Air conditioning (often referred to as AC, A/C, or air con)[1] is the process of removing heat and moisture from the interior of an occupied space, to improve the comfort of occupants. Air conditioning can be used in both domestic and commercial environments. This process is most commonly used to achieve a more comfortable interior environment, typically for humans and animals; however, air conditioning is also used to cool/dehumidify rooms filled with heat-producing electronic devices, such as computer servers, power amplifiers, and even to display and store some delicate products, such as artwork.

If you believe that the ac not working or you’re getting little or no cold air, check these three things first. Make sure all the registers in the house are wide open. Then be sure the furnace filter is clean. Then go outside and clean off the condenser coils (Photo 2). If several registers were closed or the filter was clogged, the reduced airflow could have caused the evaporator coil to ice up and stop cooling your home. If you’ve changed the filter and opened all the registers and you’re still not getting airflow at the registers, deice the A-coil. Move the thermostat mode switch from “Cooling” to “Off” and move the fan switch from “Auto” to “On.” Let the blower run for at least 30 minutes or until there’s good airflow at the registers. Then turn the AC back on to test it. If it works for the next 12 hours, you’ve solved the problem.
For residential homes, some countries set minimum requirements for energy efficiency. In the United States, the efficiency of air conditioners is often (but not always) rated by the seasonal energy efficiency ratio (SEER). The higher the SEER rating, the more energy efficient is the air conditioner. The SEER rating is the BTU of cooling output during its normal annual usage divided by the total electric energy input in watt hours (W·h) during the same period.[33]

This doesn't mean air conditioning isn't right for your home. Some people are more sensitive to heat than others. Even if you can't justify the expense of central air conditioning, window air conditioning units will allow you to cool individual rooms tailored for your needs. If you work from home, you may want to put one of these units in your home office. If you have trouble sleeping with even modestly warm temperatures, you may want to put one in your bedroom. If you love to cook and spend long afternoons using the oven, your kitchen may be the place.
“Air conditioners contain refrigerant, which allows the system to run efficiently, releasing heat from the air to cool it. Air conditioners are charged with refrigerant upon installation; a poor charge or a refrigerant leak can cause the system’s refrigerant level to fall below the proper amount. To remedy this, the home AC repair which is performed is a refrigerant recharge, accompanied by fixing the leak if that was the source causing low refrigerant levels.
The myth that most people believe is that if you add more refrigerant to the unit it will cool better. This is only true if the evaporator coil is operating below freezing. The unit must have a balanced charge at the correct refrigerant pressure for the temperature and usually, only an HVAC professional can charge your unit properly. Another misconception about refrigerant is that the unit burns it up and it must be replaced from time to time. This is not true. Furthermore, the refrigerant loop is a closed system and barring any leaks the air conditioning system should never need any refrigerant.
Check that the 240-volt circuit breaker (double-pole breaker) controlling the air-conditioning compressor/condensing unit and the 120-volt circuit breaker controlling the furnace blower or separate air handler, is in the "On" positions. If a circuit breaker has tripped or a fuse is blown, then reset the circuit breaker or replace the fuse. If you reset the breaker or replace the fuse and they trip or blow again, stop and call an air-conditioning service technician, as you may have a more serious problem.

Because an air conditioner moves heat between the indoor coil and the outdoor coil, both must be kept clean. This means that, in addition to replacing the air filter at the evaporator coil, it is also necessary to regularly clean the condenser coil. Failure to keep the condenser clean will eventually result in harm to the compressor, because the condenser coil is responsible for discharging both the indoor heat (as picked up by the evaporator) and the heat generated by the electric motor driving the compressor.

In 1995, Germany made CFC refrigerators illegal.[22] DuPont and other companies blocked the refrigerant in the U.S. with the U.S. EPA, disparaging the approach as "that German technology".[21][23] Nevertheless, in 2004, Greenpeace worked with multinational corporations like Coca-Cola and Unilever, and later Pepsico and others, to create a corporate coalition called Refrigerants Naturally!.[22][24] Then, four years later, Ben & Jerry's of Unilever and General Electric began to take steps to support production and use in the U.S.[25] In 2011 the EPA decided in favor of the ozone- and climate-safe refrigerant for U.S. manufacture.[17][26][27]
Believe it or not, the evaporator coils inside the AHU (Air Handling Unit) are freezing. You may notice the refrigerant lines on the condenser or at the AHU are frozen with ice build-up. The frost or ice builds up on the evaporator coils and blocks air flow (low air flow and no cooling are a sign of a low charge). A low refrigerant charge will cause the evaporator coil to operate at or below freezing. Since the coil typically operates below the dew point, it draws condensation out of the air. When the evaporator coil begins operating below freezing all this condensation freezes to the evaporator coil and the unit stops cooling.
7) Schedule an annual tune-up with an HVAC professional. A trained HVAC technician can detect most problems before they become major ones. With a cost of around $100 for a routine maintenance call, the benefits will likely outweigh the costs by a considerable margin. A typical tune-up will include various tests to ensure your unit’s internal parts are functioning correctly, as well as a filter check, and a refrigerant charge if needed. Your technician will likely also clear the drain, and clean your unit thoroughly inside and out.

Reinstall the access panel and disconnect block. Turn on the circuit breaker and furnace switch. Then set the thermostat to a lower temperature and wait for the AC to start (see “Be Patient at Startup,” below). The compressor should run and the condenser fan should spin. If the compressor starts but the fan doesn’t, the fan motor is most likely shot. Shut off the power and remove the screws around the condenser cover. Lift the cover and remove the fan blade and motor (photo 7). Reinstall the blade and secure the cover. Then repower the unit and see if the fan starts. If it doesn’t, you’ve given it your best shot—it’s time to call a pro.
