Krafft Service Corporation traces its start to 1940, when John Krafft opened a sheet-metal shop in downtown Washington, D.C. After World War II he reopened in Arlington, Virginia as a heating and cooling company, and the business has stayed in the family across the generations — today it’s led by CEO Jay Krafft and CFO Carol Colza, with many technicians who have been on staff for decades. The company now works out of Alexandria and covers northern and central Virginia (Arlington, Fairfax, McLean, Woodbridge), suburban Maryland, and the District.

The technical range is broad for a family shop. Alongside standard air conditioning and furnace repair, installation, and maintenance, Krafft handles heat pumps, ductless mini-splits, and — less commonly — high-velocity small-duct systems, which suit older homes and tight spaces where conventional ductwork won’t fit. On the commercial side the team services businesses, schools, and churches, from a small light-commercial install to an emergency repair. Indoor air quality equipment and smart thermostat setup round out the list.

Krafft recommends equipment based on precise heat loss/gain calculations rather than rules of thumb, and its fully insured technicians are NATE-certified. The company is an American Standard Authorized Dealer but services all makes and models, backs work with a one-year parts-and-labor warranty, and runs 24/7 emergency service. Financing is available through Wells Fargo.
