If your main air conditioning system instantly losing cooling power, you may be able to repair your unit yourself, and in many cases also take care of the trouble without calling an expert. Knowing a little regarding your home AC system will make repairing less complicated. Troubles can occur in any of the significant components of the system:
- Cooling agent
- Evaporator coil
- Expansion valve
In addition, there is the “mind” of your cooling and heating system, the thermostat, which can also be a concern sometimes.
The location to start, however, is with the symptom of the breakdown.
If the AC System Will Not Turn On
If you cannot get the AC system to trigger in all, then amongst the most common reasons lie with a stumbled breaker or blown fuse, an improperly established or malfunctioning thermostat, or an internal switch being off.
- Make certain the thermostat itself remains in the TRENDY setting as well as not established to WARMTH or OFF.
- Verify that the thermostat is established below the current area temperature.
- Check to make that the 240-volt circuit breaker, or double-pole breaker, controlling the air conditioning condensing/compressor system and the 120-volt breaker managing the heater blower or different air trainer remain in the ON settings. When a circuit breaker gets tripped or else a fuse gets blown, then you should reset the circuit breaker or replace the fuse. If you reset the breaker or replace the fuse and they trip or impact again, quit as well as call an air-conditioning service technician, as you might have extra serious trouble, such as a brief circuit.
- Validate that all switches in and around the air conditioning system are set to the ON setting, including the outside safety switch, which is normally found on an outside wall surface beside the condensing unit.
- Inspect the condensate overflow tray, if your system has one, for excess water. Often this tray is mounted in remote air trainers that use condensate collection as opposed to a condensate drain pipe. When using a tray, there may be a sensor switch that turns the system off when water gathers in the tray.
- Check that the blower door over the air trainer is nicely shut. This is located indoors, on the primary heater blower system.
If still your system not working properly, then call a professional urgently.
