Questions & answers

Before you buy

Everything homeowners ask about installing and sizing a MRCOOL system.

What is included in this set?

This SKU is the matched indoor air handler and outdoor condenser sold together. The listing names both model numbers so you can confirm the pair before you order. Line sets, thermostats, and heat kits are only included when the description says so.

Does this need professional installation?

Central ducted and Olympus (pro mini-split) systems need a licensed HVAC technician. DIY Select and EasyPro complete kits are designed for homeowner installation with the included Quick Connect line set. EPA 608 certification is required to handle refrigerant on pro equipment.

What size do I need?

Sizing depends on square footage, insulation, climate and duct or zone design. The rated capacity is in the specifications. Our team can help you confirm the match.

Does installation affect the warranty?

Register the system after installation to activate the factory warranty. Improper installation is a common reason claims get denied.
