My husband insists on always using the air conditioning in our 1997 Ford Explorer instead of using the various vents. Even if he wants it warm, he simply turns up the thermostat, but leaves the setting on A/C.
It is my belief that A/C is warranted when it is hot out, but if it is cool outside and simply stuffy in the vehicle, one of the ventilation settings is more appropriate.
What is your opinion? Is using the A/C all the time hard on a vehicle? What are the ramifications, if any.
For one thing, if it is less than 40 degrees outside, the a/c unit is not operating, so his setting is nothing more than using the vents (assuming he does not have it in recirculate mode, in which case, all he is doing is moving the inside air around).
Running the a/c does put extra strain on the engine, but not more than it was designed to handle. In addition, it does use extra fuel. If you were to convince your husband to shut it off, you will notice about 2 mpg better fuel economy.
