A pellet stove set to a thermostat is the most efficient way to heat a unit that guests can actually understand.

(Linens, service fees, keypad, thermostat, noise monitor, etc.)Anything helps!

I go in to check and turn the thermostat up.

LOLMind you, I automated everything: Keyless Entry with Z-Wave system, Thermostat, Cameras, etc.

My HVAC guy is charging me for the following: adding a 70K BTU gas furnace, a 2.5 ton AC condenser, 40 gal water heater, all ductwork, registers, gas piping, thermostat, permit drawings: $11kI don't know if this is a normal price, but it's the one we decided to go with.

Ideas I had:• Nest automates thermostats and one day in the near future is a good implementation in B rentals• HVAC or dishwasher breaks and technology can alert you• Technology good for B and A class• Class B rentals are having Amazon lockers and these Nest thermostats• Know your avatar• At one time backsplash in kitchens was unheard of and now its a cheap fix• What is standard in the market?

I can have a second thermostat installed so that the landlord and the tenant can control their own preferred temperature.

If the area is "nicer" (and it sounds like it based on the 400 K values and rent levels) the tenants probably just want to hit that thermostat and get state of the art AC, cool through the whole house.  

The Tenants could be cutting the thermostat down when there not there and turning it up more than a couple degrees at a time.

We buy units that have digital thermostats, and have sufficient cooling capacity for the space, so they work well.
