HVAC Electrical Wiring FAQs
Do you repair or recharge broken air conditioners?
No. We are licensed electricians. We strictly handle the electrical wiring and power supply for HVAC equipment; you will need a mechanical HVAC contractor for refrigerant or mechanical repairs.
Why do I need a separate electrician to hook up my new AC?
Many local municipalities require a licensed electrician to pull the electrical permit and install the high-voltage disconnects, separate from the HVAC mechanic who installs the ductwork and unit.
Does a furnace require a dedicated circuit?
Yes, the National Electrical Code requires furnaces to be on their own dedicated circuit to prevent overloads from other appliances.
What is an AC disconnect box?
It is a weatherproof switch installed on the exterior wall near your AC condenser that allows technicians to completely shut off power to the unit during servicing.
Can you wire a smart thermostat while hooking up my furnace?
Yes, as electricians, we can run the low-voltage C-wires (common wires) required to power modern smart thermostats.
Do mini-splits need 120V or 240V power?
It depends on the size of the unit. Smaller 9K BTU units often use 120V, while larger multi-zone systems require a dedicated 240V circuit, which we expertly install.
Will I need a panel upgrade to install central air?
If you have an older 100-amp panel, adding a large central AC condenser may overload your system, requiring us to perform a panel upgrade first.
How long does it take to wire a new HVAC unit?
Depending on the distance from your main electrical panel to the equipment, the wiring process typically takes a few hours.
