I have a problem with workspace issue. I have a heat pump in a service yard which is 71" x 72". If the new heat pump is installed with the 36" clearance from the meter it puts in in a corner with only 5.75" from wall. This does not allow heat pump clearance need. If the unit is replaced on the same site it was before it sits only 31" from the wall the meter is on. The unit replaced was not the original one being put in around 1995. In addition the meter is only about 20" on one side from the wall of the service yard. Could the set up be consider "grandfathered" in since to bring it up to code the service yard (in condo) would have to be bigger or it might be possible to move the meter.
