HVAC installation can seem like a disruptive or daunting task. There are so many things to consider when choosing and installing a new HVAC system. What can you expect during the process? How long will it take? And what should you do to prepare for installation day?
In this article, we’ll answer these questions and more. We’ll walk you through the HVAC installation process step-by-step, and we’ll give you some tips on how to make it go as smoothly as possible.
Note: The process outlined in this post is what we follow, and other HVAC contractors may do it differently.

Here’s what to expect from your HVAC unit installation.
The HVAC installation team will arrive from 7:30 to 8 am on the day of your installation. They’ll be carrying all the necessary tools and equipment to get the job done.
Your team will typically be made up of 3 to 4 technicians and/or engineers. Each will have a specific job, such as measuring and cleaning. They’ll work together to get the job done as quickly and efficiently as possible.
The HVAC installation technicians will start by “recovering” or removing the old refrigerant from the outside unit. This is done by recovering it into industry-standard containers. This ensures that the old refrigerant is disposed of safely and properly. Brand new refrigerant will come with your new unit.
If a technician doesn’t properly drain the refrigerant, it can spill and cause problems. Spilled refrigerant is a biohazard that can harm the environment.
It’s important to make sure that the technicians know how to properly drain the refrigerant before starting the installation. That’s why working with an experienced and certified HVAC contractor is so important.
While the refrigerant is being removed outside, a couple of engineers will head inside to scope out your home’s space and ductwork.
Your HVAC technician will need to measure the space where your new unit will be installed. This is done to make sure that the unit can fit properly and that there are no obstacles in the way.
If you’re considering moving your HVAC system to a new location in your home, it’s important to discuss the move with your HVAC contractor beforehand.
Some HVAC systems can be moved a few inches, while others may need to be relocated to another room in the house. It’s important for the technicians to measure and plan for the move before starting the installation.
Talk to your contractor about your options before the installation. They may be able to give you some ideas on how to make the move possible.
Once the technicians have finished removing the old refrigerant, they’ll uninstall the old HVAC unit.
This process is usually quite straightforward. The technicians will disconnect the unit from the ductwork and remove it from your home.
They’ll then carry the new HVAC unit into your home and set it up in the same spot as the old one or a different place if specified beforehand.
It’s important to note that not all HVAC units are created equal. Your new unit will not look exactly the same as the old one and may have a different look and control panel. Some may be a little bit heavier than others.
These changes in specifications are expected but can also cause complications in the moving and installation.
Anyone who’s ever gotten rid of an old couch and bought a new one will understand the struggle and complications with space and size. When it comes to HVAC installation, moving an old unit to a new spot in your home can require as much jostling as replacing a couch.
The process of connecting the new HVAC unit to your current ductwork is often the trickiest part of the installation process.
This is because it can be difficult to match the new unit up with the old ductwork. They begin adjusting your ductwork to make sure your new setup will function properly. If the ductwork is too long or too short by inches, your new unit will not be able to connect with the already existing ducts.
If needed, the team will make any necessary adjustments or send them back to their shop or another supply shop to fabricate the needed materials, so the “tie-in” or ductwork connection is ready.
It’s important to have a qualified technician or engineer do this part of the installation. They’ll have the experience and knowledge necessary to make the connections properly and ensure that your HVAC unit works correctly.
Any time a refrigerant system is opened to the elements, air, moisture, dirt, and dust can get inside. This is very damaging to an HVAC unit. That’s why your techs should evacuate or flush the system before flowing in the new refrigerant.
This can take anywhere from 30 minutes to over an hour. This time can be used to tidy up the job site of any packaging or debris.
You made it to the most important step!
Your HVAC technician will start up your new unit and test it to make sure it’s working properly. They’re inspecting it and making adjustments to make sure your new unit is running efficiently for your home. Airflow connection and strength are tested.
Unfortunately, this is also the step where manufacturing defects are discovered. If there are any problems with the unit, the technician will troubleshoot and fix them.
Once the unit is running smoothly, the technician will give you a brief overview of how to use it. They may also give you some tips on how to keep it running efficiently. Then they will head out around 3 or 4 PM leaving you with your brand new unit!
All in all, an HVAC unit installation typically takes about 7 to 8 hours.
Homeowners often ask about what they should or shouldn’t do before and during an HVAC installation. Here are a few catch-all few tips to help you prepare and to make the process go more smoothly:
