We have a goodman heat pump. It is electric heat, we are in Ohio so its getting in the low 50s. well the first stage kicks on the less then a minute the second stage will kick on. Should the 1st stage run longer. We the heat set at 68. it only drop to like 66 or so then kicks back on. We have tried 2 thermostats. and it does the same. I could understand if we are trying to go to 80. The system is a year and a half old.

Heat pump T-stat will kick in 2nd stage after the second degree drop from set point. So set a 68, 67 1st stage kicks in and at 66 2nd stage kicks in(depends on T-stat). Heat pumps are made to maintain temperature not to make wide changes in temperature( in the heating mode). If your not raising temperature from 66 to 68 but outside temperature is making house drop from 68 to 66 it may be dirty outside coil, dirty filter or low of freon.

So what good is the 1st stage? I thought if it was below a certain temp outside then 2nd would kick in. Lat year the 1st stage would run till it finally got below 38 outside then 2nd would kick in. But now if its 50 outside. To me Goodman is total junk. I called customer service and they said they don't help customers. No one around here seems to have a clue.
No, why would they have but in a 2 1/2 ton handler and a 2 ton heat pump? Should of bought a something better. But, homeshield would only allow some much for this.

There should be nothing wrong with your equipment. A 2 ton heat pump and 2.5 ton air handler are how you get a higher SEER value and more efficiency. A heatpump, your 1st stage, is considered the most efficient and will always come on first at your set point of 68 degrees. Now possibly as the blower begins circulating air, a colder pocket of house air is causing the thermostat to drop lower than 68 and thus triggering your 2nd stage heating. You can set the temperature drop you want before the 2nd stage comes on so check your thermostat setting. Also if it's really windy and 40 outside, on a call for heat, the heat pump will run first but may not be able to keep up with the heat loss due to the wind. That's when the 2nd stage will help out (inside temp drops to 66, assuming a 2 degree differential between stages).
As the outdoor air becomes colder you'll pass the temperature (balance point) where the heat pump will not come on at all because it can't do any good. That's when you're 2nd stage heat effectively becomes 1st stage heat.
