5 Signs You Need To Replace Your AC

It’s easy to feel like your air conditioner is a permanent part of your home, especially when it’s working perfectly. Like all appliances, though, AC units will need to be replaced eventually. But how do you know when it’s time for AC replacement?

We here at Air Tech of Pasadena have the answers you need to make an educated decision about your HVAC system. You can trust our team to recommend the best solution to your cooling problems and complete a flawless AC installation that keeps your home comfortable and efficient. Here are five signs it’s time for you to install a new AC in your home:


If your air conditioner is over 10 years old, it’s heading towards the end of its lifespan. Most central air conditioner units last 10-15 years, but you should start paying close attention to them at 10 so you aren’t blindsided by deterioration. While nothing is certain, AC units that have received regular maintenance and had fewer repairs throughout their lives will last closer to 15 years. That’s why it’s so important to schedule HVAC maintenance!

Inadequate Cooling

If your AC just doesn’t work the way it used to, it may be time to replace it. We’re not saying you should replace your AC at the first sign of a problem, but an air conditioner that can’t keep up anymore does need to be replaced. Over time, you may notice that your air conditioner no longer meets your cooling needs due to wear and tear — once this happens, it’s time to start looking for a replacement.

High Energy Bills

Part of the air conditioner aging process is decreased energy efficiency. Just like not being able to provide adequate cooling, low energy efficiency occurs due to wear and tear over time. The system is simply not meant to last forever!

If your energy bills have steadily increased over time to a point that you’re paying much more than is normal for air conditioning, it’s a sign that your AC is at the end of its life. Don’t mistake a steady rise for a sudden jump, though. A sudden significant increase in your utility bill is more likely to indicate the need for AC repair.

Frequent Repairs

Does it seem like your air conditioner is constantly breaking down and requiring expensive repairs? It may actually be more cost-effective to replace the unit with one that won’t break down for years. If you’re unsure whether to repair or replace your old AC, consider whether you’ll spend more money continuing to repair it for the next couple of years than the cost of a new unit. You may be surprised to find that AC installation is the cheaper option!

Humidity Issues

Moisture removal is a natural part of the air conditioning process, so most homeowners don’t experience humidity problems inside. In the Pasadena area, this is incredibly important! If you’re dealing with humidity build-up in your home, it could be that your old AC isn’t functioning properly. Make sure to call an HVAC professional if you’re having humidity issues so they can pinpoint the problem and recommend the best course of action.
