Look for a company who does energy audits in your community. They can help you assess your situation, how efficiently your components are operating, and make recommendations on how to improve it.
Isn't it better to keep all air conditioners on all the time as with our open floor plans one a/c will have to work overtime if others are off and it could effect performance? Do a/c units need hibernation breaks?
No. In fact the harshest time on an A/C unit is when it first cuts on and the first few minutes of running. It doesn't even get to its maximum potential until about 10 - 15 minutes after coming on.
You have over 2500 posts and are a senior member. I would have expected a helpful response from you. And yes I do work for free. Its called voluntary work. But that is not the topic under discussion.
BTW, I never implied free. There are many companies that provide free estimates. I just need recommendation from people on forum who have had the services done and what they think of the services.
if you think the thermostat is acting up, then switch the upstairs one and downstairs one, then see if the downstairs start exhibiting the same symptom, while observing if the upstairs exhibits proper behavior.
that will help you rule out the thermostat and save you some bucks.
Hot air rises, and if you have a home with a 2 story open area, that means the air is constantly moving from low to high. Set your upstairs thermostat to 1-2 degrees higher than the downstairs unit, like 78 upstairs and 76/77 downstairs. That will help equal the running time of both units and give the upstairs unit a bit of help in maintaining temperature.
Our house is almost 3700 sq ft and this has worked well for us.
I tried that where I set the downstairs to 76 and the upper to 78 but that did not seem to help that much. As soon as the temperature changed in the room with the t-stat on 2nd floor the AC would act up.
