What To Know
- If you notice that the airflow from your vents is weak or nonexistent, it could be a sign that your air handler is not working properly.

When your HVAC system acts up, it’s natural to wonder if you can replace just the air handler. After all, it’s the part of the system that circulates the air, so it’s easy to assume that it’s the culprit. However, the answer isn‘t always straightforward.
What Is an Air Handler?
An air handler is a component of a central air conditioning or heating system. It consists of a blower, a coil, and a filter. The blower circulates the air through the system, while the coil absorbs or releases heat. The filter removes contaminants from the air.
Signs of a Faulty Air Handler
- Reduced airflow: If you notice that the airflow from your vents is weak or nonexistent, it could be a sign that your air handler is not working properly.
- Increased noise: A noisy air handler can indicate a problem with the blower or the motor.
- High energy bills: If your energy bills have been increasing without any obvious reason, it could be a sign that your air handler is not operating efficiently.
- Uneven temperatures: If you notice that some rooms in your home are warmer or cooler than others, it could be a sign that your air handler is not distributing the air evenly.
- Frequent repairs: If you find yourself having to repair your air handler frequently, it may be time to replace it.
When to Replace Just the Air Handler
In some cases, it is possible to replace just the air handler. This is usually the case when:
- The air handler is old and inefficient.
- The air handler is damaged beyond repair.

When to Replace the Entire System
However, in other cases, it may be necessary to replace the entire HVAC system. This is usually the case when:
