Which is the right heat kit for my 2/3 ton MrCool universal heat pump and air handler? 10kW or 15kW?

Both kits will work with your universal heat pump. Make sure you properly calculate how much supplemental heat you will need when deciding between the two. If necessary, you can use the Quick Sizing calculator located towards the bottom of our Sizing Guide to help you figure it out. Alternatively, you can always give us a call and a member of our team will help calculate this and assist you with deciding between the two kits.
