AC Installation vs. Panel Upgrade: What Comes First?
Installing a new air conditioner often requires more electrical capacity than your panel can provide. Learn whether you need a panel upgrade before AC installation.
A central air conditioning system draws 15–60 amps depending on size (2–5 tons), and it needs a dedicated 240V circuit. Many older homes have 100-amp or even 60-amp electrical panels — barely enough for existing loads, let alone a new AC compressor. If your panel is already near capacity, turning on the AC can trip breakers or create a fire risk from overloaded circuits. An HVAC technician installs the AC unit, refrigerant lines, and thermostat wiring, but they cannot legally modify the electrical panel — that requires a licensed electrician. In most cases, you should have an electrician assess your panel capacity before the AC installation appointment. If an upgrade is needed (typically from 100A to 200A), it's far cheaper and easier to do it before the AC goes in, since the electrician can run the dedicated circuit during the same job. Doing both simultaneously saves $200–$500 in trip charges. A panel upgrade costs $1,500–$3,500; AC installation costs $3,000–$7,000. Combined, expect $4,500–$10,000 with coordinated scheduling.

| Best for | Choose AC installation first when your panel has ample spare capacity (200A panel with available slots and headroom). A typical 3-ton central AC needs a 30-amp, 240V dedicated circuit. If your panel already has an open double-pole slot and the load calculation shows room, the HVAC installer can coordinate with an electrician to pull the circuit without a full panel upgrade. AC installation costs $3,000–$7,000 depending on tonnage, SEER rating, and ductwork condition. | Choose a panel upgrade first when your home has a 100A or smaller panel, when breakers already trip under heavy loads, or when the panel uses obsolete technology (Federal Pacific, Zinsco, fuse box). Upgrading to 200A gives you capacity for the AC plus future needs (EV charger, heat pump, hot tub). Panel upgrade costs $1,500–$3,500 and typically takes a full day. Many jurisdictions require a permit and utility coordination for the upgrade. |
