Nightingale Air

Nightingale Air is a licensed HVAC contractor headquartered in Washington, DC, with three perfect 5-star reviews from homeowners who needed creative climate solutions for challenging residential properties. The team specializes in older homes, particularly historic rowhouses and century-old residences, where standard central air systems struggle to maintain consistent comfort across multiple floors. They serve clients throughout the DC metro area, including neighborhoods in Dupont Circle, Adams Morgan, and Capitol Hill where housing stock regularly exceeds 80 years in age.

What distinguishes Nightingale Air from typical HVAC companies is their focus on the Quilt zoning system, a ductless mini-split solution that addresses the common problem of temperature imbalance in multi-level homes without requiring extensive ductwork. Two reviewers specifically mention the Quilt units as transformative, noting the system is energy efficient, operates quietly, and integrates visually into historic interiors. Additional expertise includes radiant floor heating installation, particularly for guest suites and basement spaces, and whole-home humidity management to protect both human comfort and houseplants.

Homeowners repeatedly mention technicians Brad, Brian, and Khyree in connection with specific problem-solving scenarios. One reviewer describes how the team resolved extreme upper-floor heat in summer by installing Quilt units in upstairs bedrooms, a problem her central air could not overcome. Another notes the recommendation for radiant heating in a basement guest suite to ensure visiting parents remain comfortable year-round. Both mention the crew arrived as promised, completed work efficiently, and left the workspace immaculate.
