About D&H Air Conditioning & Heating & Plumbing
D&H Air Conditioning & Heating & Plumbing is a family-owned and operated HVAC contractor serving Tucson residential customers. The company repairs air conditioners, furnaces, and other heating equipment, installs new cooling systems, and provides 24/7 emergency service. D&H says it has remained locally owned since 1959, giving it more than six decades of experience serving Tucson homes through hot summers and chilly winters.
The company's cooling services include emergency AC repair, regular air conditioning service, new air conditioner installation, and maintenance through its Family Maintenance Plan. D&H works with air conditioners, mini-splits, gas furnaces, and heat pumps, and says its technicians have worked on all makes and models, except systems that are too old for replacement parts to be found and swamp coolers, which the company no longer repairs. When a very old system is no longer a practical repair candidate, D&H can provide an estimate for replacement. Its certified specialists calculate the cooling load a home needs and recommend a system based on the property and the customer's budget.
Heating services include furnace repair, heater repair, heating installation, and maintenance. The company describes furnace repairs involving ignition failure, inducer faults, burner issues, cracked heat exchangers, limit-switch trips, gas-valve faults, blower failures, and combustion-air problems. Heater service also covers heat pump refrigerant-circuit concerns, electric-heat relay failures, and thermostat control faults. In addition to heating and cooling, D&H lists plumbing services, cost-saving insulation, and indoor air quality testing and improvement among its offerings. Its indoor air quality work includes recommendations for filters and HVAC filtration systems, with attention to differences in dust and pollution levels across the Tucson area.
D&H places emphasis on the process surrounding a service visit as well as the repair itself. The company says its HVAC technicians are fully vetted, NATE-certified, and continuously trained in HVAC technology and customer service. Its stated service standards include timeliness, courtesy, professionalism, efficient work, clear information before and after inspections, cleanliness, and fair labor and parts costs. Technicians are expected to leave no mess behind, and customer service calls after each visit to ask whether the work met expectations. D&H also identifies itself as a qualified Pearl Contractor, offering options intended to improve home energy efficiency and protect indoor health. Pearl Certification may also help homeowners maximize a property's appraisal and market value when selling or refinancing.
The company's Tucson roots are central to its service area and community identity. D&H lists Tucson, Casas Adobes, the Catalina Foothills, Catalina, Green Valley, Marana, Oro Valley, Saddlebrooke, Sahuarita, and Vail among the areas it serves. Its website also notes an A+ rating with the Better Business Bureau, a 4.8-star Google rating, and an Angi Super Service Award received in 2024 with an overall 4.8-star rating. For urgent heating or cooling problems, D&H maintains 24/7 emergency service, with trucks on the road during the day and certified HVAC technicians on call at night. Homeowners can begin by scheduling a technician or requesting an estimate for repair, maintenance, installation, plumbing, or indoor air quality work.
