Manufacturer Warranty
Covered by MRCOOL's limited warranty. Warranty terms are set by MRCOOL and differ by product line — whether registration is required, and whether the installation has to be performed by a state-licensed HVAC contractor, is not the same across the range. In every case coverage depends on the unit being installed according to MRCOOL's instructions and all applicable codes and permits. MRCOOL's warranty document for this model is the controlling source; ask us and we'll send you the one that applies.
Professional Installation Recommended
Most HVAC equipment must be installed and connected by a licensed professional to remain safe, code-compliant, and eligible for manufacturer warranty coverage. If you're unsure about installation requirements, contact us 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.
