Commercial HVAC FAQs

Not Sure Where to Start? Start with the Right Questions.

From chiller selection to service support, these answers help engineers, contractors, facility teams, and owners understand which Dunham-Bush USA path may fit their project.

The right system depends on your facility type, cooling or heating load, available space, efficiency goals, infrastructure, and whether the project is new construction, replacement, retrofit, or expansion. Dunham-Bush USA can help evaluate your project requirements and route you toward the right product path, including water-cooled chillers, air-cooled chillers, heat pumps, airside solutions, packaged systems, or specialty products.
Air-cooled chillers reject heat through outdoor air and do not require a cooling tower, making them a common fit for projects with limited water infrastructure or simpler installation needs. Water-cooled chillers use water and typically require cooling towers and supporting systems, but they are often selected for larger facilities and applications where efficiency, capacity, and long-term performance are key priorities. The right choice depends on your facility, available space, efficiency targets, maintenance requirements, and total operating cost.
A custom or specialty solution may be appropriate when a project has non-standard performance requirements, unusual space limitations, mission-critical uptime needs, industrial or process cooling demands, retrofit constraints, or application-specific design conditions. These projects often require more than an off-the-shelf product and benefit from engineered support early in the selection process.
Energy performance starts with proper system selection, sizing, controls, and application fit. A system that is matched to the building's real operating conditions can help reduce wasted energy, improve long-term performance, and support sustainability or code-compliance goals. Dunham-Bush USA can help compare product options around capacity, efficiency, controls, and project requirements.
Yes. Dunham-Bush USA supports customers across North, Central, and South America through product guidance, local contact routing, authorized service, and warranty support. For project-specific questions, the best starting point is to connect with a local contact or submit a request so the team can route you to the right support path.
For new projects, product selection, specifications, or application questions, start with Request a Quote or Find Your Local Contact. For existing equipment, service needs, warranty questions, or technical support, use the Dunham-Bush USA support path for service support, warranty information, or contact routing.
Custom industrial chiller design provides flexibility around cooling capacity, temperature range, footprint, controls, materials, redundancy, environmental conditions, and integration with existing process equipment. Dunham-Bush USA can help evaluate application requirements and develop a tailored solution when standard equipment does not fully address the project's performance, space, reliability, or operating needs.
