Hi,
I still have some homework to do, but the symptom is low air flow. As of the end of the heating season air flow was good. I cleaned the air filter as I usually do 4 times a year. (allergy pure cleanable) Now the cooling season and the cooling/air flow seems less.
I have a nordyne (tappen oil fired furnace with a/c.) regular pcs motor on the blower. 3 tons (i think) 5 years old. I cleaned the leaves out of the condenser and hosed off the coils. I have two supply grates off, one upstairs and one downstairs for painting.
The house set up is two story with an air manifold in the attic. It supplies all upstairs and 2 downstairs supplies vents, both of the removed vents are off of this manifold.
A nest thermostat was installed during the heating season and works well.
Tomorrow am when it is cooler I will check out the attic to make sure the manifold is not compromised. If memory serves me correctly the blower motor is 2 speed, but not sure if heat or a/c is high speed. If a/c is high speed, it maybe that the nest is calling for low speed. maybe?? I will check out attic and blower speed rating and post back tomorrow.
If anyone has any thoughts, please post.
Thanks,
Bernie
