We have 2 Lennox roof top heat pump units in our office building. They
are a T-Class unit and a CHP-Class unit,

We like to clean or replace the air filters since it has been over a
year since they were installed.
Does anyone have experience with these 2 models of HVAC and know how to
gain access to the filters?
Thanks
