How to (NOT) Inspect the AC Evaporative Coils

When the inspector is inside of the home and inspecting the heating system they should switch back over to the Cooling System section of the report. This is where the inspector will want to go to the AC Evaporative Coils section and select “Not Inspected” since we are not able to see the coils. You would only call this out as a defect if for some reason the coils are showing and you can see a defect. Please review the procedure below.

 

NACHI SOP

International Standards of Practice for Performing a General Home Inspection

 

3.5. Cooling

 

I. The inspector shall inspect:

N/A

 

II. The inspector shall describe:

N/A

 

III. The inspector shall report as in need of correction:

B. If the cooling system was deemed inaccessible.

 

IV. The inspector is not required to:

E. Examine electrical current, coolant fluids or gases, or coolant leakage.

 

 

Axium SOP Differences

Axium Requires: The inspector will almost always use the “Not Inspected” statement for this section and take a picture of the outside cover where the AC Evaporative Coils are located behind. This is usually going to be right above the furnace and you’ll be able to see the refrigerant lines going into the location.

 

Tools Needed

No tools required to inspect the AC Evaporative Coils.

Procedure

  • The inspector will almost always use the “Not Inspected” statement for this section and take a picture of the outside cover where the AC Evaporative Coils are located behind. This location is usually going to be right above the furnace and you’ll be able to see the refrigerant lines going into the location.

Common Defects

  • Evaporator coil is leaking and could possibly have a drain that is blocked.

 

Common Mistakes

  • Forgetting to take this picture while you are inspecting the heating system.
  • Not using the “Not Inspected” comment since we can’t see the evaporative coils.

 

Report / Software

IN


  • N/A

NI

  • The air conditioning system evaporator coils were located inside furnace ductwork and were not accessible for inspection.

NP

  • The HVAC system did not have an evaporator coil installed.

RR

  • The evaporator coil appeared to be leaking at the time of the inspection. This condition is an indication that the condensate drain is blocked. A qualified contractor should evaluate and repair or replace as necessary.
