Your air conditioner is hopefully up and running reliably and effectively, considering how hot this summer season has been so far. If you are serious about cooling your home, you really need to know for certain that your air conditioner is not just running, but that it is actually running properly. If it is making strange, unfamiliar sounds, this is probably not the case. Here are some sounds to listen for in your home. SYSTEM HISSING If your outdoor unit is hissing, it may actually be drowned out by the normal operational sounds that your system is making. Should you hear hissing, remember that this could be the result of refrigerant leaking out of the system. That can cause serious operational problems, lead to inefficiency, and put your comfort in jeopardy. If you hear hissing in your home, it could be due to air leaking out of your ductwork. SYSTEM CLICKING Clicking may be the result of an electrical problem with your home cooling system. If your system is still up and running, you may be tempted to ignore some regular clicking. Because this can indicate problems like failing capacitors and faulty relays, you really cannot simply put it out of mind. SYSTEM BANGING Finally, there is the sound of banging to consider. There are a few reasons that your system may be clanging and banging, such as a bent fan blade striking a hard surface during its rotation. It could also mean that you’ve got a loose component in the system that is banging around. If you are hearing unfamiliar noises related to your HVAC unit, don’t hesitate to call us.
