Commercial HVAC Service in Battle Creek

When a commercial RTU or VRF system needs work, it can be tempting to call the same residential HVAC company that handles your home. While some residential contractors take on a bit of light commercial work, many do not have the training, tools, or staffing needed for larger or more complex projects. Commercial HVAC has different demands than a typical home system for several reasons, including:

• Size: Commercial units must move, filter, and condition air for much larger spaces and higher occupancy levels than residential systems. The components are bigger, heavier, and more challenging to maneuver. Many commercial units weigh several tons and require special lifting equipment along with a different set of tools than those used on home systems.
• Location: In most houses, the furnace is tucked into the basement and the AC condenser sits in the backyard. This split system layout is fairly simple. Commercial equipment is usually installed in a mechanical room, in a basement, or on the roof. Rooftop work in particular brings safety and access concerns that do not exist in standard residential service.
• Economizers: Often described as a secret weapon for commercial HVAC, economizers use sensors and logic controls to bring in cool outdoor air and exhaust warm indoor air when conditions are right. This can lower cooling costs, reduce wear on equipment, and improve ventilation in older buildings. Residential contractors rarely work with economizers, so many have limited experience diagnosing or repairing them.
• Zones: A typical home HVAC system usually serves the entire house at one temperature. Commercial systems are often divided into multiple zones, each with its own controls and packaged equipment. This allows different parts of the building to be set to different temperatures and lets work continue in other areas when one zone is down. The tradeoff is added complexity in both design and service.
• Ventilation: Larger buildings bring more challenging ventilation needs. Many commercial facilities have limited operable windows and must rely heavily on mechanical ventilation to handle stale air and contaminants. Restaurants, gyms, and labs often require significantly higher ventilation levels to maintain safe air quality. Knowing how and where to provide that ventilation is an essential part of commercial HVAC work and is not always a strength of strictly residential companies.
• Cost: A typical homeowner might invest ten to fifteen thousand dollars in a new heating and cooling system. Commercial projects often involve much larger capacities and higher occupancy loads, which makes them more expensive to install and operate. Protecting that comfort investment is critical.
