Every homeowner should know when it’s time to replace their HVAC system. Outdated HVAC systems are notorious for being incredibly inefficient and requiring expensive maintenance and repairs.

Avoid all the hassle by knowing when it’s time to get your unit replaced and learn more about why replacing your system can be the best thing for your home.

1. Older than 10 Years

If your HVAC system is older than 10 years, then it’s time to replace it. Even if you can keep your system running with some maintenance and repairs, it’s not worth the trouble. Here’s why.

Older HVAC systems are less efficient. What does that mean for you? It means you spend more money on energy bills, your home isn’t heated or cooled evenly, and there might even be hidden dangers you aren’t aware of.

2.  Your System Makes Noise

All HVAC systems make a little noise; it’s normal. But, if your system begins hissing, ticking, buzzing, rattling, or screeching, then it’s most likely time to think about replacing your unit.


Hissing may indicate a leak. If you hear hissing, turn off your system immediately and call a licensed technician. Refrigerant leaks can be hazardous and are known for causing carbon monoxide poisoning.

3.  Frequent Repairs and Expenses

If you find yourself spending half the cost of your system just in repairs, then it’s time to replace your HVAC system. Making repairs on an outdated system always costs more because parts are harder to come by, and they typically need more extensive work.

Don’t overspend in repair bills and maintenance. The point of an HVAC system is to make you comfortable in your home and big repair bills are enough to make anyone uncomfortable. Updating your HVAC system is a wise investment for all homeowners.

4. Uneven Heating and/or Cooling

You might have noticed that some areas of your home are hotter or colder than others. This can be a big sign it’s time to replace your HVAC system, especially if your system is older than 10 years. 

Your HVAC system may be on its last leg. Uneven heating and cooling could indicate malfunctioning zone controls, leaking ductwork, or an outdated system. Replacing your HVAC system should solve this problem, making your home a lot more comfortable.

5. You Want to Increase Your Home’s Resale Value

Did you know replacing your HVAC system is a great way to increase your home’s resale value? Not only will it increase your home’s value, but replacing your HVAC system can also help you avoid damages and the need for frequent repairs.

Outdated systems can cause property damage. After years of heating and cooling, the expansion and contraction caused by changing temperatures could lead to loose electrical connections, leaking ducts, and water damage.
