Here is how to install rooftop AC step by step:
First, clean the roof and make sure the area is flat and strong enough to hold the AC unit. Check for any obstacles or weak spots.
Construct a platform to hold the AC unit. Make sure it is level and strong. Secure it with screws so it does not move.
Measure and connect all ducts to the platform. Divide the airflow correctly to all rooms. Strap and secure all ducts tightly to prevent leaks.
Cover the ducts with insulation. You can double up for better protection. Insulation keeps the system airtight, reduces noise, and protects from water leaks.
Place a gasket or seal on the top of the platform. This ensures everything is airtight and prevents any air or water from escaping.
Carefully place the rooftop AC unit on the platform. Align it properly and secure it to the platform with screws. Check that it is stable and level.
Connect the power supply and any fans, such as bathroom fans or attic fans. Make sure all electrical connections are safe and follow code.
Turn on the system and check the airflow and cooling. Make sure all ducts are properly connected, and the unit runs quietly.
Cover the platform and ducts with any additional insulation if needed. Check for leaks or vibrations. Once everything works, complete the roofing around the unit.
Finally, inspect the whole unit. Confirm the AC is secure, ducts are airtight, and the airflow is correct. Your rooftop AC installation is now complete.
I hope you now clearly understand the step-by-step process to install a roof-mounted air conditioner.
