Picture the air-source layout
There is equipment outdoors and equipment indoors, connected as specified for the system. A central design uses the home's air distribution. A ductless design uses indoor units serving planned rooms or areas.
The important choice is how the system serves your home. We recommend first deciding which rooms need heating and cooling and what existing equipment you want to retain. Then have a qualified designer compare the suitable air-source options.
Ask where the outdoor and indoor units would go, how the connections and drainage would be routed, and what electrical work is required. No ground loop does not mean no installation work or no changes to the property.
Ground-source is a separate assessment
If you specifically want to explore ground-source equipment, seek a qualified ground-source designer and installer for the loop, site feasibility, and full project. Keep that assessment distinct from an air-source proposal.
For an air-source choice, ask for exact models, local cold-weather performance, home load calculations, equipment matching, and any backup role. The word “heat pump” alone does not tell you what those details will be.
Compare the complete home plan
A proposal should identify what the system will heat and cool, what remains in service, and who owns separate electrical or air-distribution work. Ask how room comfort will be checked after installation and what care you will need to do.
Do not let the buried-pipe misconception stop a useful air-source assessment. Also do not buy solely because that project sounds easier. Its fit depends on the home, equipment, and installation.
Your next action is to ask for an air-source layout for your home. You should be able to see the unit locations and understand the work involved before deciding whether to proceed.
