💰 Safety Disconnect Service Menu

HVAC Fused Disconnect Replacement | $175 – $270 per unit

Protect your central air conditioning compressor or heat pump from devastating power surges with a dedicated, exterior weatherproof safety switch.

Best For: Residential central AC units, heat pumps, and small commercial split ventilation systems.
Included Labor: Safe panel circuit isolation; removal of the old rusted or burned-out box; mounting a brand-new NEMA 3R weatherproof enclosure; installing a premium pull-out block or toggle style mechanism with correctly sized time-delay dual-element fuses; connecting your existing flexible liquid-tight conduit whips; and system voltage testing.
🚨 Scope Note: Pricing includes installing a new disconnect box or replacing a pre-existing one only. It does not include running new circuit wires. If a new circuit run back to the breaker panel is required, please see the New Circuit Run line item below.

Spa & Hot Tub Disconnect Subpanels | $350 – $650 per system

Code-mandatory exterior life-safety disconnects equipped with critical ground-fault protection to keep your family completely safe while using outdoor water amenities.

Best For: Residential hot tubs, outdoor swim spas, and high-voltage pool equipment pumps.
Included Labor: Mounting a weatherproof subpanel within line-of-sight of your spa (and according to strict code distance regulations); wiring a specialized high-amperage GFCI breaker (typically 40A or 50A) into the disconnect box to serve as both your safety switch and shock protector; connecting heavy-gauge line and load conductors; and verifying system ground testing.
🚨 Scope Note: Pricing includes installing a new disconnect box or replacing a pre-existing one only. It does not include running new circuit wires. If a new circuit run back to the breaker panel is required, please see the New Circuit Run line item below.

Air Compressor & Shop Equipment Disconnects | $175 – $350 per unit

Establish instant, manual electrical isolation points for high-vibration industrial shop tools to facilitate safe equipment repairs and routine maintenance.

Best For: Heavy automotive shop air compressors, manufacturing machinery, commercial vehicle lifts, and residential workshop power gear. [1]
Included Labor: Safe high-voltage shutdown; removal of worn or arced electrical boxes; surface mounting of a commercial-grade, heavy-duty safety switch box; terminating thick structural conduit wiring; and testing continuous power distribution under full machinery load cycles.
🚨 Scope Note: Pricing includes installing a new disconnect box or replacing a pre-existing one only. It does not include running new circuit wires. If a new circuit run back to the breaker panel is required, please see the New Circuit Run line item below.

Commercial 3-Phase Safety Disconnects | $450 – $1,200+ per unit

Heavy-duty industrial-grade power management switches engineered to handle high-voltage, multi-phase commercial grid demands without arcing or overheating.

Best For: Commercial HVAC rooftop units (RTUs), industrial motors, large commercial exhaust hoods, printing presses, and commercial kitchens.
Included Labor: Full facility electrical isolation procedures; removal of old, burnt internal mechanical switches; mounting heavy-gauge commercial enclosures; wiring multi-terminal phase blocks (208V, 240V, or 480V networks); adjusting solid-handle throwing arms; and performing phase-to-ground balance validation checks.
🚨 Scope Note: Pricing includes installing a new disconnect box or replacing a pre-existing one only. It does not include running new circuit wires. If a new circuit run back to the breaker panel is required, please see the New Circuit Run line item below.

EV Charger & Appliance Disconnect Upgrades | $200 – $400 per unit

Code-compliant, dedicated electrical isolation points required by local building jurisdictions for high-amperage residential charging points and specialized building appliances.

Best For: Level 2 electric vehicle chargers, commercial tankless water heaters, and large multi-kilowatt indoor appliance systems.
Included Labor: Mapping structural code clearance guidelines; integrating a clean interior or exterior manual safety switch directly into the equipment's dedicated electrical run; secure terminal wiring; and running performance load verification testing.
🚨 Scope Note: Pricing includes installing a new disconnect box or replacing a pre-existing one only. It does not include running new circuit wires. If a new circuit run back to the breaker panel is required, please see the New Circuit Run line item below.

New Circuit Run & Conduit Installation | $150 – $1,800+ per run

Establish entirely new electrical pathways or upgrade existing lines directly from your main electrical panel to your disconnect location.

Best For: Brand-new hot tub installations, newly positioned AC units, warehouse floor plan changes, or replacing degraded, non-compliant wiring.
Included Labor: Installing an appropriately sized circuit breaker into your main panel; mapping a long-distance structural path; pulling heavy-duty or commercial-grade electrical wire through newly installed surface conduit (EMT), liquid-tight whips, or attic spaces directly to the disconnect box.
Pricing Factors: Simpler branch line extensions fall into the $150 – $350 tier, while heavy dedicated panel home runs span $450 – $850. The overall range scales up to $1,800 based on attic space accessibility, commercial high-ceiling runs requiring lift equipment, 3-phase structural power routing, and whether walls must be opened to fish lines.
🚨 Sheetrock Disclaimer: Please note that we do not perform sheetrock repair, patching, or painting. Any wall restoration required after opening up finished sheetrock to fish wires is the sole responsibility of the homeowner.

🛡️ Why Choose a Licensed Electrical Contractor?

Code-Mandated Safety Clearances: Outdated handymen frequently mount disconnect boxes behind appliances or dangerously close to water lines. We execute all work strictly according to local building rules, guaranteeing code clearances and matching line-of-sight safety regulations.
Correct Fuse Sizing: Running wrong-sized or non-time-delay fuses can cause your costly machinery to burn out or trip continuously. We evaluate your equipment's nameplate labels to calculate exact minimum/maximum fuse protection needs.
