Solution: I'd personally check your refrigerant cost to start with simply because If the system is low on cost it's going to bring about the coil to freeze up and lead to a restriction within the air stream. Guideline could be the blower ought to make 440 CFM (cubic ft for every moment) of air for every ton. On a two ton process 880 cfm. This generally calculates out to generally be a couple of one/four to 1/three HP blower motor.

He also didn’t say to acquire a brand new Lock-Out swap so that could just have to be my contact I guess.

two. Slow or dragging admirer motor. Substitute motor or capacitor. I would want to understand the capacitor specs to suggest a replacement capacitor. I would wish to understand the unit’s model selection to be able to advise a whole new condenser enthusiast motor. Make sure you e mail us at anytime: [email protected]
