MRCOOL HVAC

MRCOOL's warranty terms depend on registration and on who opened the refrigerant circuit, and a self-installed unit can have different coverage than a professionally installed one. We work within the manufacturer's terms where they apply. Any repair work we perform carries our own 1-year workmanship warranty, and a new system we install is Mitsubishi Electric, registered for the Mitsubishi Electric limited warranty.

MRCOOL's warranty depends on registration and on who opened the refrigerant circuit, and a self-installed unit can carry different coverage than a professional install. We work within the manufacturer's terms where they apply, and the brand's parts network is thinner than the lines we install, so lead times can run longer. Our own repair work carries a 1-year workmanship warranty.

Depends on what is causing it. If the room was added after the central system was sized, a dedicated ductless head is often the cleaner, cheaper fix. If the central equipment is undersized or aging, supplementing it with a band-aid just defers a replacement. We re-run the load and tell you which one your house actually needs.

The MRCOOL warranty is between you and the manufacturer based on the unit you registered, not us. We can document repairs we perform on an existing system, but the manufacturer decides coverage. We cannot extend our own install warranty to equipment we did not supply. If we replace it with a Mitsubishi Electric system we install, we register it for the Mitsubishi Electric limited warranty.
