Phoenix AC Replacement Guide

If you are on the fence between Phoenix ac replacement or just a repair, we know it can be a hard decision to make. But if you are facing another scorching Phoenix, AZ summer, spring is a great time to make the decision so you can get ahead of Murphy’s Law and avoid an unfortunate air conditioner breakdown on the hottest day of the year.

Questions to ask:

  • Should I have a whole new AC system installed in my home? 
  • Or, should I keep up with the continual maintenance of my existing air conditioning system?
  • Will I save money if I get a new energy-efficient air condition system?


At AZ Perfect Comfort, we specialize in air conditioning and heating systems, and we get these questions all the time. Our Phoenix-area customers rely on the expertise of our team of certified AC installation technicians to give them all the information they need to make an informed decision.

So, we’re sharing everything you need to know about AC replacement in Phoenix, AZ, including how long you can expect your air conditioner to last, how to know when it is time to take the plunge and replace your air conditioning system, the best air conditioners for Arizona, and more.

How long should an air conditioner last in Arizona?

Although the national average lifespan for an air conditioner is about 15-20 years, we don’t have to tell you that here in Phoenix, AZ, our ACs get put through a lot more than many other parts of the country. 10-15 years is pretty typical, but when your air conditioner approaches the 7-year mark, you may wish to seriously consider a replacement.

Why so soon? Your old AC could be costing you 20-40% more in energy costs than if you replaced it with a newer, energy-efficient AC. Plus, by this time–especially in Arizona–it’s likely that your AC’s maintenance needs are starting to increase. From a cost and time perspective, you just might be better off replacing it.

Of course, there are many factors that play into how long your AC system lasts including:

1. How often you maintain your AC

Scheduling regular maintenance on your heating and cooling systems will keep minor issues from turning into major ones.

2. The size of your AC unit

ACs that are too large are constantly turning on and off, while air conditioners that are too small are running all the time. Both put excessive stress on your AC, increasing the likelihood of repairs and maintenance

3. Your Temperature

When the mercury soars above 110 and you keep your home at 75, you are tasking your AC with cooling it by 35 degrees. Dropping your thermostat even lower than that puts extra pressure, causing your air conditioner to work even harder.

When is it time to replace my air conditioner?

There are certain signs to look for that may tell you an AC replacement is going to be your best bet. They include:

1. Your air conditioning system is 7-10 years old

You could be literally throwing money out the window if your AC is old and inefficient. Plus, an air conditioner that doesn’t run efficiently probably isn’t cooling effectively, either. While you weigh the pros and cons of AC replacement and repair, go check the age of your unit. It might help you decide more quickly.

2. You’re constantly repairing it

At some point, your air conditioner is just going to wear out. And if you are limping it along by constantly maintaining it, it just might be time to replace it. Consider how often and how expensive your AC maintenance repair bills have been over the last few years to help you make the decision.

3. Your home isn’t cooling properly

The whole reason you have an AC is so your home can be cool and comfortable at all times. Not just some of the time and not just in certain rooms. If it’s not doing its job, it’s time to seriously consider replacing it.

4. You have humidity in your home

Moisture in the home can add up to big problems. And quickly. If you are battling humidity in your home, it means your AC isn’t working properly. When an air conditioner is doing its job, it’s pulling the heat and moisture out of the air in your home and replacing it with cool, dry air. Humidity can be a sign of a poorly functioning AC or leaky ductwork.

5. Your AC is noisy

A loud air conditioner is more than a nuisance, it’s a sign of problems with your AC. Depending on the noise it’s making, which can range from banging and clanging to squeaking and squealing, even screeching and screaming– yes, screaming–you could have any number of things going on. Causes of a noisy AC could include loose belts, an out-of-balance part, loose debris in the unit, or a refrigerant leak (this is the one that causes a high-pitched screaming sound).
