Condensing Unit

Today we are looking at condensing unit you may find outside of your house on the ground.

It doesn’t matter whether it is a Trane, Goodman, Carrier unit, they are all pretty much the same. Have the same components for the most part. There are a couple of repairs that we are going to discuss here, they are real common. I would say about 60% of the calls I go on are one of these two items. While professionals would charge you hundreds of dollars, perhaps even thousands of dollars to replace these components, the good news is that it’s something that you as a home-owner, if you have a little bit of mechanical skills, it’s something you could do yourself. It might seem kind of intimidating but there is really not a whole lot to it.

One of the things I want to talk about is this capacitor here. We are going to look at it a little more closely and it just has to have some wires going to it. Maybe four wires and there is really not a whole lot to replacing one.

 
If neither the compressor nor the fan motor would turn on than the culprit is most like this capacitor. You just unscrew one bracket which holds it in place, and you just replace the wires on the new capacitor one by one. They are marked COMMON, HERMATIC and PAN. So you will just the wire that is connected to the common on your old capacitor and put it on the new one and then repeat the process for the rest of the wires. That’s pretty much all there is to it.

The other thing is your outdoor fan motor, and it doesnt matter, you might have a package unit so if you were to go on the roof and look at your package unit, somewhere most likely on top of the unit you will see a fan like this one. It has a bird-guard grill which is there to keep the birds from getting inside of the condenser cavity. It’s pretty much the same operation where you have a package unit on the rook or a condensing unit on the ground.

 
Before you do any work on the condensing unit, you should always disconnect power to the unit by pulling out the fuse block from the fuse box. And I like to set it on top of the condenser that way it is always in sight to reassure me that it’s turned off.
