    Min. / Max. Loading

    12,000 / 24,000 BTU/h.


    Every indoor unit attached will operate at a random, self regulated capacity, based on the actual demand it measures from the zone it is serving (Between 30% to 100% of its rated capacity or OFF). Outdoor unit will also self regulate its output capacity, based on the total demand it reads from all of the simultaneously running indoor units at any given moment.

    With multi split systems, the total demand from the outdoor unit, shall seldomly exceed 67% of the total available capacity of the combined indoor unit group due to load fluctuations. Although very seldom, if and when the total demand from the combined indoor group exceeds the rated capacity of the outdoor unit, the capacity of the each indoor unit will be annotated accordingly.

    For high demand heating applications, max loading limits may need to be reduced by 10-15 % to avoid under-performance risks at some extreme conditions.

    We only ship to the 48 contiguous United States. No shipments to APO/FPO addresses, AK, HI, PR or other US Territories. No international shipments. Due to the size and the weight of our equipment, we can only utilize well known freight companies for shipping. Each shipment will be palletized, strapped down and wrapped in stretch film to protect against damages during transit.

    Upon arrival you may ask the driver to break down the palette into individual cartons to unload the goods from the truck easily. We generally include Lift Gate service. This will arrive as curb side delivery. Trucker will unload the goods from the truck to ground level. If you must have inside delivery service, there will be an additional charge which needs to be paid separately and coordinated with the freight company. We also allow free pickup from our main distribution warehouse, located in Miami area. Equipment we sell is not suitable for express or courier shipping because of their weight as well as high risk of damages.

    Due to higher than expected order volume and busy sales season, larger orders may take an extra 3-5 days to be prepared for shipment. We are working around-the-clock to ship out all orders in a timely manner, and will communicate with you if there are any unexpected delays or questions.

    We prepare each shipment within 72 hours after the receipt of payment (only during weekdays). Trucking companies usually pick up same day or a day after we call them that the shipment is ready. The transit may take any time between 5 to 8 business days and in rare cases up to 12 days.

    We will provide tracking information after shipment. Please contact us in case of any shipment delays.

    Ask a Question
    • I know 25 ft per lineset is the precharged max, but what if I use a 16 foot lineswt for 1 head and a 33 foot line set for the other, will the second set still need to be charged even though it is under the 50 foot of charge in the unit?

      As long as it adds up to 50' or less you're covered. So with 49' total you would be good there.

    • What ambient temperature is this good for? -15* F?

      This system heats down to -13°F outside temperatures.

    • Can I connect a 12000 and a 9000 to this unit

      Yes you definitely can.

    • If I buy a dual zone YN020GMFI22M2D, can buy install one indoor unit now and then buy the second indoor and install at a later date?

      Yes you can, that would not be a problem at all.

    • What AMP Breaker does this require?

      This would take a 20A double-pole breaker. The corresponding wire would be 12 AWG, with 2 hots and a ground, no neutral.

    • Can I run a single 18kbtu indoor unit with this outdoor unit.

      You cannot, you would need the triple-zone system, which is the smallest multi-zone that can take an 18K BTU head. Click here for more info.

    • Do both indoor units have to be heating/cooing to the same temperature or can they be set independently?

      The two attached heads can have their set temperatures be indepedently configured, but they must be in the same mode (of either COOL or HEAT).

    • free shipping?

      Yes all prices include shipping.

    • What size hole do I need to drill through the brick for the refrigeration lines for an 18K dual system?

      It would be a 2.5" diameter hole per each set of lines.

    • REFRIGERANT R410A Pre-Charged Outdoor Unit, accommodating refrigerant line lengths up to 25 ft. per circuit. The indoor units have a 33 ft and 50 ft line options. Can they be used with this outdoor unit?

      Yes they certainly can, but you will likely need to top off the condenser with some additional R410a to accomodate those longer lines.

    • Is it possible to run 2(2) 9,000 btu inside units with (1) 12,000 btu Duel split outside unit?

      Yes, this is a valid combination. See all combinations here.

    • Can I run a 9k and an 18K off this unit. In Okeechobee Fl

      The dual zone system cannot take an 18,000 BTU indoor unit. The triple-zone is the smallest multi-zone condenser that can. For more info see our matching table here.

    • Can i run (2) 12,000 BTU units on this outdoor model

      Yes, that would be a compatible configuration.

    • Can a 9000 and 12000 wall units be connected to this dual zone and if not what outdoor unit would be needed

      Yes they can, this would be valid.

    • What outside temperature does this unit cease to heat at?

      It would continue to heat down to -13°F outside temperature.

    • Can I wire two 9000 wt mini splits with this unit

      You cannot. These are the wall mounted 9,000 BTU units that are compatible with this condenser.

    • what size breaker & wire do I need

      It would take a 20A double pole breaker with 12 AWG wire.

    • I have a dual head unit can I run one head on air conditioning and the second head unit on heat at the same time?

      You cannot, it will throw a conflict error.

    • LINE LENGTHS UP TO 80 ft, Is it possible?

      You can have 80 ft for one indoor unit, but the maximum total that should be connected to this condenser should not exceed 100 ft combined.

    • Can I use only one indoor unit while the other unit remains off for a certain period of time?

      Yes you can, this would not be a problem.

    • Can I hook a two 12,000 btu heads up to this unit?

      Yes you can, this is a valid combination.

    • can i hook a 18000 btu and a 9000 btu to this unit

      You cannot. For an 18K head, you would need to use the triple-zone unit.

    • What is the minimum outdoor temperature this unit will operate at?

      Heating: -13°F / Cooling: 5°F

    • Would it be possible to install just one indoor unit then in a few weeks add a second indoor unit (understanding that the proper line set evacuation must be performed each time) ?

      This would not be a problem at all.

    • what amp breaker does the dual-zone 230 volt 21.3 seer require?

      This particular unit takes a 20A double-pole breaker with 12 AWG wire.

    • How can you connect a 12K indoor unit to the dual or three zone outdoor? Isn't the 12K indoor 1/4 x 1/2 & the outdoor 2 or 3 zone 1/4 x 3/8 only?

      All multi-zone condensers come included with the required adapters for this purpose.

    • can I hook a 9000 btu and a 12000 btu to this unit ?

      Yes, this dual can support 9K+9K, 12K+9K, or 12K+12K configurations.

    • If paired with 2x12k indoor unit, does it give me 24k continuous cooling or is it going to be only at 18k rated continuously?

      You can connect a bit more in capacity than what the outdoor unit itself is rated for. This is useful for when you're using one unit at a time. In the event that both of the indoor units are on and running at full demand at the same time (rarely/never happens), then the total combined BTU output will be attenuated down to the rating of the outdoor unit, in this case 17000-19000 BTU.
