The correct answer is that the NADCA standard recommends verifying the condensate pan and drain for proper drainage prior to Type 2 Coil Cleaning. This step is essential for ensuring that the condensate water generated during cooling processes can flow freely without obstruction. If the drain is blocked or improperly functioning, it can lead to water accumulation and create an environment conducive to mold growth, which can compromise indoor air quality.

Verifying proper drainage also ensures that during the cleaning process, water that is used for cleaning the coils does not back up into the system, potentially causing damage or additional maintenance issues. This proactive measure is crucial in maintaining the efficiency and longevity of the HVAC system, as well as preventing issues that could arise from improper drainage.

The other options, while they may be components of overall HVAC maintenance, do not address the specific recommendation related to drainage as outlined by NADCA.
