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 in Heating & Cooling
An air conditioner coil is the part that turns a liquid chemical such as Freon into a gas and absorbs heat while creating cool air. The coil functions as a heat exchanger, because it draws out heat and creates the cool air that blows out of the air conditioner.Full Answer >
During the warmer months, the thermostat to an air conditioner should be set at 78 degrees Fahrenheit. If this is not comfortable, some experts recommend lowering the temperature to no less than 74 degrees to avoid high utility costs.Full Answer >
An air conditioner thermostat is a device which displays room temperature while working in tandem with the air conditioner. Thermostats can be used to automatically adjust the temperature in a room or to gauge temperature for manual adjustment.Full Answer >
To troubleshoot an air conditioner thermostat, identify the type of thermostat that is in use, check that the unit is receiving power and ensure the unit is installed properly. Most thermostats are either electromechanical or electronic, which affect how the room's temperature is determined.Full Answer >
