What Are Duct Installation Services?
Duct installation services involve the planning, supply, routing, installation, connection, insulation, sealing, testing, modification and maintenance of ductwork used to move air through a building or facility.
Ductwork forms an important part of many HVAC and ventilation systems.
A properly designed and installed duct system can help distribute or extract air between:
- Air-conditioning equipment
- Air handling units
- Ventilation fans
- Inline duct fans
- Exhaust systems
- Grilles
- Diffusers
- Fresh-air intakes
- Return-air points
- Extraction points
- Other HVAC equipment
Duct installation is therefore more than simply connecting pieces of duct together.
The ductwork needs to work as part of the complete HVAC system.
