Can I get longer extensions for this installation kit?

These were easy to install and cool very well. The best part is because you stay under 50’ of coolant lines you don’t have to higher a HVAC company to charge the lines. That’s it plug and play anyone with DIY skills can do it.

This is my third system to install and it went smooth with a little bit of planning. This one was my first experience with a dual head unit. We are planning another dual unit in the future. The instructions were clear and well written and the packaging was great.

This unit was easy to set up and has been working great this summer to cool my shop. Great to have wifi control since it is not in my house. I used the Auto parts store vacuum pump to pump down the lines. This works great if you purchase the conversion fitting and rent two hose systems from an auto store, since two are required and only one of the two made for autos will work.

Installation was easy. Excellent flares on the tubing. Good fan speed and low noise level.I had installed top-of-the-line units, and this is my first budget model. Really good value IMO

DELLA Vario Series 20000 BTU Dual Zone Mini Split AC (9K + 9K) - Up to 800 Sq.Ft.

Was a little leary about buying a mini split. This unit is awesome. The one key to making sure that you will get years out of the unit? Get an A/C guy to vacuum the system and make sure he does the pressure test before opening the lines for the freon.

I live in an old log house. Can't have a regular HVAC. Got this to replace another minisplit that I took back to Home Depot after 3 weeks. No issues with this system. Keeps the house cold in the Texas heat. Highly recommend.

DELLA Vario Series 20000 BTU Dual Zone Mini Split AC (9K + 9K) - Up to 800 Sq.Ft.

After a little research, I did order this mini split and so far I'm happy with my decision. Delivery took a little longer than I expected (it comes on rails)but otherwise pretty easy DIY installation. Just peace of mind these units have 16 ft lines so downsized if need longer like I do have to extra purchased $. I recommend two people to install it -it's much easier. Customer service responded pretty quickly via email. Both units cooling pretty well which was the purpose so everything is good. I've been using this ac for over a month so if something occurs in the future I'll update it.

I've had their single unit running for a few years in my building.12000. It's done well. Did entire installation myself.had to buy a vaccum pump.bought torque wrenches but think that was unnecessary.mechanics feel would be fine. Amazingly efficient.

Not a single complaint! Had an HVAC guy come install, said it was a great product! Easy for him to install, only took a few hours tops! This was perfect for our 700 sq ft tiny house. Even the few rooms that don't have a unit, like the bathroom, stay cool all day. All of the functions are perfect!
