How Many Hours Does HVAC Installation Take?

A comfortable indoor environment has become a basic necessity due to a significant increase in global warming. Whether upgrading an existing HVAC system or installing it for the first time, a common question that comes to everyone’s mind is: How many hours does it take to install a new HVAC system? The answer isn’t that simple, rather it depends on various factors. In this blog, we will discuss the factors that determine the installation time of HVAC in commercial and residential properties. Curious to know about the hours it takes to install an HVAC system? Let’s dive in!

Factors Affecting HVAC Installation Time

  1. HVAC System Type

The HVAC installation time depends on the type of system you choose. It significantly impacts the installation time. If you prefer a split system, it may take less time as compared to a multi zone ductless system. 

  1. System Size and Capacity

If you have a larger multizone, particularly for commercial premises, it may require more installation time. A system that perfectly fits your property size and possesses the capacity to control temperature ideally may take longer to install. 


  1. Existing HVAC System Removal

If you already have an HVAC system and want to replace it with a new one, it may add up to an extra delay in HVAC installation. The removal process may vary depending on how long the outdated components take to uninstall.

  1. Ductwork Installation or Modification

Ductwork installation requires significant installation time. It becomes more complex when you opt for custom ductwork. Unique layouts or retrofitting of the ducts may increase the overall installation time of your HVAC system.

  1. Location and Accessibility

The location of your HVAC equipment and its accessibility can also impact its installation hours. If the areas where you want to install are hard to reach, the total installation time will automatically increase.

  1. Permits and Regulations

The acquisition of permits and regulations is another important factor that may add to the HVAC installation process. If you own property in NYC, then you may need a permit from DOB (New York City Department of Buildings) and DEP (New York City Department of Environmental Protection). You have both the options of whether to have permits of your own or ask your HVAC contractor to do it for you. Your HVAC contractor may save you time. 

  1. Complexity of the HVAC Installation

Some uncalculated on-spot factors can also impact the installation time of your HVAC. These include multi zone systems, geothermal heat pumps, and uncontrolled factors like weather and delays in the shipment of components or parts you want to install. 

Conclusion To Total Installation Time: 

The total time required for your HVAC installation is the total sum of the abovementioned steps. Since these timeframes can vary based on the specific circumstances, therefore, a professional HVAC contractor can provide a more accurate estimate. These factors will better explain why HVAC installation times vary and how to plan accordingly.
