I have a 30 year old (Flame Master?) unit that worked good for about 5 years but last week i turned it on and the house wasn’t cooling so i went downstairs to the furnace to find that the line wasn’t very cold i thought "Great now i need to have the thing recharged." The capacitor is good the unit starts up normal with the side panel removed i hear the Compressor kick in when i push the Contactor with an insulated Screwdriver. So i am beginning to think maybe its a refrigerant problem. But i came here as i have no further experience with HVAC.
Its 30 C outside im melting!!!!
