If an air conditioner is not cooling as well as it once was, it may need Freon. Some signs of this include the air conditioner being turned up to the highest setting, but barely producing any cold air, or cold air not coming out at all. Another sign is if large amounts of water are leaking from the air conditioner's air handler.Know More
An additional sign that an air conditioner may need Freon is if the unit's pipes freeze over or if the unit's outside lines frost over inside of the condenser.
Freon is used to transfer heat from inside a building. After it absorbs the heat, it transfers the hot air outside to cool the air down. The cooler air is transported back inside the building, and the process repeats itself. The Freon inside the unit continuously circles through the system, so the air conditioner does not need regular refilling. If the air conditioner is low on Freon, it is most likely caused by a leak in the unit. An air conditioner should receive an HVAC tune-up at least once a year to help prevent leaks from occurring. The best time to schedule a tune-up is in the spring before cooling companies become booked with summer orders.Learn more about Heating & Cooling
Average temperature differentials on an air conditioner thermostat, the difference between the temperatures at which the air conditioner turns off and turns on, vary by operating conditions. Temperature differentials that range between 0.8 degrees Fahrenheit and 2 degrees Fahrenheit balance the conflicting goals of comfort and efficiency.Full Answer >
To fix an air conditioner that continually freezes or ices up, check things like the air filter, refrigerant level, blower motor, evaporator coil and ductwork.

The most common reason an air conditioner is not cooling the air coming out is that it needs to be cleaned. If cleaning the system doesn't solve the problem, an air conditioner technician needs to come to check the refrigerant and electrical connections.Full Answer >
One should not attempt to troubleshoot an air conditioner if the act of troubleshooting poses a safety risk. Since an air conditioner is an electrical appliance, there are certain situations where electrical surges can pose a serious risk.Full Answer >
