6 Best Window Air Conditioners for Sunrooms of 2026
We compared six window air conditioners for sunrooms on capacity, room coverage, efficiency, noise and controls.
By Daniel Brooks
Updated October 21, 2026
Window air conditioners for sunrooms need more muscle than the floor area suggests, because walls of glass let in far more heat than a normal room. ENERGY STAR recommends adding 10 percent capacity for a very sunny room, and a sunroom is usually the sunniest room in the house. Our list of the best window air conditioners for sunrooms compares six units in the 14,000 to 15,000 BTU class on coverage, efficiency, noise and controls. To browse every model we cover, visit our Conventional Window Air Conditioners page.
Every pick runs on a standard 115V outlet, which matters in a sunroom addition that may not have a 230V circuit. Check that your sunroom has a double hung window, since conventional units do not fit casement or sliding windows.

What to Expect from Window Air Conditioners for Sunrooms
A sunroom heats up fast on clear afternoons and cools off at night, so the air conditioner has to handle big swings. A 14,000 BTU class unit gives you the headroom to pull the temperature down quickly, and app control lets you start it before you walk in. Inverter models such as the Midea handle the swings most efficiently.
Shades or a reflective film on the glass will cut the load on any unit. If your sunroom has only casement or sliding windows, look at a casement or portable model instead.

How to Choose a Window Air Conditioner for a Sunroom
Size the Unit to the Room
ENERGY STAR publishes this general guide for sizing a room air conditioner by floor area:
| Room Size (sq ft) | Cooling Capacity (BTU/hr) |
|---|---|
| 100 to 150 | 5,000 |
| 150 to 250 | 6,000 |
| 250 to 300 | 7,000 |
| 300 to 350 | 8,000 |
| 350 to 400 | 9,000 |
| 400 to 450 | 10,000 |
| 450 to 550 | 12,000 |
| 550 to 700 | 14,000 |
| 700 to 1,000 | 18,000 |
Reduce capacity by 10 percent for a heavily shaded room, increase it by 10 percent for a very sunny room, add 600 BTU for each regular occupant beyond two, and add 4,000 BTU if the unit cools a kitchen. Source: ENERGY STAR.
Size Up for Glass and Sun
Use the floor area as a starting point, then add capacity for the extra sun, as the ENERGY STAR note above suggests. A sunroom with west-facing glass needs the most headroom.
Check the Window Type
Conventional window units need a double hung window that slides up and down. Many sunrooms use casement or sliding windows, which need a different type of air conditioner.
Look at Efficiency, Not Just Price
Inverter compressors change speed instead of switching on and off, which saves energy and lowers noise. ENERGY STAR certification and a higher CEER also point to lower running costs over a long summer.
Decide Which Controls You Need
Mechanical dials are simple and reliable. Electronic models add a remote, a timer and sleep or eco modes, and smart units add app and voice control so you can start cooling before you get home.
How We Evaluate Window Air Conditioners for Sunrooms
We rank window air conditioners on manufacturer specifications, listing details and aggregated buyer ratings. For this list we kept only new, complete window units with a listed cooling capacity, one per brand, and excluded portable units, U-shaped and saddle models, renewed listings and listings with too little data. We weighed the feature in the title first, then cooling capacity against room size, efficiency and the size of each rating base, and finally noise, controls, installation fit and warranty.
Frequently Asked Questions
What size air conditioner do I need for a sunroom?
Start with the ENERGY STAR chart for the floor area and add about 10 percent for a very sunny room. Glass-heavy sunrooms often need the next size up.
Can I put a window air conditioner in a sunroom?
Yes, if the room has a double hung window and a nearby outlet. Casement and sliding windows need a different type of unit.
Is an inverter worth it in a sunroom?
If you use the room every day, yes. An inverter handles the big temperature swings of a sunroom more efficiently and quietly.
Can I plug a window air conditioner into an extension cord?
No. Manufacturers tell you to plug the unit directly into a properly grounded wall outlet, because an extension cord can overheat under the load.
Final Verdict
The GE 14,000 BTU Smart Window Air Conditioner is the best window air conditioner for sunrooms for most homes, with Energy Star certification, coverage up to 700 sq ft on 115V and app control. For the most efficient daily cooling, choose the Midea 14,000 BTU Smart Inverter Window Air Conditioner. For smart home routines and a 2-year warranty, the Hisense 14,000 BTU Smart Window Air Conditioner is the pick.
