Claim This BusinessBig Red Services delivers HVAC, plumbing, and electrical solutions to homeowners and businesses across New Castle County, Kent County, and Sussex County in Delaware, plus Maryland's Eastern Shore. The company holds a 4.9-star rating drawn from 418 client reviews, reflecting consistent quality in both residential and commercial projects. Operating Monday through Friday from 8 AM to 5 PM, Big Red Services handles everything from new system installations to emergency repairs, serving customers throughout the First State and neighboring regions.
What distinguishes Big Red Services from competitors is their Dryer Vent Guardian specialty, a dedicated focus on dryer vent cleaning and maintenance that most area contractors overlook. The company also offers ductless mini-split installations, giving homeowners flexible zoning options for heating and cooling without traditional ductwork. Their residential plumbing division covers water heater services, drain cleaning, sump pump work, and septic system maintenance, while commercial clients access specialized plumbing and HVAC packages designed for business properties.
Homeowners regularly praise technicians named Mark and Ben for their approachability and skilled work. One customer received same-day assessment of a water heater problem with installation completed the following day, while another homeowner credit Mark for explaining a garbage disposal issue in detail before replacement. Sylvain Tisi's review describes a heat pump system with two indoor units fully installed within days of his initial call, noting the team's dedication to completing the job properly despite the complexity. These named technician experiences appear consistently across reviews, helping customers feel confident about who will arrive at their door.
All five-star reviews reference specific technicians; Mark appears for plumbing work while Ben is named for appliance and HVAC service. Reviewers frequently mention same-day response capability and next-day project completion, with multiple customers highlighting the team's willingness to stay until work is finished properly.
