You may need a new air conditioner if it’s not working properly. While you may not be prepared to replace it, having a unit break down on a hot day is inconvenient. You might also wait longer for a busy HVAC contractor and pay higher service fees. It’s often less expensive upfront to repair a unit, but let’s look at the average air conditioner lifespan and the most common signs that an AC needs to be replaced.
How Long Do Air Conditioners Last?
An AC unit can last 15 to 20 years. That’s assuming it’s been maintained properly. Routine care, as simple as changing the filters when recommended, can increase an air conditioner’s lifespan. Annual tune-ups, which include lubricating moving parts, cleaning the system, and performing minor repairs, also help.
However, there are other factors in play. An AC unit may fail sooner if it’s used more frequently. This means a unit in a warmer climate may not last as long as one in a milder location. In the U.S., homeowners in the South generally must replace their ACs more often than those who live in the Northeast. Also, exposure to salty sea air can shorten the life of the outdoor unit.
Top Signs It’s Time to Replace Your AC Unit
Have you had your air conditioner for more than a decade? You’re probably not ready to part ways with it, whether the unit has sentimental value or you’re not prepared for the investment. To help make the decision easier, here are the more common signs that AC replacement should be a consideration:
Your AC Is Over 10 Years Old
Air conditioners have a finite lifespan. Over time, regular use leads to wear and tear. Maintenance can counteract or slow down the effects, but the system won’t last forever. If your AC system is over 10 years old:
- It will operate less reliably and efficiently.
- Replacement parts become harder and more expensive to find.
- You could benefit from a newer, more energy-efficient model.
Energy Bills Keep Rising
Your aging air conditioner might be using more electricity than you think. Mechanical or electrical problems can cause it to run longer or otherwise use more energy to maintain the desired temperature. Your utility bills will continue to increase the longer you wait, straining your household budget. However, replacing an AC unit can lower your energy bills.
The AC Runs Constantly But Cannot Keep Up
If your AC unit is always running, but your home never gets cool enough, it may have a serious issue. A damaged coil, refrigerant leak, or faulty blower motor can cause it to run constantly. Other possible causes include electrical problems or a system that was sized too small for your home. Consider replacing an AC that suddenly starts running without stopping. It’s using too much energy and will break down before too long.
Your AC Still Uses R-22 Refrigerant
Does it still use R-22? If considering when to replace an AC unit, this is a good reason to get a new one. An R-22 phase-out was completed in 2020 after a decades-long effort by the U.S. Environmental Protection Agency (EPA).
To check the type of refrigerant your AC uses, look for a label or plate on the compressor or evaporator unit. It may also be listed in the system’s manual. You can ask your local HVAC contractor as well.
Refrigerant is just one thing to think about. In California, new systems must also meet various other HVAC regulations, so research these when planning your purchase.
Uneven Cooling or Poor Airflow
As your air conditioner’s performance declines with age, parts of your home may not get cool enough. This could be due to an airflow issue in your ductwork. But if your AC is 10+ years old, temperatures vary from room to room, and air flow from vents is weak, call Fleetwell to have a technician inspect the system.
Uneven cooling and poor airflow can be due to a failing compressor. The compressor usually lasts the life of the system, so if it’s going bad, replace the AC unit inside your home as well. Otherwise, you risk having a mismatched system that runs inefficiently and doesn’t last as long.
Frequent Repairs
Frequent repairs are one of the most common signs your AC needs to be replaced. A one-off repair may be worth the cost if your air conditioner is in good health overall. However, if the system has recurring problems, continuing to pay to fix it can be more expensive than buying a new one to start with. You can also compare the cost of repairs vs. replacement—if a repair estimate exceeds 50% of the price of a new AC, consider replacing it.
Unusual Noises
A loud noise is a clear indication that you may need to replace an AC unit. Banging, screeching, rattling, squealing, grinding, scraping, and other abnormal and irritating sounds indicate problems with components inside the system. The cause can be anything from a loose belt to a failing motor. At the very least, the unit must be repaired, but if it’s older and has other issues, consult with our HVAC technicians about replacing it.
