Keeping Your Long Island Home Cool This Summer
❄️ Central Air Conditioning Wiring
Central air systems draw significant power and require a dedicated electrical circuit, proper disconnect, and code-compliant wiring to run safely. We handle everything from running new lines to updating breaker panels, ensuring your central AC unit operates reliably—without tripping breakers or overloading your system.
Whether you’re installing a brand-new unit or replacing an old one, we’ll make sure the wiring is done right the first time.
🌀 Ductless Mini-Split & Split System Wiring
Installing a split system or mini-split AC? These units may look simple, but the electrical side requires expertise. Each indoor head and outdoor condenser needs to be properly powered and grounded.
Haines Electric wires ductless systems according to manufacturer specs and NYS code, making sure your investment runs smoothly and safely all summer long.
🔲 AC Disconnect Box Installation & Upgrades
Every outdoor AC unit in Nassau County is required to have an accessible disconnect box—this is a safety must, not a suggestion. We install and upgrade disconnects (both fused and non-fused) to ensure your system is serviceable and compliant with code.
If your current setup is outdated, corroded, or improperly mounted, we’ll replace it with a professional-grade disconnect that keeps you and your system safe.
❓ Air Conditioner Wiring – Frequently Asked Questions
Do I need an electrician to install an air conditioner?
Yes — while HVAC professionals install the cooling system itself, only a licensed electrician should handle the electrical wiring. We ensure your AC is safely connected, properly grounded, and meets all Nassau County electrical codes.
What’s an AC disconnect box, and do I need one?
An AC disconnect box is a safety switch installed near your outdoor unit. It allows technicians to cut power during service or emergencies. It’s required by code in most homes and is a standard part of any new installation or upgrade.
Can Haines Electric wire ductless mini-split systems?
Absolutely. We regularly wire mini-split and split systems, ensuring each unit is powered properly with dedicated circuits, disconnects, and code-compliant connections.
How much does AC wiring cost?
Costs vary based on your panel capacity, distance to the unit, and whether a disconnect or circuit upgrade is needed. We provide clear, up-front pricing after a quick assessment — no surprises.
Do you coordinate with HVAC installers?
Yes — we work closely with HVAC contractors to make sure the electrical portion of your AC install is done at the right time and to spec. We’ll handle our part so everything runs smoothly.
