I had a service call once in January. Entire K-Mart was 50 degrees.
Head up to the roof access and notice that EVERY UNIT ( 19 ) is in free cool.
Call the 1800-novar number and get some guy NOT in Houston, give him the store number and ask him what temperature does he think it is in Houston right now.
A couple of taps and he tells me 72 with low humidity......
Ahem....I tell him it's 44 degrees and rainy..
A couple of taps and all 19 units one by one go into heat. Pretty cool but still stupid.
We dont need economizers in Houston.
