAC contractor will need some time to assess your home and determine the best AC unit for you. They’ll also need to develop a plan for the installation, which includes preparing the area where the unit will be installed. 

This may require removing existing AC units, rerouting ductwork, or making other preparations. All of this will need to be factored into the installation time.

After everything has been planned and prepared, the actual installation process can begin!
