Heat Pump & HVAC Circuit Wiring in Newnan, GA
A heat pump or air conditioner is one of the largest electrical loads in a Newnan home, and it depends on the right circuit, breaker and disconnect to run safely. Shocking Electric Solutions, Inc. handles the electrical side of HVAC equipment for homeowners in Newnan and Coweta County: new dedicated circuits, outdoor disconnects, whips, breaker replacements and troubleshooting when a unit keeps tripping its breaker. Your HVAC contractor installs and services the equipment itself. We make sure the power feeding it is correct, safe and up to code.
What We Do on HVAC and Heat Pump Circuits
- New dedicated 240-volt circuits for heat pumps, air conditioners, air handlers and furnaces
- Outdoor disconnect replacement when the box is rusted, damaged or burned
- Replacing the flexible whip between the disconnect and the condenser
- Circuits for heat strips (auxiliary or emergency heat) in the air handler
- Breaker replacement when a breaker is worn, overheating or the wrong size for the equipment
- Troubleshooting a unit that trips its breaker, especially on cold mornings
- Panel and service capacity checks before adding a new or larger system
Why the Nameplate Matters
Every outdoor unit and air handler has a nameplate listing its minimum circuit ampacity (MCA) and maximum overcurrent protection (MOCP). Those numbers decide the wire size and breaker size, not a guess or what the old unit had. When a system is replaced with a larger or different unit, the existing circuit may no longer match. We read the nameplate, check the existing wire and breaker, and correct anything that does not fit the new equipment.
The Disconnect Near Your Outdoor Unit
The National Electrical Code requires a disconnecting means within sight of the outdoor unit so the equipment can be shut off safely for service. In Georgia heat and humidity, those boxes rust, wasps nest in them, and the connections inside can loosen and overheat. Signs your disconnect needs attention include a rusted or broken cover, scorch marks, a melted pull-out block, or a unit that runs only when the disconnect is jiggled. These are repairs for a licensed electrician, because the line side stays energized even when the pull-out is removed.
Heat Strips and Winter Breaker Trips
When a heat pump cannot keep up on a cold morning, the air handler turns on its electric heat strips. Heat strips draw a lot of current, and they often run at the same time as the space heaters, dryer and water heater. A heat strip circuit with a worn breaker, loose connection or undersized wire is a common reason a breaker trips in winter. We test the circuit, check the connections at the breaker and air handler, and tell you whether the problem is electrical or something for your HVAC contractor, such as a failed defrost control. See why breakers trip more in winter for more.
Electrician or HVAC Contractor?
Call your HVAC contractor for refrigerant, compressors, fans, thermostats and the equipment itself. Call an electrician for the circuit, breaker, disconnect, whip and panel. Many jobs need both, for example when a new system needs a larger circuit than the old one. We are glad to coordinate with your HVAC company on timing so the power is ready when the equipment goes in.
Warning Signs on an HVAC Circuit
- The breaker for the AC, heat pump or air handler trips repeatedly
- A burning smell or discoloration at the disconnect or panel
- A breaker that feels hot or buzzes
- Lights dim hard every time the outdoor unit starts
- A rusted, open or damaged disconnect box
If you smell burning, turn the system off at the thermostat and call a licensed electrician. Do not keep resetting a breaker that trips over and over.
Permits and Inspection
New HVAC circuits, disconnect replacements and panel work generally require a permit and inspection through the City of Newnan or Coweta County, depending on your address. As a licensed electrical contractor, we pull the permit when one is required.

Frequently Asked Questions
Do you install heat pumps or air conditioners?
No. Your HVAC contractor installs and services the equipment. We install and repair the electrical circuit, breaker, disconnect and whip that power it.
Does a heat pump need a dedicated circuit?
Yes. Outdoor units and air handlers are on their own circuits, sized from the minimum circuit ampacity and maximum overcurrent protection on the nameplate.
Why does my heat pump breaker trip on cold mornings?
Heat strips draw heavy current when the heat pump needs help, so worn breakers, loose connections or an undersized circuit show up in cold weather. We test the circuit to find the cause.
Can I replace my AC disconnect myself?
No. The supply side stays energized, and this is work for a licensed electrician. We replace damaged disconnects and whips.
Will my panel handle a new or larger system?
We check panel capacity before the new equipment goes in and explain your options if an upgrade is needed.
Are estimates free?
Yes. Call (678) 552-9399 or text (470) 516-7261 to set up a free estimate.
