If your AC is not working at all:
1. Make sure it is receiving power at the electrical panel.
2. Reset the devices’ switches and overloads.
3. Examine the thermostat settings.
4. Check the condensate overflow switch.
If your AC is not cooling but runs:
1. Switch off the power.
2. Tidy or change the air filter.
3. See if any ice formed on the coils and if YES, turn on the power and the fan to melt it.
4. Tidy the condensate drain.
5. Finally, check and tidy the outdoor compressor.
Although a qualified air-conditioning repair team ought to handle certain kinds of central air conditioner repair works, you’ll find approaches for managing primary repair works and upkeep yourself in this short article.
Central AC Not Working At All
1. Check the electrical panel and any secondary circuit panels for a tripped breaker or blown a fuse. If you discover the issue there, reset the breaker by turning it off and after that on or change the fuse. A central air conditioner usually links to a 240-volt circuit. If the switch continues to journey, believe a brief in the system– in the compressor, capacitor, or the fan motor. Employ an electrical contractor to find and solve this problem.
2. Make sure the thermostat is set to COOL, and its temperature setting is at least 3 degrees listed below the ambient space temperature level.
3. Ensure the power is on. Inspect the switch in the furnace or air handler and the outdoor condenser. Also make certain no one has shut down the compressor’s 240-volt disconnect, typically in a metal box installed near the compressor.
4. Remove the thermostat’s cover after turning off the power to the air conditioning system. Get rid of the thermostat’s body from the base (usually by pulling straight out) and change the batteries (if it has batteries). Ensure all wires safely connect to their terminals and that the cover will not pinch them. Replace the lid and wait 2 or 3 minutes, and then attempt the system again.
5. If that doesn’t work, open the thermostat and unscrew the wire from the Y terminal. Turn the power back on. Holding the wire by its insulation just, touch the bare end to the R terminal and hold it there for about two minutes. If the compressor boots on, the thermostat is defective; change it as we talked about in the short article on Ways to Install an Electronic Thermostat. If the compressor does not go on when you hold the Y wire to the R terminal, turn the power withdraw and either call an air-conditioning technician or examine the capacitor. hvacsystempros.com
6. Finally, inspect the compressor’s capacitor and wires. The capacitor in the compressor begins both the condenser and the fan. If the capacitor has stopped working, the A/C system will not run. It’s very easy to examine whether it works and it is cheap and pretty straightforward to repair if it doesn’t.
