Consumer Checklist


A thorough visual inspection is the best way to verify the cleanliness of your heating and cooling systems. All portions of the system should be visibly clean – i.e., such that you cannot see any debris with the naked eye. Have the contractor show you the following areas in your system after the cleaning work to verify that the job was performed satisfactorily:

 Yes
 No
