New Trane system rumbles on startup/shutdown, and other issues

I had a new Trane system installed recently in my home. It is an xl14iheat pump and xv90 gas furnace. When the heat turns on, there is a 1second rumble/vibration somewhere in the furnace, and about a 2 secondrumble when the system shuts down. I've had the installer out 3 timesand they can never fix it. Seems like they make it quieter, but in acouple days it's back. The furnace is in the garage and backs to oneof the walls of our primary living area, so it is rather annoying tohear the thing rumble on and off. Has anyone else had similar issues?I don't want to pay > $10K for this new system, which is supposed to beso quiet I won't even know it's on (yeah, right).Also, I have some issues with the system heating the house in themorning. I have a 2500 sq ft home, 2 floors. The thermostat isupstairs. On a typical morning, 45 degrees outside, house is at around65. At 7am I have it programmed to heat to 70. I have the adaptiveintelligence thing turned off. First thing it does is start up theheat pump. After a minute or so it switches over to gas, then itcycles back and forth between heat pump/gas, and it ends up takingabout 2 hours or longer to heat the house up 5 degrees to 70. I wentinto the programming of the thermostat and changed one option to makethe recovery ramp more aggressive, and it seemed to help some, keepingthe gas heat on longer, but it still cycles back and forth. I wouldfigure the system would be smart enough to immediately go to gas, rampup quickly as possible to 70, then switch to heat pump for the rest..Is that too much to ask for? Is there any way I can program thisbetter?One more thing, how do I know if the second stage heat is actuallyworking? Should I hear the furnace speed up or feel more air comingout of the registers? Does second stage heat system work with both theheat pump and gas, or just when the gas is running?Thanks for any helpJason

After searching the web, it appears that my thermostat is the honeywell vision pro, with a Trane name. So why did they choose to use the fossil fuel kit when the thermostat is fully capable of doing the job?

That thermostat has not been out all that long. Just a few short years back we HAD to use the fossil fuel kit. Why did they choose to use the fossil fuel kit AND the Vision Pro/Trane stat? Your guess is as good as mine. My guess would be that they dont seem to have a clue. Bubba

You can't control both stages of the gas furnace with that stat with a heat pump as primary and furnace as auxillary heat. X2 is the only source from the stat for aux heat, therefore, W1 and W2 must be jumpered together at the furnace.
