New HVAC System
Comments (1)Excellent system. Qualifies for Fed Tax Credit AHRI Match-see below 5775563 Active Systems XL18I TRANE 4TWX8036A1 *AM7A0C42H31 1170 935 37400 13.00 18.00 32400 9.50 21200 1 HRCU-A-CB 251 612 Yes Change thermostat to Trane's 803 or save yourself a few bux with identical HW Mdl 8321. I prefer Trane's Perfect Fit media cabinet. Cost difference should be inconsequential. To correct your hot spot, you need more airflow to those areas that are warm in summer. Discuss with dealer and ask for suggestions to improve. Since you are going up in size, your ductwork system needs a thorough evaluation to make certain it can handle the additional CFMs. How many returns do you have and location? You would be able to save some money with a single stage system like XR15. You might want to ask about that for comparison purposes. IMO...See Morecarrier hvac or trane hvac
Comments (5)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...See MoreNew HVAC System - Stage 1 not coming on - Stage 2 Only
Comments (25)Solution to this problem. When you update your system from single stage to 2 stage, you must have C wire from outside unit. My old single stage system came with 3 wires from outside unit to indoor (blower) and Indoor unit to thermostat had 5 wires. I solve this problem with new wiring the whole house. I install 4 wires from outside unit to indoor (blower) (red(Rh), blue(C), yellow(Y1), purple (Y2) (mine had a purple)); Indoor unit to thermostat install 7 wires, which following below. red (Rh) blue (C) yellow Y1 Cooling stage-1 Gray Y2 (Purple Y2) Cooling stage-2 Green (Fan) white (W1) Heating stage-1 brown (w2) Heating stage-2 If you don't want to rewire, I recommend to get CTK04 thermostat, which will be fine with your old wiring....See MoreHVAC: House Design - HVAC input please
Comments (6)I suggest separate systems for the first and second floor. That is the best way to have even temperatures on each floor. It costs more up front, but you potentially have lower operating costs. You could zone the loft off the second floor system. However if you are going to be working 10 hours days with multiple pieces of equipment generating heat then spend the money on a mini split....See Moreaprilmack
