In the High Desert of SoCal. 1500 sq. ft ranch. Dry heat but not uncommon to go 100 degrees plus for weeks on end. I am looking at replacing a 19 year old Carrier split system. The furnace/blower is inside the house in a hallway closet. The outside unit sits under our Master Bedroom window. So sound is somewhat of a concern with both parts. I like & trust our local Carrier dealer. Here are the various options he has given me:
1) Infinity 18 AC + Infinity 96 Furnace
2) Infinity 18 AC + Inifinity 80 Furnace
3) Performance 14 AC + Comfort 80 Furnace
With about a $1500 difference (after rebates) betwen 1& 3.
Wondering what you insiders see as any practical downsides to going #3 vs # 1 or #2.
I rarely even use heat - maybe a few hours in the AM during Dec-Jan-Feb. Mainly want an efficient quiet AC.
I figure either Infinity or the Performance set-up will be an improvement over the current rig - just having a hard time figuring out if the extra $1500 would be well spent going top-of-the line...
Any input would be greatly appreciated...
