Since Summer is upon us, the last week most people have been using their A/C. With that being the case, I thought it would be a good idea to start a thread to talk air conditioning!
I'll start with a few questions:
1) With the A/C on, does the fan speed change anything with regards to energy usage (other than the extra energy for the fan)? In other words, does the A/C work harder with a higher fan speed or does the A/C only have off/on capabilities?
2) A lot of times, I cycle the A/C on and off because when I turn it off, I still get cold air for a little while. I'm wondering, is this cold air residual from the system components, or does the A/C stay on for a certain amount of time after turning the button off?
3) How much slower would one need to drive to match the equivalent FE of A/C on vs. off? For example, if one drives 65 with no A/C, would driving 60 with A/C on be the equivalent FE wise? I know this will vary by car, but I figured a rough estimate would suffice for most people.
Let's talk A/C!!!
