If your outdoor air conditioning unit is in need of replacement, you may be wondering if you also need to replace the indoor unit. The answer isn’t always simple and depends on what type of system you have and the age or condition of your indoor unit. Let’s take a closer look at when replacing both units might be necessary.

Matching Systems

When it comes to replacing your outdoor unit, there are two primary types of AC systems that can be installed—single-stage and multi-stage. Single-stage systems typically have only one speed, while multi-stage systems have multiple speeds, allowing them to better adjust their cooling output based on the current temperature outside. It is important to note that these two types of systems must match. If you are replacing an old single-stage system with a new multi-stage system, then you will also need to replace the indoor unit as well. The same goes for switching from a multi-stage system to a single-stage system; both units must match in order for them to work properly.

Age & Condition of Your Indoor Unit

In addition to matching systems, the age and condition of your indoor unit are factors that should be taken into consideration when deciding whether or not to replace it along with the outdoor unit. Generally speaking, if your indoor unit is more than 10 years old and/or showing signs of disrepair such as leaking refrigerant or damaged ductwork, then it may be time for an upgrade regardless of whether or not you’re replacing the outdoor unit. On the other hand, if your indoor unit is fairly new (less than 7 years old) and in good working condition, then you likely don’t need to replace it unless it doesn’t match the newly installed outdoor unit as mentioned above.

Replacing an outdoor air conditioning unit can seem like a daunting task but with this guide, you can rest assured knowing that deciding whether or not also replace your indoor air conditioning unit is much easier than it seems! To make sure everything runs smoothly during installation, it is best practice to consult with an HVAC professional who can assess your current setup and advise on any necessary changes prior to replacement. That way, you know that everything will be running properly once installation has been completed!
