Choosing the right air conditioner unit, when central HVAC may not an option, involves several factors. To determine what type of air conditioner to buy, consider the following questions: You may also need to factor in the ease of installation and the energy efficiency the AC unit offers. Types of air conditioners vary depending upon the window space available. hung sash window that opens up and down typically can accommodate a standard window air conditioner, while a slider/casement style AC unit is needed for casement windows that crank open or slide open horizontally. These types of indoor air conditioners sit on the window sill with the window partially open, held secure in place by the window sash and/or other manufacturer recommended methods. The chassis is the supportive frame for a window air conditioner unit. Units built with a slide-out chassis can be removed and may be installed through a wall inside an air conditioner sleeve (which may require brackets for support.)

Certain in-wall AC units can be installed so they sit flush with the wall, creating a sleek, minimalistic look. In-wall and slide-out chassis air conditioner units don’t have the same side-vents a regular window air conditioner has, but they do offer a high cooling capacity ideal for bedrooms and offices. Note: The thickness of your wall will determine if installing an in-wall air conditioner is possible. BTUs, or British thermal units, are units of energy. Cooling is measured in BTU per hour. According to Energy.gov, “Based on size alone, an air conditioner generally needs 20 BTU for each square foot of living space.” On average, most window AC units or portable air conditioners range from 5,500 BTU per hour to 14,000 BTU per hour. You may also see units with a cooling capacity size of a ton. A ton, in air conditioner cooling terms, means that unit has a rate of 12,000 BTU per hour. While the size of the room is key in figuring how much BTU is needed, don’t forget to consider how much sun or shade the room receives, the effectiveness of the room’s insulation and the height of the ceilings — it takes more energy to cool a room with 9-foot or higher ceilings.

Tip: When buying a window air conditioner, avoid one that is oversized (too high BTU) for the space. Use a BTU calculator to figure the right size for the space. A portable AC unit is an ideal choice if your room has only one window or a window AC unit isn’t permitted by your landlord. Consider a portable air conditioner for rooms that need supplemental cooling, such as offices, enclosed porches or loft rooms. what's the best ac unit for a homeYou can find units with timers, multi-fan settings and that are easy to move from room to room as needed.how to fix a noisy ac unit Trust P.C.

HVAC (Heating and Cooling Systems): Right-size Heating and Cooling EquipmentThere are 12,000 Btu’s per ton. The number 24 in the model number indicates the unit is 24,000 Btu’s, divided by 12,000 Btu’s per ton, equals 2 tons. 24,000 Btu’s/12,000 Btu’s per ton = 2 tons If you’re still unsure which system size is right for you, or if you’re having difficulty downloading the Air Conditioner Size Calculator , please e-mail us or call us toll free number at 1-855-634-5588. (Hint: Use the larger of the two numbers above if you’re unsure of your home’s insulation) Simply multiply the appropriate factor above by your home’s total heated square footage to arrive at your approximate required heating capacity. For example, if a furnace has a listed input rating of 100,000 Btu’s and an efficiency rating of 80%, it will produce For this example, using an 80% efficient furnace, the 2000 square foot home above would require a 100,000 Btu input furnace which will produce the necessary 80,000 Btu’s output of heat.
