Signs You Need Air Conditioning Replacement

If your AC is approaching the end of its service life, you should plan for a replacement before it fails completely. Otherwise, you risk being without a working air conditioner when you desperately need one.

These are common signs that it’s time to schedule an AC replacement:

  • Your AC needs frequent or expensive repairs.
  • Your energy bills have risen significantly and continue to climb.
  • Your system isn’t properly sized for your home.
  • Your air conditioner is over 12 years old.
  • Your system isn’t keeping up with your needs.

If you’re unsure whether your air conditioner is ready to be replaced, our team can help. We’ll assess your system and determine if a replacement is needed or if repairs are a better investment.

AC Replacement FAQs


When you replace an aging air conditioner with a modern, energy-efficient system, you can expect more effective cooling, lower energy costs, lower repair and maintenance needs, and improved comfort.

Typically, an AC replacement takes one to two days, but each home and system is different. Our team can give you a more specific time frame based on your system’s size, type, and location within your home.

A seasonal energy efficiency ratio, or SEER, rating measures an air conditioner’s overall efficiency. Systems with a higher SEER rating are more efficient and effective at cooling your home, which means you should have lower monthly cooling costs.

The company scheduler was very helpful and got us a same day appointment. Matt, the technician was very prompt and professional and even provided advice on the issue. The price was reasonable even though the technician traveled from Maryland to our home in Martinsburg WV. I would recommend Larry and Sons for plumbing repairs to anyone.
