The 5 Most Common Air Conditioning Problems
Posted on 18th March 2019 by FM Mechanical Ltd
Annoyingly, it’ll be the hottest day of the year when you realise that your air conditioning has stopped working. A poorly maintained system can cause it to perform poorly, making it inefficient and more expensive to run. Here are a few reasons why your AC may not be working correctly.
Common Air Conditioner Issues and How To Fix Them:
Dirty or Clogged Air Filter
A dirty or clogged filter can restrict the airflow to the unit and even cause it to freeze. If you haven’t cleaned the filter for a considerable amount of time, then do so now. The filters on central AC units should ideally be changed once a month, especially if your unit is in constant use or you have pets.
A good way to check if your filter is dirty is to see if any light passes through it, if not, it’s time for a clean.
Dirty Condensor Coils
Condenser coils are located outside, leaving them vulnerable to the elements. When they get dirty, they can be cleaned with a water hose once a year. However, if they get too dirty, you may need one of our experienced technicians to solve the problem with a chemical cleaner.
The compressor is an integral part of any AC unit. It applies energy to the refrigerant, propelling it through the coils to carry out heat exchange. When this process stops, the AC unit will fail to cool your house. Check how much refrigerant there is, if there’s not enough, the compressor will run hot and subsequently seize. If there’s too much, the refrigerant will eventually return to the compressor, causing it to fail.
If in doubt, always seek professional help and advice. It is advised not to take out substantial repairs yourself as you could damage your unit or harm yourself.
Much like the filter, a drain line can easily become blocked with grime. If it clogs, the drain pan could fill up, allowing water to leak. This could cause irreparable damage to your AC unit or objects around the pan.
To prevent this from happening, regularly check on and clean the drain line. If you can’t pinpoint an obvious problem, it is advised that you call one of our qualified professionals to help you carry out any repairs.
Often, when this happens, it can be linked back to the breaker or the fuse. Breakers and fuses safeguard the unit’s motor and stop the compressor from overheating. When you call one of our friendly engineers, the first thing they’ll often check will be the breaker.
When the coolant starts to leak in an air conditioner, the unit won’t perform correctly, subsequently causing the temperature to fluctuate. Depending on the location of the leak, it could be relatively expensive to fix. It is advised that you have a technician examine it once a year.
