Hi,

I'm sorry, but out policy is to do everything online. If you do decide to try it, I'll help as much as I can from here. Plus, the owner of the site is excellent with A/C, so we can always ask him for help if we need it.

The biggest part of this job is you need to evacuate the A/C system and then it will need recharged when done. I say the that is difficult simply because you likely don't have the equipment to do it. I will attach a link that shows how it's done. There are a few things that need removed, but it should't be too hard. However, I don't know what you are comfortable with.

Here is the link I mentioned. Take a look through it.

Let me know if I can help in any way.

Take care,
