One key component of your air conditioning unit is the control board, sometimes referred to as the “brains” of the system. If it’s not working properly, neither will your air conditioner. HVAC.com breaks down what an AC control board is, signs you may need a new one, and answers the question – how much does AC control board replacement cost?

What Is an AC Control Board?

The AC control board, also referred to as a circuit board, is typically found mounted on a panel in the furnace compartment or inside the indoor air handler. The control board acts as the command center of your cooling system, responsible for managing the operation of the fan, compressor, and other key components, ensuring they function in harmony to cool your home effectively.

Signs Your AC Control Board May Need Replacement

As a homeowner, it’s important to recognize the signs that your AC circuit board may be failing. Common indicators include:

  • Inconsistent Cooling: If your air conditioner isn’t cooling your home evenly, it could be due to the control board not properly regulating the components.
  • AC Won’t Turn On or Off: A malfunctioning control board can prevent the air conditioner from starting or stopping, leaving your home either too hot or too cold.
  • Frequent Cycling: If your unit is turning on and off too frequently, it might be due to a control board issue.
  • Error Codes: Modern air conditioning units often display error codes when there’s a problem with the control board. If you see an unfamiliar code, it’s worth investigating or contacting an HVAC contractor.

How Much Does AC Control Board Replacement Cost?

The cost to replace an AC control board can vary widely. On average, homeowners can expect to pay between $400 and $600 for an HVAC professional to replace a control board. Here’s a closer look at what influences the cost:

Type of AC Unit

The make and model of your air conditioner can significantly affect AC circuit board replacement cost. High-end or complex systems may require more expensive control boards.

Labor Costs

The cost of labor varies by region and the HVAC professional you hire. In general, labor costs depend on the complexity of the job and the technician’s experience.

Warranty Status

If your air conditioner is still under warranty, you may only need to pay for labor, which can significantly reduce your out-of-pocket expense.

Availability of Parts

If your AC unit is older or the control board is difficult to find, the part itself may be more expensive.

Tips to Save Money on AC Control Board Replacement Costs

Replacing an AC control board can be costly, but there are ways to manage and reduce the expense:

  • Check Your Warranty: If your AC is under warranty, the control board may be covered, meaning you’ll only need to pay for labor. Always check your warranty before proceeding with repairs.
  • Get Multiple Quotes: Don’t settle for the first quote you receive. Contact several HVAC companies to compare prices and find the best deal.
  • Consider Preventative Maintenance: Regular AC maintenance can help prevent control board issues in the first place. This can save you money by avoiding costly emergency repairs.
  • Ask About Payment Options: Some HVAC companies offer financing that allows you to spread out the cost of repairs over time. This can make a significant expense more manageable.

DIY vs. Professional AC Control Board Replacement

Some homeowners might be tempted to tackle the replacement themselves, especially since the control board itself typically costs between $100-$300 dollars. However, DIY repairs are not recommended when dealing with this important AC component.

Replacing an AC control board involves dealing with complex electrical components, and mistakes can lead to further damage or even injury. Hiring an experienced HVAC professional ensures the job is done correctly and safely. 

Professional installation often comes with a warranty on the work, providing peace of mind. Plus, if your manufacturer’s warranty is covering the cost of a new control board, installation by an HVAC dealer may be required to uphold the warranty terms so your unit continues to be covered.
