The MRCOOL Olympus 4th Gen Air Handlers are designed for ducted installation and require a licensed HVAC professional for proper setup to ensure warranty validity and optimal performance.

Coverage areas vary by model. For example, the 9k BTU unit covers up to 400 sq ft, the 12k BTU up to 600 sq ft, the 18k BTU up to 800 sq ft, and the 24k BTU up to 1000 sq ft. Always consult the specific product's specifications for precise details.

These units utilize R-454B refrigerant, an environmentally conscious option with zero ozone depletion potential and a lower global warming potential compared to older refrigerants.

While these are air handlers, their performance in cold climates depends on the paired outdoor condenser. For extreme cold, consider MRCOOL Hyper Heat compatible condensers.

Typically, the air handler unit, a wired wall-mounted controller, and a handheld remote are included. Installation accessories like line sets are sold separately.

All Olympus 4th Gen Air Handlers require 230V, 1 Phase, 60Hz electrical service. Specific fuse breaker and minimum circuit ampacity ratings vary by model; please check individual product specifications.

MRCOOL Olympus 4th Gen Air Handlers come with a limited lifetime warranty, 7-year compressor protection, and a 5-year parts warranty when installed by a licensed HVAC professional.

Warranty registration must be completed online within 60 days of installation by a licensed professional to activate the full warranty benefits, including the limited lifetime compressor warranty.

Regular maintenance, including filter cleaning/replacement, and professional inspections, is recommended to ensure optimal performance and longevity of your system.

While these units come with their own controllers, some models may be compatible with MRCOOL Smart HVAC app for smartphone control. Compatibility with third-party smart thermostats should be verified with MRCOOL support.
