My 1st floor central A/C not having any cool air, the indoor fan is working but the outdoor fan is not working. I turned on the 1st floor A/C by mistake without removing the outdoor unit's cover I put on over the winter. I realized the problem after 1st floor A/C run about 1~2 hours. Would that do any damage to the outdoor condenser? Or is that the reason why the outdoor fan is not working? I had similar problem with my 2nd floor A/C (in attic) about 2 years ago. There was no cool air made and outdoor fan was not working. I had repairman came in and added 4 lbs freon to the 2nd floor unit and 1 lb. the 1st floor unit. How often is it to add more freon? Would low freon be the reason to my 1st floor A/C outdoor fan not working?

Thank you in advance for your help!

That was in no way good for the unit. you should never have to add freon to a unit. If he added 4 lbs to one unit he should have looked for a leak. I would chck your breaker having the cover on may have triped it. The check the compasitor outside.

This my friends is why I advise my customers to not cover their units in the winter,, the weather doesn`t hurt/harm them in any way,, if they insist,I advise nothing but maybe something like a trash can lid laying just on the top with a few bricks to hold it down, just to help keep the leaves out of the unit


Its very easy and possible to burn up and ruin the unit

Thanks so much for your response! Did I get ripoff by the repairman? 4lbs are lot of freon, I wonder what's the freon capacity for each unit. The repairman didn't say anything about the leaking, but after adding freon, my 2nd floor a/c unit run with no problem. Both of my a/c units are pretty old, ~15 year old. Is leaking a popular problem for old units like mine. I am thinking to replace with newer energy efficient a/c models, but afraid of the hefty cost. I heard there are many central a/c makers offering huge incentive and big rebate to promote their products under current tough economic condition. Any recommendations on good models and cost levels?

I checked the breaker on my main electric panel, it was OK. What's the compacitor? There is only one small metal box hooking up to the outside unit with a "disconector" you can pull out inside. Where do I have to find the compacitor? Maybe my unit is too old? Its compacitor is located inside rather than outside? What's the function of compacitor? Thanks so much!
