What it concludes
- Buying a mini-split directly from the manufacturer website can save more money than buying from Amazon, while still offering free shipping.
- Using a 2-1/8 inch or slightly larger hole saw is ideal for drilling the wall penetration for the line set.
- A 5 CFM vacuum pump costs approximately $116 and saves hundreds of dollars compared to professional installation.
- A non-fused A/C disconnect is recommended because a fuse is not needed when a circuit breaker is already present at the other end of the line.
- A 3/4 inch power whip can be difficult to fit in the knockout and a 1/2 inch power whip is recommended instead.
