How to Inspect the Condensate and Drain Components of the Heating System

When inspecting the heating system the inspector should check for the presence of condensation and drain components if there is an air conditioning unit connected to the furnace. It is important to check the piping to make sure that there are no leaks and that they are properly routed to a floor drain or a condensation pump (pictured below). Please review the entire procedure below.

Axium SOP Differences

Axium Requires: The inspector will check the condensate and drain components at the furnace for proper installation.


Tools Needed

No tools required to inspect the Condensate and Drain Components.


While inspecting the heating system we will check the drain line components to make sure they are secured and are not leaking or damaged. There are no pictures for this section unless there is a defect.

Common Defects

  • The condensation drain components for the HVAC system were leaking or damaged.

Common Mistakes

  • Not checking the drain components with your hand to feel if there is any leaking.
  • Not checking to make sure the drain line components are secure.


Report / Software


  • The condensation drain components for the HVAC system was in serviceable condition at time of inspection.


  • The inspector did not have access to the condensation drain components for the HVAC system for inspection.


  • The HVAC system was not configured with condensation drain components.


  • The condensation drain components for the HVAC system were leaking at time of inspection. A qualified contractor should evaluate and repair or replace as necessary.
