HVAC Systems

We provide HVAC solutions to ensure an optimum air quality in your premises

Maintaining good indoor air quality requires attention to the building’s heating, ventilation, and air conditioning (HVAC) system; the design and layout of the space; and pollutant source management. 

HVAC systems can have a significant impact on how pollutants are distributed and removed; they can even act as sources of pollutants in some cases, such as when ventilation air filters become contaminated with dirt and/or moisture.

Our team of HVAC experts offer a full range of HVAC services, including:

  • HVAC system inspection
  • HVAC system maintenance
  • HVAC system design, including local exhaust ventilation (LEV) systems
We understand the crucial link between HVAC systems and indoor air quality and always take into account the six key factors:

Ventilation system design

The air delivery capacity of an HVAC system is based in part on the projected number of people and amount of equipment in a building. When areas in a building are used differently than their original purpose, the HVAC system may require modification to accommodate these changes. For example, if a storage area is converted into space occupied by people, the HVAC system may require alteration to deliver enough conditioned air to the space.

Outside air supply

Adequate supply of outside air, typically delivered through the HVAC system, is necessary in any office environment to dilute pollutants that are released by equipment, building materials, furnishings, products, and people. Distribution of ventilation air to occupied spaces is essential for comfort.

Outdoor air quality

When present, outdoor air pollutants such as carbon monoxide, pollen, and dust may affect indoor conditions when outside air is taken into the building’s ventilation system. Properly installed and maintained filters can trap many of the particles in this outdoor supply air. Controlling gaseous or chemical pollutants may require more specialized filtration equipment.

Space planning

The use and placement of furniture and equipment may affect the delivery of air to an occupied space. For instance, the placement of heat generating equipment, like a computer, directly under an HVAC control device such as a thermostat may cause the HVAC system to deliver too much cool air, because the thermostat senses that the area is too warm. Furniture or partitions that block supply or return air registers can affect IAQ as well, and need to be positioned with attention to air flow.

Equipment maintenance

Diligent maintenance of HVAC equipment is essential for the adequate delivery and quality of building air. All well-run buildings have preventive maintenance programs that help ensure the proper functioning of HVAC systems.

Controlling other pollutant pathways

Pollutants can spread throughout a building by moving through stairwells, elevator shafts, wall spaces, and utility chases. Special ventilation or other control measures may be needed for some sources.
