R290 into 410A system
Lightning zapped 410A inverter split system at son's house, easiest fix was to buy a whole new unit as can later repair zapped unit and use for shop that now is just wood heat.
.
Have used bbq propane for R22, how will that work for replacing 410A? Pressures will be a lot lower, maybe need to replace or 'finagle' txv?
