There are many reasons why an air conditioning unit does not work well: its temperature control may be set too high; it may have lost all its refrigerant because of a leak in the system; its compressor pump may have stopped working; etc...
If you cannot see anything obviously "set wrong" the best advice anyone should give you is to call a licensed Heating, Ventilation and Air Conditioning (HVAC) technician to advise you and/or fix it for you.
To know when an air conditioning unit (non-window unit) needs to be charged (needs freon), it will not cool properly or you can test it with the appropriate gauges (see related link below).
yes but you need to how much freon if may not be cost effective. Plus you need to know if it is the same type of freon.
all i know is that freon is put into air conditioning units in your car. it's what causes your A/C to be cold
When your air conditioning isn't cold
The best air conditioning company is really a matter of preference. A residential air conditioning system needs regular maintenance, which is usually recommended once per year.
when the air does not comes out cold in your ac will be a good time
I do not know of any freon diagrams. I would not recommend trying to charge your air conditioning sytem; it is very complex and the system is under high pressure. Take your car to a professional.
refrigerant 135a is the the standard freon used and sold at most auto parts/retail stores. You can even do it yourself.
When you are going to add Freon to a Toyota Camry, you need to know which type to add. You will need to put the Freon recharging coupler to the recharging kit, and get the engine to operating temperature. When the engine is at operating temperature put the air conditioning on the lowest setting and recharge the Freon with the windows of the car rolled down.
None that I know of and I have been in the biz 25 years, and I have been around many leaks large and small.
well you have to find the low ac pressure point which is located near the wall by the engine on the passenger side. just purchase some freon along with a pump and you can recharge your air conditioning. You cannot buy Freon! Freon is the registered trademark of DuPont's R-12 refrigerant-which is Dichlorodifluoromethane. You can buy R 134-A which is tetrafluoroethane. The term "Freon" is incorrectly used by people who think they know A/C theory.
No, not even a little. it needs to be reclaimed with a specialized piece of equipment. odds are that no one will know but if you are caught there are big fines involved
