I just did a DIY install of a mini split AC, including running electrical and the refrigerant lines, having never done so before. There was a whole "hidden side of the iceberg" to learn besides just the controller parts of how it works. The unit cost was ~600 while the install would have been ~1500, so I was betting that if I mess up catastrophically I could replace the whole thing once or even twice.
- zaroth 6y agoWould love to read the write up!
- OnACoffeeBreak 6y agoDid you have to get your work inspected? Where I live in the United States, the electrical lines would have to be inspected for compliance with building code, and I am not sure about the HVAC lines.
- lxe 6y agoElectrical needs a permit, but AC is not a necessity apparently.
- miahi 6y agoDid you use a vacuum pump for the refrigerant lines? If air is still inside the lines, the unit will not last as long - the problem is the trapped moisture that can damage the pump in the long run.
- lxe 6y agoYup. The pump is cheap on amazon and there's youtube videos a-plenty. The mini split AC's come with the refrigerant charge stored in it, so it's crucial to get it properly connected and vaccumed the first time.
