Yes. The electrical supply to the equipment, meaning the circuit, disconnect and any panel work, should be done by a licensed electrician under a permit. Your HVAC contractor handles the equipment and refrigerant side.

It depends on your existing service and loads. Some homes only need a new dedicated circuit and disconnect. Others need a panel replacement or a service upgrade, often to 200 amps. A load calculation tells us which applies.

When the panel has room and the parking spot is near it, most installs take part of a day. Longer runs, panel upgrades or trenching to a detached garage add time, and we’ll tell you up front.

Two-prong outlets, cloth-covered or rubber-insulated cable, knob and tube, frequent breaker trips, flickering lights, warm or discolored outlets and a reliance on extension cords are all signs worth a look.

There’s no single rule, but it’s wise to have it checked when you buy a home, before adding a big load like a heat pump or EV charger, after a storm or surge, or if it’s been many years since anyone looked.

Usually, with the right transfer switch and sizing. We look at your service size and panel and design the connection accordingly.

A standby generator is permanently installed, runs on natural gas or propane, and starts automatically. A portable generator is stored away and connected manually through an inlet and an interlock or transfer switch.

Through a transfer switch or a listed panel interlock that isolates your house from the utility while the generator runs. Never through a backfeed cord, which can endanger line workers.

Commercial appliances and machines often draw heavy or surging loads. Giving them their own circuits keeps one piece of equipment from tripping others and protects the wiring.

Yes. Commercial work often uses conduit or metal-clad cable, serves heavier and more varied loads, and carries additional code requirements.

Replacing fluorescent and HID fixtures with LED, adding occupancy sensors and timers, and zoning controls so lights are only on where they’re needed.

Not always. Hardwired residential detectors are often on a lighting or general circuit, while monitored commercial systems have their own power requirements. We follow what applies to your building.

A surge protector at the panel protects everything in the house, including hardwired equipment like HVAC controls and appliances that plug-in strips can’t reach. It works best alongside point-of-use protection for sensitive electronics.
