I will be upfront and admit that I don't know much about Central Air.
I have a HVAC guy wanting to put in the following system in my house
2 5 Ton systems with ADP BCRMC6460S3N4 air handlers with Fedders 13
Seer 5 ton condensors. He tells me that the Air handler is a 10 SEER
unit but has a expansion valve built into it that makes it 13 SEER. Is
this true? He tells me that this Air Handler is better than the First
Company air handlers others are proposing. Is that true? He also
tells me that Fedders uses Copeland compressors and therefore it is
very similar to the high priced brands. All the listings I have seen
on this forum state otherwise. What is the opinion of this forum with
regards to Fedders?
He also wants to put in a single return each on the first and second
floor. The other opinions I have gotten say that I need to get
multiple returns on both floors for efficiency. He tells me that the
it is a nightmare to balance the system with multiple returns and he
won't do it, no matter what. What is the truth here with respect to
single return vs. multiple?
Please help as I need to make a decision soon.
