Air conditioners are considerably different from those used 25 to 30 years ago. This change has led the air conditioning units to be more efficient, more powerful, and more effective when it comes to cooling your house by lots of degrees, not just by a few.
Frozen Evaporator Coil
If your air conditioner is not cooling properly, it could be due to a frozen evaporator coil. It is a common problem with home air conditioners and occurs when your unit does not receive enough air to operate normally due to debris build-up.
The dirt accumulated on the coils restricts the airflow, and warm air does not reach the refrigerant. In this case, the refrigerant becomes too cold, and any moisture on the coils freezes. Over time, the coil encased with ice, preventing the refrigerant in the coil from absorbing latent heat. This AC problem disrupts smooth air conditioning in your home.
To diagnose this problem of AC and Heating system, first inspect the damage. Then let the evaporator coil thaw (defrost). This can done by not using your unit for 24 hours or so—just make sure you disconnect power first! The evaporator coil usually takes 24 hours to thaw completely—but if you want to speed things up or don’t want to wait around for days (or just need some extra time for that next batch of cookies), use a hairdryer (on low) to help melt away that frosty goodness!
One of the most common AC problems is a damaged compressor. The compressor helps refrigerants carry out heat exchange and regulates the AC pressure. You notice that your air conditioner is not cooling properly, it could be due to a dirty coil, changes in refrigerant levels, or lack of lubrication.
If there’s not enough refrigerant, the compressor will become hot and stop working. There is more than required, the excess refrigerant will lead to increased pressure in the unit, which can also cause it to fail. If you believe your air conditioner’s compressor has failed, contact your local air conditioning service to solve this common AC problem. There is severe damage, it is better to replace the compressor instead of performing air conditioning repair.
If your air conditioning unit starts and stops abruptly, accompanied by a clicking sound. It could be a sign of capacitor failure. A capacitor is an important part of your air conditioning unit. And is responsible for giving the motor an initial push to start working. In the extreme summer heat, when your AC has to work hard, the capacitor can overheat. Also, power fluctuations and frequent changes in the thermostat setting can damage your capacitor. Contact a professional to get capacitor checked. Unfortunately, you cannot repair or replace it on your own as there is a risk of an electric shock.
One of the most common problems with home air conditioners is the thermostat malfunctioning. For example, if your air conditioner short cycling and your space feels warmer than usual, a faulty thermostat to be blamed. There might be a serious issue due to dust and corrosion build-up or a simple case of dead batteries. Loose screws or wires inside the thermostat can also affect its functioning. If you have placed your thermostat where it gets direct sunlight. It can If you have a battery-operated thermostat, check if the batteries are working fine. To solve dirt build-up, remove the cover and take a soft brush to clean any dirt. If you notice a corrosion build-up, contact a professional as cleaning it on your own can lead to more damage. Moreover, check the placement of your thermostat; it recommended to place it in a room that you use frequently and move it to a shaded area.
