Signs It's Time to Replace Your Air Conditioner

Andrew Knatcal • July 11, 2024

As summer heat waves roll in, your air conditioner becomes one of the most cherished appliances in your home. But nothing lasts forever – not even your trusty AC unit. So, how do you know when it's time to say goodbye to your old air conditioner and welcome a new one? 


Here are some straightforward signs that it might be time to invest in a new cooling system.

Your Air Conditioner Is Old

Most air conditioners have a lifespan of about 10 to 15 years. If yours is pushing or has surpassed this age range, it might be time to start shopping. Older units are not only less efficient but are more prone to breakdowns and repairs.


Frequent Repairs

If you find yourself frequently calling the repair technician, it might be more economical to replace your unit rather than fork out money for diminishing returns. Constant repairs are a clear indication that your AC is struggling to keep up with your cooling needs.


Rising Energy Bills

Notice a steady increase in your energy bills during the summer months? It could be a sign that your AC unit is losing its efficiency. Newer models are significantly more energy-efficient and could help reduce your monthly bills considerably.


Inconsistent Temperatures and Poor Performance

Does your AC leave some rooms too hot while others are too cold? Or does it seem like it’s working overtime but can’t quite cool your home effectively? Inconsistent cooling is a telltale sign that your unit may be on its last legs or improperly sized for your home.


Refrigerant Issues

If your air conditioner uses R22 refrigerant, also known as Freon, you should consider replacing it. R22 is harmful to the environment, and as of 2020, it is no longer being produced in or imported into the U.S. New AC units use more environmentally friendly refrigerants that are less harmful to the ozone layer.


Strange Noises or Unpleasant Smells

Banging, grinding, or squealing noises are not typical for a healthy AC system. These sounds could indicate that something inside the unit is broken or about to break. Similarly, musty smells might suggest mold inside the unit or ductwork, while a burning odor could signal an electrical problem. Both are serious issues that need immediate attention and might warrant a full replacement.


Excessive Dust or Humidity

An increase in dust or humidity inside your home can be a sign of problems with your AC unit’s ability to filter and dehumidify the air. If you notice a change in your home’s air quality, it could be due to an aging AC system failing to regulate humidity or keep dust at bay.


Considerations for Replacement

When considering replacing your air conditioner, think about not just the immediate cost, but also the long-term savings. Newer models are more energy-efficient, quieter, and offer better air quality. They also come with warranties that can give you peace of mind for years to come.


On a Final Note:


Recognizing when to replace your air conditioner can save you money, reduce stress, and keep your home comfortable during the hot summer months. If your AC unit is showing any of these signs, it might be time to consider an upgrade. Not only will you enjoy cooler air and lower energy bills, but you’ll also have a reliable system when you need it most. Don't wait for your old AC to break down completely; being proactive about replacement can ensure you stay cool all summer long. Call us at 32 Degrees for new
