Removal of old HVAC system


I am wanting to remove a functioning split heat pump system from a house and was wondering if it is a feasible diy job? There is still refrigerant in it and it still runs.

I am fine doing the electrical disconnections, but was curious as to how to go about sawing/disconnecting the refrigerant lines.

Thanks!

Are you sure you want to decommission and remove the system?

I would have a professional come over and discharge the refrigerant. Do not saw apart the Freon lines. If you do it yourself and mess up, the Freon is under pressure and could spatter all over the place and give you frostbite if it gets on you. Can cause eye damage.

Not a DIY project. Unless you have the ability (tools) to reclaim and are licensed to do so, hire a pro.

I am a huge fan of DIY, but this is not the area you need to try and save money on.

Cutting refrigerant loose into the atmosphere brings a $10,000 fine.

DIY by calling a tech yourself.

I'm pretty sure the EPA would fine you big time if you released freon (like $10 grand or so). I think you need a licensed HVAC guy to pump out the freon. After that you can have at it.

When I took my old system out, I closed the liquid line at the outdoor condenser and let the compressor suck it all into the condenser. With it running, I could hear the compressor sound change. After several minutes, I closed the suction line and proceeded to disconnect the copper lines.

There was no loss of any refrigerant from the system, no hissing, etc.

I then sold the old system to a guy who had to add just a little to his installation because of his lineset being longer.

I did this at the recommendation of an HVAC contractor. (prior to knowing there is a fine of 10k)

Thanks for the great input. I'm probably going to call a tech to do the job, as the equipment is still under warranty and I don't want to void it. I thought if it was a simple process that I might have at it, but it sounds like there's just too much to risk.

Thanks again.

Actually, its not a $10,000.00 fine.
Never was.

It started at $25,000.00, its now over $30,000.00

But a judge can lower it.

Were you planning to move it within your property? I'm not absolutely sure, but I believe that a warranty is voided if the equipment (furnace or condenser) is moved.
