HVAC & Mechanical Equipment Wiring & Controls
Electrical connections for heating, cooling and ventilation.
Installing a heat pump, replacing an air handler or connecting mechanical equipment? We provide the circuits, disconnects and control wiring needed, and investigate electrical faults in existing systems.
Electrical Wiring and Controls for Residential, Commercial & Industrial Equipment
Heat Pump & Air Conditioning Wiring
Provide electrical circuits and connections for indoor and outdoor units, based on equipment ratings and installation requirements.
Air Handlers & Ventilation Wiring
Connect air handlers, ventilation equipment and exhaust fans, with supply and control requirements reviewed.
Thermostat & Control Wiring
Install compatible thermostats and control wiring, following equipment diagrams and agreed control functions.
Circuits, Disconnects & Protection
Install suitable circuits, disconnects and circuit protection, with required grounding and bonding.
Motors, Pumps & Drive Connections
Provide electrical connections for motors, pumps and variable frequency drives, following equipment requirements.
Electrical Fault Finding & Repairs
Investigate power loss, breaker trips and electrical control faults affecting HVAC or mechanical equipment.
Plan the Connection Before Installation
Match the Equipment
The electrical connection must match the equipment. We review the model, nameplate ratings, available electrical capacity and manufacturer instructions before confirming the installation scope.
Coordinated With Your Installer
We coordinate the electrical work with your HVAC or mechanical contractor as required.
How to Get Started
- Property address and type
- New installation or fault symptoms
- Equipment model, if known
- Installer details, if applicable
- Accessible equipment nameplates
- Panel exterior and work area
Review the request and equipment details. Identify any missing specifications and confirm whether a site assessment is required.
Share available installation manuals or drawings. Arrange assessment access and review the proposed scope, cost and schedule with any other trades involved.
Review electrical capacity, supply requirements, circuits, disconnects and controls. Confirm wiring routes, permit requirements and coordination with the equipment installer.
Approve the scope and arrange access and any agreed shutdown. Coordinate equipment placement and startup availability with the HVAC or mechanical installer.
Obtain required permits, complete the agreed wiring and connections, test the electrical installation and controls, coordinate inspections and support startup with the installer as agreed.
Helpful photos: Send safely accessible nameplates and exterior views. Leave electrical and equipment covers closed. Photos of both indoor and outdoor units help us review split-system requirements.
Frequently Asked Questions
Will a heat pump or new equipment require a panel upgrade?
That depends on the existing electrical capacity and the equipment requirements. We assess the proposed load and available circuits, then explain whether an upgrade is needed before work begins.
Can you work with my HVAC or mechanical installer?
Yes. We coordinate the electrical supply, disconnects and agreed control wiring with the installer, using equipment specifications and a confirmed work schedule.
