Claim This BusinessA Supreme Heating & Air Conditioning has earned a 4.9-star average across 379 client reviews in Glen Burnie, Maryland. The company operates seven days a week with standard business hours, serving homeowners throughout Anne Arundel County and surrounding Baltimore communities who need reliable heating and cooling without navigating a maze of subcontractors. Customers call A Supreme for projects ranging from single-piece replacements to full forced-air and boiler system upgrades, and the volume of repeat referrals and word-of-mouth recommendations visible in local neighborhood groups reflects consistent execution over years of operation.
What distinguishes this contractor is an approach that reviewers repeatedly describe as honest and pressure-free. Jeremy Goldman's account of a heat pump and air handler installation specifically notes the team recommended equipment appropriate to the house rather than padding the invoice, with no upselling. Mark Rao's system-wide replacement included quality equipment at a competitive price, and the crew even accommodated a request to raise the outdoor unit mounting height. New installations carry a one-year complimentary service agreement that includes 24-hour emergency response, and the quoted price covers haul-away of all decommissioned equipment, eliminating a logistical headache that falls to the homeowner with many other contractors.
Two named technicians stand out in customer accounts. DJ appears in Dead Goon's review as the point of contact who arranged same-day Monday installation of a water heater after a Friday deposit. Jeremy Goldman's heat pump installation began with a same-day callback after his heating system failed, and the crew completed multi-point verification testing before leaving the property interior and exterior spotless. Mark Rao received a Mother's Day chocolate from the office after a single-day system-wide replacement, a gesture that signals a customer-relations culture beyond the transaction itself.
With 379 reviews averaging 4.9 stars, customers consistently praise quality equipment, fair pricing, and professional crews. Dead Goon and Jeremy Goldman each describe responsive same-day communication, and five-star accounts across three years mention no upselling and clean job sites. One review flags a potential ownership or partnership change, warranting a direct confirmation call before booking.
