The suitable answer for this question is “NO”. A larger heating system with more capacity delivers less comfort and costs more to operate. An air conditioner is at its least efficient when it is first turned on. A system with too much capacity will run in numerous short cycles, turning on and off repeatedly, therefore causing it to be less efficient. Also keep in mind that an air conditioner only removes humidity when it’s running, so a system with shorter run cycles doesn’t remove humidity from the air very well.
