Top 3 Signs Your AC Needs Repair

If you notice these warning signs, then it may be time to schedule a repair for your air conditioner in order to keep the system reliable and stave off an early replacement.

  1. Your AC is making odd noises: An air conditioner won’t be silent while it operates but there are sounds that your system might make which will translate into trouble. Be on the alert for rattling, clanging, screeching, and more.
  2. The system is short cycling: When your AC system turns on and off within a few short minutes, it is known as short cycling. This can be both a sign of a repair need and a cause of other repairs, such as when your evaporator coil ices over.
  3. You notice uneven cooling: You walk through the home and notice that only some areas are cooled while others are left far too warm. Uneven cooling leads to hot and cold spots like this and indicates a problem with your AC system, which may mean it’s not cooling your whole house.

How to Know When to Replace Your AC

Maintenance and repairs can help to extend the lifespan of your AC system but it won’t make it last forever. If you notice any of these system issues, you may be better off replacing your system instead of trying to repair it again.

  • The AC is close to or over 15 years old: When your AC reaches the 15-year mark then you’ll want to start planning for a new air conditioner. At this point, the efficiency and effectiveness of the system won’t stay at the level that you need them to.
  • You need repairs too frequently: You shouldn’t need repairs more than once every few years. If you need repairs on a yearly basis or even more frequently, then your system is likely on its way to a breakdown so we’d advise getting the replacement process started.
  • Repair bills have become too pricey: Last but not least, make sure to double-check the price of your repair bill. If the warranty no longer covers a repair bill, you likely are seeing a higher repair price, to begin with. But if your bill is equal to half or more of the price of a new system then it is better to put that money toward a new air conditioner instead.

Whether you need an AC repair or a replacement, our team can help you determine the best solution. If you’re unsure, here’s when to call for AC repairs to keep your system running smoothly.

Frequently Asked Questions

Question: How long does an air conditioner typically last before needing a replacement?
Answer: Most central AC units last around 10–15 years, while well-maintained ductless mini-splits can reach up to 20 years. Regular maintenance, correct sizing, and climate conditions all affect lifespan.

Question: When is it more cost-effective to repair rather than replace an AC unit?
Answer: Repairing is usually the better option if the AC is under 10 years old, the issue is minor, the unit is still under warranty, or the repair cost is well under half the price of a new system.

Question: At what point should replacement be considered over repair?
Answer: Replacement is often best when the unit is over 10–15 years old, breaks down frequently, needs costly repairs that approach 50% of the cost of a new system, or has noticeably reduced efficiency.

Question: How do rising energy bills and poor performance factor into repair vs replacement decisions?
Answer: Consistently high energy bills or uneven cooling can indicate reduced efficiency from aging components. In such cases, upgrading to a modern system can improve comfort and lower operating costs.

Question: Are there advantages to replacing specific parts instead of the whole system?
Answer: Yes—replacing parts like the AC coil can be a cost-effective solution if the rest of the system is still in good condition, avoiding the expense of a full replacement.
