I just bought this home in Los Angeles that is 2044 sq-ft.
It is consider to be a tri-level with the family room at bottom and the top floor has the 3 bedrooms. Windows exists facing all directions except the south. it has a an old force air furnace located in the hallway which I want to replace and move to the attic.
I had 5 bids but I took out the lowest and the highest. I'm working for one contractor to submit his bid.
He took the time to measure each room and answered my questions. He mentionned federal tax credit for the higher SEER units.
American Standard Allegiance 3.5 ton A/C 13 SEER
80,000 BTU 80 AFUE furnace
He gave several upgrade options but emphasized that upgrading to 2 stage variable speed furnance would be recommended. He also said that 2 intake/return vents would best serve my house.
He surveyed each room but did not take any measurements.
Trane A/C 5 ton 4TTR4060A 1000A (14 SEER)
Trane Coil HD206600245B260300
Furnace T4D1D1204760 (80% AFUE)
He said that one return air filter grille 20x25 would be good enough because it will set in the hallway near the stairs which does not have any obstructions.
I mentionned the variable speed and he said it was not necessary unless you do zoning because the vs is trigger by static air pressure?
He emphasized that he would recommend just what is needed and does not like to recommend unnecessary options.
I don't have his estimate yet but he deals with York and recommends the Affinty line with furnance 80% AFUE with VS and 5 ton A/C 2 2 stage hybrid?
He also mentionned York rebates.
So far contractor 2 is cheaper but doesn't include the VS for the furnace but includes the Accuclean.
So what do you guys think? A total 3 of them recommend 5 ton, would that sound right?
How about the intake/return?
What the Electronic air cleaner system?
