4 Signs You Need a New HVAC System

Nobody wants to endure the scorching subtropical climate of Bradenton, Florida, without a reliable air conditioning system. Even those who relish the Florida sun appreciate the comfort of cold air conditioning when they’re ready to retreat indoors. However, your HVAC system won’t last forever, and eventually, it’s time for a replacement. Here are some signs that indicate it’s time to upgrade your HVAC system.

You Need Constant Repairs

One of the most noticeable signs that you need a new HVAC system is that it needs constant repairs. HVAC systems are designed to last about a decade with minimal repairs. So, needing multiple repairs each year could mean that your system has worn out.

This is even more likely if core system parts like the coils have been damaged more than once and need to be replaced. These parts should last the entire lifespan of the AC system unless something unusual happens.

However, this does not apply to disposable parts. Parts like startup capacitors, filters, and drain hoses are based more on their maintenance and quality. Having these parts replaced is common and doesn’t indicate that there is something wrong with your HVAC system.

Loud Noises From Your HVAC System

The most familiar sound you should expect from your HVAC system is the soft hum of air circulating through the vents. However, should you detect any other unusual noises—particularly loud banging, grinding, or hissing—it's an indication that something may be wrong with your system.

Banging sounds suggest that there's movement occurring within, pointing to the possibility that a component has become loose. Likewise, grinding noises are not typical, as the parts are intended to function smoothly together. This may indicate that small components within the motor are deteriorating, making it essential to have a professional evaluate the situation promptly.

Hissing is a problem as well since it means that air is entering or leaving the system at a high speed when it should not. This could likely be a coolant leak somewhere. However, a professional technician will need to check this soon since a coolant leak can damage your system if it is left unresolved.

Outdated HVAC System

There will come a time when it is more cost-effective to replace your HVAC system than it is to keep repairing it. Plus, systems that are more than 10 years old are significantly less energy-efficient than the current models. If a system repair will cost more than 40% of a new installation, or your energy bill is noticeably higher than it was a few years ago, it may be time to replace your HVAC system.

A new system could save you a lot on your energy bill since newer systems are more efficient. You will also experience improved comfort with a new more effective HVAC system.

Longer Running Times

You might notice that your system kicks on more often and is staying on longer to get your home to your desired temperature. This could happen because of bad coils or maybe a failing blower motor. A professional can check these parts to see if that’s the only issue.



But if the coils and motor are fine, then it’s likely a more serious issue that’s overworking your system.

When your AC has to keep running for a longer time, that means it’s having trouble producing and circulating enough cooled air around your house to keep it at the set temperature. A significantly less energy-efficient unit is one that needs replacing.

To determine if a simple repair is needed or it’s time to upgrade to a new system a professional will have to make an assessment and recommendation to you.
