Units should be selected according to room size, matching room size with the correct BTU output. Keep in mind, rooms with large windows and direct sunlight require a unit with a higher BTU capacity. See our Buying Guide for more information. 5,000 BTU = 150 sq. ft. 6,000 BTU = 250 sq. ft. 8,000 BTU = 350 sq. ft. 10,000 BTU = 450 sq. ft. 12,000 BTU = 550 sq. ft. 15,000 BTU = 700 sq. ft. 18,000 BTU = 1,000 sq. ft. 24,000 BTU = 1,500 sq. ft.
For Denali Aire Window ACs, the 5,000-15,000 BTU models use a 15A-115V outlet. 18,000 BTU models use a 15Amp-230V outlet. 24,000 BTU models use a 20A-230V outlet.
Do NOT use an extension cord, outlet adapter, or remove the grounding prong. This is not only for your safety as these things can cause fire hazards, but also to maximize the performance and longevity of your unit.
For optimal performance, the operating temperatures for these units are: Outdoor 61 ~ 110F, 80% Relative Humidity (RH); Indoor 61 ~ 90F, 80% Relative Humidity (RH). Working outside of these temperatures can decrease the overall performance of the unit.
While both R32 and R410A are considered environmentally safe there are a few differences to note. R410A has an ODP (Ozone Depletion Rate) of 0 and a GWP (Global Warming Potential) of 2,090. R32 refrigerant has an ODP of 0 and a GWP of 675. R32 is the most efficient and environmentally friendly refrigerant available.
Do NOT remove the white foam that is visible through the louvers inside of the unit. This foam helps insulate the unit, blocks sound from the compressor and guides the airflow. For models 1DAC24K/1DACH24K you must remove shipping blocks and packing foam attached with zip ties located on the inside of the unit between the compressor and fan motor.
This is normal, especially on days of heavy rain or high relative humidity. If you think your unit is collecting too much water, ensure that your unit is installed with a slight downward slope toward the outside, allowing the accumulated water to drain out. Do NOT drill additional holes anywhere on the unit, as these units are manufactured with a drain hole for excess water. Doing so will void the warranty.
After the fan motor runs for a total of 250/500 hours (see chart below), the Filter light will turn on as a reminder to clean the filter(s). Once they’ve been cleaned, simply press the Filter button to reset the reminder. To clean the filter, use liquid dish soap or mild detergent and warm water. Dry filter completely before placing it back into unit. Alternatively, you may vacuum the filter to remove dust particles.

Check filter at least once a month according to instructions in the User Manual. Clean the cabinet and front panel of the unit with a damp cloth in a solution of warm water and mild liquid soap, then wipe dry. Check out this video that will show you how to disassemble and clean a Perfect Aire window air conditioner. Note: Avoid soaking the control panel of the unit with too much liquid; this may cause damage to the unit.
To store the air conditioner for an extended time period, remove the unit from the window according to the instructions. Remove batteries from the remote, keep the unit upright, cover in plastic, or place in the original box; store in a cool, dry place.
This is necessary so the oils in the compressor settle; not doing so can affect the performance of the unit.
Models 1DAC8K, 1DAC12K, 1DAC6K, 1DAC10K, 1DAC15K, 1DAC18K, 1DAC24K, 1DACH18K, 1DACH24K, and 1DACS10K includes either "I FEEL" or "FOLLOW ME" feature on the remote. This enables the remote to function as a portable thermostat when placed on the other side of the air conditioner out of direct air flow. When activated, the remote takes the temperature at its current location, sending a signal to the air conditioner to optimize the temperature around you. During this operation, make sure there is nothing blocking the path between the remote's and the units sensors; max distance for this function is 16 feet.
The following Denali Aire window air conditioners are Energy Star: 1DAC6K, 1DAC8K, 1DAC10K, 1DAC12K, 1DAC15K, 1DAC18K, 1DAC24K.
Only models 1DACH18K, 2DACH18K, 1DACH24K, and 2DACH24K have Heat mode; where the H identifies Heat. These units are primarily used for cooling but do have electric heat. When this mode is active, the unit pulls in outside air, passing it over electric strips to produce warm air. This function is meant only to supplement, not to be used as a main heating source. Note: heating output will be less than the unit’s cooling capacity.
For casement window openings, we recommend 1DACS10K. This unit is intended to be installed with a maximum 16 ¼” W x 39 ½” H, minimum 15 ½” x 21 ⅓” window. In cases where the supplied panel is too big you can cut the panel to size. This unit will not work with crank operation windows, unless the hinge, sliding arm, and windowpane are first removed. We recommend hiring an experienced technician to assist with the install.
Registration can be completed here. Registration is used by Denali Aire to protect customers by recording purchases. In case of a recall or other very important information pertaining to the machine, Denali Aire can quickly and efficiently contact you. Registration does not confirm the warranty status – a valid receipt is still required to confirm warranty. We highly suggest registering the unit as soon as possible to stay updated, but it can technically be done at any time.
