Me and my mom and dad moved to a older house since we have moved in we have had health problems
You need to have your new home inspected for excess dust, mold, CO, CO2 and any other pathogens. Most of these items would have been found with a good home inspection. Also, the heating system, exhaust vents, chimneys, any air filters, water lines and sewers need to be inspected. Areas of excess humidity and wet spots need to be addressed. There may be other problems but these should be looked at first.
