Not only does it work amazingly well, but it also serves as an excellent supplement to my furnace. The delivery was prompt, and the unit arrived in perfect condition.

Installation was relatively easy, although it does require some basic knowledge and skills, as well as the necessary tools. Being a handyman, I had no issues installing it myself and had it up and running within two hours. It's worth noting that contrary to what some may claim, it is essential to put a vacuum on the system before opening the valves, as stated in the instructions. This step ensures optimal performance and longevity.

The 18k BTU unit effectively moves air both vertically and horizontally, resulting in even cooling throughout the room. One of the standout features of this unit is its economic efficiency, making it a cost-effective replacement for a standard central HVAC system.

I did have my HVAC professional assist with the installation, and we encountered a glitch in the manual and video regarding the vacuum pump. The vacuum ports didn't fit a regular vacuum hose line, and the specialized fittings required were quite expensive. However, we decided to bypass this step and proceeded with the installation. To my surprise, the unit has been keeping our room cool even in scorching temperatures ranging from 95 to 100 degrees Fahrenheit. It has consistently maintained a comfortable temperature of 73 degrees, and I am impressed with its quiet operation.

Furthermore, I performed a "litmus" test and set the unit to its lowest setting of 60 degrees. It successfully blew out cold air at around 55 degrees, which is a testament to its cooling capabilities. Overall, it has been running smoothly for the past four weeks, and I am pleased with its performance.

In my search for a higher-quality mini-split, I stumbled upon this unit with impressive specifications and a suitable size. I replaced my old mini-split in the garage due to coolant leakage, and this unit has proven to be a worthy investment. The installation process was hassle-free, thanks to the comprehensive package that included hoses, wiring, mounting brackets, and clear instructions. Since I was replacing an existing unit, the hole was already in place, making the installation even easier. The hoses fit perfectly, and the connection to the outside unit was seamless. Wiring was a breeze, and I appreciated the convenience of pre-existing outside connections.

In terms of performance, this unit excels. It cools the garage efficiently and maintains the desired temperature without any issues. I particularly appreciate how quiet it operates, providing a comfortable environment without unnecessary noise. The remote control is a handy feature, allowing me to adjust the temperature and modes from a reasonable distance.

Another notable advantage is the significantly reduced noise level of the outside unit compared to my previous one. Even my neighbors have commented on the improvement. Additionally, I highly recommend testing the connections with soap water to check for bubbles, as this can help identify any loose fittings. I encountered one such fitting, but the soap water test made it easy to rectify.

As a seasoned HVAC technician with over 15 years of experience, I recently decided to purchase two units of the 20 SEER heat pumps for my own home. There were several reasons that led me to choose these units, including the excellent price, positive reviews, and the convenience of having them delivered directly to my doorstep. Now that the units are up and running, I wanted to share my insights and observations to help others make an informed decision.

Firstly, I must commend the delivery service. All four units arrived three days earlier than expected and were in great condition thanks to the reliable shipping provided by FedEx.

When it comes to installation, it is important to note that professional installation is required. However, the process is relatively straightforward, especially for those familiar with HVAC systems. The instructions provided are clear, although I did encounter some confusion regarding the clearances from walls and ceilings. The template differed slightly from the instructions, but with a bit of effort, I was able to figure it out. Additionally, it is worth mentioning that the indoor units were holding pressure when I removed the caps, indicating that they were free from leaks during their journey from China. The outdoor units already contained refrigerant, and the installation involved connecting them with the pre-flared pipes. I inspected the flares, and they appeared to be in good condition. It is crucial to pressure test and apply soap bubbles to the fittings, as well as pull a deep vacuum on the lines before releasing the refrigerant. Some individuals have chosen to install a sight glass and filter/drier, but these are not necessary for ductless systems. However, if you do opt for these additions, ensure that they are bolted in rather than brazed. Additionally, it is essential to wrap all the refrigerant piping and connections with the included foam. Leaving any exposed piping can result in condensation and water leakage within your walls or attic.

Regarding drainage, it is important to note that the provided drain tube is only approximately 7 feet long, while the line sets and wiring extend over 14 feet. Therefore, if you plan to install the units on the second floor, you will need to extend the drain line. I personally inserted the drain tube into a 3/4 inch PVC pipe and exited the house that way, which was not a significant obstacle. The electrical circuit requirements should be determined by a licensed electrician. Prior to the units' arrival, I attempted to find specific information about my units but could only find general amp and wattage ratings. To ensure accurate information, I recommend reading the data plate on the heat pump once it is unboxed and in your possession. This plate will provide you with the necessary details, such as volts, maximum and minimum circuit ampacities, and fuse requirements.

When mounting the indoor units, it is recommended to tilt them slightly in the direction of the drain tube exit to prevent water from accumulating in the condensate pan and developing mildew and slime. The cardboard templates provided are crucial for marking the holes during installation, but it is important to note that they may not be perfectly square on the cardboard itself. To ensure accuracy, utilize the printed part of the template rather than relying on the edges of the cardboard.

In terms of operation, I must say that I am thoroughly impressed. These units are remarkably quiet and perform exceptionally well. Having worked on various brands throughout my career, I can confidently state that these heat pumps are among the quietest I have encountered. They are comparable to other major brands that are significantly more expensive. After the installation, our two large bedrooms and bathroom on the upper floor cooled down rapidly and maintained a comfortable temperature while only drawing 1.9 amps at 120 volts, which equates to a mere 228 watts. The units' Wi-Fi connectivity and accompanying app are included, although I have not personally connected my units to the internet, so I cannot comment on their functionality. It is worth noting that other brands often require the purchase of additional accessories for such features.

As for the longevity of these units, only time will tell. However, I feel confident in my ability to handle any necessary repairs, and I also purchased two complete identical units to use as spare parts in case one needs to be replaced. This approach ensures that it remains economically feasible for me.

While I cannot speak to the effectiveness of the tech support provided by the manufacturer, I did receive an email from the seller assuring me that their team is available to assist with any inquiries or issues.

I recently purchased the 12000 BTU Rovsun unit and I must say, I am extremely satisfied with my purchase. The delivery was prompt and the installation process was a breeze, with no complications whatsoever. Once installed, I was pleasantly surprised by its heating ability and efficiency.

Living in Vermont, where temperatures can get quite chilly during the fall months, I was able to comfortably heat an area of about 900 square feet to temperatures in the upper 70s. What impressed me even more was the minimal impact on my power usage. Despite running the unit consistently, I noticed hardly any difference in my day-to-day power consumption. This just goes to show how energy-efficient this unit truly is.

In fact, I am so impressed with its performance that I have decided to purchase more units to heat other areas of my home before winter arrives. The benefits of using heat pumps to heat and cool your home cannot be overstated. Not only are they highly efficient, but they also offer significant cost savings in the long run.

Now, in the spirit of providing a comprehensive review, I must mention that there were two very small dents on the outdoor unit due to shipping. However, these dents were so minuscule that they were practically unnoticeable to anyone who looked at the unit. Therefore, I would not consider this to be a significant drawback in any way.

During the installation process, it is important to note that you will need to purchase a vacuum pump. I personally bought one on Amazon for around $125, which proved to be a worthwhile investment. It allowed me to complete the installation myself, saving me the expense of hiring an HVAC technician.

Speaking of expenses, the cost of this particular unit is outstanding. After conducting extensive research, I can confidently say that this unit offers the best value for its ratings. The quality and performance of the Rovsun unit are truly exceptional.

I should also mention that I did not have the need to contact tech support, as the installation process was straightforward and flawless. It took me approximately four hours, including the time it took to build a platform for the unit. Therefore, I cannot provide a rating for their support services.

I highly recommend the Rovsun 12000 BTU unit to anyone in search of an efficient and reliable heating solution. With its impressive performance, minimal power usage, and outstanding durability, it truly deserves a 5+ star rating. Thank you, Rovsun, for providing such a great product!

I recently purchased a mini split air conditioner and have been extremely pleased with its performance. Compared to my central air conditioner, this mini split is much more efficient and cost-effective. However, there are a few minor drawbacks that I would like to mention.

One aspect that I am not fond of is the filter. It is quite porous, which means it will require regular cleaning to maintain optimal performance. Unlike my central air conditioner, which uses high-quality filters that I have never had to clean in over 15 years of ownership. Additionally, the 90-degree bend in the copper line can deform if bent multiple times, so it's important to have a proper bender on hand.

Once the desired temperature is reached, the fan continues to run at a low speed, which can be a bit annoying. This constant running may also shorten the lifespan of the motor. It would be beneficial if there was an option to turn off the fan completely once the set temperature is achieved.

During the installation process, I opted to use a 25ft line set and saved a 16ft line set for a future unit. I personally dislike flare connections and prefer compression connections for better leak prevention. It would be great if the manufacturer considered offering compression connections as an alternative.

One tip I have is to ensure that the drain line is dropped straight down outside to prevent water and debris from getting trapped in the ribs, which can lead to clogging.

When it comes to energy efficiency, this mini split performs exceptionally well. I primarily use it for heating, and it consumes significantly less electricity compared to my 2.5-ton central air conditioner. In just four hours, I have used approximately 1.7 kWh, resulting in savings of less than $0.75. This translates to substantial savings over a month, especially when compared to the high costs of running a conventional cooling system.

I am thoroughly impressed with the efficiency and cost-effectiveness of this mini split air conditioner. In the summer, I expect it to outperform my central air conditioner by a wide margin. I plan on purchasing another unit to further enhance the cooling capability in my home.

(Note: This review has been rewritten in an objective and concise manner, focusing on the key points mentioned in the original review while maintaining a friendly and clear tone.)

I am extremely satisfied with this mini split unit. The installation process was a breeze, and I saved a significant amount of money by doing it myself. I only needed a technician to come out for vacuuming and testing the line set. It requires a 1-20 amp breaker and operates so quietly that I can barely hear it running. However, don't let its quiet operation fool you – it cools the room so quickly that it will freeze you out!

The customer service provided by the seller was exceptional. They were incredibly responsive and quick to address any concerns or issues I had. In fact, when the outdoor unit was not heating properly, the seller promptly sent me a replacement unit. I installed it myself and now it's working perfectly. I am grateful to the seller for their quick response and willingness to resolve the issue. I would definitely purchase from them again.

I have been using this mini split unit for about a month now and I am fully satisfied with its performance. It was professionally installed in just three hours, and it operates so quietly that I hardly notice it's running. Moreover, it cools the room quickly and efficiently. Although I have not yet received my electric bill to assess its energy efficiency, I am confident that it will meet my expectations.

The tech support provided was thorough and knowledgeable, and the issue was resolved much faster than I expected. Now, we can enjoy warm nights again! I highly recommend both this company and their machine.

The installation of this kit was incredibly easy, and it included everything I needed except for an AC pump to drain the lines. However, purchasing a refrigerator pump for around $100 to $150 was still much cheaper than buying a mini split kit with pre-refrigerated lines, which would have cost over $1,200. Both the indoor and outdoor units have an attractive design and provide extremely cold air, even in the scorching Arizona summers. It effectively cools a master bedroom to 70°F quickly. Contrary to what one may think, installing this unit is not complicated at all. There are numerous step-by-step instructional videos on YouTube that make the installation process a breeze. Additionally, if you're looking for Wi-Fi connectivity, there is a Wi-Fi USB stick available for these units. However, I would recommend purchasing a separate smart AC controller from Cielo or Sensibo for more advanced features within the app. Unlike Sensibo, Cielo smart AC controllers do not require monthly subscription plans to access all the features.

I also have central AC in my home, but I installed this mini split unit in my bedroom as the AC unit in the house is getting old and struggling to cool the entire home. I have not noticed any significant change in my monthly AC bill, which is a fantastic feature. Overall, I am extremely satisfied with this mini split unit and highly recommend it.

I have been in the HVAC industry since the 80s, and I must say that this residential HVAC unit is truly impressive. The compressor and fan on the condenser outside unit are incredibly quiet, which is quite remarkable. The variable speed feature also contributes to its impressive 19 SEER rating. Another great aspect is that the indoor evap unit continues to run throughout the night, ensuring consistent cooling. I even noticed that sometimes in the morning, the compressor is completely off, even when the indoor temperature is set at 72 degrees.

I decided to measure the voltage and current, and I was pleasantly surprised to find that this unit only pulls around 1750 watts at full load in 90-degree heat. This is a significant improvement compared to my previous 3.5-ton Goodman unit, which used to consume much more power. To cool our entire living space, I simply placed a box fan in the bedroom doorway, and it does the job perfectly. I couldn't be happier with the performance.

One important thing to note is that regular cleaning of the outside unit coil is crucial for maintaining optimal performance and cost savings. In my area, we have cottonwoods that tend to clog up the coil within a week. However, I found that using a garden hose to clean it works just fine.

Initially, I was hesitant about purchasing a "no-name" brand, as I didn't want to waste my money. But after receiving and using these units for a month, I am 100% satisfied with my purchase. The heating and cooling capabilities are incredible. However, I highly recommend hiring a professional for the installation. Cutting corners and attempting a DIY installation can potentially damage your expensive new air unit. Professionals have the necessary tools and gauges to ensure a perfect and long-lasting installation. Although the video may pick up some sound, in person, the unit is extremely quiet, almost unnoticeable.

I had a minor issue with the first unit where I only received the indoor unit. However, the customer service quickly resolved the issue and sent me a new set in no time. Once I had both the indoor and outdoor units, I was amazed at how easy the installation process was. I did have HVAC technicians come out the next morning to connect the two units, vacuum the system, and charge it. It's worth noting that the DIY installation isn't entirely DIY unless you have a vacuum machine. In such cases, it's essential to call a professional.

This unit performs exceptionally well, heating and cooling my shipping container tiny home with ease. It seems to be much more efficient than my tiny space heater, as there is no noticeable electrical draw when it powers up or off. I'm extremely satisfied and plan to use these units in all my shipping containers from now on.

I recently made the decision to switch from a central HVAC system to a mini split air conditioner due to ongoing issues with my previous system. After extensive research, I opted for the Senville Leto 36000 BTU mini split air conditioner and I couldn't be happier with my choice.

One of the main reasons I chose a mini split air conditioner is because it is ductless, eliminating the need for problematic ductwork. My previous central HVAC system had numerous leaks in the refrigerant lines, resulting in inefficient cooling and heating. Additionally, the cost of replacing the ductwork was quite steep. By choosing a mini split air conditioner, I was able to avoid these issues altogether.

The Senville Leto mini split air conditioner has received rave reviews and offers competitive pricing, which made it an attractive option for me. I purchased it directly from Senville through Amazon.com and it arrived at my doorstep within two weeks.

To ensure the warranty remained valid, I decided to have a licensed HVAC technician install the unit. Finding a technician proved to be a bit challenging, as many only install mini split air conditioners purchased directly from them at inflated prices. However, I found two technicians through Yelp.com who were willing to install the Senville Leto at a reasonable price.

The installation process itself was straightforward, but I would recommend reading the manual beforehand to familiarize yourself with the unit's operation and installation requirements. It's important to ensure that the lines are vacuumed and pressure tested for leaks, and that all connections are properly made according to the manual.

Having used the Senville Leto 36000 BTU mini split air conditioner for cooling and heating my home for the past two months, I can confidently say that it performs flawlessly. It cools and heats my house efficiently, providing the comfort I desire. I am extremely satisfied with my purchase and would highly recommend this mini split air conditioner to anyone in need of a reliable and efficient cooling and heating solution.

I recently installed the Senville ductless mini-split system in my master bedroom as part of a bathroom remodel. I must say, I am extremely satisfied with its performance.

Firstly, the unit operates quietly, especially when the fan is set on slow. This is particularly important for maintaining a comfortable sleeping environment in the master bedroom. The temperature control is accurate, ensuring that the room remains at the perfect temperature throughout the night.

During the installation process, I made sure to follow the recommended guidelines. I purchased the recommended adapter for connecting a standard gauge set, which proved to be necessary. To ensure optimal performance, I spent time pumping down the lineset and evaporator, conducting a pressure test with compressed air, and evacuating the system before charging it with 410a refrigerant. Additionally, I used a small bottle of nylog to prevent slow leaks on the flare fittings of the lineset.

While it may be possible for inexperienced DIY installers to skip certain steps, such as using a vacuum pump, I strongly advise against it. It is not only illegal but also leaves the unit vulnerable to issues caused by moisture in the lines and evaporator. Following the proper installation procedures is crucial for optimal performance and longevity of the system.

In terms of mounting the condenser, I used brackets purchased from Amazon and also ordered vibration isolation feet. However, I found that the unit itself was already so quiet and smooth that I didn't actually need the vibration isolation feet. Both the Senville unit and the aftermarket brackets came with rubber pads, but I didn't find them to be useful in this particular installation. I did have to use washers to secure the condenser to the brackets, as the bolt holes were large and the mating surfaces were not completely flat. This resulted in a less aesthetically pleasing fit, but it was functional.

I have included photos of the current status of the installation. In the future, I plan to add more insulation to the lineset and properly tape and seal it. I also coiled some excess length of the lineset outside by the unit to allow for flexibility in case I need to adjust its position. I made sure to avoid placing it too close to the outlet or inlet of my nearby larger condensers to prevent preheated air from being breathed in or fed to the other units.

Lastly, I routed the condensate line in PVC inside the wall and left the connection accessible behind the evaporator in a bathroom closet. This will make it easier to clear or flush the condensate line with bleach if needed.

I highly recommend these stainless steel brackets for anyone looking to install a mini split heat pump. They are excellent for units up to 18k size and require no more than 6" from the walk. These brackets securely hold the outdoor unit and are built to last.

The installation process was smooth and hassle-free. The package came with everything we needed to install the mini split onto our wall. The brackets were easy to assemble and fit perfectly onto the wall.

One thing to note is that these brackets are sold separately, unlike some other options out there. This means you will need to measure carefully to ensure everything fits correctly. However, the reasonable price of these brackets makes up for this inconvenience.

The brackets come with nice anchors for brick walls. The package includes 4 anchors, but I decided to add two more since my unit was large. This ensured extra stability and peace of mind.

In terms of durability, these brackets seem sturdy and have a good-looking design. They have been holding up perfectly so far, even in harsh weather conditions. However, it is worth mentioning that the bolts that come with the bracket may not be as high quality as some users might prefer. It might be worth considering purchasing higher-quality bolts separately for added security.

I recently purchased this split system unit and I must say, it is the quietest one I have ever encountered. Both the inside and outside units are incredibly quiet, especially considering that the outside compressor unit is typically louder. In fact, you wouldn't even know the unit is on unless you were right next to it. I installed it just outside my bedroom where the inside unit is located, and I cannot hear any noise from the outside unit inside my home. Despite having basic insulation and wood construction, there is no noise leakage from the outside unit.

The installation process is relatively straightforward and can be easily undertaken by anyone with a good DIY attitude. While I have experience with HVAC equipment and knowledge due to my profession, specialized tools are not necessary for this installation. The only recommendation is to use a vacuum pump before releasing the freon gas into the unit. Fitting the inside handler may be a bit tricky and requires two people, but the template and steel mounting plate provided make the process relatively easy. It may involve some awkward work above your head for about 10 minutes, but it is manageable.

When tightening the freon lineset connections, it is crucial to exercise caution. Although a torque wrench gauge is not required, tightening them securely with two sets of grips is sufficient. In my case, I took extra precautions for the outside concrete base unit due to the high water table and the risk of flooding during tropical storms or hurricanes. I used paver slabs, drilled holes, inserted bolts, and cemented everything together. This ensured the stability and durability of the unit.

It is worth noting that most of these units are manufactured by a central Chinese manufacturer and then rebadged. However, the entire package is well put together. I had a delayed delivery, but when I contacted the supplier, I received excellent customer service. The representative I spoke to was polite, knowledgeable, and provided me with helpful information. This level of customer service was greatly appreciated.
