Quick Buying Guide

Choose by Room Size

Use manufacturer room-coverage guidance as a starting point. Ceiling height, insulation and direct sun can increase cooling demand.

Verify Electrical Service

Confirm 115V versus 230V, plug type, amperage and circuit requirements for the exact model.

Compare BTU Ratings Correctly

Portable units may show DOE/SACC and ASHRAE ratings. Compare models using the same standard.

Frequently Asked Questions

What size air conditioner do I need?

Use manufacturer coverage guidance and account for ceiling height, insulation, sun exposure and internal heat loads.

What is DOE/SACC versus ASHRAE BTU?

They are different portable-air-conditioner rating standards. Compare models using the same standard.

Is a window AC more efficient than a portable AC?

Efficiency varies by exact model and rating method; compare verified efficiency and capacity data for the same application.

Do portable air conditioners need a window?

Portable units require a route for the exhaust hose, commonly through a compatible window kit.

Do portable AC units need to be drained?

Drainage requirements are model and operating-condition dependent. Review the exact model instructions.

What is the difference between 115V and 230V?

They require different electrical service, receptacles and circuits. Match the exact model requirements.

Can a window AC provide heat?

Some models include supplemental electric resistance heat; this does not make them heat pumps.
