Effective for large rooms, but electrical work needs a pro

This unit performs well in a 540-square-foot kitchen and living area, and with a fan directing air into a bedroom, it also helps there. Installation is doable as a DIY project except for the electrical hookup, which requires a professional. Having a friend who installs HVAC made the electrical work affordable. It is advisable to price out the electrical portion before buying to understand the total cost.

Pros
  • + works well in a 540 sq ft kitchen/living area
  • + can help cool a bedroom when a fan is used to direct air
Cons
  • − electrical hookup requires a professional, not DIY

Warranty Denied After Freon Line Weld Failure

The freon line broke cleanly at a weld point with minimal stress during outdoor placement. A photo shows no kink, crimp, twist, or deformation, and the break appears consistent with thermal embrittlement from overheating during welding. The warranty claim was denied, with the company stating the break was not at the actual weld point and blaming mishandling. The denial is seen as contradicting the photo evidence and facts. The product is not recommended due to the lack of warranty support.

Cons
  • − Freon line broke at a weld point
  • − Warranty claim denied
  • − Company blamed mishandling despite photo evidence
