What precautions need to be taken with packaged AC systems that have ductwork installed outside?

The requirement for insulation and weatherproofing of ductwork in packaged AC systems installed outside is essential to ensure efficient operation and protect the system from environmental factors.

Insulation is critical because it helps to maintain the temperature of the air moving through the ducts. When ductwork is exposed to outdoor temperatures, uninsulated ducts can lead to significant energy losses, impacting the overall efficiency of the air conditioning system. Proper insulation can prevent the condensation of moisture on the outer surface of the ducts, which can lead to mold growth and structural damage.

Weatherproofing is equally important as it protects the ductwork from rain, snow, and other elements that could potentially compromise its integrity. Additionally, adequate weatherproofing can help guard against pests and related infestations, which can be common issues with exposed ductwork.

Together, insulation and weatherproofing play a vital role in maximizing the performance and lifespan of outdoor duct systems in packaged air conditioning applications.
