Room & Space Coverage — 18,000 BTU

The 18K BTU Wall Mount Air handler 230 volt 19 SEER with Enhanced WiFi (Works with Alexa, Works with Google Assistant) 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.

Power & Electrical Requirements

Power requirement: 208-230V (standard US residential 240V service).

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.

Frequently Asked Questions

Everything you need to know about this product

What size room will the 18K BTU Wall Mount Air handler 230 volt 19 SEER with Enhanced WiFi (Works with Alexa, Works with Google Assistant) 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 the refrigerant, 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?

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.
