Zapp Electric Inc in Allied Gardens, San Diego, is a residential and commercial electrical contractor founded in 1978 by Dan Hunt Sr., with the business incorporating in 2007 under the current ownership of Dan Hunt Jr. as president. The crew operates from a 92120 base near the intersection of Twain Avenue and the I-8 freeway, putting the trucks within minutes of Allied Gardens, Grantville, Del Cerro, and the College Area corridor along El Cajon Boulevard. HVAC system installations and replacements require dedicated high-voltage circuits and disconnect switches, and Comfort Air Conditioning & Heating in Allied Gardens coordinates the mechanical-to-electrical handoff on furnace and condenser changeouts where Zapp's crew runs the disconnect, whip, and breaker work. The service list covers panel upgrades — a frequent need in Allied Gardens' mid-century homes still running original 100-amp or 125-amp main breaker panels — along with whole-house rewiring, ceiling fan installations, dedicated 240-volt circuits for EV chargers and modern appliances, recessed lighting layouts, landscape lighting, and commercial tenant-improvement wiring. More than four decades of continuous operation under the Hunt family has built the business almost entirely on referral traffic through the 92120 ZIP where Allied Gardens, Grantville, and Del Cerro homeowners cycle through the same electrical-upgrade timeline as their neighbors on surrounding streets. Waring Road's small business district between Orcutt and Zion avenues generates commercial service calls for sign circuits, parking lot lighting, and code-required emergency egress wiring for retail and restaurant tenants. Solar panel arrays and battery backup systems increasingly pair with panel upgrades in the Allied Gardens and Del Cerro hillside neighborhoods, and TAG Roofing & Solar manages the roof-mount and racking scope while Zapp handles the DC-to-AC inverter wiring, production meter installation, and utility interconnection paperwork that SDG&E requires before a residential solar system goes live. The company services La Mesa, Pacific Beach, San Carlos, Clairemont, Scripps Ranch, and Talmadge beyond the core Allied Gardens territory.
