Air Duct Installation Houston, Texas

Central heating and cooling systems use an air or duct distribution system to circulate heated and cooled air through all air-conditioned rooms in the home. Even when properly designed, duct systems must be properly installed to be efficient, maintain uniform temperatures throughout the home, run quietly, and not adversely affect the comfort or indoor air quality.

Importance Of Air Duct Cleaning

The objectives of a properly designed and installed duct system are the comfort of the occupants, adequate air distribution, economical operation of heating and cooling systems, and economical installation of ducts. Such a duct system is the one that;

  • Provides air conditioning to meet all heating and cooling loads in the room.
  • Ensures that the pressure drop in the air handling unit conforms to the manufacturer’s specifications and design.
  • Provides adequate airflow.
  • Prevents air from entering the house or duct system from polluted areas.
  • Maintains a neutral pressure in the house through a balanced airflow between the supply and return systems.
  • Minimizes air temperature gains or losses in ducts between the air handling unit and the supply vents, and between the return damper and the aerator.
When designing the duct system, duct configuration and location is identified. The isolation levels are calculated, and the registers are selected. The installation of the sheath ensures that the design of the sheath is carried out in practice taking into account three critical elements:
  • Mechanical integrity: the system will remain as built for the life of the house, without developing leaks, obstruction, or failure of insulation.
  • No leaks – all air moved by the air handler will be drawn and delivered to the conditioned spaces provided.
  • Good insulation – air conditioning does not exchange heat with non-conditioned spaces.

Installation Process Of Air Ducts

On the day of installation of your central air duct, expect a process similar to the one described below. Of course, the actual steps may vary from one contractor to another.
  • If your district local authority requires authorization for HVAC work, your contractor will obtain the authorization or will have informed you that you must take care of it. In most cases, your contractor will do it for you.
  • The contractor dismantles and removes the existing air duct structure.
  • The contractor installs new duct systems or performs duct repair.
  • Prepare the installation site. This may involve placing a concrete base outside to support the air conditioner or installing roof supports for a conditioned system installation.
  • Your new outdoor unit will be correctly positioned. The contractor will install and secure it on the site.
  • If you are also replacing your air handler, install the indoor unit. While it is a good idea to replace the indoor and outdoor units at the same time, in some cases you may choose not to replace the air handler when a new outdoor unit is installed.
  • Connect the indoor and outdoor units. The contractor will determine the appropriate size for refrigerant lines, drain pipes, and power lines. Some of these components connect parts of the split system.
  • Connect the thermostat to the central air duct. You may have a new thermostat installed or continue to use your existing device.
  • Pull a vacuum to remove contaminants from the refrigerant lines and charge the new central air duct with refrigerant.
  • The new cooling system starts and works.
  • The contractor will perform an inspection of the facility to ensure that the installation has been completed correctly and that the system is operating properly.

Conclusion

For safety reasons, the technician should be informed of the location of the fire extinguisher and the first aid kit. It is best to provide them with emergency contact information. Duct installation can be noisy. It is best to do this when most family members are not present. Clear the work areas. Ask your technician how much space is needed around each vent and how much space will be needed around the furnace and air duct. It is best to clear these areas in advance. Before installation, take a guided tour of your home to see where protective coverings such as fall protection and corner guards will be placed. It is also necessary to review the HVAC system and its accessibility.
