As with any appliance, overtime, it will start to have problems as it gets older. Some of the problems that can occur with a central air conditioner you can troubleshoot yourself while others will need to be diagnosed by a HVAC air conditioning repair service. Your central air conditioner comprises of the evaporator and condenser and is connected to the home’s forced air distribution system.
Some of the problems that you can have with your central air conditioner can include:
• It does not turn on and stops working sometimes-if it stops functioning you should check the circuit breakers and fuses. You should also make sure that the thermostat is below the current temperature and is adjusted to cool. You also need to make sure that the condenser power and furnace power switches are in the “on” position.
• The compressor switches off-this can mean that the high-pressure switch was tripped so you can reset it by looking at the access panel of the compressor and press the button to reset it.
• It is making a strange noise-if your central air conditioner is making a lot of noise you should check to see if the fan blades are clean. Make sure that the unit is turned off before attempting to check the blades.
• The evaporator coils has built up frost on it-if the temperature is below sixty degrees with the unit on, frost could build up on the unit’s evaporator coils. When you see this happen you should switch off the ac unit immediately.
• Leakage of refrigerant-this can happen if your central air conditioner is not installed properly or low on refrigerant. You should call your local ac repair service to have a trained technician fix the problem.
• Leaking air conditioner-if you notice water is leaking inside your system it normally means it is not cooling. This could be the result of a frozen cooling coil. It can be caused by airflow that is insufficient or a low refrigerant charge. Again, you should call your local ac repair service because a trained technician needs to fix this problem.
• Thermostat temperature and room temperature do not match-if the temperature that is set on the thermostat is higher than the temperature in the room your thermostat may not be properly calibrated. It could also be that the thermostat has been installed in an area where it cannot sense the air in the room correctly.
• It is on but the air is not becoming cooler-your central air conditioner could be dirty and needs to be cleaned.
