While no one expects their air conditioning unit to break down or cause them problems, it is something that you should be prepared for. Hopefully the brand you choose to invest in will be reliable and not give you too many problems, but it is worth knowing what to keep an eye out for should the worse happen.

There are a number of things that could go wrong with your  unit, but 4 of the most common air conditioning problems that you could come across include:

Inside Coil Frozen

If you find that your air conditioning unit isn’t getting as cool as it should be, or that it is unreliable then this could be down to the inside coil being frozen. Although this can seem like quite a major problem it is something that happens quite often and is relatively easy to fix. An inside coil being frozen can be caused by an unclean air filter or a blocked return air ductwork. If you notice that this does start to be a problem then the first thing you need to do is switch of the system completely. You can look at getting a professional air conditioning company in to help with this but cleaning out the air filters could be a good place to start before you go down this route.

Faulty Wiring

If your air conditioning unit seems to be cutting out or experiencing power surges then this could be down to faulty wiring. If the wiring inside the system becomes damaged then this will result in the unit being able to get a consistent flow of power to keep it working as it should. This is definitely something that you should get a professional to look at, because it could be dangerous and even a fire hazard.

Low Levels of Refrigerant

Freon, the refrigerant in these systems is what is used to cool the air. If you find that the air is not getting as cool as it used to then this could be caused by low levels of refrigerant. If this happens then the likely cause is a leak and this is something that needs to be looked at. It can seem tempting to simply try and top of the levels of refrigerant by pouring more in, but this is not usually the answer – after all, if there is a leak then this will just continue to cause you problems.

Exterior Fan Not Working

The exterior fan has the important job of moving the heat from your room to the outside. If you find that your air conditioning unit doesn’t work properly or starts to overheat then this could be the cause of the problem. This is probably not something you can fix yourself unless you have air conditioning experience, but it is worth getting an expert to take a look and see what they can do for you.

Of course other issues can (and will) arise surrounding your air conditioning unit, but these are the 4 that you should definitely be keeping an eye out for!
