Reliable, efficient—highly recommended
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.

Working very well
I waited a few months to give our unit a good run. I have been very impressed. It's quiet, cools well and heats well. We have a well insulated Barndominium that I built and it has performed excellent. Today, 01/26/2026 it is 15 degrees with a wind chill below zero and it's doing great. 1600 square ft and our only heat source at the moment. Our unit is in the living area with a vaulted ceiling, using ceiling fan to circulate air and a stand fan to blow air into rooms.

Are these units pre charged? I installed one for a customer but it is not getting cold. The compressor is trying to kick in but it’s not cooling the air.
A:
Yes, the unit is pre-charged with refrigerant for standard installation. If the compressor is attempting to kick in but the unit is not cooling, please check the following troubleshooting steps: 1. Ensure that the installation method is correct and that the unit is properly vented to the outside. 2. Confirm that the ambient temperature is suitable for cooling and that the set temperature is lower than the ambient temperature. 3. Check for any loose connections or leaks in the refrigerant lines. 4. Observe if there are any error codes displayed on the unit. If the issue persists, it may require professional assistance to diagnose and resolve the problem.
