I bought a Perfect Aire Mini-Split system, the Outdoor unit defected out of the box - no refrigerant gas flow sound when the refrigerant valves are opened. Fan is not spinning when commissioning the system. The manufacturer Perfect Aire refused to replace the whole Outdoor unit, but they offered to send an internal electronic circuit board so that you can find a local HVAC expert to repair on your own cost, and no guaranty for a fix. Or send them the defected unit to be troubleshooted by their technicians and they may or may not return the functional unit based on their terms. So Don't trust Perfect Aire's No-hassle 1-Year Warranty, And Don't buy any Perfect Aire products all together if you don't want any headaches.
