Before You Order

Make sure it is the right size, and that you have the rest of it

Most outdoor units ship alone. If you are not certain of the capacity, or of what has to go with this unit, these two will work it out with you.

System Finder Draw your space in 3D and get a capacity range, with equipment that fits it. Takes about a minute. Size it in 3D → Complete System Builder Start from the outdoor unit. Only the coil, air handler, heat kit, line set and thermostat matched to it are ever offered. Build a system →
