Over time, it may be time to replace your HVAC unit. However, you may wonder whether the unit needs to be replaced, or simply need a few repairs. No need to worry, here are a few signs that signal it is time for your HVAC unit to be replaced for a newer model!

Loud Noises Coming From The HVAC Unit

An HVAC unit may make noises when starting up or shutting down, but if you notice loud noises such as extremely loud clangs, bangs, and whistling, there’s an issue. These noises may indicate a big problem with your unit, one that could be repaired if caught early, but may often signal a need for the unit to be replaced.

Repairs Cost Half Or More Of What Replacement Costs

Repairs may be the solution if they are much less costly than a replacement when it comes to your HVAC system. However, when repairs may end up taking a major hit to your wallet, costing half or more than a replacement, then completely replacing the unit is probably the best option. Paying up for a repair doesn’t mean your unit will be cleared from suffering even more troubles down the road!

There Are Uneven Temperatures Throughout Your Home

If your HVAC unit is failing to keep the same even temperature throughout your home, replacing the unit is the only solution. Usually a system that is too large for the home will cause this inconsistent bout of temperatures. If you’re freezing in your kitchen, but sweaty in your living room or bedroom, your system needs to be replaced.

Higher Energy Bills

When an HVAC system begins to deteriorate, the efficiency of the system depletes as well. If you’ve noticed your energy bills continue to climb, it may be time to replace your HVAC unit. Though regular maintenance can help with an HVAC unit’s lifespan and efficiency, an upgrade at some point is inevitable!

The System Is More Than 10 Years Old

Most HVAC systems should be replaced every 10 to 15 years, according to the Department of Energy. Even the major components of modern systems will start to deplete after 10 years. If your HVAC unit has been around for more than a decade, it will likely start to give off other signs of needing to be replaced anyway.

Poor Air Quality

An HVAC unit is the biggest factor when it comes to air quality in the summer. If your household notices mildew, mold, dust, or any unusual humidity levels while the unit is running, these may be indicators that your HVAC unit needs to be replaced.
