Goodman heating system -gmt1155b is not providing enough heat.
This heating system must have two heating stages. It is only heating ,and giving out warm air .It's not going into the higher heating stage. filter is clean ,returns are cleared. What can I do to get it hotter?

If you are using a single stage with just a W connection not a W1 and W2 then it may be wired to the W1 connection on the furnace contro board. in that case it will only run in first stage. the easiest thing you can do is run a small piece of wire between W1 and W2 on the furnace control board. if you dont have a W1 and W2 connection on the board then its not 2stage, if you have an extra wire at the stat you can get a 2stage stat and wire W1 and W2 individually.

This link gives a lot of info but not what you are looking for I believe. Most 2 stage equipment will have a Y1 and Y2 at the terminal block inside the air handler. And a two stage cool, two stage heat would work for yours, it appears to be a heat pump. Now at the outdoor unit, if it is 2 stage, you should also see Y1/Y2 terminals. As far as a filter media? Hard to say.
A heat pump on the optimal heating day (about 50 degrees ambient) will only deliver approximately 85 degree air as compared to 125 degree air from a fossil fueled furnace. The colder the outdoor air is the less heat there is available to be transferred to the living space. At 30 degrees, the heat transfer capability is getting close to negligible meaning the run cycles will be approaching continuous and eventually as the heat pump along cannot maintain setpoint, the outdoor stat or stats will bring on auxilliary heat in the air handler.
If your ambient temp is below the 'balance point' of the heat pump, the house temp will drop a little lower and most times energize the heat strips through the outdoor t-stat. Your outdoor stat could be set too low for the heat pump to carry the structure all the way down to the balance point so when you turn it off and back on, the lower indoor temp automatically brings on the heat pump plus a heat strip or two, thus the warmer air. Second stage on the stat satisfies due to the heat strip, drops them out of the circuit and the heat pump is left running on first stage heat delivering the perceived cold air.
Your outdoor stat could also be not functioning correctly and not allowing the heaters to come on until the system is turned back on reestablishing the two stage call for heat.
Tons of possibilities and not enough room to list....
If I remember correctly, there are dip switches on that control board that can be set individually. It is possible that it is just a setup issue. The switch positions should be explained in the installation instructions. I know that some Goodman and Amana two stage furnaces can be controlled by a single stage thermostat, but the dip switches have to be set properly. If the switches are set correctly the furnace will run in low stage heat for approximately 5 minutes and if the thermostat hasn't satisfied yet, it will kick in to high stage heat. I hope this points you in the right direction!

I'm assuuming you are talking about your furnace or 2nd. stage heat, when you say piggyback system. Yes you can go to your thermostat or furnace and disconnect just the 2nd. stage heat wire(see furnace wiring diagram), this will not allow the heat to come on in the furnace but it will still allow the indoor blower to run and the heat pump.
the thermostat sub base has a place to connect a wire usually white to energize the heat strips when you push the stat way hotter than the house temp. that is why the strips come on in normal heat. it also has a terminal that is only energized in emergency heat and it also should have a wire connected to it so that terminal can supply power to the strips when the stat is switched into emerg heat . you can identify the terminal from the wiring diagram and if need be jumper w2 wire over to the aux terminal and it will work. they both go back into the airhandler and power the same strips. w2..................................................................................................w2 in airhandler to strips or w2...jumper to aux......................................................................................................................w2 in airhandler to strips.
