Automotive Freon is R-12 (or the new R-132 and R-134). Central air freon is R-22. They are not compatible because of their different boiling points. R-22 is being phased out through the year 2010, but there is no standard replacement.
overcharging a central air unit system with refrigerant(freon) will cause the head pressure to be?
low on freon
yes
get it to a shop and let them do it
I just had 2 pounds of Freon added to my central A/C and was charged $30 a pound.
Actually no technical skills needed to check the Freon level. Home central air conditioners have a Freon scale on it. One just need to read the scale and determine whether the level of Freon is sufficient.
brazing
it simply means you have to add freon to ur air conditioner....you can buy freon at any auto parts store.
Yes.
Learn how to spell
The refrigerant (freon) in any air conditioner should last the life of the unit. If not, you have a leak.
All air conditioning units use Freon, a chemical that when circulated helps to keep air cool. The kind of freon used in both devices is not the same, and chemical solutions with different amounts of each are needed to get the job done.
