What to know before buying an AC unit replacement

When your current AC unit is showing signs of wear and tear, it’s time to start looking into replacing it. Making sure you have a reliable AC unit replacement is an important part of keeping your Phoenix home comfortable. Since this is a big-ticket item, you should also keep the following information in mind when you weigh your options:

AC Unit Replacement Size

How big an AC unit replacement do you need for your Phoenix home?

Determining the right size is important for several reasons. An AC unit that is too small won’t be able to keep your home cool and comfortable. This means you would eventually have to replace it with a bigger one or invest in a second AC unit for your home.

An AC unit that is too big means you’ll be using more energy. Units that are too large have to cycle on and off frequently. This results in more energy use and more wear and tear on these units.

The right AC unit replacement size depends on different factors, including the amount of space that needs to be cooled. An HVAC professional can help you determine this by doing a load calculation. This calculation involves information such as the direction your house faces and the type of material on your roof, among other things.

Your Budget

One of the biggest factors to consider when buying an AC unit replacement is the cost.

Before you start looking, determine what your budget is. While you estimate how much you can spend, keep regular AC maintenance in mind. Routine maintenance for your new AC unit will help ensure it stays in good condition for several years.

Energy Efficiency

Air conditioners are one of the biggest sources of energy use in Phoenix homes. You can cut down on the amount of energy your replacement unit uses by getting one that is as energy-efficient as possible. Checking the Seasonal Energy Efficiency Ratio (SEER) rating on AC units lets you know how good they are at using less energy. The higher the SEER rating, the more energy efficient the unit is.

You should look for a unit that has the Energy Star label as well. This label indicates the unit meets certain specifications for energy efficiency. While energy-efficient AC units can cost more upfront, they save you money on your energy bills over time.


Some AC units make much more noise than others. If you’re concerned about noise levels, look for an AC unit replacement that has a lower number of decibels. Decibels let you know how much noise the unit produces. Ideally, you should check for AC units that produce less than 60 decibels.
