:thumbup: Two weeks ago a friend told me her A/C was slowly dying (dieing?) ... whatever ... was cooling less and less each day. Here in southern NC, it's been HOT HOT HOT, so this was pretty bad news. Someone told her to check the battery on her thermostat? HUH? Who knew thermostats had batteries? But she pulled it off the wall, replaced the battery, and it works fine now.
So Tuesday I came home from work and my house was 85 degrees and the A/C wasn't running at ALL. After my moment of panic and dismay thinking about the $ for the service call, I pulled the themostat off the wall and, sure 'nuff, there were two AA batteries in it. I pulled some out of the Swiffer and stuck them in the thermostate and ... voila ... free fix!!
Neither of us had ever heard of this, and when I told my parents, they hadn't either. Maybe this is something the repair guys never tell us ... just come in and change the battery and charge us a small fortune to "fix" the A/C unit??
In any event, I've been passing this tip on to everybody. Sure saved me some bucks, and I hope you can do the same some time.
