The big obstacle that caused
us to call a certified HVAC tech for our DuctlessAire Mini Split system
was charging the lines with a tank of nitrogen to test them with a
proper gauge before releasing the pre-charged refrigerant from the
outside unit.
A tank for nitrogen would cost
around 100 dollars then you'd have to find somewhere to fill it with
nitrogen and then you would still need to have the proper hose and
fittings to hook up to the service port of the unit.
After calling 5 different
places in our area Anna found a company that would come out and finish
our system.
The tech was very nice and
professional and wrapped it all up in just over 2 hours. I'll save the
rest of the details for my next post.
