Air Conditioners

When I use my air conditioners, I can hear the AC cycle on and off, but the fan never stops. Is this normal? I have the thermostat set to cool with fan on LOW.

YUP--if you have the fan set on low, the fan will run on low regardless of what the compressor is doing--the same is true if you set it on high. Set it to auto if you want the fan to go on and off with the compressor. As for the compressor cycling--normally, its a function of the thermostat calling for cool. Occasionally, the compressor will rapidly cycle from low to high and then off--that's probably not "normal" but the cause for this cycling remainds a mystery to me.

It's too much of a shock to my nerves to have both the compressor and the fan come on at the same time after it has been quiet for a while, so I always have my fan on low. The other thing with auto is that the fan comes on at high initially and then drops speed as the coach cools. Wonder how many people actually use the other speed settings?

YES: Fans on the A/C have (usually) 3 or 4 settings.

AUTO (Fan turn on and off, very annoying
Low
Medium (this one is optional)
HIGH (The best setting)

Why you ask is High best: Two well 3 reasons.
First. The greater the air flow, the faster the A/C can cool your space. This means the compressor shuts off faster, and saves electricity.

Next: Some folks report issues with the A/C when they run on low, like icing up and such.

Finally: And again this is my reason: The noise made by the fan is very quickly "Filtered" by your brain to the point where I often have to go check if the A/C in the "other room" is on or off (I simply can not hear it) it covers much of the noise from outside the MH, Kids playing, Cars driving by, that kind of thing. Makes for a peaceful night's snooze.

Personally I hate the noise, so I do like John & run fan on low all the time unless its AZ in the summer where low won't keep up. Up to about 95-100, fan on low works great for me. Above 100, fan goes to high.

I also run my on low all the time (temps permitting) the sound of the fan is like white noise and helps with sleeping. Auto during the day is okay.

A/C / Heat questions for Alpine limited 2006 40'

Looks like a one a/c is supposed to handle this coach.. Is that correct? Hydro hot handles heat... Is that also correct...??? I am used to my dual heat pump basement a/c with propane b/u heat in my winnebago. I am looking at this alpine and worry about the single a/c...

I can't imagine one A/C keeping up for a 40 foot MH. I would have thought WRV would have put 2 in the 40 footer.

"....looks like one A/C unit is designed to handle coach...." Alpines have two A/C units [requires 50 amps to operate]...what makes you think only one is needed???????

All Alpine Coaches have 2 a/c units. One in the salon and one in the bedroom. Where did this crazy idea of one a/c come from? If you go back to the original question it mentions "conditioners" plural!

All I know about this is that a friend of mine has a basement a/c in his Alfa motorhome and he hates it.

Don't know about a compressor going from low to high but rapid on/off cycling is usually an evaporator freeze ... it's called "short cycling". In most A/C units it's caused by the ceiling output side leaking into the input side.

You are right John. I was reading Cuemaker's post and thought he was the OP!
