Preparing your air conditioning unit for warmer weather will ensure your home stays comfortable. However, after not using it for the winter, this device may have damage that you don't immediately realize, preventing it from cooling the property. Recognizing when to replace this unit will help you avoid uncomfortable days during the height of summer. Here are several indications you are due for an upgrade.

When Should You Upgrade an Air Conditioner?

1. Poor Performance

When an air conditioner works efficiently, you shouldn't have to adjust the thermostat constantly to cool the home. If you do, the device is wasting energy, which you will notice as an increase on the monthly utility bills. This can occur if something is obstructing the airflow, so start by replacing the filter. If this doesn't solve the problem, you may have blockages in the ducts. If the problem persists after inspecting these areas, the air conditioner may be reaching the end of its life span.

2. Odd Noises

If your AC system is running smoothly, you should only hear a light hum when it turns on. However, if it produces grinding, squeaking, or rattling noises, there is likely a malfunctioning part. For example, grinding can occur when the compressor breaks and forces metal components together. Rattling noises suggest a part is loose and hitting metal inside the air conditioning unit. If these issues regularly return after professional repairs, replacing the unit may be a more cost-effective option.

3. Unpleasant Smells

The air that comes from the vents should not have a smell. When strange odors accompany cool air, there is likely a problem with the air conditioning unit. For example, a burning smell could indicate electrical issues that are frying the wires inside the device. Musty odors point toward mold growth, which can happen if the unit experiences damage and leaks water. Depending on the extent of the damage, it may be safer to replace the unit.

4. Moisture Issues

While a leaking unit promotes strange smells, it can also cause extensive damage to the interior components. When water corrodes the coils, they will no longer cool the air. Alternatively, the moisture may increase the humidity of the home, resulting in a warmer, thicker atmosphere. As mold grows inside the device, it can release spores inside, causing allergic reactions and respiratory issues. If you don't catch the issue early, replacing the unit may be the best option, as cleaning and repairing each damaged component can be costly.
