Steve’s Heating & Air Outlines Why Your Central Air Conditioner is Making Loud Noises

AC Making Hissing Sound: One of the sounds that definitely means trouble for you is hissing. Of course you can ensure that there isn’t a slithering culprit hiding by first. The real problem is if the unit is hissing that is a sign that there is a leak in the line. You will hear it outside at the main component unit. This is where the lines are that is using the refrigerant to actually cool the air that is being sent in your house. The refrigerant line is important to have sealed so that the right amount of charge in in the unit. If there is not enough charge the unit will not be able to cool the house down. The hissing can be a break in the actual line or damage to the connection. You want to make sure that this is looked at and repaired right away. It may require the unit being charged back up again.
Grinding Sounds from AC: When you are listening for a sound that is bad grinding is one of them to be concerned about. The unit has a motor that works with bearings to help circulate the air. The circulation is needed to make sure that the air is being propelled through the house. The grinding means that the bearing have most likely worn down and there is friction being created. If left unchecked it can lead to more damage. You want to make sure that you have a technician look at it right away.
AC Starting & Stopping Too Often: Another problem that people have with their unit is when it is starting and stopping fast and often. This is called short cycling and is a sign that the unit is the wrong size or the filter is clogged and needs to be changed out. The short cycling is a major problem and can end up causing your unit to wear out fast. It also will cost you more on your energy bill that you will notice. You want to make sure that you call out a technician to look at the unit and diagnose what the issue may be.
