Air Conditioner Electrical Installation in Markham

How Air Conditioner Electrical Installation Works

1. 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. 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. 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. 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.

Frequently Asked Questions

Our Unionville home already has central air — what does a heat pump conversion involve electrically?

Usually confirming whether the existing circuit and breaker are sized for the heat pump’s higher amperage, since heat pumps generally draw more than a straightforward AC condenser.

Cornell’s lots feel narrower than other Markham neighbourhoods — does that limit condenser placement?

It can. Rear laneway lots sometimes leave less side-yard space than a standard subdivision, so we plan the disconnect and condenser location around code clearance from property lines and windows before installing.

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.
