AC blows hot air after recharge
Yesterday I recharge my AC with R134a I used to
gauge it was low so I added it to the correct level
and now it blows very very hot air it was blowing
halfway decent cold air before I recharge it can you
please tell me what is wrong and how to fix it
You can under and overcharge AC. You get the same result. Hot air... did you use a manifold guage set? Red high side, blue low side and yellow recharge? Today for instance in my area, 83 degrees ambient air temperature. I should see 40 - 50 psi on low side and 175 - 210 on high side dynamic pressures. If you see the same pressures on each side you probably have a dead compressor. There are charts explaining all the possibilities on each side and what they might mean. Do you have a blockage? These pressures would tell you. Also is your heater vent door actuator working?
I didn't use a REAL set of a.c. gauges I uploaded a photo of what I used how come my air worked ok but it was low on the gauge so I add half a can till it was in the good section of the gauge and then it blows hot now?
I'm also in Florida it's very humid and about 95 degrees
95 degrees, 50 - 55 on low side and 275 - 300 on high side. I would invest in manifold set. Harbor Freight sells them for $50. One use and their paid for. Use 20% off coupon also. Not the best quality but I have had mine for 5 years now and have fixed my own several times and made over $400 from friends that refuse to accept FREE. Those cheap one time hoses are not the correct way to diagnose or recharge your system. I taught myself by reading and watching videos. It is dangerous so keep safety in mind. I look like a dweeb when doing it but I have had cans burst on me. Thinking about buying a tank and scale. -20 degree gloves, hard hat, goggles and ski mask. It has saved me. I also had cheap hoses burst. I invested in a set of mastercool from NAPA. 134a hoses.
In the good area on your garage also means while the compressor clutch is running. Is it spinning? Clutch is outside the pulley. This should cycle on and off every 45 seconds or so AFTER the AC has cooled down the car significantly. First turned on it should spin a while with your front fans also.
There are also some decent guage sets on EBay that won't break the bank. Some of these have the vacuum pump and O-rings and other accessories at good prices.
It kicks on the car idles up 2 1500 rpm n goes right back down but aur was kinda cold before I recharged my a.c. now it's super hot like it's blowing heat
Did you find the problem?
my ac was working. I added some Freon and it stopped working. turn out I had too much Freon in it. I turned my ac on and let some Freon started to work again. 2008 Pontiac g6
