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

I have a Buderus SST300-80 indirect water heater and notice

Good morning,I have a Buderus SST300-80 indirect water heater and notice that during the summer months when we have higher than normal humidity, there is water that leaks out of the bottom of the unit. The heater is only 4 years old and this doesn't occur during the other months of the year. Has anyone ever experienced anything like this and what would cause this? I can send a picture of this if you let me know to what email address.Thank you,Vin
