[Richard Armstrong]

If there is no gas there is a leak. Obvious but gassing a system with a 
known leak is actually illegal. Also the system needs to be vacced down 
before re-gas. These re-gas home kits are pretty shite to be honest and 
not worth the money. You need proper gauges and a vacuum pump.
However If the compressor actually kicks in (ie the 'nose' plate on the 
front turns with the pulley) then either the LP switch has been 
by-passed or you have enough gas to run, but not enough to produce 
effective cooling - which is a much better scenario.
There are 3 systems which have to work together to make the HVAC system 
effective (elec, Vac and gas) and any of them being defficient will 
render the cooling very lacklustre at the least.
best get in touch off line and we can sort something out.
