There are many types of repairs and maintenance tasks homeowners need to handle, including caring for the cooling system. Addressing minor HVAC repairs as soon as they occur will help keep the unit functioning for years. To catch problems early, keep an eye out for the following red flags.

How to Tell If the AC Needs to Be Fixed

1. Strange Sounds

Banging, clanging, and buzzing typically indicate a loose or broken component. Depending on the issue's severity, the technician may only need to tighten the piece or quickly replace it. However, each component is connected, so they may need to inspect and change multiple parts to remedy the noise.

2. High Utility Bill

If you haven't increased your AC usage but see a spike in the electric bill, the system is overworking itself to meet your cooling needs. This happens when the filter is full, as the unit draws more energy to push air through a clogged screen.

Duct leaks can also increase your energy bills, and they can be caused by worn materials and rodent damage. Since the ducts are located behind the walls, you'll need a professional to examine and repair the leaks properly.

3. Short Cycling

Short cycling occurs when the AC runs and quickly turns itself off, and this behavior is usually caused by a lack of refrigerant. You'll need a technician to refill the agent, as it can be toxic to handle.

Short cycling can also happen if the AC is too large for your home; oversized systems cool the immediate area quickly and will turn off soon after. Although this may not seem like a problem, short cycling wears the internal parts prematurely. Ask a professional to help you calculate how much cooling power the room needs, then replace your unit with one that's properly sized.
