A
thorough visual inspections is the best way to verify the cleanliness
of your heating and cooling system. 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 satisfactory.
General
Did
the contractor clean the entire heating and cooling system,
including ductwork and all components?
Heating
Is
the heat exchanger surface visibly clean?
Cooling
Are
both sides of the cooling coil visibly clean?
Components
If
you point a flashlight into the cooling coil, does light shine
through the other side? It should if the coil is clean.
Are
the coil fins straight and evenly spaced (as opposed to being
bent over a smashed together)?
Is
the coil drain pan completely clean and draining properly?
Access
Doors and Covers
Are
newly installed access doors attached with more than justduct
tape (i.e.,screws, rivets, mastic)?
Air
Vents
Have
your air vents been firmly reattached to the walls, floors,
and / or ceilings?
If
you answered "No" to any of the above questions, this
may indicate a problem with the job. Call Dirty Ducts
and get the job right the first time.
