Will it cool your room?

Room size (assumed)400 sq ft ≈ 37.2 m²

Fits a 37.2 m² roomapprox

This unit's cooling matches a 400 sq ft room, on an estimate from its cooling power. Set your room size to check the fit for your space.

Running cost

Mini-splits are rated on SEER2, a seasonal scale, not the ENERGY STAR annual-kWh figure this dollar estimate is built from, so there is no comparable figure to show here. A blank is missing data, not a worse result: a mini-split is often the more efficient choice.

Installation cost

$2,500-6,000 fully installed for a typical room (the equipment is roughly $700-1,800, professional installation roughly $1,500-4,000+ depending on line-set run, electrical and access). The unit price you see here is hardware only; installation is the larger, separate cost.

A typical range for this system type, for comparison only, not a quote for this unit. The actual price depends on the line-set run, electrical work and access.

Installation & the rules that apply

This is a single split. This is where regulation bites. Under EPA Section 608 the refrigerant circuit may only be opened by a certified technician, and the EPA is explicit that this includes connecting or disconnecting the pre-charged line sets sold with "DIY" mini-split kits. No federal law stops you doing the mounting, bracketing and line routing yourself, but handling the refrigerant without certification voids the warranty and is a violation. Most US jurisdictions also require permits for a new outdoor unit: typically mechanical or building for the wall penetration and mount, plus electrical for the dedicated 240 V circuit and disconnect. An HOA nearly always has to approve exterior equipment in advance, and local noise ordinances can cap how loud the condenser may be at the property line. This varies by city and county, so confirm with your building department before buying hardware.
