Regular maintenance will usually keep your air conditioning running smoothly. However, it is essential to be aware of signs that may indicate problems between visits from a HVAC professional. By paying attention to the following three issues, you can address minor problems before they require significant repairs.

1. Warm Air

If you notice that warm air is blowing from the vents of your AC, you should check the thermostat first. Ensure that its settings have not been interfered with and have been set correctly. If the system still blows warm air after the check, the problem could be a faulty thermostat, a refrigerant leak, or a clogged air filter.

2. High Humidity

During the summer, the weather outside can be unbearable. However, that does not mean the air inside should be poor quality. One of the advantages of an air conditioner is that it can regulate humidity inside your home. Your home’s ideal humidity levels should be between 30% and 50%. Higher humidity levels may cause problems with the quality of air and can increase mold growth. Some signs of high humidity in your home include foggy windows, surface condensation, and a mildew smell. This could be caused by a malfunctioning compressor or an issue with the refrigerant levels in your cooling system.

3. Bizarre Noises

Some air conditioners can make low-level noises during start-up and shutdown. However, loud and unusual noises can indicate problems with your system. Rattling, grinding, and buzzing noises can indicate that a component in your system has become loose. If the problem is ignored, it can lead to a total system failure. Alternatively, if your air conditioner emits grinding or screeching noises, it could indicate a problem with the fan motor, belt, or bearings. These components may require lubrication or replacement to prevent further damage.
