D&H Air Conditioning & Heating & Plumbing

D&H Air Conditioning & Heating & Plumbing has operated from Tucson since securing ROC-37R 358459, the state contractor license that authorizes both HVAC and residential plumbing work under one roof. The company maintains a 4.8-star average across 163 verified reviews, a volume rare for independent contractors in the Tucson market. Headquartered on South Evans Boulevard with a secondary office near Oracle and Ina Road, D&H serves residents across northwest Tucson, Oro Valley, Marana, Catalina Foothills, Saddlebrooke, Vail, and Sahuarita, offering 24/7 emergency availability across every day of the week.

What separates D&H from neighboring HVAC shops is their in-house capability: their Evans Road facility houses warehousing, sheet-metal fabrication, and technician training, meaning most duct modifications and custom installs avoid subcontractor delays. The company carries industry brands including Daikin, Lennox, Trane, Carrier, and Rheem, and their technicians hold NATE certification for both heating and cooling systems. They also offer a Family Maintenance Plan that bundles seasonal AC tune-ups with plumbing inspections, plus access to IRA tax rebates on qualifying energy-efficient equipment installations.

Customer stories from recent reviews name specific technicians. Merlin performed a thorough preseason evaluation on a Carlson system, explaining options to extend the unit's lifespan. When Stephen Maltzman's thermostat failed during cold weather, D&H dispatched two technicians who completed the repair in just a few hours. Sarah Miller's review documents a contentious warranty claim involving a new system installation with persistent leaks, noting delays in parts acquisition and communication, her review describes the experience as disorganized and the resolution as incomplete.
