Quotes for a new A/C system
Hello. I'm hoping to get a sanity check on some quotes I have gotten for replacing my heating and air conditioning.
I live in a Los Angeles suburb, and currently have a 1970's era 5 ton Lennox heating and air.
I've gotten quotes from a few dealers which include the furnace, condenser, coils, and also replacement for the old ducting and new return. Basically a whole new 4 ton setup including moving the furnace into the attic with any electrical and plumbing work needed.
Lennox XC14, Lennox SL280V, not sure about the coils, HC10 filtering system Honeywell prestige thermostat. $13850 ($3000 of which is the new ducts and registers)
Second one is
Carrier Gas Furnace Model 58PHX090116
Carrier Two Speed Outdoor A/C Unit Model 24ACB748A003
ADP Horizontal Cooling Coil Model C48H210D576
Last one is American Standard
16-SEER/ 13-EER system 1-stage condenser, coil, 2-stage Variable speed furnace.
Honeywell 6000 Wi-Fi thermostat
Comparing these with some of the other quotes I see on this web site is very hard. These quotes are much much larger than the ones I see here, but at the same time I think there is less work involved when compared to my quote.
I would appreciate any advice that could steer me to a better decision.
