What Goes On During HVAC Installation?

Your home’s HVAC system is not just a single unit that slides into place and begins operating to cool your home. Instead, it’s a set of intricate parts that all have to work together to operate efficiently and effectively.

If you anticipate having a new HVAC system installed in the near future, you may be wondering exactly what happens during the installation process. 

We are here to answer your questions as the experts at HVAC installation in Puyallup, WA. We know that HVAC installation is a major project for your home and your wallet. You want to know exactly what is going to happen from start to finish. Keep reading to learn more about the details of HVAC installation so you know what to expect. 

Initial Evaluation

Before we ever begin the installation process, our team visits your house for an initial assessment. We want to look at your existing HVAC unit to see what all needs to be done for removal in preparation for the installation. If there are connections and components that we can keep in place for your new unit, we will do so to save you money. However, if there are components that are outdated or significantly worn out, we’ll replace those to optimize your new system. 

Taking Out Your Old Unit

On installation day, our team will first begin to lay drop cloths around your home in areas where we want to protect the walls and floors. These may be around your indoor air conditioning unit, as well as near the air intake and vents in your home.

We’ll turn off any energy sources that lead to your HVAC system, including gas and electricity lines. Then, we’ll begin to carefully take apart your existing HVAC system and remove all of the components. 

After that, we’ll clean up and check all of the existing connections to see what needs to be replaced in preparation for your new unit. We want to make sure that your new HVAC unit has a sturdy foundation to sit on. We may have to add extra dirt or level the foundation for the outdoor portion of your unit.

Installing the New Unit

Once we are through removing all of your existing HVAC components, we begin installing your new air conditioner. Everything will be fitted with new lines and service valves. Our team will make sure that everything is leak free, and completely secure. 

If we’re using existing ductwork, we’ll make sure that all those seals are secure so that the air ducts leading to your vents are airtight. If there are any air vents in awkward locations in your home, we can relocate those to more convenient places as part of our installation process. These are all things that we will talk to you about during that initial evaluation so you will know what to expect in advance.


Once your new unit is in place, we’ll run a series of diagnostic tests to make sure that everything is working as it should. If we need to make adjustments along the way, we can do this throughout the testing process.

Then, we can teach you how to operate your new HVAC system. While it’s likely very similar to your previous unit, each system is unique and may have certain nuances that you need to know about. We can even make suggestions for how to ensure that your HVAC system is always operating efficiently by helping you to optimize your heating and cooling settings.
