Most homeowners often struggle in learning when is the right time to replace their HVAC systems.

Most of them even entirely forget about it until they work fine.

However, suppose you are one of those who have experienced getting stuck inside your freezing home with a broken HVAC system.

In that case, you will definitely know how important it is to have a functioning cooling or heating system. 

Therefore, here are five important indicators pointing out that your HVAC system needs a replacement and should not be ignored. 

Five Indicators That It’s Time For A New HVAC System

Your HVAC System Has Aged To Over Ten Years Old.

If you have not changed your HVAC system in ten years, then the chances are it is still utilizing Freon (R-22) gas, whose manufacturing has already been banned across the globe.

Therefore, it is now time to replace your cooling agent with a safer and environment-friendly one.

So, if your HVAC system is over ten years old, now is the time for a replacement. 

The HVAC System Is Only Blowing Warm Air And Not Cold.

When the temperature rises, you want to turn on your HVAC system for some cold breeze.

The HVAC system in your house has only one purpose: to keep your home comfortable by cooling in the summer and heating in the winter.

So, if your HVAC system is blowing out warm air in hot weather instead of cold, there could be an issue with its compressor or the refrigerant.

Though the latter does not always need a replacement because it depends on your HVAC system’s age.

If it is much older, the repair cost will be higher than the replacement cost. 

Your HVAC System Has Poor Or Weaker Airflow.

If you turn on your HVAC system after a long time and notice that the vents are barely blowing any cool air, the system might have a problem.

The most common reason is clogged air filters that need to be replaced regularly.

However, if that is not the reason, then the lack of airflow indicates a severe problem, such as a broken motor, damaged blower fan, leakage, etc.

So, if your HVAC system is not working correctly, you might notice an increase in your energy bills unless you decide to replace it with a new one. 

The System Is Producing An Unusual Odor Or Is Louder Than Usual.

If you notice foul odors or your HVAC system suddenly turning louder than usual, there might be a severe problem with the system.

For example, the system might have a loose nut or bolt if you hear a rattling or buzzing sound.

However, if the noise is loud, thudding, grating, whistling, or grinding, the system might require immediate attention.

Furthermore, if your system produces strange musty smells, you should call a professional duct system cleaner to check for mold and mildew inside the vents.

Your HVAC System Runs All The Time Or Doesn’t At All.

While it is customary to keep turning your HVAC system on and off to make your home comfortable, it is not at all okay for the system to short-cycle.

It means that the HVAC system is turned off before it completes its cycle.

Also, keeping your system on for a long time can cause it to deteriorate, along with increased utility bills.

Therefore, it is important to keep a regular check on your cooling system for minor wear and tear and repair it before your system breaks out entirely. 

Final Thoughts.

While it is natural to feel overwhelmed and stressed because replacing an HVAC system requires a lot of effort and money, there are good reasons to do so if you want your HVAC system to work efficiently in the long run.

In addition to making you live without an HVAC system at all, replacing it on time will also save your energy costs and repair bills down the line.
