OK i know each install is different but what are some pro's and cons of each?
existing hvac is 9yrs old in a 9yr old house. 4500sf like this:
hydro air 2 handlers
2 outdoor splits for ac only
1) replace existing ac only splits with geothermal splits and air handlers.
2) add geo water to water, use a storage tank and run hydro air at 110. i see this around and don't understand the benefits.
3) replace basement/1st floor unit with geo to air and run a geo split for the second floor.
not looking to diy this just make some decisions about whats best way to go.
thanks for your time.
