Watch Out For These Signs

No one wants to think about replacing something like their AC system, but the truth is that nothing lasts forever. Eventually, as time passes, your unit may not be repairable and need replacement. But how do you know when that time comes? In this blog, learn key signs to help you realize it may be time to replace your AC system.

Your AC System is Older Than 10 Years

If your AC system is over ten years old, it's time to upgrade. While newer models are more energy efficient, they also have many other benefits. Newer AC models are equipped with features that can help you better manage your home's temperature. Smart thermostats, for example, can learn your preferences and adjust accordingly.


Additionally, many new AC systems come with built-in air purifiers, which can improve your home's air quality. A new AC system will run more efficiently than an older model, helping you save money on your energy bills. So if your AC system is starting to show its age, it's time to consider investing in a new one. You'll be glad you did.

The AC Unit is Making Strange Noises

If your AC unit is making strange noises, it could indicate something is wrong. Rattling or hissing noises may mean something loose inside the unit, while a humming noise could tell that the bearings are worn out. If you hear a screeching noise, it could signify that the fan belt needs to be replaced. In any case, it's crucial to have a professional look at your AC unit as soon as possible to prevent further damage.

Dust and Dirt Are Coming Out of the Vents

If you notice dust and dirt coming out of your vents, there are a few possible explanations. First, it could be that the air filter needs to be replaced. A clogged air filter forces the system to work harder and lead to dirty vents.


Another possibility is that the ductwork itself is dirty. Over time, dust and debris can build up inside the ducts, causing them to blow out into the room when the system is turned on. If this is the case, you'll need to have the ducts cleaned by a professional.


Finally, there's also possibly an issue with the HVAC unit itself. If the coils or other components are dirty, they may not be able to circulate air effectively, leading to dusty vents. Whatever the cause, it's important to address the problem as soon as possible to ensure that your home remains comfortable and clean.

Your Energy Bills Are Getting Higher

If you've noticed that your energy bills have been steadily creeping up, there could be several reasons why. One possibility is that your AC unit is getting old and isn't as efficient as it used to be. Even a slight decrease in efficiency can result in higher energy bills, so it's worth checking to see if your AC unit is due for an upgrade. You could also contact your utility company for more information.

Your Unit Just Doesn't Keep You Cool

Maybe you've noticed your energy bills going up despite not changing your habits. Or perhaps you've struggled to keep your unit cool, no matter how much you adjust the thermostat. If so, your AC unit may no longer be as effective as it once was. Over time, units can become less efficient due to wear and tear. In addition, changing weather patterns can also impact a unit's performance. If your unit isn't keeping you cool like it used to, it's time to call in a professional. They can help diagnose the problem and recommend the best action. With their help, you can keep your home comfortable all summer long.
