Dedicated circuits, disconnect switches, and panel capacity for central air and ductless AC systems.
Call (416) 828-6976Serving Markham
Markham homeowners increasingly ask us for smart lighting and EV charger installations alongside standard repairs, while local businesses rely on us for ongoing commercial electrical maintenance. Our licensed electricians serve Markham with the same upfront pricing and code-compliant work as everywhere else in the GTA.
In Unionville and Berczy Village, where many homes were built from the 1990s onward, we see more EV charger installations, smart dimmer upgrades, and potlight retrofits than panel replacements. Cornell’s newer new-urbanist homes bring similar requests alongside the occasional builder-grade panel that needs upsizing for a renovation. Around Milliken and Markham’s tech and office corridors, commercial electrical maintenance and lighting retrofits are our most common calls.

More about our work in Markham
Overview
We provide air conditioner electrical installation for homes and businesses throughout Markham, including Unionville, Milliken, Cornell, Berczy Village, and the rest of Markham.
Every central air conditioner and ductless mini-split needs its own properly sized electrical circuit, breaker, and an outdoor disconnect switch, work that has to be planned and permitted correctly, not just wired to the nearest available breaker. We install the dedicated AC circuit, condenser disconnect, and any required whip or conduit for new central air, ductless mini-split, and heat pump installations, and we coordinate directly with your HVAC contractor so the electrical and mechanical work land on the same schedule. Every job is permitted and inspected by the Electrical Safety Authority (ESA) for homes and businesses across Toronto and the GTA.
- Dedicated circuits sized to your AC or heat pump
- Code-required outdoor disconnect installation
- Coordinated scheduling with your HVAC installer
Why It Matters
An air conditioner is a continuous, high-draw load, and running it off an undersized or shared circuit is one of the more common reasons a breaker trips every time the compressor kicks in, or an HVAC installer refuses to hook up a new unit until the electrical is done properly. Ontario Electrical Code also requires a disconnect switch within sight of the outdoor condenser, so a technician can safely de-energize the unit for service without going back to the panel. The other variable homeowners don’t always plan for is panel capacity: adding a 20–60A AC circuit to a home that’s already close to its service limit, especially alongside EV charging or electric heat, can be the thing that actually triggers a panel upgrade, and it’s better to know that before your HVAC installer shows up to a unit that can’t be legally connected yet.
How Air Conditioner Electrical Installation Works
- 1
Load & panel assessment
We confirm your panel has capacity for the new AC or heat pump circuit alongside your home’s existing load, and flag a panel upgrade upfront if it doesn’t.
- 2
Circuit & disconnect planning
We size the dedicated circuit and breaker to the unit’s specifications and plan the outdoor disconnect location required by code.
- 3
Installation & HVAC coordination
We run the circuit, install the disconnect and any whip or conduit to the condenser, and coordinate timing with your HVAC installer so both trades land on schedule.
- 4
ESA inspection & documentation
We pull the ESA permit and schedule inspection, and hand you the certificate of inspection once the work is signed off.
What Affects the Cost
Cost depends on the amperage the unit requires, the distance and routing between your panel and the outdoor condenser location, whether your panel has spare capacity or needs an upgrade first, and whether the job is a straightforward retrofit or new construction rough-in.
Frequently Asked Questions
- Does a central air conditioner need its own electrical circuit?
- Yes. Central air conditioners and ductless mini-splits require a dedicated circuit sized to the unit’s amperage draw, separate from other household circuits, so it isn’t shared with lighting or general-use outlets.
- Do I need a disconnect switch for my AC unit?
- Yes, Ontario Electrical Code requires a disconnect switch installed within sight of the outdoor condenser, so a technician can safely shut off power for service or repairs without returning to the panel.
- Will my panel support a new air conditioner or heat pump?
- It depends on your panel’s existing capacity and load. We assess this before your HVAC installation date and recommend a panel upgrade if the new circuit needs more room than your panel has.
- Do you work directly with HVAC installers?
- Yes, we regularly coordinate with HVAC contractors on the electrical scope for new AC and heat pump installations so the electrical work is ready when the mechanical installation happens.
- Is a permit required to install an AC circuit?
- Yes, new AC and heat pump circuits require an ESA permit and inspection, which we pull and schedule as part of the job.
- How much does AC electrical installation cost?
- Cost depends on the unit’s amperage, the distance from your panel to the condenser location, and whether your panel has spare capacity. We provide a clear quote after assessing your home.
