Is it safe for me to temporarily disconnect my air conditioner to put a concrete slab under it?

We have an outside A/C unit that the builders put on a plastic/fake stone that is 3' x 3'.  It has cracked and is now sinking into the ground at an angle.

I want to pour a 4' x 4' concrete slab but I'm not sure if we should have a professional come out to disconnect the hose and ground wire from the unit or if we will be fine doing it.  I just want it moved out of the way so I can pour the slab in the same place it has been.

Hi JL Schneider,

Ultra lightweight concrete condenser pads are now available, they are inexpensive around $50 -$60 dollars and can be easily installed.The price makes pouring a new pad a waste of time, as you will spend just as much money and have a lot more work.

Have your HVAC contractor do the work, he can elevate the unit and switch out the pads with ease. Have him service the unit at the same time, saving you the cost of a service call later in the year.

Actually, JLSchneider, it is not safe!

Disconnecting your compressor will release refrigerant into the environment.

The contents are under pressure and when released you'll be exposed to extreme temperature as well as several serious health risks.

These regulated gases are safest when handled by a trained specialist ... like Mike recommends.
