New Heat Pump Installation, Fresh Air Vent Needed? EM. Heat

Multiple Questions:
1. Hi, I just replaced my coleman furnace with a 13 seer 3 ton Westinghouse Heat Pump and air mover with 410a refrigerent. During installation the techs. didn't hook up my fresh air vent hose. The hose is a large flexable tube hanging from the ceiling that was used with the old coleman furnace. I asked about it and was told it was not needed with a heat pump.
My concern even though they taped the vent closed inside. Will this cause moisture build up inside the roof or any other problems. The vent is still open on the roof. Also, The air is very dry now and I'm having problems with sinus at night when sleeping. Could this be because the vent was closed off inside.
2. Also, I was testing the em. heat. They was to install 10 kw heat inside the indoor furnace unit. When testing this the em. heat would cycle on and off but didn't raise temp two degrees after 2 hours. The fan continues to run between em heat cycles. I think its cooling it back down before the em. heat cycles back on. Is this normal... ? Could it be a programing/wiring problem or was the 10kw heat kit not installed or not installed properly. My old furnace would heat better than this.
3. Was told this unit would run more than my old coleman furnace. Didn't understand why? Shouldn't it run less. Was told that honeywell digital thermostat was very sensative to 1/2 degree and would cause unit to run more. Worried that instead of decreasing electric bill will have higher electric bill. ? Should the heat pump run more? Could this be a installation issue?
