Why Your AC Keeps Turning Off and On: Reasons for Short Cycling

Does your air conditioner keep turning off and on frequently? Then it experiences a problem known as short cycling. This problem can compromise your comfort level, leading to damaged units and higher electricity bills. So here in this blog, we will jot down the most prominent reasons why the AC unit of your home is short-cycling. Knowing the underlying reasons can save your money and help retain the indoor comfort of your home during the summer months. Get in touch with a renowned air conditioning maintenance company in Dubai to receive effective AC maintenance services.

The Definition of AC Short Cycling

AC short cycling arises when your AC unit keeps turning off and on rapidly without ever completing a total cooling cycle. A normal cooling cycle is 10-20 minutes long, while short cycling remains less than 10 minutes or even 5 minutes. You shouldn’t overlook short cycling because it prevents your AC units from cooling your home in an effective way. This can lead to enhanced energy consumption, higher electricity bills, and a higher demand for repairs on the units.

Top Reasons Why Your AC Units Keep Turning Off & On

So as of now, you may realise what AC short cycling is. Below are the five most common AC short cycling reasons that the majority of homeowners experience.

Clogged or Dirty Air Filters

The first significant reason for AC short cycling is a clogged or dirty air filter. If the filters in your AC units become clogged, airflow will also remain restricted. It can create difficulties for the AC units to circulate air. This blockage ultimately pushes your AC units to function harder to reach the intended temperature, potentially causing short cycling and excessive damage to vital elements. So, if your air filter becomes dirty, it’s always better to replace it with a new one. This is a crucial part of preventative maintenance. You can also schedule a filter examination and replacement by contacting reputable air conditioning maintenance companies in Dubai.

Low Levels & Refrigerant Leaks

Low-level and refrigerant leaks are another very prominent cause of AC short cycling. We all know that refrigerant is a vital element that absorbs heat from your home and transfers it outside. A problematic refrigerant can make an AC unit turn off and on frequently as it endlessly tries to achieve the set temperature. This puts excessive strain on the compressor and leads to complete system damage.

Oversized Air Conditioning Units

When it comes to air conditioning units, size is a pivotal factor. If your AC unit is excessively larger than required, it will cool the entire space too fast, shut off prematurely, and then restart again. AC short cycling means the AC units won’t function long enough to dehumidify the air properly. This can make your home uncomfortable and extremely humid. Get in touch with a professional for load calculation to decide the best unit size for your home. If your current unit is huge, you can replace it with a new AC that suits the overall size and cooling needs of your home.

Electrical Issues & Faulty Wiring

Many of us are unaware that problems such as malfunctioning electrical components, damaged wires, and loose connections can cause short cycling. This happens when the electrical flow needed for your air conditioner to function gets damaged or interrupted. As an outcome, the entire system could start short-cycling. Electrical problems decrease efficiency and pose serious safety hazards, including the threat of an electrical fire. Other damaged electrical elements, such as a faulty contactor or a failing compressor motor, can also lead to short cycling.

Malfunctioning Thermostat

Do you know that a malfunctioning thermostat can fail to retain the set temperature or even misread the indoor temperature? This can result in short cycling of the cooling and heating system. Some prevalent reasons behind malfunctioning thermostats are a dead battery, loose wiring, inappropriate placement, or the requirements of calibration for the thermostat. Older thermostats may also be less precise than newer models. Hence, it’s necessary to contact a reputable air conditioning maintenance company in Dubai that can resolve the issue by examining the thermostat and, as necessary, calibrating, rewiring, or replacing it.

Frozen Evaporator Coils

Another very prominent reason behind AC short cycling is frozen evaporator coils. If the evaporator coils of your air conditioning units become frozen, they can’t efficiently remove heat from your home. In turn, they start functioning over time by cycling on and off very frequently to retain the desired temperature. In such situations, an HVAC expert can quickly recognise the cause of the frozen coils and take steps to get your air conditioning system up and running.

Worn-Out or Faulty Compressor

We all know that compressor problems cause short cycling, as the compressor is responsible for distributing refrigerant throughout the entire system. Common compressor problems involve electrical problems, mechanical failures, and wear and tear. All these issues can render the AC compressor unable to retain the proper pressure levels. A faulty capacitor or contactor can even lead to compressor failure. Low refrigerant levels can overheat the compressor and lead to a complete shutdown. In such a context, a reputable company can help examine the compressor and run a pressure assessment to diagnose the problem.
