Why is my AC constantly running?
A constantly running air conditioner is an indication of an underlying problem. Why? The system should work as per your initial setting. It means that once the temperature adjusts to the settings, it should stop to allow the unit to cool.
Any deviation from the said norm could be caused by:
A Clogged Air Filter
Dirt and dust will restrict airflow in the filter. As a result, the amount of air produced reduces, making your air conditioner run continuously. If not repaired, the AC air filter breaks down as a result of extensive wear and tear. Therefore, be sure to change the air filter at least once a month. Alternatively, follow the manufacturer’s recommendations.
Inappropriate Air Conditioner Size
The AC size should neither be too big nor too small for your home or business premise. An oversize unit will not effectively remove moisture from the air. On the other hand, a small AC will overwork to achieve the ideal temperature. Either way, your air conditioner will constantly run to meet the demands of your space. You will need a contractor to help you fix this by performing a heat load calculation, and then you can buy the right air conditioner.
You Are Having Air Leaks
Thirdly, your home or office could be having air leaks. Ensure that you check your duct, windows, and doors for any air leaks and have them sealed. Otherwise, conditioned air will continuously leave the premises. Next, the AC will run non-stop in an attempt to keep the temperature ideal (remember, you had already given it instructions).
Low Refrigerant Charge
Your AC could be constantly running because there is a leak in the refrigerant coils. This results in decreased refrigerant, which forces your air conditioning system to run non-stop. However, this is not a DIY procedure you can handle. Resolving it requires an expert to check the leak and fix it.
Dirty Evaporator Coils
Note that your air conditioner has an evaporator coil on the inside and the outside. The inside one absorbs heat from the air while the outside evaporator coil disperses heat outside. Dirt accumulation hinders the optimal performance of the coil by inhibiting the absorption and dispersion of heat. As your unit struggles to perform the two tasks, it ends up running non-stop. Therefore, schedule an air conditioner maintenance visit if you notice any accumulation of dirt.
A faulty thermostat will fail to register that your unit has achieved the preset conditions. If this happens, your air conditioner will continue to run. To troubleshoot this, place a thermometer near the thermostat and check the readings after an hour or two. If the readings rhyme with your settings, then the problem is the thermostat. Alternatively, check whether the device will come on when you set the temperature at 5° C lower or higher than your normal setting. Lastly, confirm that the thermostat is set to “Heat” or “Cool,” and the main circuit breaker is in the “On” position.
Worn Out Air Conditioner System
All machines and devices have a useful lifespan. Consider replacing an overly old unit with a new one. Doing so will save you from endless maintenance visits. A new AC is also efficient. Did you know that a high-efficiency system can help you save up to 20% on your cooling and heating bills? Either way, you will save some bucks.
Generally, lack of proper maintenance will cause your AC to run continuously. Besides professional visits remember to frequently check the system for any obvious issues such as dirt and leaks.
