Start with the equipment schedule
Share the exact indoor and outdoor equipment models and the installer’s electrical requirements. Different mini-splits, air conditioners, heat pumps and air handlers can have different supply arrangements. We use the specified equipment information to plan the circuit and connection, rather than sizing the electrical work from the room size or cooling description alone.
Outdoor units and indoor equipment
Tell us where the equipment will be installed and how the electrical route reaches it. An outdoor unit may involve exterior exposure and a disconnect location; indoor equipment may need access through an attic, mechanical room or finished space. We define which connections belong in Guardian’s scope and which controls or interconnections are handled by the HVAC installer.
Electric heating and garage projects
Electric heaters, baseboard heat and shop heating equipment also need a supply suited to the selected model. Include other planned garage loads, such as tools or EV charging, in the discussion. We review the combined demand and distribution before committing to another circuit. A subpanel may help organize circuits but does not itself increase the utility service capacity.
Replacement equipment and existing wiring
A replacement system can change the electrical requirements even when it serves the same rooms. We assess whether the existing circuit, disconnect and connection are appropriate, and quote corrections if needed. Tell us about previous tripping, damaged exterior components or an installer’s electrical repair list. Repeated trips should be investigated rather than addressed by increasing breaker size.
Coordination and service scope
Refrigerant, ductwork, condensate drainage, mechanical installation and equipment commissioning require coordination with the relevant installer. Guardian’s proposal identifies the electrical work, access needs and power interruption. For a cooling or heating failure, explain any electrical symptoms and share the HVAC technician’s findings so the correct work can be scheduled.
Guardian serves homes and businesses in Myrtle Beach, Carolina Forest, all of Horry County and all of Georgetown County. We travel to your property; share the address and scope so we can discuss the next step. See our service areas.
Questions about electrical circuits for mini-splits, hvac and electric heat
Do you install the complete mini-split system?
This page covers electrical circuits and connections. Mechanical installation, refrigerant and HVAC commissioning must be arranged with the appropriate contractor.
Can you add power for a garage heater?
Yes. Send the heater model, location and other planned garage equipment so we can review the electrical scope.
Can the existing air-conditioner breaker stay?
That depends on the new equipment requirements and the existing installation. We assess compatibility before deciding what can remain.
