Today I noticed that the air conditioner is not blowing as cold as it normally does. It is the R134 refrigerant type. How do I know if it has a proper "charge"? The older systems had a sight glass that was handy. How do I add more if needed? Same as the older Freon types?
Thanks !
A set of gauges to do it right. Some of the refill kits come with a gauge so you can at least measure the low side.

You need a set of gauges for starters to determine the hi and low pressures relative to ambient air temp and humidity.
