Portable air conditioners typically last 5–10 years, but proper maintenance can extend their lifespan by up to five years. Factors that can affect a portable air conditioner's lifespan include:
Usage: The more you use your air conditioner, the more maintenance it needs.
Placement: Improper installation can cause parts to overheat or strain.
Environment: Salty air, poor air quality, and high humidity can shorten the life of your air conditioner.
