What Are The Signs I Need A New Air Conditioner Unit?

May 11, 2022

Deciding to replace your air conditioner can be a big decision. A new air conditioner can be costly, but you’ll need to decide whether to repair the one you have or get a new one. There are some signs that your air conditioner may be on its last legs. 

How Can I Tell My Air Conditioner Unit Needs To Be Replaced?


You can expect most air conditioners to last anywhere from 10 to 15 years. Factors like routine maintenance and climate can add or take away from your unit’s lifespan. Newer units are more energy-efficient, and you won’t be dealing with frequent breakdowns and repairs. 

Awkward Noises

Some noises can be expected with an air conditioner, but some can indicate a more severe problem. Any type of grinding, squealing, or scraping are usually signs of essential parts like the compressor, blower, or condenser coil starting to fail. Also, low refrigerant levels can make a lot of noise, too. 

Skyrocketing Electric Bills

Have you noticed a steep climb in your energy bill? An older unit could be the culprit. Many older models have to work a lot harder to cool your home, and you’ll notice a jump in your bill. A newer unit is an easy way to save money, and it’s better for the environment.

Low Airflow

If it takes a long time to cool your house to the set temperature, it could be time for a replacement. Anytime you stand next to a vent, you should feel a strong blast of air coming through. Weakened airflow is typically a sign of a failing compressor. Other causes could be a blockage or an issue with your air ducts. You should always hire a professional to get a correct diagnosis. However, replacing the entire unit is usually more cost-effective than replacing the compressor. 

Frequent Breakdowns

If you constantly call an HVAC company to repair your unit, it could be time for a new one. Older parts will begin to fail, and it can seem like you never have an air conditioner that functions. 

Horrible Smells

You should only smell neutral air with an air conditioner working properly. Bad smells can mean that mold or mildew is starting to form, and burning smells signify your unit is about to go. You should get the advice of a professional right away to prevent any dangerous breakdowns. 

As your air conditioner starts to get older, pay attention to the signs of a failing unit. Stay proactive, and always consult the help of a professional if you are not sure.
