Restricted air flow
M
ACS member Gordon Marks of Marks Air Inc. in Tampa, Florida sees a lot of business in his bays during
the summer months. He shared these photos of a job
where the customer was complaining about restricted air flow in
his 2005 Ford truck. The evaporator was full of the type of leaves
(live oak) you see in the picture and was also leaking. Restricted
air flow, indeed.

It's probably a good bet you've never seen an A/C system in
this condition. When the technician set out to work on this 2005
International 4200 truck, they discovered there was considerable
restriction to the airflow. It turns out the truck is used at a race
track in the stable area where considerable hay and horse bedding
is constantly flying around.
What to do? MACS Member Caroline Acebedo of Marks Air
tells us, "The customer had no idea that there was a cabin air filter
in the truck. The way this International is designed, when the A/C
is turned off, the outside air door opens. Due to this customer's
environment, we chose to replace the filter, clean the evaporator
and case, and then unplug the outside air motor to prevent the
horse bedding material from dropping down into the evaporator
case again." ❆
