We basically added freon to our home nouns con, but it does not gain cold as past, basically out in the open comfortable cool, why?
There are greatly more issues than freon to be considered.
You obviously don't know what you are up to, and that usually ends up costing big bucks.
are you certifed to handle refridgerent ? epa fine if your not do you have gauge ? most older home systems use r 22 done forgot how to read gauges short looking at them but that will be the only way you can properly charge a regular ac and boil pumps are totally different to charge make sure that both of the coils, inside and out, are clean afterwards adjust the coolant level. If the amount of freon is to high or too low, the system will not work
Did you use the correct type of freon?
Answers: Assuming your filter is clean, your outdoor condenser coils are clean, and that everything is functioning properly, it could be that he didn't get hold of the right charge of refrigerant in the unit. Refrigerant is designed to enjoy a certain temperature at a given pressure. Because of its make-up refrigerant will absorb heat and boil sour at a fairly low pressure. In an A/C system, the refrigrant will continue to engage that heat even after it has boiled sour. That amount of heat is called superheat. It can be measured by taking the actual warmth on the suction line near the compressor, and subtracting the design warmth of the refrigerant at the suction pressure that is being read on the gauge. An R22 system normally has a design superheat of around 15 degree. If the tech is reading a higher superheat than that, the unit is probably undercharged. Lower than that, the component is probably overcharged. Most manufacturers put a chart on their unit at the moment to reflect what the proper reading should be. Have the tech check those readings for you. It's a great insinuation point for proper charge.
