MRCOOL 50 ft. Pre-Charged 3/8" x 3/4" No-Vac Quick Connect Line Set for Central Ducted and Universal Series, NV50-3834

I bought the MRCOOL 50 ft. Pre-Charged 3/8" x 3/4" No-Vac Quick Connect Line Set for Central Ducted and Universal Series, NV50-3834 as part of a heat pump system I installed myself, and based on a quote from a local HVAC contractor for their 18 SEER system, I saved $25,000 too! The original 100,000 BTU 80+ furnace was retained as a blower and emergency heat only. Integrated backup heat was not required, because this new system is still more efficient than my furnace down to -5 degrees, which we will never see in my area. However, I still have the option to switch to my 120 volt gas heat furnace if I am running on a generator due to a power loss, because the 240 volt heat pump is too much for it. The actual equipment install was easy compared to pouring a pad and crawling about under my house to pull and hang 50’ of the two refrigerant lines. Instructions were very clear to follow, and I highly recommend using a torque wrench for the line set fittings. Now we enjoy a more efficient heat source and AC too. Would I do it again? Yes!

Works well. No installation problems
