(included system
redesign & zoning
implementation)

Client concerns and goals that we
had to meet

The client just purchased the home and had to deal with the following HVAC problems:

  • Asbestos ducts – Client needed all hazardous materials removed & replaced
  • Rodent damage & infestation – The new mechanical system had to be safe
  • Extreme temperature differences between the floors – The new system needed to be able to control the temperatures between the floors effectively.

Project Challenges

  • The equipment platform in the attic was deteriorating and the service platform did not meet local building code requirements.
  • The existing condensate lines were not routed correctly
  • The attic light did not have a switch at the access and overall lighting was poor
  • Even though this was not an original installation virtually all existing components had to be replaced due to the poor workmanship of the installation
  • The refrigerant lines were incorrectly sized for the new a/c unit
  • Complete duct re-design was required for the zoning application
Project Result
  • Energy efficient (19 SEER) new variable capacity system with greatly reduced operation sound.
  • 2 Zone – Zoning system was installed
  • Greatly improved temperature/humidity control and overall performance.
  • Beautifully re-engineered equipment platform to improve durability and safe service access to equipment.
  • Airflow issues were resolved by re-designing the air duct system and adding several new air supply ducts.
  • A new air return duct system was installed.
  • A Hospital-grade Lennox Pure Air air purification system was added to help improve IAQ as well as eliminate the need for equipment & duct cleaning.
