Air Conditioning Troubleshooting

7

If your air conditioning unit is blowing hot air, you might want to check the thermostat. Make sure the setting is relaxed or auto. If it’s set to heat, the air will be too hot. Check the air filter, too. In some cases, a dirty filter will lead to hot air.

A clogged air filter is a significant problem with your air conditioning system. It can lead to inefficient cooling, a poorly working furnace, or even a breakdown of your whole HVAC system. Changing the air filter is a preventative maintenance measure that will help you save money on energy bills and extend the life of your system. A clogged filter can also lead to an overworked blower and costly repairs.

When your air filter gets clogged, dust and other debris can circulate back into your home. This can be dangerous for people with allergies or respiratory conditions. Additionally, poor air quality can negatively impact your overall health over time.

Blowing fuse

If your air conditioner is not cooling correctly, it might signify a blown a fuse. While this problem doesn’t necessarily mean that you need to replace the whole air conditioner, you should contact an HVAC technician for an inspection. Several different factors can cause the problem. For example, a dirty condenser coil can prevent air conditioners from losing heat as efficiently as possible, or a weed whacker may cut the wire from the thermostat to the condenser. In either case, you should turn off the power switch and check the fuse carefully. If there is no fuse, you may also need to check the electrical circuit of the air conditioner to see if it’s a problem.

Fuse failure is one of the most common problems with air conditioning systems. When a fuse blows, the air conditioner will stop working. There could also be a faulty component, such as a dirty coil or filter. A failed fuse may also mean the airflow is inadequate, which may cause an overvoltage incident.

Faulty tubes

Fortunately, there are some simple methods for diagnosing faulty tubes in your air conditioning system. First, check the getters, which are located near the top of the tube housing or on the side or bottom. If they are grey, silver, or metallic chrome, that’s a good sign. If the getter is black, there’s a good chance the tube is faulty, but don’t panic.

A faulty orifice tube will affect refrigerant flow into the evaporator, and this will cause the AC system to operate inefficiently. Another way to check if the tubes are faulty is to use the ‘tap test. This involves tapping the tubes individually to hear if there’s any difference in sound.

Clogged condenser

There are several ways to clear a clogged condenser. The most common way is to use a plumbers snake, shop vacuum, or wet vac to remove the blockage. Once you’ve cleaned out the blockage, test the drain by pouring water down it. If water drains freely, you’ve cleaned the condenser. If water is still leaking, seek professional help.

The condenser drain line may become clogged due to dirt, algae, or mold. It can also get clogged due to improperly installed drain piping. Regardless of the cause, clogged condensers can cause malfunctioning of your air conditioning system.

Lack of power

When troubleshooting AC problems, you may notice that the power goes out when you try to turn on the AC. This could mean that there is a problem with the cooling system. Check to see if the vents’ air is lukewarm or cold. If it is not, there may be other problems with your AC system. These could include faulty wiring or vent flaps.

One of the first things to do if you encounter this issue is to check the transformer. You can buy one for less than $20 and try to diagnose the problem. It’s essential to check the voltage and current of the transformer and the AC panel. If the voltages don’t match, you can change the transformer.
