How Long Does It Take to Install a New HVAC System?

The average time it takes to install a new HVAC system is eight to 14 hours. A technician will likely spread the work out over three days. While it takes a technician four to eight hours, on average, to install a brand new air conditioning unit and four to 10 hours for a new furnace installation, that’s just an estimate. When you’re replacing both, you can expect it to take twice as long, but other factors can impact the time for installation

Timely Tasks

During a full HVAC replacement, your technician has to replace your heating, ventilation, and air conditioning — this takes time! HVAC replacement can call for eight to 14 hours of your technician’s time and effort, and there are a few factors that can impact that estimate.

The Size of Your Home

When tackling a full HVAC replacement, remember: the larger the space, the longer it takes. This is because larger spaces are more difficult to heat and cool, so the systems that manage them need to be larger to handle the job. Bigger spaces often require either larger HVAC units or more than one HVAC unit.

Are You Replacing or Installing a New System?

You know the size, brand, color, and style of your favorite pair of pants. So when looking for a new pair, it takes less time to find what you want. The same goes for your HVAC system. When swapping out an old unit for a new one takes a lot less time than installing a brand new system since the return and supply ductwork is already in place.

Location of the Installation

Depending on the location of the system you’re replacing, your installation may take longer. For example, if your unit is hard to reach, hidden away, or high up (like on a rooftop), it can be a more difficult installation that calls for more time and resources to complete the job.
