A/C Circuits

Air Conditioner Circuits

Power your A/C safely. Don’t sweat the wiring.

Installing or replacing an air conditioner isn’t just about choosing the right unit. It’s also about making sure your electrical system can safely handle it. Whether it’s a central air system, a ductless mini-split, or a window unit that needs a dedicated outlet, the wiring must be properly sized, protected, and up to code.

At BTE Electric, we install dedicated air conditioner circuits that give your cooling system the reliable power it needs without tripping breakers, overheating wires, or putting your panel at risk.

Why Does My A/C Need a Dedicated Circuit?

Air conditioners draw a lot of power, especially during startup. That’s why the National Electrical Code (NEC) requires a dedicated circuit for any permanently installed air conditioning unit. Sharing the circuit with other appliances can cause overloads or even damage your A/C.

A properly installed A/C circuit provides:

Stable power without interruption
GFCI or AFCI protection (when required)
Correct breaker size for your unit’s load
Outdoor-rated disconnect box for service safety
Wiring sized for the distance and amperage

We coordinate with your HVAC contractor or installer to make sure everything is ready before your new system goes live.

Common Questions About A/C Circuits

Q. What’s Included in an Air Conditioner Circuit Installation?

ANSWER: Every home and unit is a little different, but here’s what a typical A/C circuit project includes:

Site visit and load calculation to size the circuit correctly
Dedicated breaker installed in your panel
Outdoor disconnect near the condenser (as required by code)
Properly sized wire and conduit (often 10–6 AWG depending on load)
Weather-resistant box and fittings
Permit and final inspection

We also check the condition of your panel and grounding system to ensure your home can support the added load.

Q. What Types of A/C Units Need Dedicated Circuits?

ANSWER: We install circuits for all types of residential air conditioning systems:

Central air systems (with exterior condensers)
Ductless mini-splits (single or multi-zone)
Heat pump systems
Window or wall-mounted units requiring 240V circuits
Portable A/Cs needing dedicated 120V outlets
Air handlers or attic units in split systems

If your HVAC system includes a furnace, blower, or electric heat strip, we can wire those circuits as well.

Q. What Does Code Require for A/C Circuits?

ANSWER: Here’s what the NEC typically requires for air conditioning systems:

Dedicated circuit sized to match the nameplate amperage of the A/C unit
Proper breaker type and rating (per manufacturer specs)
Disconnect box installed within sight of the outdoor unit
GFCI protection for outdoor outlets, and sometimes for the A/C itself (depending on local code)
Conduit and wiring rated for exterior and wet conditions
Proper grounding of all metal components and enclosures
Permit and inspection before the system is energized

Skipping any of these steps can result in failed inspections or even a fire hazard. We never skip them.

Q. How Much Does It Cost?

ANSWER: The cost of installing an A/C circuit depends on the location, panel capacity, distance, and type of unit being installed.

Typical price ranges:

Basic 240V A/C circuit install: $600–$1,800
Mini-split circuit installation: $500–$1,500
Panel upgrade (if needed): $1,500–$3,000+
Additional furnace or air handler circuits: quoted case by case

We’ll give you an accurate, upfront quote with no guesswork or inflated numbers.

Q. Can I use an existing outlet or circuit?

ANSWER: Usually not. Most A/C units require more power than a general-use outlet can provide. Using an existing circuit can cause overloads and void the warranty.

Q. Do I need a permit for an A/C circuit?

ANSWER: Yes. Electrical permits and inspections are required to ensure the wiring meets current code and safety standards. We handle all permitting and inspections for you.

Q. How long does it take?

ANSWER: Most A/C circuit installations take one day or less. We’ll coordinate with your HVAC contractor’s timeline to keep everything running smoothly.
