Get a remote thermostat so people have limitations on how low they can set it.

Smart lock (or lockboxes), smart thermostat, a locked storage room full of cleaning supplies and extra linens, and you'd be amazed at how your margins will increase, if that's what you want to do.Best of luck!

Has anyone here installed a Nest thermostat before?  

Hello all,Yesterday I installed my first Wifi enabled thermostat and I'm in love.

The A/C people came out ( I had authorized them to do the seasonal cleaning and maintenance as well at the same time).I got the bill for the regular maintenance..but on the bill was a charge for 20.00 for battery replacement in the thermostat.

I've had multiple professional people look at it and they say it's working but if possible I can install a separate thermostat in each unit to help regulate the heat per unit. 

I am not planning on replacing it until it goes, all asbestos gone, replaced iwht expensive fg pipe insulation and I made a 1" ins. blanket for the boiler. uses around 2k gallons per year (less actually, 1,734 over past year) -- ONE thermostat, which allows for one cycle per hour and is programmable - no one touches it and it keeps the building pretty comfy--no complaints except 3rd floor when system needs to have H20 added, or bled.

Either on purpose, by pulling the lever on the vent, or accidentally, by blocking them with furniture, rugs, etc.Some people think that if the house is too cool, the way to fix it is to not touch the thermostat and close some vents.I use the pleated paper filters that cost about $1.50 each, but I do have a newer system at my rent house - the furnace and A/C are both about 3 years old.

This is with each area having a separate thermostat.

Some inspectors will look at a furnace, for example, and just look for visual damage, turn the thermostat to make sure it's heating, etc., but that's about it.
