Why is My Air Conditioner Not Cooling the House?
Your air conditioner must work to provide you with the right temperature that your home needs. In Singapore, an air conditioner is highly important to cool the air and lower humidity levels to fight the sweltering heat. But what should you do if your air conditioner isn’t giving you your ideal temperature? When the temperature rises during the summer, it can be very uncomfortable if your AC unit isn’t cooling your home. The good news is that you can troubleshoot the problem and improve your air conditioner’s performance.
Reasons Why Your Air Conditioner is Not Cooling Properly
1. Your Air Filter is Dirty
One of the most common issues that causes an air conditioner to not cool is dirty filters. Aside from regulating the temperature, your air conditioner cleans indoor air through air filters. If these filters are not regularly cleaned or replaced, the dirt will clog the filter and hinder proper air flow. This also causes the evaporator coil to freeze, which blocks the cool air from getting into your room.
Get your air conditioner's filter checked and replaced. This will not only enhance your aircon’s air flow but will also help you maintain cleaner air quality. Make sure to clean your aircon filter regularly to prevent having the same issue. We recommend changing the filters every three months, and more often if you have pets at home.
2. Your Thermostat Settings is Incorrect
If you regularly clean your air filters and are still not getting enough cool air from your air conditioner, check your thermostat settings. An incorrect thermostat setting will affect the overall function of your air conditioning unit.
Solution: If the air isn’t as cool as it has to be, check your thermostat settings and make sure it is set to cool. Wait for a few minutes to see if the air is cooling. It’s also good to check if your thermostat needs changing of batteries if applicable.
3. The Indoor Unit is Dirty
Split type air conditioners have indoor and outdoor units that work together to give you the right temperature. Here’s how it works:
The evaporator from the indoor unit absorbs the indoor heat and transports it to the outdoor unit. The air condenser from the outdoor unit will then condense the warm air into cool air. Like a dirty air filter, a dirty condenser will not properly disperse heat and affect air cooling.
Solution: Clear away any bushes, leaves, dirt, or anything else that could prevent your condenser unit from doing its job properly. Give your outdoor unit proper room to breathe and function.
4. The AC Motor is Broken
Your fan motors experience a lot of wear and tear. One indication that your motor is faulty is when you hear buzzing sounds from your unit. This will affect your unit’s cooling ability.
Solution: Ask for professional help in troubleshooting and fixing the motor problems. Make sure your air conditioner unit receives regular tune ups to prevent major repairs.
5. The Air Conditioner Compressor is Damaged
The heart of your air conditioner unit is the compressor. A faulty air compressor will affect the entire unit’s ability to cool the air since it circulates refrigerant throughout the indoor and outdoor units.
Solution: A damaged compressor will need a professional replacement, which can be pricey. However, there may be minor problems that just look like a compressor issue. The best way to identify it is to consult with a professional.
6. The Refrigerant is Low or Leaking
An air conditioner works by using a refrigerant. If your refrigerant is low or leaking, your air conditioner will not cool the air properly. Hissing or bubbling sounds can be indications that your refrigerant is low or leaking.
Solution: Refrigerant issues shall be addressed by professionals.
7. Other Appliances in Your Home are Producing Excess Heat
Sometimes, the issue is not within your air conditioner unit but in your surroundings. If your room is filled with heat-releasing appliances or is exposed to direct sunlight.
Solution: During hotter days, we highly recommend using the right window treatment to block direct sunlight that can affect the performance of your thermostat. Turn off and unplug appliances when not in use.
