That's a good starting point. May just need a top off. When you switch over to A/C and pressure the button too, there should be a noticeable difference in output pressure. Are you getting that? Also, I hope you aren't using freon, as it was deemed a greenhouse gas and may actually be illegal to use now/in the near future. I believe it's been replaced with a refrigerant called R-410A.
