About Service 1 Plumbing, Heating & A/C, Inc.
Service 1 Plumbing, Heating & A/C, Inc. operates as a residential HVAC specialist serving Woodridge, Illinois, and surrounding communities in DuPage County. With a 4.9-star rating drawn from 36 verified client reviews, the company has cultivated a reputation for responsive service across heating, cooling, and plumbing systems. The business maintains extended operating hours seven days a week, beginning as early as 5 AM on weekdays and accommodating Saturday and Sunday appointments for homeowners facing urgent climate control failures.
Unlike larger corporate HVAC chains that delegate service calls to third-party technicians, Service 1 employs in-house specialists including the named professionals referenced in client feedback: John, Brandon, and Randy. The company handles full-system replacements, ignitor switch repairs, blower motor installations, and preventive maintenance inspections. Client testimonials highlight transparent diagnostic processes where technicians share equipment readings directly with homeowners, supporting informed replacement decisions rather than aggressive upselling.

Eight-three percent of reviewers awarded five stars, with recurring praise for same-day response times and specific technician expertise. One negative review cited billing transparency concerns, while positive reviews emphasized diagnostic thoroughness and respectful communication.
