If you have both, when do you switch from heat to A/C in your home?
The last 5 days here have been in the 80+ degree range, which is 15-25 degrees warmer than normal per historical average. The next several days are predicted to be in the historical average range. My wife is growling about turning the A/C on, but I'm holding out so far (I'm comfortable as is). Do you wait until a certain mm/dd or do you go according to conditions? When do you switch?
