Air conditioner repair is inevitable. Even the most reliable model will fail sooner or later. There are several simple tips to extend the life of the conditioning appliance and avoid many breakdowns. Before we begin to review the faults, you must understand that an air conditioner is a very complex piece of equipment that requires regular maintenance and careful handling. Before you start puzzling over the cause of the breakdown, you need to start with the simplest. Check for the plug defectivity. Plug in another electrical appliance, carefully inspect the plug and cord of the furnace. When the air conditioner is connected to a separate line on the automatic board, turn the toggle switch on and off. If it still doesn't work, measure the voltage. When the air conditioner refuses to heat, it is necessary to check the next parts. If the circuit breaker keeps getting tripped when the air conditioner tries to run, there might be a problem with the wiring inside the unit. If the breaker trips, do not keep switching it back on because this can cause more damage to the unit. Another cause of a tripped breaker, could be a dirty air filter or blocked airways. Professional HVAC technicians can check this and clean your filter quickly. Your thermostat could also be a source of bad wiring. Thermostats that have not been properly maintained or if it is an older model. Upgrading an older model will not only fix any wiring problems but can also make it easier to make cooling your home more energy efficient. If you have a strong intention to resolve the issue on your own, here is a short checklist:
- Clean the filter.
- Clean the condenser coils.
- Adjust the thermostat settings and proceed to replace the thermostat if no change (Hint: it’s broken if it has no continuity when tested with a multimeter).
- Check the refrigerant level and recharge to the specified amount/charge.
- Troubleshoot the boards and see the one needing replacement (you usually need to replace them).
- Replace the Compressor . Remember that the run capacitor won’t have continuity once tested if dead.
If you’re not able to get the problem resolved with the above troubleshooting tips, have an experienced HVAC professional investigate further to identify the cause. Even if you are successful, it may be wise to upgrade from an older thermostat to a new programmable model, to avert future problems.
