Problem:  What size SlimDuct line set cover do I need to hold a 1/4″ x 3/8″ refrigerant line set, wiring and condensation line?

Solution:  SlimDuct recommends that you use the SD-77 series for installation of line sets for single mini split systems.  The dimensions are 3″ x 2 1/2″ and is made for lines up to 3/8″ x 5/8″

Spacing of the Indoor Evaporator in Relation to the Ceiling

36,000 btu. Heat Pump Mini Split

Problem:  What should the space between the indoor wall unit and the ceiling be?

Solution:  Ideally, you will want to leave approximately 10 inches between the ceiling and the indoor evaporator.  This leaves enough room for the indoor unit to draw in fresh air through the top and positions the unit high enough to maximize the cooling effectiveness throughout the room.  Cold air settles downward, so the higher the better.  You can mount the indoor evaporator at any level, but the best position is 10 inches below the ceiling. 

Dual Mini Split Air Conditioner Recommendation

Problem:  I don’t own any AC yet. I am planning to purchase one. I needed an advice on whether I can get any product that fits my requirement.  I have two rooms that need to be fitted with an AC. My initial analysis is that 1.5 ton would be sufficient for each. So I was wondering if I can purchase a split AC with one compressor (may be 2 tons or so) and two evaporators.  Is this possible? If so which is a good company to go with?  Are there any special considerations with such setup?

Solution:  You have a perfect scenario where a dual or multi split air conditioner should work great.  The ACDE12HP220 is a dual 12,000 btu. Inverter system with two indoor evaporators and one 2 ton condenser.  Each room can operate separately with its own remote controller.  Installation is the same as any other single wall mounted mini split air conditioner with the exception that you need to run two separate line sets to the indoor units instead of just one.  I would recommend either the ACDE12HP220 or the ACDE09HP220 which is a dual 9,000 btu. system.
