An air conditioner should be well-maintained to ensure its smooth performance at all times. If your home is equipped with air conditioning, it is important to be prepared for some of the typical ac repair and service problems that may arise at any point of time.
- Dirt in the Air Filter
This is a common problem with air conditioners. A dirty air filter can compromise the efficiency of your air conditioning system. It is easy to detect this problem if you keep checking it on a regular basis. Changing the filter once a month (in the summer, depending on how much you are using it) is a prudent idea because a malfunctioning filter can lead to poor air quality, apart from reducing the system’s efficiency.
You should change it once in the winter too depending how much you use your heater. So you could change your filters about three times a year total. You can also reuse filters if you wipe them down with a damp cloth. You can obtain another two to four months of use perhaps this way depending on how much you use your system.
- Leaking Refrigerant
The refrigerant is the vital material that helps cool the air coming in from the air conditioner unit. Leakage of refrigerant is a common problem in air conditioners, and lack of refrigerant can cause ineffective cooling. Even a small leak in the unit will cause gradual depletion of the refrigerant. Refilling it to the proper level can resolve the issue.
- Dripping Water
An air conditioner that is functioning properly should not leak water at any time. The condensation formed in air conditioners has to be effectively removed to ensure the appropriate functioning of the system. This is done with the help of a condensate pump. It is likely that a drain pipe or the condensate pump is at fault, if you start noticing droplets of moisture. This could happen due to dirt or algae clogging the pipe or the pump.
- Noisy Operation
One indication that something is wrong with your air conditioner is the strange noises that emanate out of it. While a problem with the belt might be the cause of a high-pitched squeaking sound, pops and cracks are likely to indicate that something in the duct system has been loosened. Problems with the motor are likely to cause a grinding sound.
- Thermostat Malfunction
There are many things that could go wrong with your air conditioner thermostat. You might have set the thermostat at your preferred temperature, but if you find the temperature going up or down, then it might be time to take a careful look at the thermostat. The electronic circuitry may be old and causing the malfunction. Exposure to direct sunlight and proximity to other appliances can lead to overheating of the thermostat, which could also result in a malfunction.
- Unit Does Not Switch On
Sometimes you may find that the air conditioning unit simply does not switch on. This can happen if the thermostat is not set to the correct temperature, and also if the battery of the thermostat has a problem. A dead battery means your air conditioner will not turn on. A tripped fuse in the circuit breaker can also be the cause behind your air conditioner not switching on.
- Lack of Cooling
You had switched on your air conditioner a while ago, but the desired level of cooling has not occurred. This could mean that your air conditioning unit has developed a problem that needs to be addressed. It could be that the refrigerant needs to be replenished. Sometimes poor cooling may also occur due to some type of blockage to the exterior unit. A problem with the compressor or a dirty air filter can also lead to decrease in the cooling effect.
- Unit Does Not Turn Off Automatically
An air conditioner usually turns off the air when the room is cooled to the required temperature. When this does not happen, it can be a cause of concern. The thermostat is the first suspect. It might be that the numbers are not being displayed correctly on the thermostat. An electrical problem with the outdoor unit of your air conditioner can also cause this. It is possible to switch off the air conditioner with the breaker switch, but this may not be a lasting solution.
- Unusual Spike in Electricity Bills
Keep an eye out for sudden increases in your utility bills, as this can also be caused due to problems with your air conditioning. The air ducts might be blocked by damaged insulation or there may be holes in the ducts that are causing a dip in the quality of air inside your home. The increase in monthly electricity bills might also be the result of a dirty air filter.
Your system is working harder than it should to keep your home cool or warm depending on the setting because your air filter is dirty. This is not ideal.
- Air Conditioner Keeps Turning On and Off
When this happens, it is called ‘short cycling’ and there are quite a few causes. The condenser coils which give out the heat from the refrigerant can get dirty leading to this problem. A dirty air filter or leak in the refrigerant can put stress on the unit, causing it to turn off and on. This issue can manifest itself if the unit is located close to a window or another appliance that causes it to heat up more than it wants too.
