One of my three air conditioners is shot and needs to be replaced. I’ve already replaced one of the three about 2 years ago, so not worried about the install. My question is this, does anybody have a good method to get the old and new unit on and off the roof. Last one I did I was able to back up to the roof of my garage where I had easy on/off access from the roof. I’m full timing now and looking for another way.

The last one I changed out for someone, I used a borrowed extension ladder and a helper. We extended the ladder to about a 45° angle and I lowered the old A/C down the ladder with a rope while the helper guided it from below. We reversed the process for the new unit.

I have used Dutch's ladder method a couple of times, worked well.

Why not find a business nearby, someone like a lumber yard and offer a few bucks to lift the new one up and the old one down? I have a fork lift at my shop and would lift one for free just to help someone out.

When they changed mine they used a rope and pulled it up the ladder. The old one they threw off the roof. Mark

I would call a mobile RV service person. If I had to do it myself I would rent a scissor lift.

TREE.....ROPE.....PULL. Once lifted back MOho out from under. Lower unit to ground. Attach New unit and lift. Pull Moho back under and lower into place.

Just my 2cents.

Use a pulley.

Yep. Leave the new unit in the box wen you haul it up too. It slides easier that way.

Yep, I left out that detail. I turned the old unit upside down to lower it so slide smoothly going down.

Heh! I'm 77, Bruce. When someone offers to help with a job like this, I accept gratefully... ;)

I pulled mine up with a rope also. The thing that hasn't been mentioned
that I did is I left it in the box for a smooth ride then put the old
in the box and let it down.
They are not that hard to manage.

are you at a campground? if so maybe throw them a few bucks and have them pick it up with their backhoe.
I changed both of mine by myself. this will do you no good but I parked next to my deck and placed them on the roof. the old ones were thrown from roof into the back of my pickup

Two people and a ladder
Front end loader
A/C unit weighs far less than I thought at around 100 pounds or less.
Worst case rope the unit. set up your extension ladder to roof height
2nd ladder for you to get on the roof and pull it up the ladder

But we used to people and a ladder for one. and a front end loader for the other.
