5 Signs That Indicate the End of an Air Conditioners Life Span

Couple using table fan because their AC unit is broken because of expended Air Conditioners Life Span

Coming home to a warm and toasty house only sounds great during a cold winter. When you get home after a long day during the middle of summer, and it is 90 degrees outside, the last thing you want to deal with is a hot and humid house.

Your A/C Unit is an integral part of your home. If something goes wrong, it can lead to unwanted discomfort for everyone in your household.

Here are 5 signs you might need to upgrade your air conditioner:

1. Your AC has hit the 10-year mark

Did you know that all air conditioners have an AC life expectancy? On average, you can expect a regular AC to have a life span of 10 years, and a higher-end model is around 12-15 years.

If your AC is not working like it once did, it is time to check the unit age. If your A/C Unit is over 10 years old, it may be a sign you should retire it for good.

2.   The indoor humidity is out of control

Did you know your air conditioner also helps with indoor humidity? The warm air moves over the coils in your A/C Unit and leaves a portion of the water behind.

This water drips off the coils and exits the system through the condensate drain. If this process is disrupted or malfunctioning, it may feel like the current outdoor temperature, or worse, a big sauna.

Every climate provides different challenges, and sometimes the problem isn’t a maintenance issue with your AC.

If you just bought your A/C Unit, your system may be too small for your home, you are not running it as often as you should, or you need a whole-house dehumidifier. These help balance the temperature in your home and keep the moisture down.

3. High energy bills

If your electricity bill seems to be climbing every month or year, it could be a problem with your AC unit or other electric appliances. Yes, things get more expensive every year. Unfortunately, HVAC systems are the largest expense on your energy bill.

The good news is that trading in your old AC unit for a newer model can help you save on your monthly electricity bill. Modern A/C Units are more energy efficient than older models and can help you cut down on monthly costs. If your air conditioner is 10 years or older, you may save up to 20%-40% on your monthly energy costs by making the switch.

4. The breakdowns are becoming more frequent

You can only have your go-to HVAC professional come to your house for AC repairs so many times before it becomes a problem. If your AC keeps breaking or is not working the way you want it to, it probably means it is wearing out, and it is time to get a new one. The longer you wait, the more the repair costs continue to increase.

Common air conditioner problems include:

Keep in mind that frequent visits from an HVAC pro can be the result of a faulty installation or inadequate AC maintenance over time. Improper installations can lead to poor airflow, leaky ducts, and energy inefficiency.

If something doesn’t feel right, get a second opinion. To increase the longevity of your air conditioner’s life, make sure you find someone you trust to get the job done right!

5.   It’s blowing out warm air during the summer months

One of the most obvious signs you need an AC is if you feel like your AC isn’t doing its job. If an AC is broken or not performing as well as it once was. Test it like this:

  • Walk over to your air conditioning unit and see if it’s pumping out warm air.
  • Check your thermostat to ensure it was not flipped on accident.
    • If it is not, it is possible that your cooling system is failing or needs to be replaced because of a faulty condenser or other related problems.

Our advice? Don’t wait until it’s too late. The summer weather can be harsh, especially if you don’t have a trusted A/C Unit by your side. The best part is that upgrading your air conditioner doesn’t need to break the bank. When you find the perfect modern model, it can also help you save on your energy bill and repair bills.

Oh my god what an amazing company! I literally called one hour ago and said that my thermostat wasn’t working and there was a knock on my door within the hour! They told us what to do to fix it therefore saving us a $600 bill. They came right away, none of that we can see you in 48 hour junk. Amazing.

They were able to provide me with same day service, friendly and very responsive. Also, I got 2 other quotes and the pricing was the most competitive.
So thankful and impressed! My dad returned home after having open heart surgery to a completely dead HVAC system in the middle of summer. Definitely not ideal. The repair was going to be pricey so he opted for a new unit. A crew came out on a Saturday and did a very clean and efficient install. Highly recommend this company!!!

Very professional, work very neat and cleaned up and removed stuff. Very impressed with all of the staff and the company.
Our AC decided to quit during one of the hottest heatwaves in years. We called Scott's and someone was at the house to give us a quote in 30 min. From the moment they answered our first phone call through the install everyone was amazing, professional and provided a quality product and excellent service. Craig, Jose, Dexter were awesome! One of the new guys brought us a portable unit at 9:30 PM on a Friday so we could sleep. We missed his name, but shout out to him as well (he likes to give high fives). Thanks Scott and team for everything. We highly recommend!!!

For the past week I've worked with Craig on getting estimates for a new A/C unit, and he has been great at answering my questions and addressing any concerns. Very responsive and knowledgeable, straight shooter and direct! I didn't have to deal with any up-selling like working with a used car salesman (I experienced that with other bigger local A/C companies providing quotes). For these qualities alone I would recommend Scott's A/C, even though I will disclose that we ultimately went with another quote from a family referral of an A/C company. Had that family referral not been apart of our consideration, we would definitely choose and recommend Scott's for new A/C installs and service!
Dan in sales, outstanding jobgoing over equipment and helping us make what was the best decisions for us on purchasing new a/cinstall, plus scheduling the next day!Boris and Justin were excellent with communications while install and after! very clean, professional taking old out and installing new!ty
We can't thank Scott's enough. We came home to a air conditioner barely limping along. I called Scott's first thing in the morning and they had a technician out that day. Unfortunately our system could not be saved. The salesman Craig came out that day as well and quoted a new system. Since it was a Friday we could not get the system installed until Tuesday. Scott's provided us with a portable system which definitely helped during the grueling heat wave in Central Florida. Tuesday came, the installers showed up on time and did an awesome installation job. Cleaned everything up and went on their way. Everyone was pleasant, professional and great to work with! Thank You Scott's Heating & Cooling!

Always happy with their response time. Issue started last night causing our A/C unit to shut down. Made a call to Scott's Heating and Air in the morning and a tech was here by 10:45am. Tyrie, the tech, is awesome. He quickly took care of the problem and had us up and running in no time at all. He is knowledgeable and professional and did a great job.
Perfect company to do business with. Professional and courteous in all phases of project.

Excellent response and service. After 25 years of being serviced by a competitor I decided to change companies. AC was out and in need of replacement. Within 24 hours we had the sales rep here and new unit going in for a reasonable expense. No upselling, phony money savings, or timeshare presentations- just a new system without being targeted and pressured into pricey newer technology that will also become obsolete and non reparable every system cycle. I’m recommending to everyone looking for a new provider
