The HVAC system in your home helps maintain a comfortable environment within your living space. However, systems do sometimes break down. Nevertheless, there are usually warning signs that present before an HVAC system fails. Here are a few signs that your system needs to be professionally serviced : 

Inadequate Cooling

If some of the areas within your home feel cold but others do not, there could be a problem with your system. Inconsistent cooling is often associated with dirty ducts. Blockages from dirt and debris can prevent air from flowing to certain areas of your home at the same rate that it does to other areas. If you are noticing that some rooms are much cooler than others, contact an HVAC specialist like River City Heating & Cooling in your area to have your ducts cleaned and your system assessed.

Dust Accumulations

As you dust your home regularly, you may notice an increase in the amount of dust on your furniture even if you have not changed your dusting schedule. This could indicate an issue with your HVAC system. The air filters of your system may need to be changed. In addition, there could be a breach in your ductwork that is allowing the entrance of foreign debris from areas outside your home.

Loud Sounds

Most HVAC systems are not completely silent. It is not unusual to hear a low hum as your system is in operation. However, loud sounds, such as banging noises, clanking or knocking, may suggest a problem. Sometimes, unusual sounds are associated with loose system components. In some cases, a portion of your system may even have become fully disassembled. Operating a system whose structure is compromised can necessitate additional repairs.

Unresponsive System

If you set your thermostat to a new temperature and your HVAC system does not respond by cooling or heating your home appropriately, there is likely a problem. You may need a new thermostat. However, an unresponsive system could also indicate a wiring problem, a failing sensor or an unlit pilot. In addition, there could be an issue with the compressor of your system.

As your HVAC system ages, it is more likely to experience problems. If you notice signs that your HVAC system is not operating properly, it is best to have it inspected by a trained professional. He or she will be able to advise you of the type of repairs that may be needed. In some cases, a replacement unit may be necessary
