Sealing the exterior of a HVAC wall unit can be a do-it-yourself project for those with basic handyman skills. However, it is important to note that improper sealing can lead to potential damage to the unit or the building’s structure, as well as voiding manufacturer warranties.
If you are unsure about performing the sealing yourself, it is recommended to consult with a professional HVAC technician or contractor. They have the expertise and experience to ensure proper sealing that is in line with the manufacturer’s guidelines.
Sealing the exterior of a HVAC wall unit can bring numerous benefits, including improved energy efficiency, increased comfort, and protection against moisture and air infiltration. While it is possible to seal the unit yourself, it is important to exercise caution and follow proper guidelines to avoid any potential harm. Consulting with a professional HVAC technician is always a wise decision to ensure the job is done correctly and to maintain the integrity of the unit.
