Your HVAC keeps your home comfortable throughout the year. While most systems last up to 15 years, old age, lack of maintenance, or improper installation could lead to a shortened life span. There are many ways to determine your need for air conditioning repair, and one of the most common signs is by hearing strange noises.

Is your AC making these sounds? If so, it may be time to call for a repair:

• Hissing: If your unit sounds like a snake, you might require air conditioning repair. Hissing is a common sign of a leak within the refrigerant line. This allows outside air into the system and conditioned air to escape. The hissing noise comes from a constant stream of air that is being released from the pipe.

• Bubbling: A bubbling noise is similar to that of a hissing one. It often originates from the same issue. When your cooling system has a leak, air bubbles are more likely to form within the refrigerant line. As they rise and pop, you may be able to hear the activity. When you hear bubbles in your HVAC, turn off your system and call for air conditioning repair immediately.

• Grinding: A harsh noise, grinding can indicate an issue with the system's air handler. The air handler in your central air is made up of a motor and a fan. Both of these are well lubricated to avoid high levels of friction. However, over time, this lubrication wears down. If this happens, you will be able to hear it as the air handler grinds against itself.
