The old dinosaur that has been heating my house for the last 26 years has finally bitten the dust.
I have narrowed the search for a new furnace to two installers. Both are highly regarded contractors and "Premier Installers" for their respective systems. The prices quoted by the two contractors are virtually the same. So it seems to come down to the equipment.
The house is around 1200 square feet, located in northwest Oregon, and was built in 1981. The existing furnace is rated at 60,000 BTU.
Proposal from Contractor A:
A Manual J heat loss calculation was run and "about 60,000 BTU" is required. I have requested a printed output for review.
The proposed system consists of the following:
Lennox G61V high efficiency furnace, 70,000 BTU rating.
"Healthy Climate" MERV 10 filter. The MERV 16 was presented as an alternate but costs a bit more.
Honeywell VisionPRO 8000 series thermostat.
A thorough duct cleaning will also be performed.
Proposal from Contractor B:
No heat loss calcs were performed. The recommended size was based on experience and the existing furnace size.
Proposed system consists of the following:
Trane XV95 high efficiency furnace, 60,000 BTU rating.
Honeywell F300 electronic air cleaner.
Trane XL802 thermostat.
Duct cleaning is also included.
Any thoughts, opinions, sneers of derision regarding these proposals? I would be especially interested in furnace sizing, and the media filter versus the electronic filter.
