One ton of cooling equals 12,000 cooling BTUs per hour. BTU is short for the British Thermal Unit, which is a measure of heat in units of energy. It is the amount of heat required to raise the temperature of one pound of water one degree Fahrenheit. 12,000 BTUs per hour is the rate of heat transfer it takes to melt one ton of ice at 32 degrees Fahrenheit in 24 hours. Thus, a three ton unit would be (3 x 12,000 BTU/hr) or 36,000 BTUs. An air conditioner takes the heat that is inside the home and moves it outside the home through the medium of refrigerant.

Whole-house air cleaners are designed to fit perfectly within your central furnace and air conditioning system. Unlike many air cleaners that are situated in a single room of the house, a whole house air cleaner is installed directly into your ductwork and works in conjunction with your heating and cooling system. It operates out of sight of most living spaces and provides up to 99.98% cleaner air throughout your entire home. Air purifiers can also be installed that way and can provide even more protection.

Covering the outdoor unit is not always necessary. The units are made to withstand the weather. If you have a unit under or near a tree, it is a good idea to cover the unit to keep debris from building up inside the unit during the off season. Never cover the unit completely. The cover should allow the unit some air flow at the bottom so as not to trap moisture inside. Some customers will put a piece of plywood on top of the unit. This will help to protect the unit against damage from falling ice and help keep rodents from entering your unit. Make sure any cover is removed before the start of operations the following spring.
