Exceeded expectations for the price
03/16/2026After extensive research, I chose this model for its balance of price, efficiency, and cold-weather heating capability. It cools and heats my 650 sq.ft. apartment quickly and evenly. The fan is so quiet on the low setting we can barely hear it. The build quality feels solid. For the money, you simply cannot beat this unit.

Man Cave Vitals
09/18/2025Purchased the split unit to go onto me office in my metal barn. Heating used to be a kerosene heater or a small space heater, both took up needed floor space. As for A/C, doors open or closed and a fan. This unit mounted high on the wall has kept the office at 73°F with no problem at all and nothing to trip over. Also it's quieter than the refrigerator I have in there as well. Got the idea from my sister and her two units in Pennsylvania. The only outside help I needed was getting someone with the correct plumbing fittings to evacuate the copper lines between the indoor and outdoor units. Went together just like the manual said it would. I poured the cement pad and welded the rack so the outdoor unit wouldn't sit in the soft ground behind the barn. No trouble there, probably overkill but it makes me feel better.

Q&A
- Q:Is this an inverter AcA:It has a full dc inverter.
Costway representative - Q:What is the exterior cold ratingA:The exterior cold rating for the unit allows it to operate in a temperature range of 14 to 122 degrees Fahrenheit. However, for heating, the lowest outdoor temperature it can effectively operate at is -7 degrees Celsius (approximately 19.4 degrees Fahrenheit) before performance begins to decline.
Costway representative - Q:How high off of the floor does the indoor unit have to be installed?A:The indoor unit should be installed with a minimum space of 7.5 feet from the floor to ensure proper functioning. However, it is recommended to leave at least 6 inches from the ceiling for optimal performance.
Costway representative - Q:Is the QMID 17W zero or the letter O?A:It is I7W0 — starting with a capital “I” (not the number 1) and ending with the number “0” (not the letter O).
Costway representative - Q:What is max length of line for this 12000 230 v unitA:The maximum effective operating distance between the indoor unit and the outdoor unit is 50 ft. Please note: If the pipe length exceeds 24.6 ft, additional refrigerant is required in proportion.

Costway representative - Q:What is the max line set length to stay within the pre-charged requirements?A:The maximum line set length for the unit to stay within the pre-charged requirements is 13 feet. If you need to extend beyond this length, additional refrigerant will be required to ensure proper operation.
Costway representative - Q:What size breaker do you need to get power to the unit when installing a 12000A:For the 12000 BTU unit , you will need a 16A circuit breaker to provide power during installation.
Costway representative - Q:What is the lowest temperature that it still heats effectivelyA:It will not work well when the temperature is lower than -7℃.
Costway representative - Q:How low an outside temperature does it workA:The item can operate in an ambient temperature range of -15°C to 52°C. However, it works normally between -5°C and 42°C, and its cooling and heating effects may diminish when the temperature is between -15°C and 60°C.
