When your AC is functioning as it should, you don't need to sweat the summer months. No matter how high the mercury soars outside, you know the temperature inside your home will always be just right.

However, with summer on the way, it's important to consider how well your AC is prepared to handle the heat. When the air inside your home is too warm, it isn't just uncomfortable—it can impact your overall quality of life. Research shows that the temperature of the air around you can have a significant impact on how much and how well you sleep. Hot temperatures make it harder for the body to shed heat and cool itself, reducing the quantity and quality of sleep.

There's also an element of distraction when your AC isn't performing efficiently. An AC that's loud or runs constantly doesn't just cost you money on your energy bills—it can rattle your concentration and distract you from your day. For individuals who frequently work from home, this can be especially frustrating.

Having an AC that functions efficiently season after season makes a difference in your health, comfort and happiness. Watch for these common signs and symptoms that your AC isn't performing efficiently anymore.

1. Your Energy Bills are Unusually High

If your energy bills have suddenly skyrocketed, your AC might not be working properly anymore. When an AC is older and starts becoming less energy efficient, it will run longer and work harder to cool your home. The harder it works, the more electricity it uses, which causes electric bills to soar. 

2. You Don't Have a Consistent Temperature Throughout Your Home

Ideally, your AC cools your home evenly every time. When you experience inconsistent temperatures in your home, it's a sign of an inefficient system and one that might be at the end of its lifespan. 

3. Your AC Unit Runs Constantly

It's normal for air conditioners to run in cycles of about 15 minutes approximately two to three times per hour. If your AC is running more often during the summer, there's a good chance it's not performing as efficiently as it should.

4. Your AC is Over 10 Years Old

Just like anything else, as your AC unit ages, it starts to lose its efficiency. Components start to get older and not work as well, which results in your AC using more energy to cool your home. If your AC has been around a decade or longer, it's likely not performing as well as it once did. Before the summer's first heat wave, consider whether you should repair or replace your AC. 

5. You Need Frequent AC Repairs

Another sure sign that your AC is no longer efficient is when you find yourself constantly scheduling repairs. Whether you notice a strange sound or an unpleasant smell, these are issues that must be addressed by a professional. If you're simply patching problems with your AC, it may be time to invest in a new system. Talk to your local Lennox^® dealer to help make an informed decision.
