Yes you need freon if you own a heatpump, with a furnace/oil burner you could do without the freon.
freon?
Freon gas is used in refrigerators, air conditioners, ovens and all other types of these things.
Gas used in air conditioners are: R12 freon is dichlorodifluoromethane R134a is Tetrafluoroethane
Freon is not used in automobiles any more. Refrigerant is used.
The high and low Freon valves are located on the air conditioning compressor. Use the low Freon valve to recharge the air conditioning system.
Yes but you will probably have to install a service port.
Modern wall air conditioners usually do not need any coolant replaced during the life of the air conditioner.
Try chraging it with Freon. This is the most common problem.
Depends on the size of the unit and how bit or small the compressor is. There will be labels that will tell the technician how many pounds to capacity for Freon.
The most common for vehicles are R-12 and R134a freon.......... The most common for homes are R-22 and R-410A freon..........
If you mean freeze as in ice up it is probably low on freon.
