The Top Signs It's Time to Replace Your AC Unit

In Memphis and the surrounding areas, where summer heat and humidity can be intense, a working air conditioning system isn’t just about comfort—it’s essential for daily life. At AirMasters Air Conditioning & Heating, we’ve helped local homeowners stay cool since 1996. We know the signs when an AC unit is on its last legs and are here to help you determine when it’s time to consider a replacement.

Here are the top signs you might need professional AC replacement.

1. Your AC Is Over 10–15 Years Old

Most air conditioning units have a lifespan of around 10 to 15 years, depending on usage and maintenance. If your system is approaching or beyond this age range, it may be costing you more in energy and repairs than it's worth. Newer models offer significantly improved energy efficiency, which means lower utility bills and better performance.

2. Frequent Repairs Are Adding Up

An occasional repair is normal, but if you find yourself calling in a technician every season—or worse, multiple times in a single summer—it may be time to replace the unit entirely. Those repair bills can quickly add up, and you could end up spending more on a failing system than you would on a new, efficient unit.

3. Your Energy Bills Keep Climbing

Have your electric bills been creeping up, even though your usage hasn’t changed? Older or struggling systems tend to work harder to cool your home, which drives up your energy costs. A new, energy-efficient AC system installed by our team can help bring those bills back down.

4. Uneven Cooling or Weak Airflow

If some rooms in your home feel much warmer than others or if the airflow coming from your vents seems weak, your AC unit might be failing. These issues can result from aging components or ductwork issues. A professional inspection can determine whether a repair is possible—or if it’s time for a full system upgrade.

5. Strange Noises or Odors

Odd sounds like grinding, squealing, or banging could indicate serious internal problems, such as worn-out motors or loose components. Similarly, musty or burning smells are red flags that shouldn’t be ignored. These are often signs that replacement is the safer, smarter route.

6. Your Home Feels Humid

One of your AC unit’s main functions is to remove humidity from the air. If your system is no longer keeping humidity levels in check, it’s not doing its job effectively—and it could mean internal failure is near.
