When the weather begins to warm up, which is close to year round here in South Florida, it is time for homeowners to begin preparation for their air conditioning units to get them ready for anticipated heat waves that can be uncomfortable. Unfortunately, a majority of people will find that their air conditioning units fail to function properly when they least expect it. Here is how you can try and diagnose the problem yourself.
The following is a basic troubleshooting guide for air conditioning:
1. Before you even begin troubleshooting, ensure that the thermostat’s selector switch is on a cool setting and lower in comparison to the current room temperature. It is a step to check if there really is a problem. It is important to note that it is also the first thing that an air conditioning repair company will check. In case of a thermostat which is programmable, ensure you change its batteries so that they are fresh and new.
2. Check if the unit is receiving power. Do this by moving its fan switch from an auto setting to an on setting. There is power if the blower runs but if nothing happens, it is either that the power is not connected or the control is burned out.
3. For systems that utilize a furnace for heat, the status of the emergency switch should be checked whether it is on or off.
4. Check for tripped breakers or blown fuses in the circuit breaker panel. Air conditioning systems that are blowing fuses pose a more serious problem that can damage the entire system.
5. Move the air conditioning unit’s thermostat setting below the room temperature. This should be done with the fan switch on an auto setting and selector switch on a cool setting. Check if the unit’s blower is running but its condenser fails to engage or if the outdoor unit fails to come in, the circuit breaker or fuse should be checked. In case the circuit breaker is engaged like it should be then proceed to check the condenser. There are condensers that are equipped with high a cut out (high pressure), it should be reset.
6. Check if both units are operational but the air conditioning still fails to cool. If so, check the bigger copper lines that exit the condenser but do so carefully. Warmth indicate that the system has exhausted freon or that the compressor is not running. Frozen lines indicate an air flow problem. This may be because the filter is clogged or the closure of too many registers. Perhaps they may even be something covering or blocking the return air duct. Check if any of the room air ducts are closed and open them. Furthermore, ensure the return air duct is wide open so as to access air.
7. Shut the system down if it is frozen and allow it to completely thaw out because low Freon can lead to a freeze-up.
