Agreed Hanr3 ! DEFINATELY insist that they install a HARDWIRED smoke AND CO2 detector; many states and municipalities REQUIRE them now in all new construction. For the cost ($300.00 tops) it`s CHEAP `life insurance`, same as wearing a seat belt or life preserver...chances are when you tell your Insurance provider that you`re upgrading your HVAC and installing the hard wired smoke and CO2 detectors you should qualify for a rate reduction! It may not be huge, but your savings on your heating and cooling WILL be !
