The Most Common AC Problems

Your air-conditioning unit is an essential part of your home or office, especially during the summer months. Hot and humid days can feel unbearable without it, and days like these can cause the body to overheat and tire easily. Overheating may even result in heat stroke, a cause for alarm that has claimed numerous lives all over the world.

Your air conditioning unit is basically an appliance that exchanges hot air for cold air within the confines of the unit. This is done with the help of refrigerants and a set of coils. As with any appliance, your air conditioner is subject to wear and tear, and will require periodic maintenance or repair throughout its lifetime. Here are some common air conditioning repair problems that you may encounter.

Compressor failure

The compressor’s task it is to put pressure on the refrigerant and push it through the coils to carry out heat exchange. When the compressor stops working, your air conditioning unit will not be able to cool your house. Lowered pressure in the coils reduces the amount of refrigerant running through them, which in turn causes the compressor to run hot and eventually seize. On the other hand, too much refrigerant can choke the compressor and will cause it to fail.

Blocked Filter

A clogged or dirty filter is one of the reasons an air conditioning unit fails. Dirty filters decrease air flow through the system, eventually causing the air conditioning unit to freeze. Periodic cleaning of the filter or replacing worn-out ones can prevent this problem.

Thermostat Setting

The thermostat is responsible for setting the temperature the home or office. Keeping it away from direct sunlight ensures worry-free function. Its interior must be kept clean and it should be kept level to prevent any malfunctions.

Refrigerant leaks

When the coolant in your air conditioning unit starts leaking, the unit will not perform correctly and the temperature will fluctuate. Have your unit examined annually by a trained technician to ensure that the unit continues to run smoothly throghout the year. Teams of technicians should be comprised of seasoned veterans that have been with the repair company for a considerable length of time. They should be highly trained and must remain updated with the latest training and technology in the HVAC field.

Breakers or Fuses and Capacitor Issues

Often when a motor dies, the first parts the HVAC technician checks is the fuse or breakers. These parts prevent your unit from overheating by cutting out when heat builds up in the system.

In addition, the motors that power the compressor and fans will not work without capacitors. The run capacitor provides a series of jolts to keep the motor running while the start capacitor sends a jolt to start the motor.

Being knowledgeable about some of the basic issues with regard to how an air conditioning unit works may may result in fewer hot, sleepless nights and more comfortable rooms at home. Just make sure that the right service provider is selected to ensure that repairs flow smoothly. The choice of service provider could mean the difference between a quick fixerupper and a week without air conditioning in the middle of summer.
