It's just the website software making the best guess the programmer knew how to make based on the information available to it via the web.After all, it does not NOT say "Zappraisal".It says, "Zestimate": Zilllow estimate.This is probably as good a definition of "estimate" as any ...

Wifi thermostats are hard wired to the HVAC controls.

Maybe you should consider one of the thermostats that you can monitor via an app on your phone or at least have a programmable one installed so you know its getting turned down when nobody is at the property.

It's definitely going to be cheaper and faster than hiring a programmer to do the work for you but I always wonder about the quality and the freshness of any data that I receive from 3rd party sources.  

Hello,I recently closed on a triplex and the apartments feels very chilly in winter weather proofing with a plastic cover sealing the windows  mitigated the issue little bit but I would like to get to the root of cause since even when thermostat is set at 80 it feels chilly,especially my lower two units are very cold despite a centralized ac system.Unfortunately I couldn't catch this during inspections since it was warmer weather around that time.I am now dealing with higher utility bills who are some professionals that I can get in touch with for solid weather proofing ?

I haven't found a fiverr zoho programmer though.Gosh, I wish someone could remember the guru who promoted a pre programmed zoho.

If the furnaces already have thermostats then they will control the AC as well.Typically the condenser just sits outside on a slab.  

The thermostat being set low could be an indication that the heat was not on.  

With 10% down my payment would be around 1500.00This house has a Goodman ac 14 ser and 1 thermostat situated in upper floor to cool both floors.

I work as a Database programmer/Business Intelligence guy for a day job, but I am hoping to make the move to full time REI over time.
