Keeping Your HVAC System In Great Condition
Must-Read Explanation of Three Annoying AC Noises
Herbert Franklin
If you ever have the experience of hearing your air-conditioning system make peculiar noises, it will likely be shocking and unnerving. This is because most people are accustomed to their cooling systems running quietly. The following are three common sounds that you may hear at some point and what they might mean.
Banging
This is one of the loudest sounds you might hear. It can be caused by a bent fan blade. The force of the blade striking against the sides of an AC unit is what produces the noise. This can be corrected by replacing the bent blade. Blades can get bent during operation if they are not secured, and they can also get bent by incidents such as hailstones or rocks striking them. Consider an AC unit cover to protect your unit from damage. You might also hear banging sounds if there are loose parts in the system. For example, screws or bolts can loosen over time and cause banging sounds.
Hissing
You might hear hissing indoors or outdoors. If you only hear the hissing when you are outside near the AC unit, the sound might be caused by leaking or low coolant. Your cooling system must have adequate coolant to operate correctly. If you have a leak or low levels, you are placing your unit at risk for premature failure. Your cooling system will also perform less efficiently, and that means that you might have higher cooling costs. Allowing the coolant to completely deplete will result in your system not blowing cool air. Perhaps you will experience hissing that can be heard inside of your home. Ductwork is a probable culprit, and the hissing sound will likely be produced by air leaking through the ductwork. Faulty ductwork can cause energy-efficiency issues.
Clicking
Your AC system might naturally make some clicking noises when it turns on and off. However, abnormal clicking could be a sign of failing components such as the relays or capacitors in the system. Ignoring this type of clicking will eventually result in these parts malfunctioning, and that is why it is important to report clicking issues as soon as possible to avoid system failure. Clicking noises also occur when a cooling system has an electrical issue.
An HVAC contractor is a good resource to use to determine the exact cause of any noises that you hear coming from your air-conditioning system. If you use their preventive-maintenance services, you can reduce your chances of ever having to be worried about a noisy air-conditioning system and repairs.
