The electrical side of your AC installation. Done right.
HVAC contractors install the equipment.
The electrical scope: Dedicated circuits, disconnect boxes, and conduit run. Is Pro Call Electric’s job.
For every air conditioning installation, we provide:
- Dedicated 240V circuit: sized to the equipment’s nameplate data (typically 30A, 40A, or 50A depending on unit capacity).
- Disconnect box: code-required within sight of the condenser unit, at the correct setback.
- Conduit and wiring: from the panel through the disconnect to the condenser pad.
- Low-voltage control wiring: thermostat wiring between the air handler and the condenser where needed.
- Panel capacity check: verify the existing panel has room for the AC circuit and if not, we can add a circuit breaker or recommend a panel upgrade if needed.
- Permit and inspection: Alberta Safety Codes Act permit, with inspection before the equipment is energised.
Mini-splits are increasingly popular in Alberta. Here’s what the electrical looks like.
Ductless mini-split systems and heat pumps are common now in Alberta for zone cooling, basement cooling, and all-season climate control.
The electrical scope for a mini-split includes: Pro Call Electric works directly with mini-split and heat pump installers to provide the electrical scope so there’s one coordinated installation process.
- Dedicated 240V circuit (typically 15A to 30A depending on BTU capacity).
- Disconnect: local disconnect near the outdoor unit.
- Low-voltage communication cable: from the indoor air handler to the outdoor unit (usually a 2, 3, or 4-conductor cable).
- Condensate pump wiring (if applicable).
Panel Upgrade for AC
Adding AC to an older Alberta home sometimes means upgrading the panel first.
Many Sherwood Park and Edmonton homes built before 1990 have 100A services that are already close to capacity.
Adding a 30A or 40A air conditioning circuit to an older panel can exceed available capacity or require a panel with no available breaker slots.
Pro Call Electric can evaluate the existing panel, provide options (adding a tandem breaker where CEC permits, or recommending a full service upgrade), and complete the full scope in one visit.
