Roof mounted 15k air conditioning
Hi, My 15k roof mounted AC unit isn't providing sufficient cold air to cool the fiver temperature down. My question is: can we add coolant to these roof mounted AC units? or, are all those units sea...

Adding refrigerant would not be the answer unless the unit wasn't sufficiently charged in the first place. Possible but not likely. That said if somehow it wasn't properly charged at the factory or developed a leak there is a way to tap into a closed unit to add refrigerant. Unless you have the equipment to measure low and high side pressure and a leak detector you should leave that to an A/C tech.
If it's not an issue of the A/C putting out less than it's suppose to adding another A/C (cost) is going to depend on whether you already have 50 amp service. If you have 50 amp service adding a second A/C would require minimal new wiring and you shouldn't need a new converter. If you currently only have 30 amp service then it becomes a more involved and more expensive project (wiring, new converter in addition to the new A/C unit).
