Perfect for our 18K install
Mark D. • 3 weeks ago
Our outdoor unit needed to be on the opposite side of the house from the indoor unit. This extension got us the extra reach we needed. Pre-charged so no special tools required - just connected it up and it worked perfectly.
Right size for the bigger unit
Kevin W. • 2 months ago
Make sure you get this one and not the standard size if you have an 18K unit. The larger copper tubing matters for proper refrigerant flow. Easy install, no issues.
