I have a 3 family that I pay the heat...it's 3 stories and each floor is it's own apartment...we call them 3 deckers here in Boston...I just bought the house 2 months ago and now it's heat season...looking for suggestions as to which floor I should put the thermostat in...I'm debating on either the 2nd or 1st...I have had conflicting advice by 2 contractors...anyone here have this issue?..

I looked at the thermostat and it was set at 78.

We have found the best way to keep things running smoothly is to have a designated "Den Mother" in the house - in our case, my sister-n-law.4) You will be carrying all the utilities; as such, it is in your best interest to invest in programmable thermostats (with a lock-out limits on max and min temperature settings); low-flow fixtures and LED lighting.  

I had to pay to replace a thermostat while living in an apt and a lot of maintenance items are the tenants responsibility.

All necessary gas piping, duct work, registers, flue piping, thermostats, 5" aluminum chimney liner and supports are included.

We changed the thermostats out to ones that limit the set points but separating the heat was too much right now.

This would of course require 3 base things:  1) efficient utilities- a natural gas hookup in this case, 2) a well insulated house (sometimes challenging in the multi units in New England), and 3) implementation of a landlord thermostat to control the heat and regulate it to a range 65- 71. 

Because he made a note of tweaking the thermostat config while he was troubleshooting everything else, the warranty company denied my claim because the "system was configured incorrectly" which voided the warranty for the entire heating system.

I have been thinking of installing nest thermostats in each unit.

I would walk through, and something small (like say a thermostat) would be fixed or updated.
