Question about Heating & Cooling
Two things are the most likely culprit. First check ytour inside coil with the unit running for 10 minutes or more and see if the coil is sweating there should be water running off of it. Also after one hour is there ice forming on it. These problems are lack of air flow which is caused by restricted air flow caused by a dirty filter dirty coil (which you have already taken care of) or your blower motor may not be kicking into high speed. Your motor will start and then after it gets to a certain speed it switches to a high speed. After running only 15 minutes if your blower motor is hot to the touch. Be careful some will cook an egg. If it is hot not just warm it is bad and needs to be replaced. Also if the fan is not running properly you can not get reliable readings with your gauges when adding freon. So if this is the problem then you may have to have the units freon cked again. If the line is not sweating at the outside unit where it goes into the unit the freon pressure is not right. The larger copper line will be cold and sweating the small line will be hot to the touch when the system is balanced and running properly. I hope this helps
