When to Replace HVAC: Top Signs Your System Is on Its Last Legs

Having an old or worn-out HVAC system that struggles to keep your home at a good temperature can be frustrating. You might find yourself spending so much on HVAC repairs that you wonder if replacing your system would be cheaper in the long run. If you’re a homeowner wondering when to replace your HVAC system, Attyx’s HVAC experts are here to give you the information you need to make a smart decision. 

How Long Do HVAC Systems Last?

Most HVAC systems are designed to last 10 to 20 years. Each type of system has its own expected lifespan. It’s important to keep in mind that a lot of different things can influence your HVAC’s lifespan, including how much you use it and whether or not you stay on top of maintenance. 

Signs That It’s Time to Replace Your HVAC System

Even the most well-maintained HVAC system wears out eventually. Here are some important signs to watch for that can tell you when it is time to replace your HVAC system:

Breaks Frequently

If it seems like something is always wrong with your HVAC system, it might be time to replace it. Repairs can help prolong the lifespan of your system, but after a certain point, your HVAC system will require so many repairs that it becomes smarter financially to replace it.

Higher Energy Bills

If your energy usage shown on your energy bills is increasing with no clear explanation, it could be a sign that your HVAC system is struggling. Aging and broken HVAC systems lose efficiency, requiring them to use more energy to keep your home comfortable. Newer, more efficient HVAC systems are coming out all the time, so replacing your HVAC system will also give you the opportunity to choose an energy-efficient choice that will further cut down on your energy costs.

Inconsistent Temperatures

A well-functioning HVAC system should be able to maintain the temperature it’s set at in every area of the house. If your system is either struggling to maintain a temperature at all or your home has hot and cold spots, that’s a red flag that something is wrong. Some problems can be resolved through repairs. But if your HVAC continues to struggle to maintain a temperature and spread air evenly throughout your home even after service, it might be time to replace your system.

Odd Noises and Smells

If you are hearing weird grinding, squealing, or rattling noises, that’s a sign that you may have worn-out components in your HVAC system. A musty or burning smell is also a sign that something is wrong. Sometimes, this can be resolved through repairs. But if this is a consistent problem, it may be time to look into replacing your HVAC.

Excessive Dust and Moisture

If your home seems dustier than usual or you notice condensation on windows or walls, your HVAC system might not be managing airflow well. An HVAC system that is working properly should be able to maintain good air quality by filtering dust and other pollutants in the air. Healthy HVACs should also be able to control humidity levels. Changing your air filter can sometimes help cut down on dust. But when your system is old and wearing out, it may consistently struggle with air quality and humidity, leading to the need for replacement.

Age of the System

Compare the age of your unit to the expected lifespan for that HVAC system type. If your HVAC system is getting up there in age and its performance is starting to suffer, that is a sign that it is time to replace your HVAC system.
