Hey everyone! This is my first post here. I joined up because I have been searching the internet to see if anyone else is experiencing what I am experiencing, and I can't seem to find anyone describing the same thing. We bought a 2018 FFH a couple of months ago, and one of my biggest gripes with it is the lag in the a/c after I turn the car on. It takes something like 15-20 seconds for the air to start blowing at all. That may not seem like very long, but in Texas, in our heat, it is an ETERNITY. I can't seem to find anyone else describing this same "issue" in their FFH, so I don't know if this is normal, and just an annoying design flaw, or if there is actually something wrong with my ac/cc. Any input would be greatly appreciated. :noobie:

I posted this data as a response to a question I received in the "Fuel Mileage" topic category, but I wanted it to be listed in the "Climate Control" topic category as well, since this is a more appropriate place for this data. Over the course of several days, I have monitored the A/C power draw on the MyView gauge, and the behavior was not at all what I had expected to see. So to begin with, the A/C power draw data for in the morning when I leave for work, when the temps are in the 85°-93° range in my garage (outside temp is actually around 75°-80°), the A/C power draw climbs immediately to about 2.5 kW, no matter whether I am in complete "Auto" mode or in semi-manual mode or in Max A/C mode. It stays at that initial maximum draw for only about 1-2 minutes, and then over the course of about another 1 minute, it drops to a final level fluctuating between 0.4-0.6 kW, and stays at the same low level for rest of the duration of my 30 minute commute. Even if I change the temp or fan speed or air flow path, there is no effect on the A/C power draw, no matter whether I am at the initial high draw or at the final low draw. This was the surprising part for me. Now if I change to Max A/C mode after reaching the final low draw (0.4-0.6 kW), there will be no immediate effect on the A/C power draw. But after about 1 minute, the power draw will very gradually start climbing, and after several minutes of this Max A/C mode, when I can no longer stand it anymore due to the excessive noise, air flow, and coolness, it has only increased the power draw by about 1 kW to about 1.5 kW. I don't know if power draw while in Max A/C mode would keep climbing since I am not able to endure the Max A/C mode any longer after I have reached my limits of endurance. So now for the A/C power draw data for my return trip from work, when the ambient temps are at true desert-level temps. For my drive home from work, when the outside temp is around the 107°-110°, and with my FFH having been parked in the shade, the power draw curve over time is basically the same as I mentioned before, with the max power draw peak being immediately as soon as I turn the A/C on, and the final low power draw being reached a few minutes later. But the difference during these afternoon high temps of the day is that the max initial power draw is about 3.5 kW for about 2-4 minutes, and then the final low draw is slightly higher, fluctuating between 0.6-0.8 kW. The A/C power draw behavior I saw when I have been parked in the sun at 105° is that the peak draw was around 4.5-5 kW for about 2-4 minutes, and the final low draw was the same 0.6-0.8 kW draw that I saw when I started with my FFH in the sshade. To reiterate, I basically saw no difference in the power draws that I saw over the course of several days that could be directly attributable to the varying A/C modes that I had selected. The only variable that seemed to affect the A/C power draws, whether it be the initial peak draw or the final leveled-off draw was the temp inside the car, which was directly correlated to the outside temp and whether my FFH was parked in the sun or in the shade. I monitored the A/C power draw while using various climate control settings, including "Auto" mode with various temp settings between 72° and 80°, and including various semi-auto settings, by changing the fan speed, the air distribution settings, along with changing the set temps, and even using Max A/C, and I did not see any immediate change in the A/C power draw when I changed any of those settings. As I mentioned, the only time I did see any change in power draw was when I left the climate control on Max A/C mode for several minutes after reaching the final low levels, and it would only increase by about 1 kW above the final low draw. Anotber new-to-me observation I have noticed is that there does not seem to be any truly manual mode with my 2014 FFH climate control system since the temp setting is always involved to some degree or another in a semi-auto fashion. Even when the fan is set to a manual, user-specified speed and the air distribution setting is set to a manual, user-specified air vent selection. I have not found any way to not have the temp setting involved in some way, since it always seems to change the output air temp to its own volition. So here is a table summarizing the A/C power draw data, for desert ambient temps, that I have detailed above. Initial Park Condition and Ambient Temp --------------------------------------------- Shade, 85°-93° Shade, 107°-110° Sun, 105° -------------- ---------------- ----------- Initial Peak Draw 2.5 kW 3.5 kW 4.5-5 kW Duration of Peak Draw 1-2 minutes 2-4 minutes 2-4 minutes Final Draw 0.4-0.6 kW 0.6-0.8 kW 0.6-0.8 kW So based on my findings and comments from others in this forum, my BKM (Best-Known Method) that I use now is that I start my summer desert trips in Auto mode, with an initial temp setting of 80°, and then when I start feeling too warm due to the decreasing air temps being output through the mid-level dash vents, I will then drop the temp setting by about 1-2° at a time, which usually eventually ends up stablilizing on a setting in the 74°-76° range. Then, at my final selected auto temp settiing, if my eyes start getting too dried out from the air coming out of the mid-level dash vents, located on either side of the steering wheel which I always leave positioned directly at my face, then I switch the air distribution to be dash vents (middle level) and defrost vents (upper level), thereby being a semi-auto setting. And then I rinse and repeat at the beginning of the next day.

I've never used the 110v power outlet in my FFH before. Today we were taking one of my granddaughters home and she was using her iPad, the battery was low so my wife handed her an Apple iPad 110v Charger, it was plugged into the 110v outlet and then into the iPad as we drove. The outside temp was 96F so we had the A/C set to 72F. Within 30 seconds of plugging in the iPad Charger the A/C became uncontrollable, the fans ramped up, a different fan-like noise could be heard from under the dash and in the air outlet vents and hot air came out the vents. We attempted to shut off the A/C, it was frozen and would not respond, but kept making that second undulating fan-like noise. I was able to pull over and shut the car down, we unplugged the 110v iPad charger and restarted the car. I could now shut down the A/C but that other noise continued, then slowly cycled up and down until it too stopped. When that odd noise stopped we were able to again control the A/C and set it to cool the car and then went along our way. The odd noise could have been the Inverter cooling system in action but why the Climate Controls were frozen is very strange. I don't see anything in the FFH OM that speaks directly to an iPad-like device overpowering the 110v Outlet's capacity but from now on I will not use the darn 'feature'. The HVAC system is scheduled to be replaced in the next couple weeks, I'll mention this to the SA when at the Dealer.
