Signs You Should Replace Your A/C Unit

Knowing when it’s time to replace your air conditioner can be difficult, as HVAC problems are not always easy to diagnose. In general, there are a few key signs that it’s time to call a professional and replace your unit:

  • It simply doesn’t run anymore. Likely the most obvious (and most annoying) sign of them all, if your A/C system is having issues starting or staying running, this is a red flag that you need a new unit. Phoenix is known for its brutal summer heat—being without air conditioning in the summertime is an issue that requires immediate attention.
  • Foul smells or strange sounds from your unit. Do your vents smell? Does it seem like moisture is building up and creating mold? Or do you hear a distinct grinding, rubbing, or squealing? Any of these can mean it’s time to replace your air conditioning system. Foul smells could indicate mold growth, which needs to be addressed immediately by a professional before it does more damage to your home. Additionally, unusual or loud sounds indicate there is an issue with the mechanics of your A/C unit, which means it is not working as efficiently as it should and may break down completely.
  • The air isn’t as cold as it used to be. If warm air is blowing from your vents in the middle of summer, that is a sure sign your A/C unit is on the way out. Warm air can be a sign of coolant leaks or other mechanical failures. These need to be inspected immediately by a professional to avoid further problems, such as moisture build-up.
  • It’s more than 15 years old. A/C units, unfortunately, age more like yogurt than fine wine. It is recommended that you change your air conditioning system between 10 and 12 years—anything older than 15 years is a breakdown waiting to happen. Not only are old A/C units more likely to break down and need repairs, but the older technology simply isn’t as efficient. Newer air conditioners generally run more quietly, are more energy efficient, and are simply more practical for the modern home.

Should I Repair or Replace My A/C Unit?

You may opt to repair your air conditioner rather than have an entirely new system installed, and if the problem is minor enough, it may be the most cost-effective solution. Here is a quick way to determine if you should repair or replace you air conditioning system. 

In general, you should repair your A/C unit if:

  • It is under 10 years old or still considered “new.”
  • You haven’t had many new or recurring issues with it yet.
  • An HVAC professional recommends repairing over replacing after inspecting it.

However, you may want to consider replacing your A/C unit if:

  • It is over 10 years old.
  • It still uses R-22 Freon refrigerant, which the government is trying to phase out.
  • This isn’t the first major breakdown, or if issues are frequent.
  • You have noticed a distinct spike in energy usage.
  • The unit is running continuously or not blowing out cold air anymore.

Choosing to repair or replace your air condition system can be difficult. To make an educated decision, it’s best to call a professional HVAC contractor that can do a thorough inspection of your unit. Not only will ACE Home Services come out and inspect your air conditioner, but we will give you insightful recommendations on whether to repair or replace your unit. We handle the entire installation process from start to finish and make sure your house stays as cool as it should be.
