Should I Replace My Air Conditioner?

over 3,000 reviews

It’s easy to take your air conditioner for granted and delay planning for a replacement air conditioning system until it breaks down completely or until it requires an expensive repair. Even with yearly maintenance, AC systems gradually lose efficiency over the years, which can make replacement a way to save money on energy use and repair bills.

How Long will My Air Conditioner Last?

There are signs homeowners can identify before their AC system breaks down completely. If you are seeing any of the following, it is time to start shopping and planning for your new AC system.

1. If Your System is More than 10 Years Old You Should Consider AC Replacement

  • Air conditioners wear out just like any other household appliance. A well-maintained AC system, one that has received annual maintenance, will last 10 to 15 years, according to the National Association of Home Builders.
  • Yearly professional tune-ups help your air conditioning system last longer and keep manufacturer warranties valid in case of unexpected equipment failure. However, systems that have not been professionally maintained annually over their lifespan may not even last the full 10 years. Yearly tune-ups by Steve’s professional AC technicians keep your system in good working order, prevent costly repairs, and increase AC system lifespan. Hawai’i Energy offers rebates for AC tune-ups performed by Clean Energy Allies like Steve’s Plumbing & AC that help a great deal with the cost.

2. If Your Electricity Bills are Rising, It May Be Time to Replace Your Air Conditioner

  • Even the best-maintained AC systems gradually lose efficiency over the years. If your air conditioning system is getting older, consider whether your high electricity bills could be the result of a faulty, failing, or inefficient AC system. An air conditioner that is working inefficiently will run more frequently and use up more electricity while still not adequately cooling your house.
  • Many utility companies provide comparison charts of how your bill has changed month over month and year over year and can help you assess the reason for energy usage increases. Hawai’i Energy has rebates available for new central air conditioning systems and new mini-split ductless air conditioning systems.
  • Newer cooling systems are more energy-efficient, cool better, and run quieter than older systems. Investing in an energy-efficient AC system will lower your electricity bills and provide you with more comfort.

3. If Your AC System uses a Phased-Out Refrigerant such as R-22 it is Time to Consider Replacement

  • On January 1, 2020, the manufacturing of ozone-depleting refrigerant R-22 was discontinued. Homeowners can have Steve’s qualified AC technicians inspect their system to determine what kind of refrigerant it uses. If your air conditioner was installed before 2010 it probably uses R-22. If your AC system uses ozone-depleting refrigerant and it needs repairs, the cost of repairs or adding refrigerant can be cost-prohibitive.

4. If Your Air Conditioning System has Repeated Breakdowns you Should Consider Replacement

  • Whether your AC system has reached the end of its average lifespan or not, having multiple repair jobs in a row could indicate it is near wearing out. If you have already fixed one issue and more are popping up, it might be best to cut your losses and replace your system.
  • Older air conditioners have more aesthetic issues as well. Rust is a problem, along with being noisier than newer models.

What if I Cannot Afford to Replace my Air Conditioner Right Now?

Replacing your central air conditioner or your mini-split ductless AC system is more affordable than you think. New AC system installation comes with an immediate monthly energy cost savings that you will enjoy on your electricity bill. New AC units outperform old units by 30% to 50% according to Hawaii Energy, no matter the Energy Star rating.

Many manufacturers offer attractive financing options for new air conditioning systems. And to encourage AC replacement with energy-efficient models, Hawai’i Energy offers immediate rebates of up to $750 per system. Steve’s air conditioning experts are happy to help you find financing options and will help you obtain your rebate from Hawai’i Energy as well.

If you have any plumbing needs this is the company to use. They said they would be there at 9:30 and by gosh, they showed up at 9:28 that not a normal thing when it comes to plumbing. Both of them were not they answered all my questions without hesitation and got the job done within 45 minutes even though they said it would take an hour and a half.

Brayden and Maka worked on a major repair at our home over a time period of four days. We have high praise for both of them, their professionalism, courtesy, friendliness, and reliability. Steve’s Plumbing is lucky to have these two fine employees.


Shon Bolo was very courteous. He was very informative about how Plumbing is just as important as the engine of a car. He was very respectful. Even though I wasn’t able to get everything done as expected. Shon was able to install my laundry tub to get my washer ready to drain and connected. Definitely would recommend shon bolo to friends and neighbors. Thank you very much for the wonderful job. Great service Shon!!
