North Star Heating and Air Conditioning

We’ve been family-owned and operated since 1998, providing heating, cooling, indoor air quality, and plumbing services from our home base in Dagsboro, Delaware. We serve homeowners throughout Sussex County, including Bethany Beach, Rehoboth Beach, Lewes, Millsboro, and Georgetown, as well as communities on Maryland’s Eastern Shore, including Ocean City, Salisbury, Berlin, and Ocean Pines. We’re fully licensed in Delaware and Maryland, and we remain committed to serving our community with honesty, reliability, and transparent pricing.

Our factory-trained, NATE-certified technicians stay current with the latest HVAC technologies and industry practices. As a Bryant Factory Authorized Dealer, we install and service high-quality, energy-efficient comfort systems. Our work includes heat pump and air-conditioning installation and repair, water heater replacement, indoor air quality improvements, ductless mini-splits, custom ductwork, ventilation, and complete HVAC systems for new construction and commercial buildings. We have also installed dual geothermal water-source heat pump units with insulated ductwork as an energy-efficient solution for year-round heating and cooling.

From our office staff to our field technicians, we share a commitment to providing dependable, cost-effective comfort solutions. We understand that heating and cooling problems do not always happen during regular business hours, which is why we offer 24/7 emergency service. Whether a home needs a struggling air conditioner repaired, a new heat pump installed, a water heater replaced, or better indoor air quality, we bring trained workmanship and attentive service to every project.
