Plumbing & HVAC in Annandale
More Than 90 Years of Home Service in Northern Virginia
A leaking pipe, unreliable water heater, slow drain, or uneven heating and cooling can point to more than one component in your home. Our technicians assess the reported problem and the related equipment, controls, ductwork, water lines, or drains before discussing the work needed.
Long's Corporation provides residential plumbing, heating, air conditioning, sewer and water services, and indoor air quality solutions for homeowners in Annandale and throughout Fairfax County. We help address immediate concerns while considering the condition of the connected system.
Homes can have different service needs based on their equipment, layout, and maintenance history. We handle individual repairs and discuss related system work when the problem involves connected components.
