Hiring an HVAC tech to help with Mini Split install

Hiring an HVAC tech to help with Mini Split heat pump system.

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.

I'm not surprised you had to call around, very few places will work on customer installed equipment! Glad you found someone.

I have the vacuum pump, gauges, and tools to do the install but the nitrogen issue is my problem also. If I can find someone with the nitrogen tank I would rather do my own install. I would like to install three small units and my neighbor wants to do one or two units so paying a company to do the final install could cost quite a bit. BTW, home owner installs can void factory warranty.
