Temperatures are slowly warming up around the country, so many people will be using their air conditioners soon. However, you might not know when your air conditioner may suddenly stop working on one of the hottest days of the year. The good news is that there are signs to look out for.

Here are a few signs that you may need AC repair. 

Your Air Conditioner Is Blowing Warm Air

An air conditioner's main purpose is to deliver cold air throughout your home. However, if your air conditioner has a broken part, it cannot do its job properly. If you notice that your air conditioner is blowing warm air, something is wrong. It might be low on refrigerant or there is a duct problem. Either way, you should call a professional as soon as possible.

Your Air Conditioner Is Making Funny Noises

Air conditioners should not produce much noise at all. If your air conditioner has been making funny sounds lately, it may be time to enlist the help of a professional. For example, if there is a squealing noise, the fan belt may be broken. If you hear a gurgling noise, there may be an issue with the condensation line.

There Is Too Much Humidity in Your Home

An air conditioner is also supposed to lower the humidity levels in your home. If it does not do that anymore, your air conditioner needs to be repaired. Too much humidity will not just make you feel uncomfortable, but it can also cause mold growth, which can cause health issues.

Your Energy Bills Have Gone Up

Nobody likes to open up their electricity bill and see that it costs more than usual. If you have not been using your air conditioning more than normal, but still have higher energy bills, your system may not be working properly.

Your Air Conditioner Produces Bad Smells

It is certainly not pleasant to have funny smells coming out of your air conditioner. If you're experiencing this,  then there is likely something wrong with your air conditioning system. For example, if there is a burning smell, it could indicate a problem with the fan motor or compressor. If it is a musty smell, your air conditioner may need professional cleaning.

If you notice any of these signs, you need AC repair. Call an experienced technician to diagnose the problem and fix it accordingly. Don't wait until the problem gets worse.
