No, you won’t need a new electrical panel for a mini-split heat pump installation in Suffolk County. However, you will need a panel modification with a dedicated circuit. Mini-split systems require specific voltage and amperage ratings, depending on the BTU rating.

Here’s what you need to know when you add a mini-split to your home on Long Island.

What’s Commonly Needed for a Mini-Split Heat Pump Installation

When an HVAC contractor visits your Suffolk County home, they will inspect your electrical panel to see if it’s suitable for modification before installing a mini-split heat pump.

• Dedicated Circuit: Mini-splits need their own breaker for a dedicated circuit. Most single-zone residential systems run on a 15-30 amp circuit at 208/240V. Specifics will depend on the size of the system.
• Disconnect Box: In addition to a panel modification, the system requires an outdoor disconnect box under National Electrical Code (NEC 440.14). This small weatherproof box is mounted to an exterior wall near the unit. It allows a technician to cut the power safely during maintenance.

The only time you will need a tandem breaker, subpanel modification, or new electrical panel during installation is if you have no open slots, insufficient capacity on the existing panel, or are installing a large multi-zone heat pump system with a high electrical load.

Your HVAC Contractor Will Coordinate the Electrical Upgrades

You don’t need to call an electrician separately during your mini-split heat pump installation. Reputable Long Island HVAC contractors hold Restricted Electrician licenses to provide in-scope work directly related to installing and connecting HVAC equipment.
