My daughter's rented house is heated/cooled by a heat pump (so all electric).
The other day she said it was putting out cold air (they've been setting it back to 61*, normal is 66* after a $400 bill last year).
Outdoor temp was likely 19* at the time.
Repair guy (an electrician son-in-law said) came out today and he said the guy said "both pipes were cold" (outdoor temp today was a lucky 50*). Son thinks the guy did something but not sure what.
Rental agent said their system is fine, to set it to 69* and not set it back and it won't need Aux heat.
My questions:
1. what is a reasonable set back to save some money (if there is one)?
2. How warm would the tubing be at the air handler? Would that temp change as outdoor temp drops?
Other advice/thoughts welcomed.
