What Are The Different Types Of 12000 BTU Air Conditioners?

There are several AC styles within 12,000 BTU rating range. Each kind has its own traits, making every one an individual choice for the purchaser. Which one is the finest for you?


For a mini-split AC, you have condenser unit outside (or ‘split’). Within each room that contains climate control is a mini air handler (signifying the ‘mini’).

Every air handler is controlled independently, letting you set diverse temperatures in different rooms. They are taxing to install but present more localized management. The mini-split structure can end up costing more on energy bill. The trade-off is your house won’t have cold/hot spots.


Window AC units comprise all-in-one forms that assemble in your window. Condenser unit sits at back where the fan shoves air over evaporator coils. The condensation exhausts through a little drain pan outside as cold air blows within.

Large windows with minute window ACs require extending flaps to avert outside air, pests, bugs, and other unnecessary things from getting inside (or outside) of space on both sides of AC. If you obtain a window unit that is too outsized for window space, you wouldn’t be able to utilize the unit. Precision measurements are vital in window AC selection.

There are some unique considerations. You must determine what manner of window it’d be installed in, standard, Top 15 Best 12000 BTU Air Conditioners - Complete Guide & Reviews for 2020sliding, or else casement, and locate a compatible unit.

This is a grand option if you desire an everlasting fixture in a room without windows or if you simply desire to keep the windows unfettered! However, they’re difficult to install, naturally needing professional help to guarantee you won’t unintentionally hit pipes and wires.

One of the major considerations is to utilize a customary “sleeve” to lodge the unit or if you desire to find a model with slide-out chassis. AC with slide-out chassis are sold as single-piece and can habitually be utilized as window units, so you get additional versatility.


Portable ACs are little, weighty items that sit on floor in the area you desire to cool. It contains a drip-tray for condensation (some need emptying physically, others disperse by themselves). There is an exhaust vent resembling a dryer vent hose. This requires to be mounted in a window to allow hot air out of room. Portable units can contain elevated BTUs but aren’t planned to cool huge, airy spaces. A bedroom/living room cools with maximum efficiency.

Energy Star-Certified

If you’re anxious about electricity used by AC, look for an Energy Star-certified model. These units need to satisfy definite efficiency requirements sanctioned by U.S. Department of Energy, and normally, they’re 10% extra-Top 15 Best 12000 BTU Air Conditioners - Complete Guide & Reviews for 2020proficient than mandated by government standards. While several might have an advanced upfront price tag, you’ll salt away funds on energy in the long-term.
