    This is my third Costway split air conditioner, and each one is in perfect condition. The first two have been in use for a year now, and their cooling and heating performance is excellent.

    Costway 12000 BTU Mini Split AC, 20 SEER2 Ductless Air Conditioner w/Pre-Charged Condenser, 115V Energy Saving AC w/Heat Pump DC Inverter System & Installation Kit

    10/03/2025

    Absolute garbage. It runs our 32 refrigerant, which is absolutely impossible to either buy or get a technician to work on.;With the money I’ve spent on trying to get the refrigerant for this unit, it would’ve been cheaper to throw this thing in the garbage and buy a complete new one.;Additionally, the brand name on the one I got is Cost Way, so just some random unit that was substituted for the one I actually ordered.;Unfortunately for me, I bought it during prime days and stored it for four months before I installed it so I’m stuck with it.
