Viking Heating & Air Conditioning, your family-owned HVAC contractor serving the Phoenix area since 2016, understands these distinct requirements and provides transparent, professional commercial heating services throughout Maricopa County.

Understanding Commercial Heating Systems in Arizona

Commercial heating systems differ significantly from residential units in scale, complexity, and operational demands. In the Phoenix Valley, where businesses operate year-round and customer comfort directly impacts revenue, choosing the right heating system becomes critical for operational success. Viking's commercial HVAC services address these specific needs with solutions tailored to Arizona's unique climate conditions.

The desert climate of Phoenix, Gilbert, Mesa, and surrounding areas presents specific challenges for commercial heating. While heating demands are less intense than in northern states, the temperature swings between day and night can stress HVAC systems. Commercial buildings must maintain consistent temperatures despite these fluctuations, requiring robust systems designed for efficiency and reliability. With over 40 years of combined experience, Viking HVAC's team understands how to optimize heating systems for Arizona's climate patterns.

Commercial heating systems must also accommodate varying occupancy levels, different zones within buildings, and integrate with existing ventilation and air quality systems. Unlike residential systems that serve relatively predictable loads, commercial heating must adapt to changing business operations, from early morning warm-ups to after-hours maintenance schedules. This flexibility requires sophisticated controls and properly sized equipment that balances comfort with energy efficiency.

Types of Commercial Heating Systems

Packaged Rooftop Units (RTUs)

Packaged rooftop units dominate the commercial landscape in Phoenix, Chandler, and Mesa for good reason. These self-contained systems combine heating and cooling capabilities in a single unit, maximizing interior space while providing efficient climate control. RTUs work particularly well for retail stores, restaurants, and office buildings throughout the Valley, where roof space is plentiful and ground-level real estate is valuable.

The modular nature of RTUs allows businesses to add capacity as they grow, making them ideal for expanding Arizona businesses. Viking HVAC specializes in sizing, installing, and maintaining these units to ensure optimal performance during both our brief heating season and extended cooling period. With proper maintenance, RTUs can provide reliable heating for 15-20 years, making them a cost-effective choice for budget-conscious business owners.

Split Systems

Commercial split systems offer flexibility for businesses with specific layout requirements or noise concerns. By separating the indoor and outdoor components, these systems provide quiet operation for customer-facing areas while housing mechanical equipment in less sensitive locations. Many Scottsdale offices and Tempe professional buildings prefer split systems for their aesthetic advantages and operational efficiency.

The ductless mini-split variants have gained popularity in Arizona's commercial sector, particularly for businesses adding heating to previously unconditioned spaces or seeking zone-specific temperature control. These systems eliminate ductwork losses, which can account for up to 30% of energy consumption according to the U.S. Department of Energy, making them highly efficient for our climate.

Heat Pump Systems

Heat pumps represent the future of commercial heating in Arizona, offering exceptional efficiency by moving heat rather than generating it. During Phoenix Valley's mild winters, heat pumps can achieve efficiency ratings of 300-400%, meaning they produce three to four units of heat for every unit of electricity consumed. Viking's guide to commercial heat pumps versus traditional heating explores these advantages in detail.

Modern commercial heat pump technology has evolved significantly, with variable refrigerant flow (VRF) systems providing precise temperature control across multiple zones. These systems excel in Arizona's climate, where heating and cooling demands can vary significantly between sun-exposed and shaded areas of the same building. Queen Creek businesses and Gilbert offices increasingly choose heat pumps for their dual heating and cooling capabilities, reducing equipment redundancy and maintenance requirements.

Gas Furnaces and Boilers

While less common than in colder climates, commercial gas furnaces still serve many Phoenix Valley businesses, particularly in industrial applications requiring high-temperature process heating.
