Is visual proof needed before I write a check?

Your cleaning company should offer proof your system is clean by offering visual proof the system is clean-using visual, video or photo proof before you write them a check.

Some companies offer to show you how much debris came out of the system. Some companies send you a photo in the mail of one part of the system that’s easy to get to. Don’t be fooled. The photo could be someone else’s system, and your system could still be dirty.

Demand that you be shown visual proof for at least 14 critical areas that don’t usually get cleaned:

2 supply branches — full length
2 return branches — full length
Supply trunk line — full length
Return trunk line — full length
Motor/blower assembly
Blower compartment
AC evaporator coils — Top
AC evaporator coils — Bottom
Heat Exchanger — Top
Heat Exchanger — Bottom
Condensate Drain Pan
Burner Compartment

Without definitive proof that these areas are CLEAN, you could be left with a system that is just . . . LESS FILTHY! (Back to top of page)
