How Much Does It Cost to Install a Dedicated Circuit for a Window or Through-the-Wall AC Unit in Florida? (2026)

Installing a dedicated circuit for a window or through-the-wall AC unit in Florida typically costs a few hundred dollars for a simple job, and can reach well over a thousand dollars if your panel needs upgrading or the wiring run is long. The final price depends on your home's electrical panel, the distance from the panel to the AC, and the amperage your unit requires. A licensed electrician can give you an exact quote after a quick look at your setup.

How Much Does It Cost to Install a Dedicated Circuit for a Window or Through-the-Wall AC Unit in Florida? (2026)?

Expect the cost to range from a few hundred dollars for a short, straightforward circuit to well over a thousand dollars for complex work. A dedicated circuit means your AC unit gets its own wire and breaker, so it doesn't share power with other outlets. This is often required for larger window and through-the-wall units because they draw more current than a standard outlet can safely handle.

Several things move the price up or down:

• Distance from the panel. The farther the AC is from your electrical panel, the more wire and labor you'll need.
• Panel capacity. If your panel is full or outdated, you may need a new breaker, a sub-panel, or a panel upgrade, which adds cost.
• Amperage of the unit. Bigger units may need a 20-amp or higher circuit, and sometimes a 240-volt line, which can cost more than a standard 120-volt circuit.
• Wall and access type. Running wire through finished walls, concrete block, or a second story takes more time than an open, accessible run.
• Permits and inspection. Many Florida jurisdictions commonly require a permit and inspection for new circuits, which can add to the total.

Because every home is different, the only way to know your real number is to have a licensed electrician assess your panel and the run.

What homeowners should know

A dedicated circuit protects your AC unit and your home by giving the unit the steady power it needs without overloading shared outlets. Doing the work with a licensed, permitted electrician helps you stay compliant with insurance requirements and local code.

Here are the key points to keep in mind before you book the job:

• Check the unit's requirements first. Your AC's label or manual lists the volts and amps it needs. This tells the electrician what size circuit to install.
• Don't rely on an extension cord or power strip. These are not a safe substitute for a dedicated circuit and can create a fire hazard.
• Ask about permits up front. Many Florida areas require a permit and inspection. A reputable pro will handle this for you and build it into the quote.
• Get the panel checked. If your panel is old or full, factor in the possibility of an upgrade.
• Hire licensed and insured. Electrical work carries real safety risks, so verify credentials before anyone touches your wiring.
