The ten most common air conditioning problems you need to know about:
1. Air conditioning system making loud noises
Air conditioners can make different noises depending on the existing problems it experiences. Here are a variety of reasons why your air conditioning system is producing loud noises:
- Malfunctioning electrical components produce the buzzing sound.
- The rattling, banging noises, and thumping can be the cause of a problem with your motor assembly or blower.
- The compressor makes screeching noises.
- If your air conditioning system is experiencing a refrigerant leak, this can partake in a hissing sound.
Relay problems might occur if you hear a clicking sound when you turn on and off your air conditioner
2. The evaporator coil is frozen
Your air conditioner’s evaporator coil might experience freezing if there is an inadequate system airflow going on. If there isn’t enough air blowing over your evaporator coil, then it won’t have enough heat to absorb, causing the condensation on the evaporator’s coil to freeze over. A frozen evaporator coil can make your air conditioning equipment freeze up and stop working. This occurrence can be due to anything from blocked vents and ducts to malfunctioning air handlers, or freon leaks so you better keep an eye on that to avoid this situation.
3. Problem with the drainage system
Just like your air conditioner’s air filter, drainage can suffer from clogging – numerous build-ups of dust, dirt, and even algae. Moreover, if the water does not drain properly, there is a potential possibility of mildew, fungus, and mold developing, causing the gasses and unpleasant odor to infiltrate your home. For you to prevent this, the first thing you should do is to make sure that the drain line is properly cleaned, maintained, and inspected. One cup of bleach or white vinegar a month can help with drain clearing.
4. Thermostat Sensor Problem
The thermostat sensor is located near the evaporator coil of your air conditioning system. The thermostat is the one that controls the temperature setting inside of your home and turns the system on and off as needed in order to reach the desired temperature. If the sensor is not leveled properly and the inside is not clean, the air conditioning system can randomly turn on and off. To avoid this kind of problem, make sure that the sensor is in the correct setting and of course, clean.
5. Dirty Air Filter
One of the most common reasons why the air conditioning system does not work effectively and efficiently is due to a clogged and dirty air filter. Given enough time, the build-up of dirt in the air filter can contribute to serious problems not only to your air conditioning system but as well as your health condition. Therefore, make sure to follow the manufacturer’s suggestions regarding how often and when to change and clean your air conditioner’s air filter. Typically once per month.
6. The air conditioner won't turn on.
In general, if your air conditioning unit is not turning on, it is probable cause that the circuit breaker has been tripped. The first thing you must do when this thing happens is to reset it after locating the circuit breaker panel. But, if you still find that your air conditioner does not work or turn on, the next cause might be in your thermostat. If so, check the batteries of your thermostat and replace them if they are already dead. If the thermostat batteries are in working condition, try checking the setting whether the cooling temperature is in your desired settings.
7. A refrigerant leak in the air conditioning unit
If the air in your home is not as cold as it used to be, a common problem is a refrigerant leak. This problem is caused by holes or cracks in the coils which is where the refrigerant circulates. Refrigerant leaks can result in:
- Hissing sound in the air conditioning system
- The freezing of evaporator coil
- A damaged compressor
- Uneven cooling in the entire house
- High consumption of energy
If the problem continues, you must call your nearest 24-hour air conditioner repair to help you with the refrigerant leak.
8. The air conditioning unit is not blowing cold air
If your air conditioner is not blowing cold air as it should, try cleaning the air filters and the coils and then see if improving the airflow fixes the problem you are experiencing with your unit. However, if there is a possible ice build-up, you could run your air conditioning system with just the fan to melt the ice off. If this still doesn’t get the air conditioner blowing cold air again, you might want to try checking the refrigerant levels of your unit to see if they are low or empty.
9. Condenser Coils Problem
If your air conditioner is experiencing condenser coil issues, you will begin to notice some warning signs including:
- loud and abnormal noises coming from the air conditioning system
- a leak in the coolant of your air conditioner
- significantly reduced the cooling capability of the unit.
10. Electric Control Failure
Fan control and compressor of the air conditioner can wear out, specifically if your unit is in frequent turning on and off. A connection problem can prevent the air conditioner’s motor from turning on. Thus, you should check the electrical connections to determine the issue, especially during a professional service call.
