It started the first time i used my A/C this summer. Iniatially the fan spinned a bit then stopped and i left it on for few hours hoping that it would restart again. I later found out that it was because the breaker tripped. So i turned it back on, the fan started but no cold air. I once noticed for brief period (half minute) the exposed pipe was frosty, and never seemed like that again ever since. it just feels cooler. I tried to turn it on and off serveral time. every time i reactivated it by turn the thermostat from hight Temp setting to low temp, one of the two breakers tripped. sometimes i couldn't even turn the breaker back on. any clue where i should look at. I noticed two capacitors inside the outdoor unit. I don't see any reset button. Your help is greatly appreciated. Greg

Hi, I am looking to install a swamp cooler in my house. There has never been one before. I have two q's related to this: 1) How to determine the CFM of the unit. I have seen a formula (ft^3/2 = CFM), is this correct? Seems a little high since it computes a much higher CFM than is easily available (building centers...). 2) How to tie into duct work. What seems most logical to me is to tie into my existing furnace's cold air return. Is this OK, or are there reasons not to do so. If it's OK, do I then block the cold air return trunk from the house and only feed it swamp cooler air, or do I leave the "regular" CAR open and let both air streams mix? I would like to tie into the duct system since (by my thinking) each room would get some cooling; I wouldn't need to leave bedroom/bathroom/[any room I don't want the dog to have access to] doors open. FYI, I live N. CO, lately temps are around 100F with an RH ~40-50 at midnight, dropping to ~10 by noon and staying low for the majority of the day.
