Cardinal Plumbing Heating & Air Inc

Cardinal Plumbing Heating & Air Inc has built a formidable reputation across Northern Virginia, earning a 4.9-star rating from 1,794 reviews. Based in Alexandria, the company operates around the clock, seven days a week, providing both plumbing and HVAC services to homeowners throughout Fairfax County, Arlington, and the surrounding communities. Their team handles everything from routine maintenance to complex installations, with particular expertise in navigating the challenges that come with historic properties in the region.

What distinguishes Cardinal from competitors is their commitment to solving problems that other contractors decline. Their technicians regularly tackle installations in older homes where standard solutions simply do not work, drawing on specialized training with brands like Navien tankless water heaters and Zip Hydrotap systems. The company pairs technical skill with meticulous attention to customer communication, ensuring homeowners understand every diagnostic step and repair option before work begins.

Customers consistently highlight specific technicians who go above and beyond. Josh and Kyle recently installed a Navien tankless system in a 200-year-old Alexandria home that three other plumbers had refused to touch. Angelo took on Cardinal's first Zip Hydrotap G5 installation, spending extra time to master the new technology before completing the job. For sewer line repairs, Stephen P provides thorough inspections and fair estimates while Josh makes customers feel like family during the actual work.
