What is the building code minimum clearance between a

What is the building code for the minimum clearance between a heating system and the AC coils that sit on top? We currently have an oil heating system with a Bryant AC unit. We plan to replace the Bryant AC and keep the heating system. The existing AC coils fits within a 24" clearance above the furnace, which is our maximum clearance due to the ceiling height. We live in Maryland.Furthermore, the existing system is built for freon and has 7/8 inch piping. Some vendors say they can use the existing piping with the new refrigerant.

Something is causing and/or making the water circulating

Hi - something is causing and/or making the water circulating pump to make loud noises when runing at random times during operation. But not all the time, just sometime and it's random... The pump installed now is brand new and one week old, and it's making the same noise as the pump I replaced which was two month old.... At this point I don't think it's the pump anymore.... I've bleed the system as best as I could, but that didn't help. Yesterday, I turned on all the faucets and showers and emptied hot water tank, the boiler engaged, filling up the tank and the pump seemed to work with zero noise.... later in the afternoon the pump starting the making the noise again..??? It's either a high pitch sound like a dog howl and/or like a gears are grinding...
