Problem has changed...
Hello all, this is my first post here so thanks in advance. I've been browsing through the site for 30-45 minutes and unable to find a problem like mine so I'll ask the questions.
Last night, my AC fan outside stopped working. I didn't notice it because the air return was drawing air, and I could hear the blower running from the attic. It started to warm up, and I went out side and the fan was not running. I did some online trouble shooting that said if you turn the air on, and hear a hum, try to spin the fan... if it comes on, then there is likely a capacitor problem... sure enough, I spun the fan and it fired up briefly. I killed it for the night (it was midnight). I came back this morning, replaced the capacitor, and away she went. I put my tools away and got the lawn mower going. Long story short, I fixed the capacitor problem several hours ago, and the temp in the house has not gone below 81 for 4 hours. I know that it is hot here in Houston (Heat index of 110 this afternoon) and I expect it to take a bit to cool off, but the air coming from the vents is certainly not 15-20 cooler than the air going into the return. I felt the lines outside the house going into the unit, and the large line is cold and the small line is hot. There is hot air coming from the fan so I know it's cooling something, but I cant get the air in the house to cool down to 73-76 where I usually keep it.
Any help is greatly appreciated.
