If your AC unit continues to run even after you’ve shut it off, there may be a serious issue that’s driving up your energy bill. One possible explanation is that the fan is set to “on,” the thermostat is malfunctioning, or the air filter is clogged. The fan relay or control board could be at fault.

Problems can arise with even the best air conditioners, so it’s important to schedule regular maintenance and repairs. Put in a call to the experts! If you’re looking for reliable air conditioning service in, go no further than airconservicing.org.

1. Power Fluctuations:
There are a few potential electrical problems that could arise with your air conditioner. A jammed relay switch or faulty wiring are two possible explanations. The power supply to the system is managed by a relay switch. It causes the circuit to remain closed when stuck. This means that the air conditioner receives power continuously, which can increase the frequency with which it operates and the associated expenditures.

Meanwhile, the system is controlled by wires, and electricity is carried to your unit by wires. The length of time the unit operates for can be affected by poor wiring or loose connections. Similar to other parts, wires can become worn and damaged over time, necessitating repairs. Is that’s the case, you should contact marvellous.sg.

2. Thermostat Problems:
One typical reason for air conditioners to keep running after being turned off is a broken thermostat. You may programme the thermostat to your desired temperature, operating mode, and fan settings. The air conditioner can be turned off automatically based on the readings from temperature sensors installed in each room.

Old thermostats, especially those older than ten years, have a far higher failure rate. The likelihood that these life-sustaining tools will fail to function properly grows with age. Here’s when you might want to think about upgrading to a new thermostat.

The accumulation of dust on the temperature sensor can also be problematic, as it would result in an incorrect measurement. It’s possible you’ll feel like the actual temperature in your house is lower than the one you’ve set the thermostat to. This problem could cause the air conditioner to cut off unexpectedly.

3. Thermistor:
The thermostat relies on the thermistor for accurate temperature readings. The thermistor acts like a thermostat in that it controls the on/off status of the condenser. If your window AC unit remains running even after you’ve shut it off, a faulty or broken thermistor could be to blame.

The first thing you should do is open up the air conditioning unit and see if the sensor is faulty or unplugged. Use your multimeter to inspect the relay board and other parts of the Electronic Control Board of your air conditioner while you’re at it.

4. Ineffective (Undersized) Air Conditioner:
This issue is not technical in nature, as opposed to the ones we’ve already discussed. In most cases, this is because you bought an air conditioner that is too small for the space in question.

Because of this, your air conditioner won’t stop running even after you’ve shut it off because it’s trying in vain to maintain a comfortable temperature. If this is the case, your only choice is to upgrade to a more robust AC unit.

When deciding on an air conditioner for your home, efficiency and sizing are two crucial factors to consider. Choose wisely and you won’t have to second-guess yourself. If you’re experiencing other issues with ventilation, it could be because your air conditioner is too small.

5. Extreme Temperatures:
Extreme heat can be detrimental to your health if your region is experiencing a heatwave. If your thermostat is functioning properly, it will have a predetermined temperature and activate your air conditioner if the desired temperature is not being maintained.

Your air conditioner may be on for extended periods of time if it is continually working to keep up with the demand. Find measures to reduce the temperature within your home if this problem persists. If you keep your blinds open during the day, make sure to shut them when the temperature outside rises.

This can reduce the workload on your AC unit. Getting some blackout curtains is a further piece of advice. These do an excellent job of blocking out the sun, which is great news for your air conditioner. A properly functioning air conditioner has additional benefits, including reduced energy costs.
