DIY, Hyper Heat, Advantage, and Olympus ENERGY STAR are not interchangeable. Warranty, heat, and who hangs it all change.

Which MRCOOL do I need?

Montana pick

DIY Hyper Heat

Rated −22°F to 122°F. ENERGY STAR® Cold Climate. For a Flathead house, cabin, or shop that has to heat — this is where we start, not the cheaper 115V 12k. 12k and 18k only.

Hyper Heat brochure (PDF)

Standard DIY 5th Gen

Complete single-zone kits. They heat and cool; they are not Hyper Heat. 9k and 12k run on 115V. 9k–24k are ENERGY STAR® and tax-credit eligible; the 36k is not.

5th Gen DIY brochure (PDF)

DIY 5th Gen multi-zone

One outdoor unit, 2–6 wall heads. Indoor sizes on the factory chart are 6k–24k (not 36k). Click a condenser and pick a size for each zone — we’ll only allow a published mix. Coverage ~750 sq ft (18k) up to ~2,290 sq ft (55k). 230V. Not Hyper Heat.

DIY indoor heads

Extra 230V wall air handlers for the multi-zone condensers above. Published multi-zone indoor sizes are 6k, 9k, 12k, 18k, and 24k. The 36k head is a replacement indoor for the 36k complete kit — it is not on the factory multi-zone chart. Each head still needs its own line set.

DIY indoor head · 230V

DIY 36k indoor head — 230V

Up to ~1,550 sq ft

Largest DIY 5th Gen wall air handler. Replacement indoor for the 36k single-zone kit. Not on the factory multi-zone matchup chart — multi-zone indoor max is 24k.

Finish the install

What’s in the kit

Olympus ENERGY STAR — contractor install

Not DIY, and not Hyper Heat. Factory heat to about −13°F. High SEER2, copper line set, we flare and vacuum. For a Flathead house that has to heat in January, start with DIY Hyper Heat — we can hang that kit.

Olympus wall heads

Advantage 5th Gen — contractor install

Contractor-grade. No Quick Connect line set in the box. Priced at MSRP (the portal does not list MAP on Advantage). A professional HVAC contractor has to flare, vacuum, and start it.

Advantage 5th Gen brochure (PDF)

Advantage condensers and heads

Olympus multi-zone condensers

3 to 6 zone outdoor units. Mix wall heads, ceiling cassettes, and ducted air handlers on the condenser page. Must be installed by a professional HVAC contractor — not a DIY multi-zone.

Olympus multi-zone brochure (PDF)

Ceiling cassettes

Olympus cassettes with the grille/panel. Flush in a ceiling. Pair with an Olympus condenser.

Ducted air handlers

Slim Olympus ducted units for a chase or closet. Ductwork is on the job, not in the box.

Extra DIY line sets

Complete kits already include 25 ft. Order a longer Quick Connect set or a coupler if the run is more than that. R-454B, MAP.

Line-set couplers

Join two pre-charged line sets when one run isn’t long enough.

Olympus copper line sets

Standard insulated copper with wire. Vacuum and flare required — a professional HVAC contractor installs these with Olympus equipment. Not a DIY Quick Connect set.
