How Long Do Air Conditioners Last?

When cared for, air conditioning units can last a long time. Typically, room air conditioners last 10-15 years before they need replacement. Window, wall, and portable units are the most popular room ACs. They are easy to install, and there are a wide variety of sizes available. Central AC, PTAC, and Ductless Mini Split Systems tend to last longer, but they are more expensive and require professional installation. The life span varies based on wear and tear as well as the type of cooling system.

Most people end up replacing their old AC units before they break down. The most compelling reason for you to replace your air conditioner is energy efficiency. Energy bills run high in the summertime, and old ac units use more electricity resulting in higher cooling bills. Many local utility companies offer incentives for you to recycle old energy-hogging appliances, including air conditioners. According to the Energy Star website:

If all room air conditioners sold in the United States were ENERGY STAR certified, the cost savings would grow to over $350 million each year, preventing more than 6 billion pounds of greenhouse gas emissions annually - equivalent to the emissions from over 570,000 vehicles.


Replacing old appliances with newer and more efficient models is a great way to save money over time. If you're looking to find ways to reduce your environmental impact, replacing old appliances that lose efficiency with newer efficient ones is one approach that will reduce power consumption. You will also enjoy the exciting new features and performance of today's most energy-efficient appliances.

Tips to Care For Your Air Conditioner

Keep It Working Its Best


It's essential to clean your AC regularly. Regular cleaning will keep your air conditioner running for a long time. Always reference the use and care manual for your exact air conditioning model for best cleaning product recommendations. If you install your air conditioner every season, make sure you clean out any buildup of leaves, dirt, pollen, or dust from the coils before having it installed in your window or wall sleeve.

Most ACs have a removable filter designed to filter impurities from the air. Running an AC with a dirty filter screen can reduce the AC unit's energy efficiency and, in some extreme cases, could spread dust, germs, bacteria, and even mold through the air. It's a simple task to check and clean most AC filters.

For room AC units, the filter should be easy to find. It's usually an easy pull-out on the side or front of the unit. With some models, you might need to remove the AC's front face to access the filter. You can also vacuum the filter housing with a thin vacuum nozzle for best results before inserting a newly cleaned filter.

To clean either window, wall, or central AC filters, run the filter screen under running water. If needed, you can use liquid soap and a soft-bristle brush to clear away any sticky debris. Always reference the use and care guide before using any cleaning agent on your appliance. After cleaning, let your filter dry completely before replacing it.

Before You Buy

Air Conditioners are kind of picky. AC power is measured in British Thermal Units (BTUs) per hour. The higher the BTUs, the more powerful the cooling system. Room air conditioners are fussy– if you oversize an AC, the room will feel clammy and damp. If you undersize an AC, the unit will work too hard and eventually burn itself out.

To find the right size AC unit for your room, consider the room size, average occupancy, natural light, and heat sources like a nearby stove. From there you will also need to consider the physical size of the unit, as well as the plug type. It can get complicated, which is why we recommend reaching out to an AjMadison expert. You can also use the BTU calculator on our website, a super helpful tool to help find the right AC for your space.

AC units are not a one-size-fits-all solution, so finding the right product to cool your space is crucial. At AjMadison, you can find the widest selection of air conditioners for rooms of all shapes and sizes and a team of experts to help you find the best AC to keep you cool all season long.
