3 Simple Signs Your AC System Needs Repair

Posted on

From keeping you and your family comfortable during the various seasons to maintaining a healthy and safe amount of moisture in the home, it is easy to see the importance of your heating and cooling system. While it is used a great deal, you may not be giving your heating and air enough attention. Without ongoing maintenance, the system may struggle or stop conditioning the air inside your home. If you are noticing the following signs, your air conditioning is most likely in need of repair.

High Energy Costs

Half of your home's total energy usage stems from heating and cooling.  Your energy costs may be higher in the summer and winter, due to extreme temperatures and need to run the air conditioning and heat more frequently, but abnormally high bills may stem from an underlying issue.

Compare your energy usage to the energy usage at the same time the year before. If your bill is higher or you know you are needing to run your system longer and harder to condition the air, consult a technician.

Damaged ductwork may be causing conditioned air to escape, increasing the amount of energy needed to move air into the home. Even the smallest holes in the ductwork can account of an enormous amount of wasted air, so it is important to repair this damage immediately to condition your home in an effective, efficient manner.

High Humidity Levels

Your home's air conditioning cools your home, but it also removes moisture during the cooling process. If your home's unit is not sized correctly, it will run long enough to remove the heat and cool the house, but not long enough to remove moisture from the home. Known as short-cycling, this problem can increase humidity levels in your home.

High amounts of humidity are unpleasant, but the moisture can also damage your home. You may notice peeling paint, warped wood, and even condensation on your windows and doors. High humidity can also lead to the growth of mold. Mold is unappealing, but it is also dangerous. In severe cases, mold can interfere with your breathing.

The physical signs of humidity are easy to see in the home, but you can also use a hygrometer to measure the moisture in the air. Place the tool in front of a few vents inside the home and take measurements. Also, measure the air in various rooms of the house to determine if you have humidity issues.

Oversized units will need to be replaced or you can install a central dehumidifier in the home to remove the humidity.

Strange Noises

Your outdoor units will make noise while they are conditioning your home. However, certain noises may be a warning sign of distress. Here are a few noises that may signal your system needs repair or replacement:

  • Banging – A loud banging coming from inside your outdoor unit will most likely stem from the blower assembly. A part of the blower motor may have become loose over time. In addition, a large piece of debris may have become trapped inside the unit. Be sure to disconnect the power to the unit before inspecting for signs of damage or debris.
  • Squealing – If you are healing a squealing noise from your outdoor unit, there is an issue with the compressor. Bearings may be excessively worn, causing them to rub against surrounding parts while the system is running. In most cases, you will need to replace the compressor.

Your heating and cooling system is a necessary part of your home, so understanding the signs your system is in distress is beneficial. Use this guide and the help of a HVAC technician from a place like A-1 American Services to diagnose and repair issues affect your home's heating and cooling.
