How Old Is Too Old? When to Replace Your AC

Outdated Air conditioning Unit

Let’s face it—it’s never easy to part with your current air conditioner. A new system is no small investment. Plus, you want to be sure replacement is necessary. 

If you’ve kept up with seasonal maintenance, your AC equipment should last 10 to 15 years. However, some factors can wear your AC out prematurely. Inconsistent upkeep or leaky, dirty ducts can overwork your equipment. 

If you think it’s time for a new unit, no need to fret. Air conditioners have become much more efficient since the last time you purchased one. Switching to a new model can cut your cooling costs by up to 50 percent, according to the US Department of Energy (DOE)

Need an expert assessment? Let a Chesterfield Service professional perform an energy audit on your current heating and cooling system. We’ll give you the numbers so you can make an informed decision for your Missouri home. 

From our team, here are some red flags that might mean your AC is ready to retire: 

  • Your utility bills are higher than usual. 

Did this month’s electrical bill make you gasp? Odd upticks in energy costs can be caused by a failing air conditioner. As internal components like the blower or evaporator coils begin to fail, they use more electricity. 

  • You need to schedule repairs frequently. 

Has your HVAC technician become a regular guest at your Chesterfield home? Multiple back-to-back repairs are never a good sign. If intermittent repairs end up costing you more than a replacement, in the long run, a new cooling system is the best way to go. 

  • The cooling feels “spotty.” 

An old compromised AC system will sometimes produce “hot spots.” This can also point to other factors like leaky ducts or a minor ventilation problem. However, if your system is more than 10 years old, or displays other symptoms, it may be time for a change. 

  • Your home feels more humid than usual. 

A properly functioning AC unit balances the humidity in your home by removing water from the air. As the evaporator ages, it may lose some of this ability. If left unchecked, you can run into issues like poor air quality or mold growth. 

If one or more of these issues applies, have a professional check it out. It’s also a good idea to read up about your specific make and model. Cheaper units tend to have shorter lifespans and are prone to more problems. 

When selecting a new model, be sure to read up about its SEER (Seasonal Energy Efficiency Ratio) rating and compare it to your current unit. The higher the SEER, the more efficient it is. Many high-efficiency SEER units are eligible for tax rebates. That’s another reason why making the switch might be more affordable than you think.
