HVAC Systems

Typically, the heating, ventilating and air conditioning systems in buildings are only noticed when comfort conditions are not met. Many HVAC system defects exist that are not readily observed by the building occupants even though indoor temperature conditions seem normal. Hidden within the air handling equipment and in the air distribution ductwork are sites for potential problems that can lead to indoor air quality issues. Corroded and dirty ducts and equipment provide breeding grounds for microbial and fungal growth. Malfunctioning outside air dampers and controls can result in deficient supply of fresh air to the building occupants or excessive fresh air that increases the energy load.

Deferred maintenance in HVAC has exponential, negative effects such as:

• Higher energy costs
• Higher maintenance costs
• Frequent breakdowns/tenant dissatisfaction and suppressed building appraisal value.

ABB can evaluate, design, and manage the refurbishment or replacement of old or outdated HVAC systems.
