I keep hearing about the noise of those roof top A/Cs and I will admit that since mine are ducted they are not as loud as a non-ducted one... but....
The steady drone of the blower (if you just put it on high) is very quickly filtered by your mind, thus if you forget that stupid AUTO setting which turns the blower on and off and is very annoying... You do not notice it nearly as much as you do if you set them to annoying.. er, auto.
Now. The problem with strip heat in the A/C.. There are two school of thought
1 The wiring to the A/C can easily handle a 1500 watt heat strip. the outlets down below.. Not necessary. (I had one overheat on me). (I installed better outlets).
2: Warm air rises, thus putting a heater in the ceiling.. NOT the best plan, better to put the heat near the floor.. and that is exactly how I do it.
I use up to four 1500 watt space heaters plus some additional outdoor heat.
one in the bedroom (Special 15/20 outlet fed with 12ga and the only thing on the 20 amp breaker)
One in the living room.. same as above but 15 amp breaker (Did not have a spare 20 at the time I hooked it up)
One more in the living room, shares breaker with bedroom A/C. also shares break-out system that lets me power it off the park's 20 amp outlet when on a 30 amp site.
One hooked to the washer/dryer circuit (Currently in storage). If it's below freezing out I use them all
Basement has a string of C-9 Christmas tree lights, roughly 24 9 watt heaters and a 100 watt rough service lamp (300 watts of heat) plus a 150 watt heater if it is getting truly cold.
And I still have my propane burner for when needed.
Last night.. I needed none of the above.
