Signs That It’s Time to Upgrade Your AC

As your HVAC system gets older, you may be thinking about investing in a replacement. While your air conditioner can last for decades, it won’t last forever. It’s better to be prepared and get ahead of a replacement than to be caught off guard when your HVAC system breaks down completely. 

If you’re considering an AC replacement in Jupiter, FL, our team can help. In the meantime, you can learn more about the signs that it’s time to start considering an HVAC replacement. If you notice any or all of the signs, it’s time to begin researching your upgrade options. 

Loud Noises

Your HVAC system is going to make some sounds as it turns on and off for heating and cooling. But you should never hear loud or surprising sounds coming from your air conditioner. If something is loud enough to catch your attention and make you wonder what it is, it’s probably a sign that something is wrong with your HVAC system. Whether the noise happens once, occasionally or all the time, you need to get it addressed. It may be an easy fix if you get it addressed immediately, but letting a problem continue on can cause more damage inside your unit. 

High Energy Bills

It’s normal for your energy expenses to fluctuate from month to month. They may be higher at certain times of the year and lower at other times. But you should never see your energy bill increase month after month without ceasing. High energy bills, or energy bills that are continuing to increase slowly over time can be caused by an older HVAC unit that is not running efficiently. 

Bad Odors

If your home has an unpleasant odor, check the air blowing out of your vents. If your HVAC system has a gas or refrigerant line, bad odors could be due to a leak. This is definitely something you want to get checked out right away. 

Bad odors aren’t just unpleasant. They can also pose health risks for your family. Breathing in gas leaks can lead to carbon monoxide poisoning. Replacing your outdated HVAC unit may actually be an investment in your health.


It’s normal to have occasional problems with your HVAC system. But if repairs are becoming more and more frequent, even if they are small, it’s a sign that your AC is near the end of its life. If you’re tired of calling our team out to make repairs, talk to us about investing in a replacement instead. Even though a new system can be costly, it comes with the peace of mind that you know it will work for years to come. Plus, you can save on your energy bills with a newer, more efficient system.
