After purchasing a new HVAC unit, professional technicians will come to your home to perform the installation process. It’s important that you’re present as they may have questions. There are also specific steps you can take to prepare the space. Here is what you can expect when you have your HVAC unit replaced.
The Length of Time for the Installation
Although the average time it takes to install an HVAC unit is about one day, the time can vary depending on different factors. These factors include the size of your unit, the type, and if there are ductwork modifications that need to be performed. Sometimes, there may be unforeseen issues that pop up that can lengthen the installation process. If you have a condo or a small home, technicians can install your HVAC unit in roughly four hours. Commercial HVAC units, on the other hand, tend to take longer to install. The installation process for these units can be a couple of days, especially if customizations are necessary.
Preparing the Area for the HVAC Unit
Many homeowners think that the HVAC unit is simply placed where the old one was. However, the area must be prepared first – by you and then by the technicians. Before technicians arrive, remove any valuable objects that you don’t want to be broken. If you have pets, make sure to keep them in another room or area of the house. Once technicians arrive, they will clear the work area, removing any items or debris that could get in the way of the job. They will also lay out material to protect surfaces, such as the floors and walls. Many technicians use large plastic sheets or drop cloths. This can help protect your furnishings, floors, and walls from marks or scratches. Technicians must also inspect the area to see if any modifications are needed.
Removing Your Old HVAC Unit
Professional technicians typically follow a checklist when they remove your old HVAC system. They first make an initial assessment to determine what needs to be removed and disposed of. Then they turn off the power. If your HVAC system is powered by gas, technicians will shut off the gas as well. Next, they will disconnect the wiring and plumbing connections. If there is refrigerant in the HVAC unit, technicians will safely remove and dispose of the refrigerant. Most HVAC companies use special equipment to capture all the refrigerant in the old HVAC unit. If the unit can’t be removed in its entirety, technicians will have to disassemble the components and remove them one by one. Finally, they will remove the unit from its location so the new unit can be installed.
Modifying or Installing New Ductwork
If you have had your HVAC system for a while, your ductwork may be worn out, damaged, or old. Technicians will inspect your existing ductwork to determine if you need new ducts or if you can modify your old ones. Ductwork directly impacts the airflow in your home, so technicians will need to calculate the airflow requirements. This information will allow them to determine if your ductwork can accommodate your new HVAC system. If you need new ducts, technicians may add ducts, reshape the old ones, or adjust their sizes. They may also have to adjust the layout to create a balanced airflow. After installing new ductwork or modifying existing ductwork, technicians will ensure your ductwork is well insulated.
Installing Your New HVAC Unit
Once your old unit has been removed and your ductwork is ready to receive the new HVAC unit, technicians will place the new unit into its proper installation site. Once positioned, they will use supports and hardware to secure it correctly. Next, they will connect all the electrical wiring and the plumbing. They will also connect the refrigerant lines and the drainage lines. Drainage lines are necessary as proper drainage will prevent water from building up in your HVAC system. The final step in the installation process is to connect the ductwork to your HVAC unit.
Testing the New System
Although the installation process seems to be complete, there is one final step. Technicians must test your HVAC system to ensure it works. They will check all the electrical connections, test the refrigerant levels, ensure there is proper airflow, and more. The unit should operate according to the manufacturer’s specifications. Most setup procedures call for a startup process and a calibration process. During these two stages, technicians will program the thermostat and fine-tune the temperature settings. Once the HVAC unit is up and running, technicians will clean up the area, removing any debris.
