Our take on the Costway Blast Series 19 SEER2 Mini Split Air Conditioner with Heat Pump

The Costway Blast Series is an 18,000 BTU ductless mini split with a heat pump, rated 19 SEER2, and Costway says it covers up to 1,250 square feet. It includes a remote, sleep mode and heating down to cold outdoor temperatures, so one unit handles both summer cooling and winter warmth. It sits at the budget end of the mini split market, where brands like Pioneer and MRCOOL offer similar capacity with longer track records and wider installer support. Buyers who want a low-cost single-zone system and can arrange their own installation are the main audience; owners report it works well once properly installed, but some run into setup and support problems.

Questions and answers

Is 18,000 BTU enough for my room?
Costway rates it for up to 1,250 square feet, which fits a large living room or open plan. Rooms with heavy sun, poor insulation or high ceilings may need more capacity.
Does it heat as well as it cools?
It is a heat pump, so it provides both. Heating output drops in very cold weather, so in harsh climates expect it to work best as a supplement to another heat source.
Can I install it myself?
The electrical and refrigerant work usually requires a licensed technician with gauges and a vacuum pump. Many buyers hire an installer and handle only the mounting and prep themselves.
How does it compare with Pioneer or MRCOOL?
Those brands have longer track records and broader parts and technician support. Costway competes on features per dollar, but reliability and service are the trade-offs.
What comes in the box?
The indoor and outdoor units, remote control and basic mounting hardware are included. Line sets, wiring and mounting brackets are often bought separately, so check before ordering.
Does it work with a smart thermostat or app?
Control is through the included remote, with sleep mode and standard modes. There is no built-in Wi-Fi app control, so smart integration needs a separate controller.
