You may not understand every inner workings of your air conditioner, but there are some things that you should know. For example, when you notice your AC making noises that you haven’t heard before, it could spell big trouble. It’s best to not ignore these sounds and hope they’ll fade away.
Luckily an expert AC repair company like My Guy Heating & Air is here to inform you about the range of noises your AC unit may make and what they mean. Feel safer and more aware in your home today by learning why your AC is making that noise!
Are There Normal AC Noises?
No appliances run completely silently, so be aware of your unit’s regular functioning sounds. It is common for your AC to make a sound when it starts or shuts off, but this sound should not be extremely loud or disturbing. You may also hear the sound of the air rushing through your vents, or small crinkling sounds as the vents move or expand.
AC Repair Noises
When your AC makes any sounds that are out of its normal range of noises, it nearly always needs an AC repair to make sure it returns to proper function. Be on alert for these common AC noises and what they mean for your system.
Clanking, Banging & Rattling
These noises are usually caused by a mechanical piece of your system coming loose or breaking within the unit. Your AC will not be functioning correctly with broken parts being thrown around the unit, and it’s possible for the loose pieces to cause more damage inside. It’s best to contact an HVAC professional to identify and replace the broken pieces before they cause any more damage.
Whistling & Hissing
Both of these higher pitched sounds tend to be caused by refrigerant leaks. Cracks or holes in the tubing allow the dangerous liquid to leak out and air to flow through. Since refrigerant is rather expensive as well as dangerous, we recommend turning off your unit and contacting an AC contractor sooner rather than later. No matter what, do not attempt to repair a refrigerant leak yourself.
The unusual buzz of electricity can indicate a problem with the fan, motor or any other electrical component inside your unit. Electrical work can be dangerous if not handled properly, so it’s best to call a professional.
The sound of liquid moving around could mean your drain line is cracked and allowing water to flow out. If you can inspect the drain line for damage, do so. Otherwise, a professional is your best bet.
High pitched squealing can indicate a problem with the pressure inside your unit. There are sensors that are supposed to prevent dangerously high pressure, but if your unit is broken or not working, there could be a problem. Climbing pressure can put you at risk, so call a professional quickly.
