Can Custom Duct Work Be Done To Fit My Building?

The building that your business occupies for years can prove to your customers that you are here to stay. But what happens when you experience growing pains? Many times a building simply no longer provides what you need. So, now you have some decisions to make. In most cases, a new building is out of the question so you must look deeply into what your needs actually are and compare this list to the existing space and what it could provide in a new configuration.

  • Historically, office space is easy to deal with.
  • However, the comfort level, efficiency and safety of the newly configured space all need to be addressed. When a building is initially designed, the systems tend to be somewhat over-engineered allowing for future expansion and unfortunately a bit less efficiency.
  • In the case of the HVAC system, Rooftop units are easily upgraded to proved additional heating and cooling.
  • In the case of larger buildings with mechanical rooms designated for HVAC equipment, the room and equipment can be reconfigured to meet current needs. Air handling units, pumps and other system components could be upgraded, many times using the existing units by simply increasing capacity. A larger fan motor can provide additional air moving capacity. A pump with a larger motor or even just a differently designed impeller can provide additional water for heating and cooling.

Getting the increased air flow to where you need it!

Upgrading the mechanical room or Rooftop units is all well and good but what about the requirements of the newly reconfigured space? You can assume that the existing ductwork will not be sufficient to handle the new air delivery requirements. Most times, these air delivery requirements are dictated by law for various industries. For example, a laboratory has very different requirements from an office space.

Your HVAC system helps keep the air clean and tempered in your work environment. By law, there are different requirements for “number of air changes per minute” in a space. This keeps the air fresher by venting a portion of the air to atmosphere and replacing it with fresh air.
