Questions & answers

Before you buy

Everything homeowners ask about installing and sizing a MRCOOL system.

Can I DIY the install?

Yes. MRCOOL DIY systems ship with pre-charged QuickConnect line sets, so there is no refrigerant handling, no vacuum pump and no special tools. The MRCOOL app walks you through each step, and most homeowners finish a single-zone install in an afternoon.

What tools do I need?

A drill with a hole saw, a level, two wrenches and basic hand tools. The line set connects by hand and tightens with wrenches, and the mounting hardware is included.

Is a permit required?

Rules vary by county. Many areas allow a homeowner install with a simple permit, though the dedicated electrical circuit often needs a licensed electrician. Check your local code before you start.

What size do I need?

Match the BTU rating to the room you are conditioning. This listing shows its rated coverage in the specifications, and our system finder can size a room in about a minute.
