Around the world, temperatures are soaring. So much so that in England this November, a country synonymous with grey, wet weather, they are experiencing a so-called ‘Indian summer’ heatwave. In times like these, with temperatures on the rise, air-conditioning units are more needed than ever. Air-conditioning units, however, like every piece of tech equipment, can break down and stop working. It is essential that should your air-conditioning unit begin to fail you that you identify the problem and resolve it quickly, lest you be caught in the midst of a heatwave.
This page will tell you seven probable reasons why your air-conditioning unit is not working so that you can properly identify the cause of your air-conditioning unit’s failure. Let’s find out what those seven are, shall we?
The water and moisture that your air-conditioning unit removes from the air have to go somewhere; that somewhere is in your drain. Quite frequently, blockages occur in the drainpipes of your air-conditioning unit. When this happens, it can be a mild inconvenience, for your unit can briefly stop working. It is easily repaired, however. When searching for tradespeople to unblock your drains, only hire the best. You can gauge the professionalism of a tradesperson by reading their customers reviews thoroughly. That said, you may even be able to repair it yourself, although this is not recommended, for you could damage your unit irrevocably.
Your air-conditioning unit’s evaporator coil is filled with refrigerant, which absorbs heat from the air. These coils need warm air to work properly, despite the fact they themselves are cold. However, when the airflow around your evaporator coil gets too cold, ice can build up on the outside of the coil, which means you will only get warm air [if any] coming out of your air-conditioning unit. This is a job for a technician, and it is best you do not attempt to repair this yourself, for you can damage your unit.
As mentioned in the previous paragraph, the refrigerant absorbs heat. If your air-conditioning unit develops a leak in the refrigerant lines [which can happen and does], you can wind up with there being too little refrigerant in your unit, and not enough to cool the air. Unfortunately, this is not just a matter of draining and replacing your refrigerant, and rather, a trained technician will need to come out to identify, treat, and repair the leaks. It can be very expensive, so it is best not to attempt it yourself, lest you cost yourself more money.
Your unit’s condenser coils can get dirty quite easily. The condenser coils, which are based outdoors, remove indoor heat by pushing it outdoors. Dirt and grime can quickly accumulate, courtesy of air pollution and dust. When your coils become dirty, heat transfer cannot work, which means your unit is forced into overdrive. Over time, if not treated, your unit can begin to break down completely and may need to be replaced.
The fan inside your air-conditioning unit blows indoor air over your unit’s evaporator coil to cool the air; another fan blows outdoor air over the condenser to push out the absorbed indoor heat. If either of those fans begins to break down, whether it be because of dirt, a faulty motor, poor lubrication, or worn-down belts, you can end up having very poor airflow and air-conditioning unit problems. This problem, over time, can contribute to compressor and motor failure, which cannot be repaired, and will mean you need to completely replace your air-conditioning unit.
The ductwork that runs through your home and distributes cool air can develop holes, through the negligence of the installation team, or rodents and birds. That air can wind up in the walls of your home, which will not keep you cool, nor benefit you in the slightest. This will mean your air-conditioning unit has to work much harder to cool your home and will be a detriment to your energy bill. To save yourself money, if you notice the air not distributing freely, contact a technician to identify whether or not there is any leaks or holes in your ductwork.
Mould, Dirt, and Grime
Mould, dirt, and grime can build up inside your unit if not cleaned regularly. While this will not impede your unit’s performance, it can be a detriment to your health, and it can make you very unwell. If you notice allergies or illness occurring when your unit is on, then it may be time to give your unit a deep clean.
With the help of this page, you now know a few ways to identify and solve problems with your air-conditioning unit. Air-conditioning units a great way to keep cool during long, hot summers, but only if they are working!
