How best to heat an Arizona two-story home?
Asked by Ted
We have a 2800 sq ft home with dual thermostats. I have the upstairs turned 'off' and use only the downstairs to set temp. There are 2 cooling units, 1 full size, 1 half size. I honestly don't know what the heating is as it is in the attic. The upstairs stays very comfortable with this method and a small space heater in the open bathroom when showering. Is there a reason I should be using both thermostats, up and down? I keep the temp at 62 -65, turning it no higher than 68 if it is damp. Thank you for your reply.
Answer this question
If you are comfortable with this system, there is no reason to change it.
- I would recommend that you don't turn off the upstairs thermostat, but set it at a lower temperature, say 60.
- That way if you have a really cold night and your downstairs unit can not keep the house warm, the upstairs unit will kick in.
I am guessing that in the summer you run both units for cooling.
One thing to check is to make sure your units are not oversized.
- Oversized units waste energy and money and don't keep you as comfortable.
