4 Things to Consider Before Replacing Your AC Compressor

One of the most common problems that occur in air conditioners is an ill-performing compressor. It is the AC system’s power unit, which circulates the refrigerant and is responsible for keeping your unit cool. That is why having a damaged or completely broken compressor can significantly affect the performance of your AC unit.

Some of the obvious signs of a bad compressor include loud noises coming from the unit, water leaks around it, and reduced airflow. To fix the problem, some choose to replace the compressor, while some prefer to replace the entire unit.

If you think you have a damaged AC compressor, here are four things you first need to consider when deciding whether to replace the compressor alone or the entire unit:

1. AC Compressor Replacement Cost

The first thing most homeowners consider is the replacement cost of a new AC compressor or unit. The price of this will depend on the type of air conditioner you use, its size, and its compressor speed.

For instance, a compressor can cost up to $2500, and a new unit can cost $3500 to $5500, depending on its type. Regardless, both the AC compressor and unit typically come with a warranty for one year and ten years, respectively.

2. Unit’s Active Warranty

When you buy an air conditioner, it often has two related warranties: the unit warranty and labour warranty. If its 10-year unit warranty is still active, you may consider contacting the manufacturer to use it and save costs. In terms of the labour warranty, it is mostly available for relatively new units and if your contractor is still active.

3. Age of AC Unit

Another thing that you should consider is the age of your air conditioner unit. According to manufacturers, it typically has a 10- to 15-year life span. If the compressor is within or nearing its maximum age and suddenly breaks down, the damage is probably irreparable, and it would be best to replace the entire AC unit.

4. Performance of the current unit

Lastly, you should consider the performance of your current AC unit. Several factors affect the quality of performance of an air conditioner, including its age, usage, and maintenance. Typically, an old unit has low-quality performance and is less energy-efficient. If you want to have a better performing unit that will save you a lot of energy costs in the long run, you should consider replacing your old unit for a new one.


Having a bad AC compressor can affect the performance of your entire unit. To address the problem, you need to replace its compressor or the entire air conditioner unit. When deciding which action to make, you should consider several factors.

First, you should consider whether you can afford the replacement costs of either of the two and decide which one is more cost-effective. You should also consider its warranty, age, and performance, especially if you want to save on costs.

Generally, you only need to replace its compressor if it still has its warranty, and you purchased the unit a few years back. On the other hand, you may consider replacing the entire unit if it is near its expected life span and performs poorly.
