good deal or overkill for AC and furnace
I have received 2 bids, and want to make sure i am not being taken advantage of. I am in Dallas, TX, in 1 story home, with roughly 2300 sq ft of livable space, and insulated attic.
110000BTU Infinity 80 4-way variable speed Carrier gas furnace
5 ton 17 SEER Performance Series Carrier - 2 stage
Infinity programmable therm
surge protector (not sure if this is needed)
5 ton evap coil
Duct Mount smoke detector
Refrigerant locking caps
flush and pressure check line set
total = $11900, including small discount
other bid (doesn't go into as much detail as first one):
4 ton XC16 AC - Lennox
16 Merv filtration
new 7/8" lineset (add $800)
dampers for vents
total = $12500
1. if the add-ons in the first bid (smoke detectors, co monitor) are necessary.
2. is one system better than other.
3. i recognize that 1 is for a 5 ton vs 4 ton unit, but is the quality different?
ideas and thoughts are always welcome
