Central AC - DIY

Installing a Central AC: This is NOT a DIY. It's always installed by a professional.

Replacement of AC: AC replacement labor is pretty expensive at $4K per installation just in labor cost. It's definitely a DIY. Here's 2 part video explaining it:

Repair and Maintenance: Most of the repair of Central AC is around Freon leaking, which is a very common issue. Some Freon leaking is OK, as you can just top off every couple of years, instead of trying to find the leak and fixing it. However, AC repair companies which come and top off Freon charge a lot of money, usually around $100/lb, while you can get freon for around $10-$20 per pound.

Look for High side and low side pressures to be inline with what it's supposed to be.
