What this specific model is sized for, how it installs, how it performs, and what it costs to run.

Room & Space Coverage — 18,000 BTU

The Olympus 18,000 BTU Ductless Mini-Split Condenser - 230V/60Hz delivers 18,000 BTU of cooling and heating capacity, sized for spaces up to 900 sq ft in standard 8-ft ceiling rooms with average insulation. At this capacity the unit handles medium primary rooms, master suites with attached bath, converted garages, and workshops. If your space includes a sunny west-facing wall or a finished bonus room above it, lean toward the upper end of the coverage range. As a multi-zone system this condenser supports up to 2 independent indoor heads, each with its own thermostat and mode — so bedrooms can cool while the living room heats, on one outdoor unit.

Efficiency & Operating Cost

This unit is rated at 22.9 SEER2 and 13.9 EER2 at full load. SEER2 measures seasonal cooling efficiency — higher is better — and 22.9 puts this in the premium efficiency tier. For heating performance it carries a 10.5 HSPF2 rating, which translates to roughly 300–350% heating efficiency versus resistance electric — one kilowatt-hour of electricity moves three kWh of heat into the space at mild outdoor temperatures. Running the unit 8 hours a day at full load draws roughly 189 kWh/month — about $30/month at the US average $0.16/kWh residential rate. Real-world draw is usually 30–50% lower because inverter compressors modulate down most of the time. ENERGY STAR certification makes this SKU eligible for federal tax credits (25C in 2026, up to 30% / $2,000 for qualifying heat pumps) and most state/utility rebate programs — check your state page for specific amounts.

Power & Electrical Requirements

Power requirement: 208-230V 1-phase 60Hz (standard US residential 240V service). Minimum circuit ampacity is 18A with a maximum overcurrent protection of 25A. Wire the outdoor unit with 10 AWG copper on a dedicated 25A double-pole breaker (or single-pole at 120V), with a disconnect within sight of the condenser per NEC 440.14.

Install Difficulty — Professional Install

This is a professionally-installed condenser that requires a licensed HVAC technician with EPA 608 certification. The tech will pull a vacuum on the line set to 500 microns, pressure-test with nitrogen, release the factory charge, and commission per MrCool's startup procedure. Budget 1 full day for install on a single-zone system. Ships with R-410A refrigerant. R-410A is a mature, widely-serviced refrigerant; service technicians and parts are available at any HVAC supply house.

Sound Level & Comfort Features

Rated sound output is 58.5 dB(A) at full operation.

Warranty & Certifications

When you register your unit within 60 days of purchase you get 5-year on parts and 7-year on the compressor through MrCool's registered warranty program. AHRI certified — required for most utility rebate and tax credit programs.

What's in the Box & Compatibility

Ships as a Mini-Split.

Frequently Asked Questions

Everything you need to know about this product

What size room will the Olympus 18,000 BTU Ductless Mini-Split Condenser - 230V/60Hz cool?

At 18,000 BTU this unit is sized for rooms up to 900 sq ft under standard 8-ft ceilings with average insulation. Add 10–20% for sun-exposed rooms, poorly insulated spaces, or ceilings above 9 ft.

Do I need a licensed HVAC installer?

Yes — this unit is professionally-installed. The installer needs EPA 608 certification to handle R-410A, plus standard HVAC tools (vacuum pump, manifold gauges, nitrogen kit). Expect a one-day install on a single-zone system, more on multi-zone.

Is this unit eligible for the federal 25C tax credit?

At 22.9 SEER2 this unit meets the efficiency thresholds most ENERGY STAR cold-climate heat pump programs require, which is the trigger for the 25C credit (up to 30% / $2,000 in 2026). Confirm with your tax advisor and save the AHRI certificate from your order confirmation.

What electrical circuit do I need for installation?

208-230V dedicated circuit with the disconnect within sight of the outdoor unit per NEC 440.14. An electrician will size the breaker based on the minimum circuit ampacity shown on the nameplate. Budget $400–$900 for a new dedicated 240V circuit if one isn't already present.

Can I add more indoor units later on this condenser?

Yes — this multi-zone condenser supports up to 2 indoor heads. As long as the total BTU of all heads doesn't exceed the condenser's rated capacity, you can phase in additional zones over time using unused refrigerant ports.

What warranty do I get?

5-year parts warranty with registration (3-minute process at mrcool.com within 60 days of purchase). Without registration, coverage drops significantly — make registration part of your install-day checklist.

How fast does HVACZAR ship this unit?

Shipping is calculated at checkout from the order weight, and you see the exact charge before paying. In-stock SKUs leave the warehouse within 1–3 business days. Transit time is 3–7 business days via truck freight (with liftgate delivery) for outdoor units and UPS Ground for accessories. Tracking is emailed at pickup.

What if it arrives damaged or I change my mind?

Inspect the unit before signing for freight delivery. If there is visible damage, note it on the delivery receipt and refuse the shipment — we ship a replacement at no cost. Unopened and unused units can be returned within 30 days for a refund less outbound shipping.

What is the warranty on the Olympus 18,000 BTU Ductless Mini-Split Condenser - 230V/60Hz?

The Olympus 18,000 BTU Ductless Mini-Split Condenser - 230V/60Hz comes with a 5-year Parts/7-year Compressor/1-year Remote manufacturer warranty when purchased from HVACZAR, an authorized MrCool dealer. Register your unit after purchase to activate full warranty coverage.

How long does shipping take?

Shipping is calculated at checkout from the order weight. Most MrCool systems ship within 1-3 business days and arrive in 3-7 business days via FedEx, UPS, or truck freight with liftgate delivery.

What size room does 18,000 BTU cover?

A 18,000 BTU unit is sized for rooms up to 900 sq ft. Proper sizing depends on ceiling height, insulation, climate zone, and window exposure. Use our system finder for a precise recommendation.

What is the efficiency rating?

This system is rated at 22.9 SEER2, meeting or exceeding Energy Star efficiency standards. Higher SEER2 ratings mean lower electric bills and better cooling efficiency.

Do you offer returns?

Yes. HVACZAR offers a 30-day return policy on unopened, unused products in original packaging. Contact us to initiate a return and receive a return authorization number.
