Common Commercial HVAC Heating Systems


Every business relies on efficient, reliable heating to keep employees and customers comfortable during the colder months. At Efficient Mechanical, we specialize in a wide range of commercial heating services, including installation, repairs, and preventative maintenance for all major systems. From rooftop HVAC systems to large-scale boiler repair, our team has the experience and expertise to keep your building warm and energy efficient.


One of the most common choices for commercial properties is the rooftop unit (RTU). These packaged systems combine heating and cooling in one compact design, making them ideal for offices, restaurants, and retail spaces. With their ability to save space and provide year-round comfort, RTUs remain a go-to solution for many businesses.


For facilities like schools, hospitals, and older office buildings, boiler systems and hydronic heating systems are still extremely popular. Boilers can be powered by gas, oil, or electricity and distribute hot water or steam throughout the building. Hydronic systems, which circulate hot water through pipes and radiators or radiant floor panels, are known for their even, comfortable heat and excellent energy efficiency. If your system is aging or underperforming, scheduling a professional boiler repair or hydronic heating service can restore both comfort and efficiency.

Modern businesses are also turning to commercial heat pumps for their flexibility. Available in air-source and water-source models, heat pumps provide both heating and cooling in one system. Water-source designs are especially common in office buildings, often paired with cooling towers and boilers for year-round performance.


In industrial environments, unit heaters and infrared heating systems are the most effective solutions. Unit heaters, which are mounted on walls or ceilings, are cost-effective and perfect for warehouses, garages, and workshops. Infrared (or radiant tube) heaters work differently by directly heating people and objects instead of the air, making them highly effective in large, open spaces like distribution centers.

Summary of Common Commercial Heating Systems

At Efficient Mechanical, we provide commercial HVAC maintenance, repairs, and installations tailored to your business. Whether you need a new rooftop unit, a reliable boiler repair, or expert advice on upgrading to a heat pump, our certified technicians are here to help. Contact us today to schedule your service and keep your building’s heating system performing at its best.
