Signs an Air Conditioner is Failing

Air conditioning systems often make noises, especially when starting up.

During the hot summer, a house should be a haven from the heat, so the air conditioning system must be in strong working order. However, air conditioning systems are susceptible to problems like any other machine. Homeowners should be aware of the signs of a failing air conditioning unit to resolve the problem and maintain cold air in the home.

Insufficient airflow

The output of the HVAC system is measured in cubic feet per minute (CFM). It’s a unit that measures the volume of air pumped into the home. One way to gauge the cooling system's airflow is to place a hand over a register. If the system is not putting out adequate CFM, there should be a noticeable difference in the amount of air coming out of the register.

Unusual noises

Air conditioning systems often make noises, especially when starting up. These noises, however, aren’t always innocent. If unusual noises come from the air conditioner, it’s best to call a professional. These noises clearly indicate that something isn’t working as it should.

Warm air

Air conditioners are meant to provide cool air, so if the unit blows warm air, something is awry. The cooling system pulls in air from outside, mixes it with warm air from the home, and runs it over a condenser, which cools it. When the air pumped into the house is warm, a professional must be contacted to assess the problem.

Bad smell or odor

Every system has a smell when it’s used for the first time. In the fall, the heating system may have a slight burning smell, and the air conditioner may have an old water smell in spring. This is normal as the system circulates for the first time. If it happens regularly or lasts longer than a few minutes, it is likely a warning sign that something is wrong in the system’s operation.

Age of the system

The average useful life of an air conditioner ranges between 10 and 15 years. Regular maintenance, like changing filters every three to six months, and having the system regularly cleaned and maintained, like ductwork, can help the unit reach the 15-year mark. As an air conditioner ages, it is likely to face more frequent breakdowns and repetitive issues. It’s important to start considering replacement as the unit approaches ten years of age.

If an AC system shows warning signs, contact a professional for assistance. These experts can resolve various issues to ensure the house remains a refuge from hot summer air.
