Overview

MrCool Universal Heat Pump Continues to Heat in Temperatures As Low As -22

So what is it that makes the 2 to 3 Ton 20 SEER MrCool Universal Central Heat Pump Split System so very special? As we mentioned, the key is the sophisticated DC inverter compressor and intelligent internal control system. The ability to operate at reduced capacity for long periods saves serious money. Likewise, the ability to scale up performance as the outside temperature fluctuates delivers significant versatility. That's why the Universal can deliver 100% cooling capacity at temperatures as high as 110 degrees Fahrenheit, 100% heating performance at minus 5 degrees, and continue producing heat down to minus 22.

Serious performance capability isn't the only thing the 2 to 3 Ton 20 SEER MrCool Universal Central Heat Pump Split System comes with. The condenser features an auto-reset internal overload protector, direct drive fan motor, inner groove copper tube-aluminum fin, gold fin corrosion protection, automatic defrost, electronic expansion valve, and a condenser with both a compact footprint and a shallow profile. The air handler comes with electric box assembly, fan motor, secondary drain pan, primary drain pan, and the capacity to accommodate an auxiliary heat kit.

No-Vac Quick Connect Line Set Compatible!

One of the most exciting aspects of the 2 to 3 Ton 20 SEER MrCool Universal Central Heat Pump Split System is the MrCool No-Vac Quick Connect Line Set. This unique line is kink resistant, precharged with R410a refrigerant, and uses Quick Connect fittings. These specialized fittings mean that installing the Universal Split System with a No-Vac Quick Connect Line Set can be performed without specialized tools. Basically, the No-Vac lines simply plug into the condenser and air handler. No cutting, no brazing, no vacuuming, and no charging is required. It reduces hours of installation work down to minutes.

Q & A

Do you have questions about this product?

Is it all filled with refrigerant indoor, outdoor and line set? Do I still need a tech to install it?

I see it says 2 to 3 ton. Which is it?

Do you offer a down flow air handler that uses the no vac line set for use with the heat pump condenser model MDUO18024036?

Is the blower a multi speed x-13 style motor or is it a true variable speed motor that modulates with the load demand?

What type of scenario/condition would require this unit to have a heat strip? I see them touting it working at sub zero temperatures but cannot find any info about when heat strips are needed or used. Thanks!

When you say the condenser is non-communicating what do you mean? According to manual on page 20 it shows R/C going to thermostat as power supply? Will this not cause issues if the air handler is also pushing power supply to thermostat for R and C? Also the condenser shows W1 is heat control signal as it is communications defrost mode?

Second question - you answered in QA that 3 ton unit has a CFM1000? Shouldn't a 3 ton unit have a minimum CFM 1200 and on most heat pumps run around 1350?

What are the dimensions of the air handler? And does the duck work exit at the top of the unit or the back or is there an option for either? I'm looking at this setup I would guess the up-flow answers the duck work exit.

How many CFM's is the air handler at the 2ton setting? How many CFMs at the 3 ton setting?

How many watts does this system pull?

How do you choose between 2 or 3 ton when current system is 2.5?

Is the "oil return bend" shown on P 15 of the condenser manual required for the now vac quick connect linesets?

Outdoor installation manual on page 25 - Electrical connection, is stated: Breaker = 29 Amps and Fuse size=50 Amps.
What should be my "circuit breaker" ? 30 amps or 50 amps?

Indoor installation manual on page 17 is stated : Max Over current protector=15 Amps , is that means my Circuit breaker should be 15 Amps ?

Thank you.

I have a 1700 square foot area. The specifications show this bundle has a coverage area of 1250 to 1500 square feet. Shouldn't this unit set to a 3 ton unit provide coverage around 1800 square feet?

Is the air filter a MERV 13+ filter or a HEPA filter?

Do these units use an electronic TXV valve?

How well would this unit cool in central forida?
Install looks simple enough, but i've not seen such a small condenser on a three ton.

Is the MrCool Universal Flare to Sweat Lineset Installation Kit, P/N: HA20952, required for a traditional brazed Lineset Installation?

Purchasing the 2 to 3 Ton 20 SEER Variable Speed MrCool Universal Central Heat Pump Split System - Upflow/Horizontal along with the pre-charged lines online from Ingram's and installed myself, as the home owner not a contractor, will the single family warranty be valid? Somewhere I did read that MrCool will not warranty their systems purchased online, does that apply to this system?

Hi,

The 2 1/2-ton and 3-ton units both are 18 SEER? How does this work? Are the prices the same? How much and how long it'll take to ship to PA 19460 area?

Thank you.

Sam

Trying to plan out a replacement system for a propane furnace. I am buying a new air cleaner, too. Would a 20x20 work? Also, what is the maximum CFM of the air handler?

Hi! This is the wave of the future right here. Do you anticipate a 5-ton offering as well? If so, any idea when? Thanks!

How much does the air handler and the condenser weights?

Well this unit work in the north part of Montana where it gets to 80 below zero for a week or better

i am looking for a 3 ton unit ,after all is this unit 3 ton?
and i want a really quiet unit , how loud is the noise of this unit?

Does this unit cool to -22 as well? I need low ambient cooling.

Will this unit be ok install in Lancaster Pa.17552 area ? What is recommendation unit for 1600 sq home only 1st floor 3bedroom and 10 ft ceiling and full basement.looking to replace my gas furnace and ac unit maybe going with gas unit again or electricty unit.Thank you

I NEED 3TON SPLIT SYSTEM HEAT PUMP. HOW LONG IT WOULD TAKE YOU TO DELIVER TO NYC

I don't have Gas only electric does the system come in electric-only and not natural gas?

I was wondering why the outdoor unit needs such a large breaker? I currently have a 2-ton unit (very old) that is properly wired with a 30amp circuit, why does this require such a large circuit? Is it not the soft-start DC inverter style compressor that most mini-splits use? Also what is the maximum pre-charged line length available? thanks.

Is this model (MDU18024036) a 4th generation Mr McCool?

I want to swap out my 14 year old Bryant Unit with this one, can I use the current Line Set that is in place rather than the pre-vac lineset?

Why would one elect to choose a "conventional" installation instead of using the pre-charged lines?

What is the difference between this unit and the MDUCO18024036?

Is it possible to set it to 2.5 ton?

What round flex air intake size is needed for 2 ton and 3 ton operation?

Will this unit control humidity, not just read humidity, control it?

How long does it take the heat pump to start blowing out warm air

Hi
How long is the shipping to 33774

Can you recommend any downflow air handlers that are sized appropriately for the MDUO18024036 condenser? Do you know if the manufacturer has plans to release an air handler of their own that will work for downflow applications?

Does this unit have to be hooked up to a complete set of duct work both return and supply?

1. I am replacing an old 80k furnace with this air handler. Existing supply and return ducting is 14" flexible - is this adequate for the cfm of this unit, especially in cooling mode?

2. I would like to zone the system (two zones) without using a bypass damper (relying on the variable speed motor to adjust the air volume). Do you sell a zone panel/motorized dampers/thermostats that would accomplish this? Please advise what I need for a two zone system (each zone is approximately 700 sq. ft.)

3. Is there a knock down plenum you sell for this air handler installed in upflow/vertical configuration?

Thanks

How do I source parts for this unit?

Does the fan run nonstop? I might need some advice on how to wire thermostat, unit seems to heat fine but then when it reaches temp the fan continues to run and blows cold as because the outside condenser is not running. Any help would be appreciated.

can the unit be converted to a down flow for use under a house using the old duct work.

So as I was reading through the questions that have already been asked I was interested in a little more detail to this question:
The question was asked about the AHU needing to be 8' above ground level because they wanted to install in crawlspace. The answer was if coil is even with or below level of condenser then an oil control bend is needed. So please confirm this can be installed in a crawlspace with ahu below grade with the oil control bend and can this be done with the precharged flexible line sets? The detail in the installation booklet is very vague in this instance for precharged line sets. Is there a better detail?

Your Answer:
BEST ANSWER: Yes that is correct- the air handler can be installed below the condenser with an oil control loop. It is not easy to bend the pre charged line but it can be done. It would be best to have an experienced installer handle that part.

My question is this:
In the Installation Manual/Owner’s Manual for the Universal Series DC Inverter / Condenser MDUO18024036 at the bottom of page 14 it states
“For installation with a No-Vac Quick Connect Line Set, refer to the next section starting on page 23”
Page 23 mentions nothing about a bend in the line but on page 24 where it states:
"If the outdoor unit is located on a level higher than the indoor unit" it refers to Fig. 2.22 that shows a Non-return bend. I would like to verify that in this situation that the "Non-Return Bend" is the only extra bend needed and if that is correct is there a diagram that shows the dimensions that the bend should follow as they are described on page 15 when using a "Conventional Line Set Installation". Sorry for the long question but looking for some clarification.

When in defrost does the heating element come on so not to blow cold air?

What is the coldest any of your units can handle? I live in northern Minnesota, it can get nearly 60 below wind chill here some winters. I am looking for a whole house application and also a garage application.

Do you have a wall mounting bracket that can be used on wood framing to support the outdoor unit?

When will the Mr Cool Universal A Coil be available from IWAE? Or anywhere?

Can You install 2 of the 2-3ton universal condensers back to back with 24'' Between them, looks as if that's possible in instructions. Just want to make sure

How is the main blower cabinet plumed into to replace an existing system? In other words, what size return air box is needed?

Or can the cabinet take right-angle return air?

I am wanting to replace an aging propane furnace that is in my garage, Can I simply remove the old furnace and replace with this. Will this hook up to my ducting? And, how many square feet home will this service?

I bought 2 Mr Cool Universal 2-3 ton heat pumps from Ingrams. The are installed without aux heat strip. In settings 0170, should I choose (2) single-stage heat pump (no auxiliary heat) I ask since currently that is the setting but the unit does not seem to ramp up when demand is higher, especially in the cooling mode. Thanks

How can this qualify for a tax credit since it does not have an Energy Star rating nor is it listed at energystar.gov website?

on mr cools site they show a 10kw backup heat do you sell that one also. I have a rudd 3 ton with a 14kw back up

Thanks

What is the cost of i 3 ton nstallation? What is the SEER rating?

I have a 30amp no fuseable connection running to old outdoor trane ac condenser will this power the condenser for this unit? 15amp for blower and 30 Amp to run condenser?

Can the Universal air handlers be easily disassembled to fit into a small attic entrance with limited height space and then reassembled once in the attic where there is more room for the horizontal installation ? If so where is there a schematic available for the unit ?

Is it possible to add a ductless head unit to a 2 to 3 Ton 20 SEER Variable Speed MrCool System package so that one isolated room in the basement could have its own thermostat? The rest of the house is ducted and would be well served by the air handler.

How big a home will this heat in the Northeast? I have a 30 year old two story, 1350 square foot, townhouse originally built with and ducted with a single zone, outdoor heat pump with indoor air handler. Is a two speed air handler available also?

can I get a standard line set for the Mr Cool MDU18036. I prefer not to buy the precharged one they suggest on your web site

Do you offer veteran discount?

My current plenum is 3" too deep on the return side of the air handler. How can I make up this gap without having to create a new plenum? Thanks.

I am looking at this unit and have a nest thermostat that is connected for heat to my navien tankless heat system and to my current central air conditioner. I wish to use this unit only to cool. Can I eliminate hooking the heat thermostat wire to both the exchange and outdoor unit? I would cover this unit during the winter months. Thanks

Do I need to have 220 Volts in the attic for the attic HVAC unit, my current system uses 110volts.?
Thank you

The installation instructions for the air handler state that if the air handler is used in a horizontal configuration that the height between the air handler and the ground is above 8 feet. My existing unit is in a crawl space and there is only about three feet of space. Why is the eight feet needed for this unit?

What additional items would need to be purchased for a "forced air" heat/ac setup (not including ductwork) in a new construction house ?

I am awaiting a downnflow model which I see will probably be available this year. Do you know what the maximum length of precharded lines that can be run on the down flow? The lines for my install will need to take a few 90 degree bends as they go through the attic to compressor outdoors. Does every bend count as a certain number of feet when calculating the length ? Thank you

What temperature should the suction line be running at in heat mode? My old Goodman unit would get up to about 140F on a 40 degree day, but I'm finding this unit can get upwards of 175F-190F right at the air handler. Is this too hot or is this within the design of the system?

Is the air handler variable speed?

Do you have a down flow for mobile homes ?

I plan to buy 2 of these packages so that I can zone my upstairs and my downstairs separately. Both my upstairs and my downstairs are about 1000 square feet each and I live in North PA (zone 4). Is the 2 ton setting better for each system or the 3 ton?

Is this a sealed combustion unit?

Question by: James Reed on Dec 30, 2022 10:16:00 AM

Best Answer: Thank you for your question about the HA20919 MDU18024036 2 to 3 Ton 20 SEER MrCool Universal Central Heat Pump Split System.

I'm sorry to say that this particular unit is not a sealed combustion unit. However, we do have a range of sealed combustion units available that may suit your needs. Our knowledgeable sales and technician team would be happy to discuss your options with you and help you find the best solution for your home.

To answer your question about sealed combustion units, these types of units are designed to safely vent combustion gases outside of the home. This is achieved by separating the combustion process from the indoor air, ensuring that the air inside your home remains clean and healthy.

There are a few key features that make a unit a sealed combustion unit. Firstly, the unit must have a direct vent system, which means that it draws in outdoor air for combustion and exhausts the gases back outside. Secondly, the unit must have a sealed combustion chamber, which prevents the exchange of air between the combustion process and the indoor air.

The HA20919 MDU18024036 2 to 3 Ton 20 SEER MrCool Universal Central Heat Pump Split System - Upflow/Horizontal does not have these features, which is why it is not classified as a sealed combustion unit. Please don't hesitate to call us with any further questions or concerns. We are always willing to listen, learn, and help with any issues you may have.

Two questions please;
1. Can this cool 1590 sq ft in orlando. I am a little concerned about the 1000 cpm. What is the cpm on the 4-5 ton unit?
2. This will be a regular vertical install with the air handler about 2 feet off the floor in a closet. The compressor will be on a pad outside at ground level. The line set however, will go up thru the attic and down the side of the house to the compressor. Is there any special thing that needs to be done?
Thank you.

Can I replace a 4 ton Carrier Unit that is about 11 years old,
My system is a Heat pump with gas backup. The Heat pump works great until it gets below freezing then the gas comes on and just had to pay 480.00 for about a month and half on top of another 120,electric bill.
Gas is now 2.90 a gallon.
I have a cape cod house 1800 square feet with one bed upstairs and a loft with vaulted ceiling.
Just would like to explore some options.

If the air handler is installed with an electric heat kit, how does the air handler know when to turn on the electric heat strip?

Example situation: -15 F degrees outside for 24 hours or more. Heat pump has been running for 30 minutes, but temperature set point is not achieved (leaving air temperature from the air handler is not high enough) => air handler will turn on the electric heat strip.

My example is based on how long the heat pump has been running and the air handler leaving air temperature. Are those data points what are used by the air handler for it to decide when to turn on the electric heat strip?

Does the air handler fan stop during defrost on a MrCool Universal unit that does not have a heat strip installed?

Can this air handler(MDUI18024036) be installed on it's side?

For the 3 ton model, what is the maximum recommended quick-connect line set length? My preferred ACCU location may require a distance over around 80 feet and was considering a 50+35 with coupler setup.

Can an additional Wall Mounted Air Handler be added/integrated to this system? I have 1 room that I cannot reach with ductwork.

Is the changeover valve in a MrCool Universal system energized in the heat or cool mode?

The online manual and the manual that ships with the system show different thermostat wiring diagrams.
Can you supply a correct wiring diagram for a 2/3 ton complete thermostat wiring diagram without a heat strip?

We are looking at this system for an addition of about 700 sq ft, a hallway 2 bedrooms and a large bathroom. Is this the right size unit? What kind of ducting will we need to run?

What does the air handler do during a defrost cycle? My current heat pump will turn on the backup heat strips and keep the fan running to still provide heat. If the accessory heat strips are added to the mr cool universal air handler will it operate in a similar manner? I have an independent backup heat source so I would never need the heat strips for backup heat.

does heat strip require a separate breaker?

Does the MDUO24036 condenser come with enough refrigerant to support a 35' quick connect lineset?

Hi, I live in Miami. Do you guys do installation?

What is the recommended setting for cycling the compressor per hour on Heat? In my Honeywell T10 thermostat, by default it turns the compressor 3 times per hour, e.g. 10 minutes on, 10 minutes off. Thermostat maintains the indoor temperature within the 0.7℉ of the set temp. Would this type of frequent cycling of the compressor hurt anything?

T10 thermostat allows to configure less frequent cycling (range of 1-12 cycles per hour).

Background: I've got the outdoor unit configured as 24k BTU, and air handler at 2-Ton Medium Fan speed.
It appears as though compressor never reaches the max BTU output before the T10 thermostat temperature is satisfied and gets cut off. I am monitoring the power consumption using CT clamps and can see that compressor gradually (over the course of 6-8 minutes) increases its frequency and power consumption and reaches about 1260W (based on submittals at 50℉ outdoor ambient temperature the max BTU output is 26kBTU at 1950Watt), which corresponds to roughly 65% of the max BTU capacity.

So question is - would such frequent cycling of the compressor hurt it?

What Mr. Cool Heat Pump should I consider using if I will be replacing a 3.5 ton system?

Does this qualify for the 30 percent tax credit?

I currently have a 5 ton Rheem 410A condenser outside with a matching 5 ton air handler in the garage with a 5K heat strip. I would like to replace the outside condenser unit with a 5 ton MR Cool Heat pump as shown in the video that heats at -24 deg. F. I live in central Florida on the east coast near Cocoa Beach but 5 miles inland form the ocean so the salt air won't degrade the condenser coils as living closer to the beach would have done. It seems my reversing valve isn't working well, and instead of spending up to $1000 on its replacement I would rather invest that money into a new unit, unless you also sell reversing valves reasonably (and is it really hard to replace it myself? Would I need to vacuum the lines? ). I like the precharged lines but would have a very hard time pulling out the old lines and would like to utilize them instead. Is that possible? I know I would have to vacuum out the lines and shut off the valve at the compressor side to retain the 410A Freon. I also have spare 410A also, in case I need to put in extra after everything is brazed together. AS long as the compressor comes precharged I believe I'll do well.

Does the Universal MR. Cool come in a 5 ton? What is the SEER ratings for it and the prices? Does it use a Reversing Valve? I didn't see it in the pictures provided for the 4-5 Ton unit.

By the way I was very impressed with the video and the performance of the Heat Pump at such low temperatures. Great job on the design of the system even without the heat strip in the Air Handler.

Thanks for your efforts in a speedy reply and Merry Christmas to all of you. I love how you help the home owner with the DIY approach.

Do you need to install ductwork for this system

Does this system need it's own separate dehumidifier? I live in a very humid high dew point environment.

I am interested on MrCOOL do it yourself split heat pump. The line is approximately 35ft but it may not be enough for loops. The 50ft is too long but 40ft is ideal. Do you have 40ft line? If not, can 25ft and15ft be connected together? Please advise and God bless

I know dip switches 1 & 2 make the each unit be either 2 or 3 ton. What are dip switches 3 and 4 for on both the air handler and condenser? Do they make it 1.5 or 2.5 ton? Asking because the specifications tab on the listing shows more than just 2 & 3 ton capacities.

How do you change the units to be the other ton settings?

Per the Specifications tab on this listing:
Bundle Cooling Capacity is 2 Ton, 2.5 Ton, 3 Ton
Cooling Capacity on MDUO18024036 (condenser) is 1.5 Ton, 2 Ton, 2.5 Ton, 3 Ton
Cooling Capacity on MDUI18024036 (air handler) is 2 Ton, 2.5 Ton, 3 Ton

Best Answer: Thank you for your inquiry about the TXV valves for the HA20919 MDU18024036 2 to 3 Ton 20 SEER MrCool Universal Central Heat Pump Split System - Upflow/Horizontal.

TXV valves are not required for all coils in general, but some systems may require them for optimal performance. When a system does not require a TXV valve, orifice pistons are commonly used. An orifice piston is a device that changes the size of an orifice opening to control the flow of a refrigerant. An adjustable valve controls the orifice opening, which can be adjusted to ensure that the system operates efficiently. To provide the most accurate control of the system's refrigerant flow, the piston is typically used in conjunction with a thermostatic expansion valve (TXV).

The piston is linked to a sensing bulb, which detects evaporator pressure and adjusts the orifice size accordingly. Mechanical TXV (thermostatic expansion valve) valves use a thermal bulb that senses temperature and is connected to a valve that opens or closes based on the temperature of the refrigerant. Electronic TXV valves use an electronic sensor instead of a thermal bulb to control the valve. In some cases, an electronic TXV valve can be more accurate than a mechanical TXV valve, as it can respond more quickly to changes in temperature. Additionally, an electronic TXV valve can be more energy-efficient, as it does not require the use of a thermal bulb.

The good news is that the system comes with a mechanical expansion valve that is specifically designed to work with it. We hope this information is helpful and we look forward to assisting with your next home project. For any further questions or inquiries, please contact our sales and technical team at 270-575-9595.

I Have This Question Too (0)

I own two 2 to 3 Ton 20 SEER MrCool Universal Central Heat Pump Split System - Upflow/Horizontal units. One is functioning normally (it seems) and the other has an 'H4' reading, and seems to be running inefficiently. It's having trouble keeping up to the thermostat.
What advice can you give to me?

Sincerely,

Frederick Connelly

What does 2 to 3 ton mean?

What steps need taken to convert this air handler from upflow to horizontal? I don't see it in the installation guide.

at what temp does the heat pump stop working

Can the air handler be configured for horizontal flow to the right? As the drain pans are configured from the factory vertical up and horizontal left flow are possible.
Horizontal right flow would require moving the drain pan from one side of the AH to the opposite side. The location of the black drain plugs in the cabinet seem to indicate that horizontal right flow is possible but there is nothing in the installation manual that describes this. I've also read all the questions here and don't see where this is mentioned.

Can a propane furnace be added to this unit ?
