TSSA certified HVAC technicians will replace existing furnace with a new unit using proper techniques and tools as suggested by the manufacturer.
Procedure:
- Do a proper load calculation of the home.
- Check to make sure the ductwork is properly sized to facilitate the airflow of a new system.
- Measure the physical area that the new furnace will be installed
- Check gas lines and electrical wiring to ensure that they’re set up properly for the installation.
- Depending on the furnace chosen, a new chimney flue liner or PVC drain line may need to be installed.
- Depending on the air conditioner that’s already installed, it may necessitate a certain type of equipment so that the two are compatible.
