One Call Electrical, Heating & Cooling Service, Inc

One Call Electrical, Heating & Cooling Service, Inc. has operated as a family-owned and locally operated electrical contractor in South Plainfield, New Jersey since 2005, accumulating two decades of service across Middlesex County and neighboring communities including Edison and Piscataway. The company holds a New Jersey electrical contractor license and maintains accreditation with the Better Business Bureau, where it carries an A+ rating. Across 815 client reviews, the company earns a 4.8-star average, with reviewers routinely describing the crew as professional, thorough, and communicative throughout each project.

The contractor specializes in heat pump retrofits, a service that frequently appears in positive reviews as a standalone offering rather than part of a bundled HVAC package. In one instance, technicians removed an electric baseboard heating system and installed a new heat pump with a condenser and air handler, including running new wiring sized appropriately for the upgraded load. This work required coordination between an electrical panel upgrade and the HVAC installation, demonstrating capability in trades that traditionally remain separate. Reviews indicate the company handles financial discussions openly and presents cost-effective options before recommending equipment replacements.

One review credits Preston and his crew for a multi-day project, with the technician returning twice to confirm every detail met code and functioned correctly before leaving the property. Ms. Joann specifically noted their politeness and respectfulness throughout the work, awarding the team ten stars across two households. Another reviewer praised Justin R. and Sergio Z. for keeping the work area immaculate and explaining each step clearly while remaining patient with household pets. A third account describes Osman producing a detailed inspection report and walking the homeowner through every item before discussing financial options. The company does not maintain Saturday or Sunday operating hours, and customers seeking service on weekdays should plan accordingly.
