Most Common Air Conditioner Problems

The Link Between Air Conditioning and Humidity Control

For central air conditioners, the most common problems include the compressor, relays, and contactors. These components usually fail when your rooms are shut and airflow is restricted through your home. However, for a room air conditioner, the situation is reversed. To avoid problems, you should shut the windows and doors in the room and other connected rooms when the air conditioner is running. Other reasons why your air conditioner can malfunction include poor installation, unprofessional service and lack of maintenance.

When your central air conditioner is poorly installed, you can face problems of poor airflow and leaky ducts. The refrigerant charge may also be incorrect, which can damage the compressor. It has to match the manufacturer’s recommendation. Incorrect refrigerant charging at installation can affect the efficiency and performance of your AC. Unlicensed service technicians usually miss refrigerant charging issues. They can even worsen the problem by adding the wrong refrigerant or too much of it. Save yourself plenty of problems by working with a professional AC company that employs licensed HVAC technicians. Air conditioners also need regular maintenance to function properly.

Most common problems arise when the air filter is not changed regularly, coils are not cleaned and refrigerant levels are low.

These simple maintenance tasks can make a big difference in how your AC functions. Air conditioners are built to last using top-quality materials that last. If you notice problems with your unit, it may be a circuit breaker or fuse issue. Check them before calling a technician. If you do need to call a professional, get the experts at DeZiel Heating & AC. Before you reset the breakers, always let the AC cool down for at least 5 minutes. If on a hot day your central AC’s compressor suddenly stops working, it could be due to a tripped high-pressure limit switch. To reset it, push the button. You’ll find it in the compressor’s access panel.

Refrigerant Leaks

An air conditioner that is low on refrigerant may be leaking or was undercharged during installation. If the problem is due to a leak, it is not enough to simply add refrigerant. You will need to find and repair the leak before adding any more. If you are not sure where the leak is, a trained technician will be able to quickly find it and repair it. Refrigerant leaks should be fixed as soon as possible as they can be harmful to the environment. For your unit to function efficiently, the refrigerant should not be undercharged or overcharged. It should meet the manufacturer’s recommendation. Poor Maintenance

Lack of Maintenance

Lack of maintenance is another common cause of air conditioner problems. Your AC needs regular cleaning and tune-ups to function properly. Dust and dirt can clog the filters and coils, reducing airflow and making your AC work harder. This puts extra strain on the compressor and other components. It can lead to early fan or even compressor failure.

Electric Control

Failure One of the main reasons for compressor and fan controls wear out is repeated turning on and off of your air conditioner. This often happens when your unit is too big for the space it’s meant to cool. Wire and terminal corrosion can also cause electric control failure. If your AC is frequently cycling on and off, it’s a good idea to have a trained technician take a look at it. All electrical connections and contacts should be checked during a routine professional service call.

Drainage Problems

On humid days, you may notice water pooling around your air conditioner. This is normal and nothing to be concerned about. The condensate drain is there to remove any water that condensed on your unit’s coils. If the drain pan fills up or the drain line becomes clogged, it can cause water damage. To prevent this, the condensate drain should be checked regularly.

Sensor Problems

Room air conditioners have a thermostat sensor. You’ll find it behind the control panel and it’s function is to measure the air entering the evaporative coil. This sensor should be close to the coil but it shouldn’t actually touch it. Sometimes, the sensor can be pushed out of position. When this happens, your unit may malfunction or cycle continuously. To solve this problem, simply adjust the sensor back into place. To do this, bend the wire that keeps it in place. If your air conditioner is not working properly, it may be due to one of these common problems. Before you call a technician, check to see if the problem is something that you can fix yourself.
