Signs You Need To Replace Your Air Conditioning

Some air conditioner problems may be obvious, but it can be hard to tell if the unit has reached the end of its service life. The professionals at A+ Derr are well-versed in recognizing the difference between an AC unit needing repair and one requiring replacement. Some indications that it’s time to replace your air conditioner include:

  • Spiked or consistently high power bills
  • Unit is 10 to 15 years old
  • No cool air produced
  • The unit fails to power on

Making the Most of Your AC Replacement

Choosing to install a new air conditioner is a big decision, and getting it right means more than just picking a brand you’ve heard of. The right system, properly installed, will deliver dependable comfort, better energy efficiency, and cleaner indoor air for years to come. In Evansville, Louisville, and across Kentuckiana, summer heat and humidity can put any AC system to the test, which is why a quality installation matters as much as the equipment itself.

Working with an experienced team ensures every detail is handled—from sizing your system for your home’s layout to making sure the installation meets manufacturer standards. This helps your new AC run efficiently from day one, lowering energy costs and reducing strain on the unit. It also means fewer unexpected breakdowns and a longer overall lifespan.

Regular maintenance after installation keeps your system performing at its best and protects your investment. Annual tune-ups can identify small issues before they turn into costly repairs, while keeping your home consistently cool and comfortable through the hottest days of summer. With decades of service in the community, A+ Derr provides the knowledge, skill, and local experience needed to make your AC replacement a smooth process from start to finish.

AC Replacement FAQs

On average, modern air conditioning systems last 10 to 15 years. Regular maintenance conducted by qualified professionals can maximize this potential.

Multiple factors can figure into the decision to replace an AC unit. If repair costs approach 50% of a replacement, that’s often an indicator that replacement is a good decision. The timing of a replacement, like around the time of the home’s sale, may also impact whether replacing is the best decision. Since cases like that are often unique, it depends on the situation.

It’s best to have a new AC unit installed before the summer hits to ensure you and your home are set up for success. This way, you won’t have to go without cool air when the temperatures are the highest.

A surefire way to select the best AC unit for your home is with the help of an expert. We will consider things like the size of your home and how much energy you wish to use to determine the best option.
