10 Reasons Why The Air Conditioner Is Not Cooling


If your air conditioner is broken, obviously there is a major problem that needs to be solved by a professional from Canada Energy Solution air conditioner repair. However, a slightly more complicated problem is when your air conditioner is working, but the air is not cold enough. Today we will discuss why your air conditioner is not cooling properly and what you can do to solve this problem!

  1. The cooling coil is dirty.
    Your air conditioner has a set of indoor coils that absorb heat from the air in your home and a set of outdoor coils that transfer heat from your home to the outdoors. If there is a layer of dirt on any of these coils, heat transfer between the coil and the air blowing through the coil becomes more difficult. This may greatly reduce the ability of your system to dissipate heat from your home, and the air coming out of the vent will be warmer than it should be.
  1. The refrigerant leaks.
    The refrigerant flows through the air conditioning coil and actually transfers heat from the indoor to the outdoor condenser unit. If your system has a refrigerant leak, it will not be able to sufficiently transfer heat out of your house. Your air conditioner will run, but it will not provide better comfort.
  1. The condenser unit is blocked.
    Canada Energy Solution home air-conditioning repairs stated that the condenser units are located outside, where they are blocked by plants, bushes and other shrubs. If your condenser unit is blocked, it will not be able to fully release heat from the condenser coil. This means that the heat removed from your home will not be released properly.
  1. Dirty air filter.
    When your air filter is dirty, the amount of air that can be blown through the evaporator coil is limited. When this happens, most of the hot air your air conditioner draws from the home will not actually be cooled.
  1. Compressor problem.
    The compressor of the air conditioner is responsible for ensuring that the refrigerant is at a better pressure, making it an important part of the unit. Without it, your system will not be able to absorb heat from the room in your home and transfer it outside. If it is starting to fail, your air conditioner will not be able to properly cool down your home.
  1. The system is too old.
    Canada Energy Solution central air conditioner repair said that when the air conditioner reaches the end of its service life, it will not be able to cool your home as it did in the past. This is just a natural fact of the life of the air conditioner, which is why it is important to replace your system when it no longer functions effectively.
  1. The thermostat setting is incorrect.
    If your thermostat fan setting is set to “on”, the air handler will blow air even if the system is not in the cooling cycle. Therefore, some air coming out of the vent will feel warm. You can adjust it by changing the fan setting to “Auto”. Another setting to check is whether your system is in “hot” or “cold” mode. The air conditioner will only turn on when the thermostat is set to “cold”.
  1. Are the curtains in the room closed?
    What many people don’t know is that the location of your room’s windows and air conditioner will also affect whether the air conditioner is cool.
    If your room’s windows are exposed to direct sunlight throughout the day and the heat is high, you must work harder to cool the room. For example, draw the curtains during the day to block the sun and prevent the sun from heating the room, so that the air conditioner can cool down faster and the effect is more obvious.
  1. Are your windows sealed enough?
    Check the seals around the windows to ensure that no hot air enters (or cold air does not seep out). If necessary, weather strips can be used to reseal the perimeter of the window.
    The windows of most residential units are equipped with heat-insulating panels, which can be placed on adjustable plastic side panels. But to maximize efficiency, you still need to use weather strips around the equipment. And always use the manufacturer’s installation and safety hardware.
  1. Does the air conditioner vibrate?
    The air conditioner makes a lot of noise, including the hum of the fan and the constant circulation of the compressor. These noises are normal. However, if you hear the vibration, it may mean that the air conditioner in your home is not installed correctly. It is recommended to read the installation manual or contact the after-sales service to troubleshoot installation problems.

The air-conditioning refrigeration system is a relatively complex system, generally composed of multiple subsystems such as compressors, condensers, evaporators, and throttling devices. At the same time, there are five kinds of substances in the system cycle: refrigerant, oil, water, air, and other impurities. The first two are necessary to ensure the normal operation of the system, and the latter three substances are harmful to the system, but they cannot be absolutely eliminated.
