Why Your Air Conditioner Might Overheat and Shut Down

Nobody wants to be stuck in a sweltering summer without a working air conditioner, but if you run yours frequently, that's exactly what you might end up with at the worst possible time. If you notice any signs that something could be wrong, don't wait until the system goes out completely to get things fixed. Here are a few situations that could cause you to need to repair or even replace your air conditioning systems.


Blocked Filter

As far as air conditioning repair goes, this is about the easiest to prevent and the easiest to fix--if you catch the problem soon enough. Your home's air filter needs to be changed regularly just like the air filter in your car's air conditioning system does. However, the air filter in your home runs a lot more than the one in your car, so it needs to be monitored far more often. If you leave your AC running for long periods of time, you'll want to confirm that your filter is clean at least once a month. Leaving the filter dirty can cause both poor air quality inside and cause the air conditioner to overheat, leading to repair problems.


Dirty Coils

Just like the filter, the coils can trap dirt as well, and this can cause big problems for your air conditioner. Dirt causes the system to overheat quicker and prevents it from operating at its maximum efficiency. Over time, dirt can even cause problems to the unit. If you've already checked your filter and it wasn't the issue, dirty coils might be the reason that your unit is having trouble doing its job.


Leaking Refrigerant

Have you ever discovered ice in your air conditioning unit in the middle of the summer? It's no accident. If the air stops flowing in your air conditioner, the system can overheat and won't be able to cool anything properly, which means that ice can form as the system struggles to do its job. If this occurs, your air conditioner is likely running low on refrigerant, which means that you have a leak in your system.


If your system starts leaking, the problem has to be fixed as soon as possible or the air conditioner can get damaged. If left alone for too long, the system can become covered with ice crystals, and you'll either have to hope the crystals melt enough without causing damage or purchase a new air conditioner. AC repair is almost always the cheaper option of the two, so the quicker you notice damage and call a specialist, the better.


These are just a few of the issues that can plague an air conditioner and cause it to overheat. What they all have in common is that if left unattended, any of them can require a new air conditioner. When you start to notice anything wrong with your AC, then commissioning AC repair can help preserve the life of your air conditioner and keep you cool throughout the summer.
