About JHACS Electric Inc.
JHACS Electric Inc. is an electrical contractor serving Mineola and nearby communities across Nassau County. The business holds a 4.0-star rating from 31 customer reviews, with a strong reputation for generator installations, EV charger setups, and general electrical repairs. Customers report that phone calls are answered promptly by a knowledgeable office team, and service requests are handled with attention to homeowner needs. The company operates Monday through Friday from 8 AM to 5 PM, providing scheduled appointments for installations and maintenance work.
What distinguishes JHACS Electric is their commitment to quality control and transparent communication. Multiple reviewers note that the team inspects new equipment upon delivery, refusing to install damaged units and arranging replacements rather than proceeding with flawed products. The company offers annual service contracts that include two maintenance visits per year, a detail several customers cited as a deciding factor. Workmanship is described as thorough, with crews leaving homes in pristine condition after installations. The business provides upfront pricing and has demonstrated willingness to competitive shop against alternative suppliers.
Customer stories highlight specific technicians who managed complex situations. One reviewer described working with Chris, who provided a quote and coordinated the generator installation process. Another customer mentioned the team identified and resolved issues that arose during their work. The office staff manages scheduling and customer inquiries, with reviewers consistently noting responsiveness and clear communication throughout their service experience. These interactions have earned repeat business and referrals from satisfied homeowners.

The single 2-star review cited pricing concerns while acknowledging quality work, creating a mixed sentiment around value versus quality.
