R134a refill question
My 2005 Civic LX sedan refilled it up to 45psi at 85 degrees Fahrenheit outside temp. The air conditioner seemed to freeze over in 85-90 degree Fahrenheit today when headed towards downtown Baltimore.After thinking I should thaw it out I only used the fan for 15-20 minutes not the ac and tried it and it started cooling again.. was it not enough coolant and it froze up? 45 psi @85 degrees Fahrenheit is the lowest the refill chart recommends. Should I put more refrigerant in it? If so how much? Any suggestions?

Re: R134a refill question
It's freezing up because its too low. Psi needs to be the same as ambient temp. So 85 psi. Need a set of manifold gauges to do this properly. Or pay a shop
