Efficiency is the CEER each listing publishes (higher uses less electricity). The voltage is the one the retailer or the listing states; check it against your outlet before you buy a large unit. Through-the-wall units and PTACs have their own chart, matched to the wall sleeve they fit.

Figures are the ones each listing publishes; "Not published" means the listing does not state that figure. Where one model number is sold as more than one listing, the row shows the cheapest and links the others. Prices are live retailer offers, checked October 6, 2026, and change often; compare.ac may earn a commission on purchases, at no cost to you.

Window air conditioners: questions, answered

What is the cheapest window air conditioner in stock right now?

The GE AWAS05BWF (5,000 BTU) at $159 from Abt Electronics, the lowest live price among the 111 in-stock window air conditioners in this chart. The cheapest unit is only a good buy if it is the right size for your room, so check the size column first.

What is the quietest window air conditioner in stock?

Of the 65 in-stock window air conditioners whose listing publishes an indoor noise rating, the lowest is 38 dB(A), on the Soleus Air WS5-10HW-301 (10,000 BTU) and the Soleus Air WS5-12HW-301 (12,000 BTU). The GE Profile PHNT10CC (10,300 BTU) is close behind at 40 dB(A), a gap small enough that you may not hear it. Listings do not all say how they measured, so treat a gap of a few decibels as close. Sort the chart by noise to see every rating.

Which window air conditioner is the most energy efficient?

Among the 34 in-stock window air conditioners rated on the CEER scale, the GE Profile PWJV08WWF (8,000 BTU), the GE Profile PWJV10WWF (10,000 BTU) and the GE Profile PWJV14WWF (14,000 BTU) share the highest at CEER 16. A higher CEER means less electricity for the same cooling. A listing that publishes no CEER figure shows as not published and is not ranked.

Do window air conditioners need a special outlet?

Of the window units in this chart whose listing or retailer states a voltage, 72 run on a standard 115-volt outlet (up to 15,000 BTU) and 30 need a 208/230-volt circuit (from 12,000 BTU). Check the plug and the circuit before you buy a large unit; the chart shows each unit's voltage where it is stated.

Do window air conditioners heat too?

31 of the 151 window air conditioners in this chart also heat; the rest are cooling only. The chart marks which is which.

What size window air conditioner do I need?

Size it to the room rather than buying the biggest you can afford: an oversized unit cools in short bursts and leaves the air damp. The sizing calculator turns your room's square feet, sun and occupancy into the BTU to look for, using ENERGY STAR's sizing chart, and lists the in-stock units that fit.
