Why Does My Air Conditioner Turn On and Off Frequently?
In Singapore, air conditioners are a need more than a luxury. When the weather reaches its uncomfortable level, the cool breeze from the air conditioner makes staying at home more convenient. That’s why we don’t want any malfunctions to happen.
If your air conditioner keeps on turning on and off by itself, it could be going through what we call short cycling. A short cycle occurs when the cooling cycle is shorter than what it intends to be. This can cause the AC compressor to turn on and off more often. This premature turning on and off can wear your compressor more often and may cause damage to your unit in the long run. There are many factors that you should check to find the root of the problem. Don’t panic because when the problem is detected at an earlier stage, you can avoid damage and costly repairs.
What Causes Your Air Conditioner to Turn On By Itself?
Thankfully, not all air conditioner issues are fixed by repairs. Sometimes, the short cycling is caused by incorrect thermostat settings, which can be easily corrected. If your AC unit is turning on by itself, check your thermostat and set the settings according to your room’s requirements. Also, make sure that the batteries in your thermostat are working.
Inaccurate Thermostat Readings
Your thermostat may read the temperature of your room inaccurately and may cause fluctuations if it is positioned near heat-producing appliances or direct sunlight. If your thermostat is positioned near the window, you may use some blinds or curtains that are thick enough to prevent direct sunlight from affecting the thermostat.
Dirty Air Filter
A dirty air filter restricts the airflow of your air conditioner and affects its ability to clean the air. If the air filter continues to be clogged, the coils may freeze and cause short-circuiting. Regular cleaning or changing of your air filter will go a long way in protecting your air quality and the efficiency of your air conditioner unit.
Dirty Condenser Coils
Your condenser is located outside, which makes it prone to receiving direct sunlight, dust, and other debris that can affect its quality. Dirty condenser coils may overheat and struggle, which can cause more damage. The best thing to prevent this is to conduct regular cleaning and maintenance.
Air Conditioner is Too Big for the Space
In terms of buying an air conditioner, bigger is not always better. If your AC unit is bigger than what your room needs, it will also be too powerful and will cool down your room quicker. This will cause the unit to shut off quickly even after turning on. This may not help in addressing the humidity in your area and may cause your air conditioner to wear out faster.
Different room sizes have various air conditioner requirements. When shopping for an air conditioner, it’s worth understanding what the best size will be to fit your room's requirements.
The refrigerant is an important part of the air conditioner. Leaks from your air conditioner are not part of the cooling process. Instead, refrigerant leaks may cause bigger problems, even for your health. If your AC unit is low on refrigerant, the compressor will malfunction and turn on and off prematurely.
Refrigerant leaks must be fixed by professionals as they can be dangerous.
Faulty Air Compressor
A faulty air compressor can overheat and cause your unit to turn on and off frequently. We highly recommend seeking professional assistance once you notice your air compressor turning on and off every two to three minutes to avoid frequent wear and tear.
Your Air Conditioner Needs General Cleaning and Maintenance
Dirty air filters, faulty air conditioner parts, and other issues can be avoided with regular air conditioner maintenance. HVAC professionals run thorough inspections to make sure that your unit is still running at its prime. Repairs and tune ups can also be done promptly to prevent bigger damage.
The constant shutting off and turning on of your air conditioner can increase your energy consumption and put a strain on your air cooling system. Is your room not cooling down anymore? Is your electricity bill rising? Short cycling might be the reason. Spot the problems as early as possible to save you money and prevent future hassles.
