One of the tell-tale signs that your residential air conditioner needs to be serviced is that the unit is not producing cool air. Unfortunately, by then, your home is warm and you may be uncomfortable. Fortunately though, your unit will often give you signs that something is wrong before it gets to this point. Here are three common signs that your air conditioning unit may be in need of repairs. 

Your Air Conditioning Unit is Providing Spotty Coverage

One of the signs that your air conditioning unit may need to be serviced soon is an air conditioner that is providing spotty coverage. For example, your kitchen may be cool and your bedroom may be warm. In some cases, this may be a sign of duct work problems, while in other cases, it may be caused by your air conditioning unit failing to produce enough cold air to cool your home sufficiently. Either way, you should have your unit inspected by a professional HVAC contractor. 

Your Air Conditioning Unit is Loud or Noisy

Another sign that your air conditioning unit may need to be serviced soon is a loud or noisy air conditioning unit. You know what your air conditioning unit sounds like when it is cycling and cooling off your home. If it suddenly starts to sound louder, or if you hear any strange or unusual noises, such as clanking, squealing or grinding, you need to have your unit looked at. Strange noises can be caused by loose screws, worn belts and hoses or parts that are reaching the end of their lifespan. 

Your Utility Bills Are Increasing

The final sign that your air conditioning unit may need to be serviced is an increase on your utility bill. When you run your air conditioning unit, you expect your energy bill to increase. However, if the increase is dramatic, it may be because there is a problem with your air conditioning unit that is causing it to use more energy. This may be caused by a dirty air filter, dirty evaporator coils or low refrigerant levels. Contact a professional to determine why your air conditioning unit is using so much power and how the problem can be repaired so your unit is efficient again. 

If you notice any of these three signs, your air conditioning unit is trying to tell you that it needs to be serviced. Contact a company like Ongaro And Sons to schedule an appointment to have your unit inspected and repaired. This can help it to produce cool air all summer long.
