Do you love the MRCOOL Universal 20 SEER DC Inverter Unitary central heating and air conditioning system? Do you wish that you could more easily fit the Universal into a split system with a furnace? Or perhaps you would like to install the Universal into a mobile or manufactured home? If so, then you’re in luck!

We are now happy to introduce to the public the addition of the Universal Cooling-Only Condenser, the Universal High ESP Air Handler, and the Universal A-Coil to the Universal Series! All these awesome units are coming to dealers near you this summer 2021!

Universal Cooling-Only Condenser

The Universal Cooling-Only Condenser has been designed with versatility and efficiency in mind. With its compact side-discharge design, this Universal condenser ideal for places where limited space is a factor. It also offers different options when it comes to installing and connecting the refrigerant piping. These include soldering, flared-screw connections, or the MRCOOL signature No-Vac, Quick-Connect Line Set, for DIY installers or those who want to simplify and shorten the installation process. The Universal Cooling-Only Condenser comes complete with multiple safeguards that protect and monitor the unit to help ensure safe and smooth operation over the life of the system. All of this in a unit that is capable of a 20 SEER rating.

Universal High ESP Air Handler

The new Universal High-ESP Air Handler has been designed for use in high static pressure applications such as a manufactured or mobile home, or in a system that has restrictions in the ductwork which would place a strain on a conventional air handler not rated for high external static pressure. This air handler is equipped with a powerful and efficient DC fan motor that includes a fan with blades that are designed for quiet operation while still providing dynamic performance. The unit is capable of reaching a maximum static pressure of 250Pa. It offers multiple installation positions (vertical, horizontal left, or horizontal right) for an easy fit into many applications. The Universal High-ESP Air Handler also uses a durable metal filter that is both easy to clean and corrosion resistant to ensure it has a long service life.

Universal A-Coil

The Universal A-Coil is a versatile and adaptable option for your home comfort. It can be paired with other Universal units or as a replacement for an outdated, ineffective A-coil in your current system. The Universal A-Coil offers quieter operation and quick installation than many competitor models. It also features a liquid pipe designed to guard against excessive condensation. That could save you from costly property damage. It is equipped with multiple safeguards including protection against, high-pressure, high-discharge temperature, overload, IPM, and PFC in order to ensure effective and efficient operation for the life of the unit.

  1. Greetings!
    I would like to be notified when the “cooling only” unit is available!
    This will be absolutely perfect for my application…

  2. Will there ever be Hyperheat outdoor condenser matched with a 2/3 ton indoor handler? Can the higher performing Olympus series outdoor units be matched to the universal handlers?

    1. We do not currently have plans for that. The mini-split condensers are not compatible with the Universal system. The Universal is extremely efficient, though, and it displays impressive heating performance, with a 100% heating capacity at -5°F, and 78% at -22°F.

      1. I was sold a 60k btu the 4/5ton slim condenser dual inverter n heat pump with a 4/5ton universal series conventional cabinet air handler.

  3. When will the DIY Mini-split systems become available. I ordered the 36 BTU [18 btu & 18 btu] system back in May 2021, and now being told it won’t been until late July before the system is back in stock.

    Is this true?

    1. That would depend on the dealer and their inventory level. I can tell you that the DIY is a fast seller. However, most dealers should receive significant quantities of DIY product throughout this month (June).

  4. Hello, can the new ESP Air Handler be installed in the Downflow application?
    The Ductwork is under the Mobile Home so the Air Handler would be positioned upside down.

  5. Will the new ESP Air Handler have a down flow conversion kit available in the near future? The Ductwork is under the Mobile Home so the Air Handler would be positioned upside down

  6. Hello!
    I have a near-new furnace that is mounted in my garage ceiling (ductwork is overhead. I am interested in a cooling only unit that would work within my existing ductwork.
    It seems like the universal cooling only unit may fit that requirement.
    This would need to get a DIY install as there is no dealer (according to your nap) near me (Oak Harbor, Washington). The nearest is over 4 hours away.
    When will these units be one available and what would their cost be?
    We tried a mini-split at the time our furnace was replaced but did not like it because it ran non-stop and constantly blew cold air no matter the temperature setting. That’s why I want to go to a central unit.
    Thank you,
    Terry B.

    1. The new Universal units should be available before the end of the summer. Since we do not sell directly, we do not set pricing, so you would need to check with our retailers. One option would be purchasing online and having a local HVAC technician install it for you, if you were considering a traditional installation. Any HVAC technician can install and service our products. Take a look at for more information.

  7. I have been looking at your complete system ac units at Lowes, Where is this equipment made and who manufactures it for you? Thanks , Alan

    1. Depending on model, MRCOOL products are manufactured in the United States, Canada, and locations in East Asia.

  8. I skimmed though the installation instructions on my Model MDU018048060
    Condensing Unit where I remember reading about the compressor could rotate in the wrong direction. Could that damage the compressor ? How do you Phase the wiring to prevent this from happening ?
    I haven’t been able to find that place in the instructions sense. Please direct me to that
    place in the instructions.
    Thank you for your assistance !

  9. Can I run a DIY multi unit (12k and 12k) 27K BTU ac condenser having only installed one 12k unit? I will not be able to install the 2nd unit for several weeks.

    1. No, we would not recommend operating the condenser with less than 50% of operational capacity connected.

      1. May I ask why it needs 50% capacity if it is a multi? One would think multi would be designed from a single to full capacity thus allowing less than 50% capacity.

        1. The multi-zone condenser must have sufficient coil capacity and lineset length to absorb the refrigerant flow and pressures developed by the compressor.

  10. I need a new AC and have An old gas furnace that still works. I was thinking of a universal split to work with my gas as backup. No one here in Greensboro NC sells your system. Where can I get one? What do you recommend?

  11. Hi

    I have been trying to find a Mr Cool third generation DIY with dual head from any of your suppliers in around a 3 ton model with 25 foot line sets. I have a home with 2 floors about 1000 square feet. I like model number DIYM236HPW03BK2. I have been unsuccessful in finding anyone that can sell me a product similar to this. Can you please contact me and tell me where I can order what I am looking for?

    Thank you


  12. New Universal Units Soon (5/28/2021)!
    Is the Universal A-Cool available to order now (7/23/2021)?
    Need the Universal AC working with Signature furnace ASAP.

    1. Unfortunately the world is in what’s being called the “Logistics Apocalypse”. Universal A-Coil is coming, unfortunately it’s just taking longer to get onto dealer shelves than we would have liked.

    1. The answer will depend on what specific TXV you are referring to. If it is the TXV for the Universal air handler, then yes it is compatible.

  13. Dear Mr Cool,
    I have a unit that I had purchased about 5 1/2 years ago from Ingrams water and air company online after about a year of using it I was concerned that the air handler would never shut off it always ran. Being new to this technology I wasn’t sure if there was a problem or not so I contacted Ingrams water and air and they told me that there was a defect in that unit and there was nothing that can be done about it it was a manufacturing defect. I Also ask them how many units have you sold like this and he actually replied about 400 I have a unit that the air handler never shuts off and continuously runs I will send you pictures of the model of the air handler and the outside condenser information I really like your new Mr. cool universal units the 4-5 ton units I would be very interested in replacing this unit with that one. I felt that they should not have sold me a unit that had a defect in it especially not telling me until I inquired about it I also noticed after I installed this unit that they sent me A unit that was manufactured two years prior to me receiving so it was obviously an older unit that was left on the shelf for a long time my question is what could be done about this unit and I don’t feel like I was treated fairly as a customer. This has been on my mind ever since I installed this unit and I would like to make it right somehow.

  14. I read on one of your blog post comments that you are releasing a new model soon-ish that is compatible with downflow setups for the Universal lineup. Is that still coming? If so, are you able to give a rough estimate on when they’ll be available for purchase?

    1. It was supposed already be here, but the 2021 Logistics Apocalypse has delayed the arrival of our shipments. We’re hoping they arrive in the next few weeks.

  15. Been waiting… When will the Universal A-Coils finally ship out? When will you have AHRI certificates for the A-Coils to be used with the Signature Series Furnace? My utility provider requires an AHRI certificate to qualify for rebates.

    1. The A-coils have shipped. The problem is getting them into dealer hands, since logistics have slowed to a crawl right now. We hope to have them available soon.

  16. I need a 3 ton universal A-coil for a Downflow setup, so what modular blower would you pair with it? Or could you give me a list of everything I need for a 3 ton downflow setup with the Quick connect lines?

  17. I am the Proud owner of a MRCOOL 4/5 Ton Universal Air Conditioning System. I have been in the Air Conditioning industry for over 50 Years, as an HVAC Technician, Service Manager, HVAC Contractor then a FACTORY SERVICE Representative. The Inverter technology by MRCOOL is revolutionizing the Air Conditioning industry. In my opinion, it is leading us into a new paradigm. Place your trust in MRCOOL, you’ll be glad that you did.

  18. I purchased a ductless DIY unit from you last year and was well pleased. Now i would like to install a universal unit to fit in my existing duct work. Does your 3 ton unit come with charged lines and a wiring harness as i want to install it myself?…………Thanks…..

    1. You can choose to have it installed with pre-charged line sets to make for an easier installation. What comes with the Universal may depend on where you purchase your unit from, but typically it does not come with the items for wiring.

  19. We have a application where we have a space of 1,200 sq. ft. serviced by a high efficiency natural gas forced air furnace without air-conditioning but duct work is present for delivery of heat. Is the universal a solution for our situation to only add air-conditioning?

  20. Hi can you guys recommend me the best option for my house is 900sf ,2 bed ,kitchen, living room and small bath.
    We like have a heat pump because don’t have gas in the house, but we don’t have space in exterior walls, we rather have ducting from the ceiling.
    Please advise.

    1. If you’re interested in the Universal central heat pump split system, then we might recommend a 2 ton unit, depending on multiple factors including insulation, sun exposure, the number of people in the room, and more. Take a look at for information regarding the Universal’s retailers.

  21. Are there any plans to allow the DIY mini split 24k or 36k air handler to be paired with the 2/3 ton Universal condenser?

      1. I installed the DIY mini split 24k unit, but was wondering if it is technically feasible to swap out my DIY 24k mini split condenser for the 2 ton Universal condenser? I would plan to use the quick connect line set, but I would need instructions about the electric wiring if it is possible.

  22. Will you be doing a more comprehensive video of your Universal wifi thermostat? We recently purchased one for our Universal series heat pump but there are no clear instructions or videos on how it connects to the wifi. All we could find was a video for the thermostat for the mini-split systems. There was a set up video done that did not include or address the wifi connectivity and at the end of the video the presenter said that in the next video they would explain the wifi connectivity. Is that second video coming out soon? Currently our system will not connect as the basic instructions say that it will.

  23. I installed the 3 ton 36k universal series with High ESP air handler and so far we are loving it. I do have one question. When the thermostat calls for heat, the air handler starts up but it starts at a lower speed, after about 30 seconds the air handler ramps up to full speed. I read this is to allow the refrigerant to warm up and minimize blowing cold air from the vents. Is this correct operation or should the air handler be 100% power from the moment it kicks on?

  24. We built a 24′ by 24′ pole barn that I have made in to a mancave and want to put in a mini-split that both cools and heats. Do you all have a DIY system that does that?

  25. Is a universal series modular blower coming to pair with universal a coils for a downflow system? Or is retrofitting with signature series modular blowers the only option?

    1. Currently, the only option is to pair it with a Signature Series modular blower. There are currently no plans to make a Universal series modular blower.

  26. What are the CFM on this unit? I cannot find any information? Trying to design a system based on the mr cool 4ton universal heat pump.

  27. Is there a recommended location to drill an access port on the A-coil for installation of a UV sanitation light to deter mold and bacterial growth? If not, what is recommended to deter mold and bacterial growth?

  28. Is the new 5 ton Universal High-ESP Air Handler horizontal right position available yet and if so where can I find one.

      1. Other manufacturers have info out there on how to install horizontal on the right side . How come MRCOOL does not?
        Usually you swap a couple of brackets to the other side of the coil and flip the plates under the air foil . I see nothing like that on the Universal 4 to 5 ton air handler. Is there a kit for this or how is it done ?

  29. I’m looking to buy the mdui18024036 universal system set up for 3 ton with air handler. I’ve looked all over the spec sheets and manuals for information for the blower esp rating and the evaporator coil esp rating.
    This info is needed in order to have duct system designed for the unit. Can you please provide these details.
