First, I'm gonna tease y'all with a little pic where this air handler is installed. Living room closet at the top of the stairs.
Things I like about this install: 1" fitler base, float switch, new disconnect, high voltage whip, and platform.
System is 3.5 tons and the airflow was tested at .52"w.c. delivering 1357 CFM. No supply ducts were changed on this job.
New t-stat. Customer opted for non-progamable version.
