Need way more info.
Somebody should make a form that has to be filled out.
Return air temp
Supply air temp(taken as close to the coil as is practical)
Outdoor temp
Liquid line pressure and temp
Vapor line pressure and temp(if In heating,make sure its the true suction line between the reversing valve and the compressor.)
Compressor amps
Get some, or hopefully all of these measurements and the knowledgeable people here will have your issue solved in no time.
