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

Room & Space Coverage — 12,000 BTU

The Advantage 5th Gen 12k BTU 115V System delivers 12,000 BTU of cooling and heating capacity, sized for spaces up to 600 sq ft in standard 8-ft ceiling rooms with average insulation. At this capacity the unit is ideal for bedrooms, home offices, sunrooms, and single-room additions up to the stated square footage. Rooms with one exterior wall and average shading sit comfortably in the middle of the coverage range.

Power & Electrical Requirements

Power requirement: 115V (standard US 120V household outlet).

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-454B refrigerant. R-454B is the EPA 2025-compliant low-GWP replacement for R-410A, required for new-manufacture equipment — lower global-warming footprint without an efficiency penalty.

Frequently Asked Questions

Everything you need to know about this product

What size room will the Advantage 5th Gen 12k BTU 115V System cool?

At 12,000 BTU this unit is sized for rooms up to 600 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-454B, plus standard HVAC tools (vacuum pump, manifold gauges, nitrogen kit). Expect a one-day install on a single-zone system, more on multi-zone.

What electrical circuit do I need for installation?

115V 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.

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?

What size room does 12,000 BTU cover?

A 12,000 BTU unit is sized for rooms up to 600 sq ft. Proper sizing depends on ceiling height, insulation, climate zone, and window exposure. Use our system finder for a precise recommendation.
