Jt Some questions please. What is your location? What size home living area? What size furnace and eff are you replacing? What size AC are you replacing? I would like to know the exact mdl number evap coil for each quote. What thermostat is proposed for the Carrier quote? That is a big difference between the 96% eff Carrier furnace and the 80% eff Trane furnace-both 60 K input. That would be about 56 KBTUs output on the Carrier and about 48 KBTUs on the Trane. Not insignificant. I don't care for some shortcuts that homeowners make particularly on reusing linesets and using existing thermostats that shortchange a nice furnace's operational capability. Post back with the info requested. IMO

it is a 1 1/2 story, upstairs open to landing and loft overlooking d/s living area. Makes for 20ft ceiling in living area. Quote 1 did say he would do a load test before starting. I am about to call quote 3 with questions.Included with quote 3 system to include : recovery of freon, dipose old equipment,float switch, programmable thermostat, auxiliary drain pan, high & low voltage conduit at outdoor unit, city permits & inspections, adapt to existing ducts, new gas cut-off and flex connector, all new vent pipe. I was dissappointed that this model I would have to pay for 10 yr labor whereas Infinity series comes with 10 yr l&p. But he said measurement wise an infinity wouldn't fit in attic. Is the media box filter what we change out? If so ours is 24x36x1, not the easiest to find and none of the contractors have mentioned this.

This is my first post on TGW. I will be the first to say that my experience with Trane is very subjective and anecdotal, but the following experience is mine nonetheless. We bought an existing single story 2280 sq. ft. home in Auburn, AL in May of 2012 (15 months ago). One thing that sold me on the home was the presence of a Trane 14SEER HP with variable speed blower installed in 2007. In June, one month after purchasing the home, we had to call the local Trane company to come out for a non-cooling situation. By August, we had replaced (due to actual failures, not just "failing") the compressor, the blower motor, the blower motor circuit board. All but the circuit board were under a part warranty. However, with labor, freon recharging, etc. We shelled out over $2600 in 2012 alone. In March of 2013 we had to replace a startup capacitor, not under warranty, for $400.00. All told, since June of 2012 (this post is made in early Sep 2013) we have spent well above $3,000.00 on this Trane HVAC system. In that time, I have learned (from an independent, well respected local HVAC guy) that our system is woefully OVERsized. We have a 5 ton unit in a space that, I believe, calls for a 3.5 ton unit. We have $500 power bills in the summer months. In general, I think Trane makes a great product like BMW makes a great car. You should just know what you are getting into. The most urgent comment I would make to anyone buying a Trane is to DEFINITELY get the maximum parts and labor warranty you can get and make sure it's transferrable to a new seller.
