When Should Homeowners Replace Their Air Conditioner at Home?

Installing an air conditioning unit helps in maintaining better air quality at home. As a result, people experience fewer health conditions connected to breathing, like asthma and colds. However, a study suggests that an air conditioner’s life expectancy is only 10 to 20 years from installation, and it’s best to have them replaced starting on the 10th. But which common signs indicate an air conditioning unit is ready for replacement? Here are some ideas.

1. Rising Electricity Bills

If you’re noticing a higher number of monthly electricity bills, it’s a sign that your air conditioner is reaching the end of its lifespan. Resetting your air conditioner’s thermostat can help reduce electricity usage costs. But if it’s a matter of replacing your air conditioner, it’s best to have it done as soon as possible.

2. Producing Unusual Sounds

A good air conditioner makes very little noise. But if you notice that it’s producing unusual sounds that can last for a few hours, it’s best to have it checked immediately. But if the sound continues even after the needed repairs, then replacing the unit itself might be the only solution.

A noisy air conditioner means that it needs repair or replacement. Unusual sounds, like a loud humming noise or a rattling sound that are not normal, may indicate that there are loose parts in your air conditioner. Fixing these parts will require a trained technician to have your unit opened up.

3. Continuous Leaks

Leaking from your air conditioner means that it needs immediate replacement. The reason for the leaks can be due to cooling coils getting corroded or a blocked condensate line. Sometimes, an air conditioner can leak due to a cracked or split outer wall and water pressure that gets built up inside the unit. Either way, a cold air conditioner leaking water will also mean an accumulation of rust inside.

However, if it’s leaking a clear liquid, it means that refrigerant leaked out of the air conditioning system. If you notice any of these signs and have an air conditioning unit in your home, you should check it immediately. If it’s already time to replace your unit, then you can hire a professional contractor to help you out.

4. Exposed Wires

Exposed wires are significant indicators that it’s time to replace an air conditioning unit. They may cause electrocution and fire hazards when exposed to liquids within the AC unit. Therefore, it’s best to have the unit checked by a professional or have it replaced immediately to avoid more costs or for the safety of the people living in the house.

5. Weak Air Flow

Weak airflow indicates that your air conditioner will soon need replacement. However, there are instances where blockages inhibit air conditioners from performing their best. Therefore, it’s better to get it checked first before deciding if it’s time to replace the entire unit. Check out if your air conditioning system is producing an even, cold airflow. If it’s not passing through the whole home, you might want to replace it with a new system.


If you’re out looking for signs that it’s time to replace your air conditioning unit, these are just some of the everyday things you will see. However, if you’re in doubt, it’s always good to ask for the opinion of a certified technician. They can conduct a series of tests to check for the air conditioning unit’s health, calibrate it as necessary, and provide a comprehensive diagnosis of the condition and the needed solutions to bring the unit back to its usual performance.
