I replaced my central air heat pump myself last spring. Outside unit and inside air exchange.

The inside unit happened to fit pretty well with a little adjustment in the place the old one (from the 1980s) had been, and I made my own connections to the ductwork. I placed the 2 ton outside unit on the pad where the old one had been. I did have an AC company come and remove the Freon from the old unit, then I cut it up and took it to the scrap yard.

I was able to do this with no vacuuming lines as they sell precharged kits with lines similar to mini splits. It's been over a year and it worked like a charm through summer and winter. It took about 5 days or a week including removing the old unit, pulling the lines under the house, setting the inside and outside units and buttoning everything up. The reason it even took a week was a I did it entirely myself including moving the units with roller logs.

I saved over $6,000 from what I was quoted from an HVAC company which I felt was entirely worth a week of manual labor.
