Cool an air conditioning unit by building a shelter to shade it from the sun. When the sun shines on the side of the house, the entire wall heats up and transfers heat to the air conditioning unit. Therefore, planting trees or building a large shelter to shade the whole wall can be a good way to kee


There are several types of air conditioners, including self-contained window units, portable air conditioners with window exhaust kits, split central air conditioning systems and split ductless air conditioners. In addition, there are reversible air conditioners called heat pumps that can warm a hom


The four main types of air conditioning units for homes are split systems, heat pumps, central air conditioners and ductless mini-split systems. Each type has its own advantages, and the right choice for homeowners depends on the size of the home and whether the home has existing ductwork.


The Friedrich CP05G10A, LG LW6014ER and Frigidaire FFRL0633Q1 are highly rated air conditioners, according to Popular Mechanics. Other top quality models include the Frigidaire FFRE1033Q1 and the LG LW1014ER.


To determine the right size for a room air conditioner, homeowners need to calculate the square footage of the room and then use a cooling capacity chart, which is given in British thermal units (BTUs) per hour. Choosing the correct air conditioner size is important because an oversized unit wastes


Low-income households may qualify for subsidies to cover the cost of air conditioning through the LIHEAP program. These programs are administered by local governments and do not always provide funds for purchasing new air conditioners, but local charity programs sometimes make these available to vul


Window air conditioning units only come in one type, called a unitary system; however, they do come in many output sizes, ranging from 5,000 to 28,500 Btus. Unitary systems have all air conditioning parts, including compressor, condenser, coils and evaporator, in one unit.


As of 2016, air-conditioning units that are 10 inches high are not available, as standard air-conditioning units begin at 12 inches high. Friedrich's M09CHPKG Wall-mounted Ductless Split System is an exception, as it measures 10-7/8 inches high, 7-1/8 inches deep and 33-1/4 inches wide. Frigidaire's


Air conditioners work by transferring heat energy from inside the home to the exterior. Liquid refrigerant absorbs heat from the home, becomes a gas, and travels to the outside. A compressor and condenser then converts it back to a liquid, and it releases the energy, thus beginning the cycle again.


Combination heating and air conditioning units are cost-effective as concerns energy, labor and maintenance compared to split units, but they are not as effective as the alternative in maintaining appropriate energy levels in homes. Combination heating and air conditioning units tend to lose energy,
