 Mini Split Air Conditioner Heat Pump Sale

If you have any questions about Mini Split Systems, Central Air Conditioner Systems, Air Conditioner units in general or Air Conditioning Installation questions , then we've got the answers you need! We carry many brands like Midea, AirCon, YMGI, Daikin, Chigo, Mr Whisper, Cooper & Hunter, and  Goodman Air Conditioner which is now Daikin Air Conditioner. If you are shopping around online for a new Mini Split Air Conditioner, Mini Split Heat Pump, or Split AC System in general, you have probably come across an abundance of Ductless Air Conditioning models that claim to come with “everything you need to install the Split System.” An obvious component of any Split System Air Conditioning is going to be that conduit tube which holds the refrigerant lines. One of the aspects which may really have you wondering if you will really need that HVAC technician to come out are those often included “pre-charged” refrigerant lines. Manufacturers and distributers of Ductless Mini Split will often explain that the refrigerant lines are pre-charged with R-410A refrigerant, which may give the impression that the lines are good to go, or DIY. But it is erroneous to assume that the pre-charged line of your Mini Split Air Conditioning or Ductless Heating and Cooling will not require the tools and knowledge of a professional Minisplit and Heat Pump System technician. While the Heating and Cooling Units manufacturer or online dealer is (hopefully) not intentionally deceiving you, the idea of a “pre-charged” line may be a little misleading, as one of the main things your HVAC professional will be doing is “charging the line.” In fact, most of the Best Air Conditioner Units refrigerant lines that are installed by professional ac are, in fact, pre-charged with a quantity of refrigerant (typically, 13 to 16 feet).

Central Air Conditioner Heat Pump Sale
Although this is the typical amount of refrigerant added to many Mini Split Heat compressors, there really is no “typical” amount of refrigerant that will ensure proper functioning of a Mini Split Heat system. First off, remember that the line sets you receive with your Mini Split Heat won’t necessarily be the length of line set that you actually use for installation; one of the customizable attributes of Mini Split Heat air conditioning is the flexibility of where you will install the Mini Split Heat compressor, which can make the length of line used  quite variable. And there really isn’t a standard volume of refrigerant involved, only a set pressure, which can alsovary with conditions. So, regardless of what line set length you end up using, the amount of refrigerant will have to be regulated and checked to ensure the proper pressure settings. Therefore, the pre-charged line does not in any way ensure that you can hook up the copper line set and expect the equipment to operate properly. 

So, it is typical that an installer called to install a Mini Split Heat begins with a line set that has some quantity of refrigerant pre-loaded in the compressor. After the distance and configuration of the Mini Split Heat system is in place, the installer hooks up gauges to measure the current pressure within the lines. The installer than increases or decreases the amount of refrigerant in the lines, in order to attain a proper pressure reading, as incorrect pressures will result in poor performance or failure of your air conditioning system. This is generally not something you can do without proper training, regulations, and a license, as refrigerant leakage could pose a hazard to both you and your environment.

Another thing to recognize is that, typical refrigerant lines need to be vacuumed of any contamination that may have entered prior to charging. This is another handy trick of the HVAC trade; the technician has tools that allow him/her to quickly carry out this task, as well as monitor if anything has gone wrong.

Although some Mini Split Heat merchants may say that it is possible to install these “pre-charged” systems all by yourself, this is certainly not the preferable method, and Mini Split Heat generally require professional assistance for the tasks that have been mentioned here. Again, they are not lying…indeed, if you possess the tools and skills of an HVAC pro, you can certainly do it yourself.  The same can be said of an auto mechanic, a five-star chef, or a brain surgeon (provided you do not intend on operating on yourself!)  But there is nothing about “pre-charged” refrigerant lines that make installing a Mini Split Heat particularly more do-able.

Because these Mini Split are intended by the manufacturers to be professionally HVAC installed, you won’t find many (if any) warrantees that cover a Mini Split unit that you have attempted to install yourself. So, an added risk that you incur, even if you have trained yourself in HVAC and have access to all of the tools you may need, is that the Mini Split it self may arrive defective and you have no recourse. 

A truly do-it-yourself Mini Split would have to be designed with technology in mind that removes the need for vacuuming and ensures proper pressure on the lines. It would need to have self-regulating mechanisms in place to either self-solve problems that may arise, or avoid them altogether. To top it off, a truly DIY installed Mini Split would be promoted as such by the manufacturer directly, and would come equipped with a warrantee that honored the fact that this installation would be treated more like a plug-and-play, and would not require professional installation inorder to be honored in the case of a defect.

There is at least one Mini Split that has achieved true DIY installation status by addressing all of these pitfalls. The refrigerant line system of the Mini Split is vacuumed at the warehouse prior to charging, so no vacuuming required. Rather than “pre-charging the line,” the compressor is loaded with refrigerant and contained with specialized“quick-lock” connector fittings. Mean while, the line set is pre-attached to the indoor evaporator of the Mini Split. When the line is connected (by the user, not a technician) at the locked fitting of the condenser, the line is charged with refrigerant, and ready to go.

But, how is this different then apre-charged line?  Doesn’t the pressure of the line still need to be tested?  No, because the entire 25’ stainless steel line is charged with refrigerant. The stainless steel line set has the advantage over other Split Heat line sets in that it is less prone to leaks than the copper lines. So, because the entire line set will be filled with refrigerant, proper pressure within the lines is no longer anissue;  the downside to this is the limitation on how many feet of line set is available to set distance between the evaporator and compressor of the Split Heat.

Keep in mind that any Split Heat installation, even one that is DIY, HVAC-wise, is going to require some electrical know how. This is especially truein cases involving a Split Heat with a capacity greater than 24,000 BTU (or over “2 tons” of air conditioning capacity). So, just because you might get away without hiring an HVAC installer does not necessarily mean you won’t have to call the electrician.

So, although many manufacturers and online distributers may taut incredible ease of installation, and even sell kits to help you put your Mini Heating in on your own, it may not always be the best idea. Even if you can get away with the majority of the installation (i.e.: the drilling, mounting, and configuration) on your own, you will usually need an HVAC installer for the “dirty work” such as the electrical, and charging and gauging the refrigerant lines. For one, it maybe illegal to do so, as an open refrigerant line may pose a risk to you or the environment. Also, you may not be able to get customer support easily, should you encounter a problem. There is also the risk that if you encounter a problem  (or simply have a defective Mini Heating), you may void the warrantee on a machine not intended for DIY installation, if you attempt to install it on your own.

However, there is at least one Mini Heating on the market that has undergone some adaptations to the installation procedure, in order to introduce itself as a truly “install yourself” Mini Heating. The AmericAire
 ACEDIY 12HP110 air conditioner has all of the features that you would expect to find on a Mini Heating. The major differences are in the way that the lines are charged and the method by which they are hooked up. (So, keep in mind, any electrical configuration will still be up to you to hash out prior to installation. However, AmericAire has also minimized this task with a fairly standard 110 volt system.)

The AmericAire ACEDIY Mini Heating is the first truly “do-it-yourself,” self- installed Mini Heating. Everything that you need to install the Mini Heating is included. This includes the Mini Heating  indoor evaporator unit, the outdoor condenser, the wiring, a remote control, and a 25’“Quick Connect” flexible stainless steel refrigerant line set. The Mini Heating line also comes with enough R410A, the more environmentally friendly refrigerant, to charge your line. The refrigerant is built in to a fitting which will charge your line with 25 feet of refrigerant automatically, when the line is hooked up.

This is where the materials you receive with the AmericAire DIY Split Heating will be a little different than that of a standard Split Heating purchase. The line set of this Split Heating model is equipped with a special “push-and-lock”connector, which takes only seconds to hook up, and can be done easily and without a HVAC pro. The pre-vacuumedline is already connected to the indoor evaporator of the Split Heating, and will need to be connected to the locked fitting of the outdoor compressor. The “Plug-and-Go” fitting of the compressor then automatically charges the system with the necessary refrigerant, without the use of a vacuum pump, gauges, or refrigeration. The line will be completely charged with refrigerant, and should not need to be opened at any time, as it does notrequire pressure gauging. The line set of the AmericAire ACEDIY is stainless steel, rather than copper, to prevent anyleaks of refrigerant.  These specialized DIY features which have been incorporated into the AmericAire ACEDIY Split Heating line set allow complete home installation, without the need for HVAC tools, and can therefore save you the time and money involved in hiring a professional installer.

More About the AmericAire
ACEDIY12HP110 Mini Split:

The AmericAire Mini Split Unit is also very efficient with a SEER score of 20. The smooth operation of the inverter compressor accounts for this jump in efficiency from older models. This Seasonal Efficiency score is 4 points above the score of 16 which is required for tax rebates for more efficient appliances.

This new compressor in this Mini Split Unit by AmericAire also offers a wider operating range than former models, allowing the ductless heat pump atout door temperatures below zero. The ductless heat pump of this model can operate from temperatures as low as -5degrees Fahrenheit to temperatures as high as 109 degrees Fahrenheit. So this Mini Split Unit also may be an excellent choice if you are in a location that is prone to cold winters and snow, and will be relying on the ductless heat pump to keep you toasty through the holidays.

The features of the AmericAire
ACEDIY12HP110 model include:

Multi-Fold evaporator – Larger spaces in the evaporator provide advanced cooling and dehumidification.

Three Dimensional Swing Delivery – Allows air to flow in all directions, maximizing air circulation and comfort.

Sleep Mode Operation – Allow you to time your settings; add a few degrees  while you sleep or when you head off to work, saving valuable energy and related costs. Or, if the Mini Split Unit will be in a bedroom, have exact temperature and humidity settings for your comfort while you sleep.

Independent De-humidification – Removes moisture from the air when the temperature is just right and cooling is unnecessary.

On/Off Timer- Save energy by programming your Mini Split Unit to turn off automatically when not in use, and resume when the space will be occupied.

Intelligent Defrosting – Minimizes hesitation when you are ready to warm up the space, and reduce the risk of damage to your Mini Split Unit.

The AmericAire Mini Split Unit has a cooling capacity of 12,000 BTU. In other words, this is a “1 ton” Mini Split Unit.  This is quite a bit of capacity for asingle-zone Mini Split Unit, with an average cooling capacity of 600 square feet. This Mini Split Unit could likely cool an entire small studio apartment (with a somewhat open layout and good air flow.) This is more than enough air conditioning fora large master bedroom, bonus room, or finished attic.  The heating capacity of the ductless heat pump of this model is even larger, at 15,000 BTU. The Mini Split Unit runs on a 110 volt power supply, so it is unlikely that you will have to do much rewiring if you have standard outlets.

The Airflow rate of theAmericAire ACEDIY Mini Split System is 430 cubic feet per minute.  So, you can count on a reasonable amount ofair flow on the higher fan settings of this Mini Split System.

The dehumidification features of this Mini Split System are also very decent. The Mini Split System is capable of being set for dehumidification only (which can remove moisture from the air without affecting the temperature) and is capable of removing 2.8 Pt/hour.

The outdoor inverter compressor unit of the AmericAire Mini Split System is 38.6” wide, 26”in height, and 15.7” deep, and weighs 106 pounds. The indoor evaporator of the Mini Split System is 38.4”wide, 14.3” in height, and a mere 11” deep. It weighs 31 pounds.  Although this is not the most compact evaporator on the Mini Split System Markey, it is still a rather compact and unobtrusive wall unit. Just like most Mini Split System which require professional installation, the AmericAire Mini Split System operates without producing much noise, with an indoor noise level of 35 decibels.

You can install the AmericAire Split System compressor as far as 82’ away from its indoor evaporator. The maximum height distance for installation is 33’.

The piping connections for the DIY Split System include: ¼” piping for the liquid refrigerant, ½” piping for the return suction, and ½” piping for the drain. Again, all are included for installation when you purchase this DIY Split System.

The AmericAire
ACEDIY12HP110 Split System comes with many of the self-maintenance features you will find in modern, professionally installed Split System. The Split System incorporated and Auto-Restart function, which will resume your settings and your Split System functions in the event of a power outage. The outdoor coils also automatically defrost during frigid outdoor weather, preventing ice from accumulating on the heat coils.

This Split System Heat unit comes with a manufacturer’s warrantee that extends 5 years for the compressor,3 years for the circuit board, and one year for parts and labor.

So, it seems to keep coming up again and again, that electrical considerations must be made before embarking on any Split System Heat installation. Even in the case of a true DIY Split System Heat installation, it is a given that you must have both an appropriate source of power, and a designated circuit breaker in place before thinking about adding a Split System Heat appliance to your home. Be sureto contact city hall in order to find out about proper permitting for any electrical work you plan on doing yourself.

Before you purchase any make or model of Split System Heat, be sure that you are aware of the voltage requirements in the manufacturer’s specifications. Smaller capacity Split System Heat air conditioners may only require 110 volts, which may not require much modification to your home wiring, as standard outlets in which you plug your TV and other appliances, inthe United States, are typically 110 volts. However, expectanything over 12,000 BTU (1 ton of air conditioning capacity) to require 220 volts, which may require some electrical upgrade.

Split System Heat are most commonly hard wired directly from the electrical box. The outdoor condenser of the Split System Heat will generally be connected to the electrical fuse box through an outdoor disconnect box. The outdoor disconnect box is there for safety, and always a good idea to use when wiring Split System Heat. Local electrical safety code will dictate the proper distance between the outdoor disconnect box and the Split System Heat compressor/condenser. (Typically, the proximity will allow the power to be disconnected while standing at the compressor.)

Most electrical wiring of Split Unit air conditioners runs straight out from the back of the indoor air handler. Rather than plugging into the nearest electrical outlet, the electrical wiring of the evaporator will receive power from the condenser, via the conduit. The electrical wiring runs along side the refrigerant line set.

When wiring for a new Split Unit, always be sure to check the requirements for proper electrical wire gauging.

Another major thing to keep in mind is that the Split Unit needs to have a designated breaker in the electrical box. So, makesure there is room in the box for a dual pole circuit breaker that will be for the Split Unit air conditioner alone. The circuit break must also be of appropriate size for the Split Unit you have chosen. A dual pole 20 amp circuit breaker will be sufficient for most Split Unit systems with capacity of up to 24,000 BTU (2 ton Split Unit.)


Once you have completed installation of your Heat System air conditioning system, you can kick back and enjoy the comfort of custom-tailored temperature and humidity control in your indoor space. The icing on the cake is that, with a Heat System system, you have an air conditioning system that is barely detectable visually and does not disrupt your décor. No window unit blocking your view or the natural light, and no clunky appliance in the hallway. 

However, you may have found that the refrigerant line set may actually seem to be hanging awkwardly on its way to the outdoor compressor. If you are a stickler for stream line and tidy design (which might be why you opted for the Heat System system in the first place), it might be nagging at you that the project just doesn’t look “complete.”  Wouldn’t it be nice if the outdoor installation of your new Heat System looked at sleek and finished as the indoor project?

Well, there is actually a Heat System accessory product that is designed to do just that.  Slim Duct line set covers are customizable little ducts and fitting that are made with Heat System air conditioning systems in mind.  They run along the profile of your house carrying with them your line set, adding a niceand professionally finished touch, while also providing added protection toyour line set against the elements. Truth be told, that exposed line set is more than just an aesthetic concern;  over time, the taping on the line will deteriorate if left to the elements, exposing the line set and reducing the efficiency of your Heat System.

The ducts and fittings of Slim Duct systems are made from a high grade PVC material which resists UV radiation and other weather conditions which may wear away at your line, potentially causing damage or leaks. The superior construction will also potentially prevent damage from random elements, such as falling debris, vandalism, or pests. Additionally, SlimDuct Systems are flame retardant,
conforming to the requirements of UL-94-V-0.

No matter what model of Heat System you have, or what the exterior of your home looks like, SlimDuct most likely has an appropriate option to meet your needs.  The ducts and fittings of SlimDuct Heat System line set coverings come in 4 different sizes to accommodate either single or multiple line sets. The of SlimDuctsystem line also includes 26 different fittings, in order to accommodate all types and complexities of Heat System configurations  This can be very useful if you have multiple air handlers running to a single compressor, but also makes design very easy ifyou just have a single bit of line to be concealed. 

A SlimDuct Heat Unit line set duct system is easy to install. Simply secure the SlimDuct and fitting bases to the wall, install the line set and the drain hose, clip on the duct cover, and secure the fitting covers with the provided stainless steel screws (SUS 304 Stainless steel to prevent rust streaking). If you would prefer that your SlimDuct line set protection system be water proofed, an additional step would include sealing all longitudinal and lateral seams, screw heads, and points of wall penetration with a weather proof seal or putty (not included).

The 2m long pieces of SlimDuct duct have slotted knockouts provided at each 100 mm interval on the base. This facilitates easy attachment to the wall with provided SUS 304 stainless steel screws. The knockouts also provide an easy and customizable way to create an exit slot for the drain hose.

The SlimDuct components come in 5 neutral colors (white, ivory, gray, brown, and black) in order to suit the color scheme of most home. If you prefer an even more customized look,you can use any paint that is made for use on vinyl. You can match it to your exterior house paint, for a less noticeable “blend in” look. Or, you can choose a complimentary color, and use the Slim duct system toadd a little interest to your exterior.

Slim Ductline set covers have already been installed in residential and commercial applications throughout the globe, and have performed with excellent reliability.

The ducts and fittings are coated in a high grade finish. The SlimDuct line ducts for Heat Unit line sets are an excellent combination of function and style, adding aesthetic appeal to your air conditioning system, while also reducing maintenance and providing protection. Yet another way to get themost from your Heat Unit air conditioner, as well as prolong the life of your system.


One concern that you may encounter with your Heat - Mini Split, which can actually be quitean east fix, is an icy evaporator.  This problem is most commonly caused by a dirty filter.

The first thing you should do is eliminate the problem. Take the filters out of the evaporator unit of your Heat - Mini Split and clean or replace them. Some Heat - Mini Split utilize disposable filters, but many are meant to be cleaned and reused. Soak the filter in water or a low alkaline soap, swishing it around a little, but not scrubbing. Leave it to dry completely over night before returning the filter to the Heat - Mini Split air handler.

After you have eliminated the source of the problem, and have reinstalled clean filtration in your Heat - Mini Split, run the fan of your Heat - Mini Split unit on a high setting. No cooling mode, no heat mode, only the fan. The purpose of this is to heat up your system to melt the ice, and to get some air circulating to dry off the evaporator.

And that’s it.  After all the ice has melted, the unit should resume proper function. If the problem recurs very quickly, you might consider calling in an HVAC technician to further assess the problem.




If you have been browsing around for a new Heating - Mini Split air conditioner, or looking for an efficient method of ductless home cooling and/or heating, you have probably already been introduced tothe reverse valve and the mini split heat pump. Mini Split heat pumps are a ductless form of heating that some Heating - Mini Split, equipped with are verse valve, can use to  provide heat in addition to cooling and dehumidification.
The two forms of truly ductless heating are electrical heat, and ductless heat pumps. Although many, in the United States in particular, are far more familiar with the concepts behind electrical heat, heat provided by ductless heat pumps offers some real advantages. They are more efficient, do not add much tothe cost of a Heating - Mini Split unit, and  do not cost anything to install if you are already installing ductless cooling. With energy efficiency concerns and Heating - Mini Split sales on the rise, it is likely that we all might become more familiar with this form of ductless heating in the future.

A Heating - Mini Split that also “includes a ductless heat pump” simply means that the Heating - Mini Split is equipped with a reverse valve which can trigger the refrigerant cycle to work in the same way it does to cool, except backwards.  Because, a Heating - Mini Split is actually already a “ductless heat pump”, it is just generally absorbing the  heat from indoors and pumping it out, to keep your inside spaces cool (free of heat) throughout the summer time. Reverse this process, and the Heating - Mini Split begins gathering the ambient warmth of the outdoor compressor, and pumping it back in. That is really the only difference between a Heating - Mini Split with “cooling only” functionality, and Heating - Mini Split “with a heat pump”:  the reverse valve.

And it just so happens that, with all of the efficiency that today’s Heating System have to brag about, ductless heat pumps can do the same. Heat pumps are actually a far more efficient and energy conscious way to warm an interior space than electrical heating, which often requires more power for even less output. The ductless heat pump function (of Heating System that have them) benefits from all of the same technology that makes Heating System such efficient coolers, and the efficiency during heating seasons turns out to be very similar to that of cooling.

Ductless heat pumps are a much more passive way to heat a home than to warm it up with electricity like a toaster. Rather, it exploits the same mechanics and chemistry that air conditioning does;  power is used to move refrigerant along a track, and to power the blowers which circulate the air modified by the het-absorbing liquid refrigerant.

If you are already planning on installing a Heating System, there are no added expenses(other than purchasing a slightly more expensive unit which incorporates are verse valve) to add the functionality of a ductless heat pump to a space that will ever require heating. This makes a Heating System with heat pump a great solution for a room addition or bonus room which requires both heating and cooling.

The only real disadvantage of a ductless heat pump has, which is not an issue with electrical heat, is their inability of some of the older models to easily function at very cool temperatures. At around 19 degrees Fahrenheit, the operation of a ductless heat pump usually starts to dissipate. When a condenseris exposed to very cold outdoor temperatures, the refrigeration in the compressor can freeze. Because the heat pump works by gathering the ambient heat around the compressor, this presented a problem for ductless heat pumps. So, in very, very cold climates, Heating System with ductless heat pumps have not always provided an ideal solution for interior warmth. However, some people still managed to get around this weakness of ductless heat pumps, by utilizing supplementary warming devices (such as crank case heaters) in order to keep their compressors warm during the colder months.

Many of the newer Heating System on the market have resolved this problem with advanced inverter technology, etc., which have brought the minimal operational temperature of their heat pumps down, significantly. The average seems to be around 5 degrees;  although the ductless heat pumps on Mitsubishi Heating System can operate at as low as -13 Farenhiet. With the addition of ductless heat pumps, Heating System technology seems to be well on its way to providing us with year-round, efficient comfort.
