We pride ourselves on our extensive knowledge of air flow requirements up to 120,000 cfm and our ability to generate even larger flow rates using multiple units in the system. Depending on your needs, we can deploy several different system configurations to produce the best results while integrating seamlessly into the overall facility footprint and layout. Our engineers will specify all necessary fans, burners, humidifiers, evaporators, control systems and power distribution components to create the desired climate set points. The years of experience we have in custom designing & fabrication of HVAC systems afford us a vast knowledge of heating and cooling options available to achieve your desired results while maintaining safe operation.

For example, we always supply Class A and Class B emission stacks with indirect fired heating units so that individuals coming in contact with the system will not be burned. We utilize energy recovery units when applicable to lower costs and loads on the system, while allowing the system to comply with ASHRAE requirements. Our systems include PLC control options that allow the operator to perform off site monitoring, tuning and troubleshooting of system anomalies. Once designed, the system is fabricated and assembled so all components or sections can fit on a truck without oversized shipping limitations. The system is installed and tested for performance. We can also provide ongoing maintenance and documentation for your HVAC systems. We look forward to discussing your next custom designed HVAC project!

A high efficiency furnace is one with an AFUE (Annual Fuel Utilization Efficiency) rating of 90 or higher.

This number means that a furnace with an AFUE of 87 would convert 87% of the energy it uses directly to warm air to heat your home or business. Some furnaces have a rating as high as 98.5, so the savings that could add to your energy bill could add up to a lot of money over the lifetime of the unit. Since a high efficiency furnace lasts over twice as long as a traditional unit and needs fewer repairs and less maintenance, that is just one the many ways it will save you money. Once you’ve decided the time is right for a new furnace installation, turn to our expert technicians for free estimates and knowledgeable advice. Consider investing in an Energy Star furnace – systems that have earned the Energy Star label meet stringent energy efficiency regulations set by the U.S. Environmental Protection Agency. Keep these facts in mind about Energy Star: Wondering how Energy Star furnaces achieve this type of performance? These heating systems have high Annual Fuel Utilization Efficiency (AFUE) ratings and higher efficiency blower motors, as well as advanced technologies like modulating heat and variable speed fan motors.
