Central heat and AC?
Or baseboard heat with AC?
Or no AC?
Upgraded my 20 year old oil burner hot water forced air with a heat pump... Last October.
Saved myself at least $500 a month from oil in the winter..
Still use it for hot water and as backup emergency heating...
And saving me on AC in the summer
Daikin One with variable speed inverter and blower... Highly recommend.
2zones were from before but still works the same... Single blower does both...
Feel free to ask anything
