Are there any special precautions or requests that I should be aware of if/when my contractor installs an A/C system in cold weather?
I have read that the charging of the A/C system becomes more complex since the amount of installed r410a requires adjustment.
Is this a routine adjustment based on the temperatures and volumes of the inside and outside components?
Should I request that the system be re-checked in warm weather?
My r410a system has not been purchased yet.
I am asking this forum in case there are requests that I could/should add to my contract.
