HVAC Contractors in Tucson AZ | Air Conditioning and Heating Services

air conditioning

Air Conditioning

A central air conditioning system is made up of four main parts. These include an air handler, evaporator coil, condensing coil, and air ducts. The ducts distribute the air throughout the home. Our HVAC contractors ensure that all of these parts are carefully matched together during the original installation. This ensures the best performance.



Our HVAC contractors install, repair, and service heating systems. These include a Single Speed/Single Stage–a basic furnace. It’s limited in that it only provides a high heat mode. The Two-Speed/Two Stage is technology enables a gas furnace to improve indoor air circulation and overall comfort, while reducing operating noise. It operates at a slower, more consistent level over 90% of the time.

Indoor Air Quality

The U.S. Environmental Protection Agency has ranked indoor air pollution as a high priority public health risk. The World Health Organization and the National Heart, Lung, and Blood Institute concluded that preventing exposure to environmental allergens and irritants may help prevent asthma and related breathing disorders.Talk to our HVAC contractors about your indoor air quality.

central vacuum

Central Vacuum

One in three people in the U.S. have dust-related allergies. The EPA estimates that indoor air is up to five times more polluted than outdoor air. Our HVAC contractors recommend a central vacuum for removing pollutants. Importantly, it removes 100% of pollen, bacteria, pet dander, and odor from the home.

home energy audit

These include air leaks, insufficient insulation, moisture, defective ducts, gas leaks, ventilation, and inefficient lighting and appliances.



Solar panels can be a great investment. Not only can they save you money, but they can also increase the value of your property. Furthermore, they benefit the environment.

Company History

The founder and owner of Intelligent Design, Andrew Dobbins, entered the business in 2002 after serving with honor in the U.S. Marine Corps. He had previously served as Presidential security at HMX-1 in Quantico, VA. The Corps had impressed upon Andrew a great appreciation for attention to detail. This benefited him as he excelled in the fields of product differentiation, heat load engineering, system customization, system design and estimation. Subsequently, Andrew became very proficient in all aspects of residential system design. He accrued several different certifications. These include EPA certification, Building Performance Institute Building Analyst certification, and heat load certification, for example. Finally, Andrew earned his Arizona Registrar of Contractors CR39 residential and commercial HVAC license.

In 2009, Andrew partnered with a gentleman who was a third generation heating and cooling expert. After three years of wonderful growth, Andrew sold his half of the business to his partner. Subsequently, Andrew founded his own company, Intelligent Design. The very first order of business for Intelligent Design was to hire the most qualified HVAC General Manager available who shared Andrew’s appreciation for detail, process, and doing things the right way.
