I'm trying to purge my heating system but no water is coming
I'm trying to purge my heating system but no water is coming out of the hose. I tried each zone separately. Baseboards are not getting hot either. The circulator pump was put in last fall and seems to be switching on. Furnace is 2 years old. Zone valves and circulator pump are 1 year old. I also have a Spiro air eliminator on the system. Every year I have air in the lines so I tried to purge them this year, but I'm not even seeing water coming out of the hose. What could this mean?

I have purchased a multi level house on stilts in a rock
I have purchased a multi level house on stilts in a rock quarry, a stream runs under the house. The current HVAC system has the ductwork under the house, exposed ti elements. Its is 10 years old. We live in Western NC. The current system cannot heat or cool the house properly. Should we install mini splits? or a new unit ( gas) that we put IN the house. Currently the HVAC is a heat pump located outside. Help?JA: Did you double-check the thermostat's settings? And what about the filters?Customer: Yes. we used thermoters as well as the thermostat. They had no filters installed.JA: Do you plan on doing the work yourself?Customer: we could probably do the mini splits ourselves but not the HVAC. The great room is large with cathedral ceilings. Techs here said the big minisplit would be noisy. Do you think so?JA: Anything else we should know to help you best?Customer: House is 3000 sq ft. Lots of high ceilings. Next to granite rock, so cold in winter. Lots of humitidy due to water coming down rocks. Sometimes lots, sometimes little
