Which WiFi Channel Frequency Bands Does WiFi Support?

How Do I Choose the Right Size for a Mini Split?

The size of the mini split depends on the room's dimensions and specific needs. For example: • A 400-square-foot room typically requires a 9000 BTU mini split. • A 550-square-foot room needs 12000 BTUs. • A 1000-square-foot room needs 18000 BTUs. • A 1500-square-foot room needs 23000 BTUs.

Can I get longer extensions for this installation kit?

Yes, you can purchase a longer lineset separately. Please note, if the extended lineset is longer than 25 feet, additional refrigerant will be required. Make sure to consult a professional HVAC technician for proper installation.

DELLA Vario Series 35000 BTU Dual Zone Mini Split AC (12K+24K) - Up to 2050 Sq.Ft.

Installed myself. Had to buy an AC gauge and vacuum pump, then learn how to use them. Wasn't too hard. I mounted the outside unit on the second-story wall using a mounting kit. Had to frame a stud from the inside to carry the weight. Great value. Dehumidifier works great. Quiet operation. Haven't tried the heat function yet.

Install went well. Unfortunately my manifold did not make a good connection with the unit and I thought I had leaks. AC company came out to pressurize the lines to look for leaks and all was fine. Been a bit since buying and feels good to have them up and running

Super easy to set up and keeps my shop temperature regulated! Love the airflow and circulation. One remote controls both units if you want to just have one remote!! Arrived broken due to the carrier and got sent a replacement right away!

We installed it in a 1200 sq. ft steel warehouse with almost no insulation in the walls and none in the roof. It cools very well in coastal NC. Pretty easy to install. You will need to vacuum the lines before opening the freon valves. The outside unit is very heavy get help moving or lifting it.
