What To Know About Ductless Ac
- Cost: A single-zone system with one indoor unit starts around $3,000, including installation. A four-zone system costs about $12,000, installed.
- Installation: You’ll need a pro to mount the indoor and outdoor units and connect the 2½-inch-wide bundle of refrigerant lines and electric cables.
- Maintenance: The filter on each indoor unit should be removed and cleaned every month. Once a year, have a technician check refrigerant pressure and flush condensate lines.
- Noise: Indoor units have whisper-quiet squirrel-cage fans driven by long-life DC motors. Decibel ratings run at about 25, roughly the same as rustling leaves.
- Warranties: Coverage ranges from 5 to 12 years, but you can expect this sort of mechanical equipment to last 15 to 20 years before it needs to be replaced.
- Rebates: A few utilities offer rebates for installing ductless AC systems. Many more incentives are available for heat-pump systems. To see whether you might be eligible, go to energystar.gov/rebate-finder.
Beware of installers who size a split AC unit using a rule-of-thumb estimate. More often than not, the result is oversize equipment that’s costly to operate and can’t effectively reduce humidity levels. Instead, insist on a Manual J heat-load calculation. It figures system size based on math and factors such as climate, insulation levels, and sun exposure.
Make Your Cooling And Heating Smart
Ductless cooling and heating can very easily be made smart with plug and play smart AC controllers, like the Cielo Breez Plus or Cielo Breez Eco. Smart AC controllers provide you with air conditioning controls from the convenience of your smartphones, making your air conditioner WIFI compatible.

More Words About New Ducted Mini
Mini split is a term that has been synonymous with ductless for decades, but now mini splits are produced for ducted use too. Most of the brands are making ducted systems. This includes LG, Mitsubishi Electric, Daikin, Pioneer, Panasonic, Gree and Fujitsu.
Ducted mini split systems are preferred by home and business owners that dont want a conspicuous wall, ceiling or floor unit competing with their décor.
These systems can be installed as retrofits in homes and businesses, making use of the ductwork.
Ducted Mini Split Options
As with ductless systems, ducted mini splits are available in single and multi-zone systems.
Single ducted mini-split system: A single indoor unit is served by one outdoor unit. There are two common installation options. First, the indoor unit can be installed in a wall between studs and covered with a grill made by the manufacturer for the purpose. The second option is to install the unit in the wall or floor ductwork near an air grate.
Multi-zone ducted mini-split system: These systems feature one large outdoor unit and two to eight indoor units. The indoor air handlers are installed in the wall or in existing ductwork near existing grates, so air is pushed a very short distance. Far less airflow is required with this type of installation than in a standard split system that forces air from one central location to multiple grates.

Ductless Split Ac System
- The split system has three main parts. The compressor which is located outside, the inside air outlet and a remote control.
- The compressor and the inside air outlet can be placed up to 50 feet apart and still function properly.
- Additional materials used for installation include copper tubing that connects the outside and inside unit. The tubing carries the necessary refrigerant to operate the system.
- A plumbing connection is also necessary to drain the condensation accumulated by the system. A line can be piped into an indirect drain in the home such as the one used for a washing machine or a dedicated drain may be used to redirect the condensate.
Where Should A Ductless Air Conditioner Be Installed
The recommended placement is at least seven feet above the ground, but as close to the ceiling as allowed. This will vary depending on each brand, so your best bet is to follow the recommendations of a ductless air conditioning expert in Kendall, FL. Bedrooms: Units in bedrooms should be placed above the bed.

Efficiency Vs System Cost
All cooling systems carry a Seasonal Energy Efficiency Ratio rating, which compares cooling capacity with the amount of electricity used over the course of a typical cooling season. Ratings on today’s systems range from 13 to 33 SEER. As the graph below shows, the higher the rating, the more you’ll pay for your system, and the lower your electricity bills will be come summer. To see what effect SEER ratings have on estimated operating costs in your area, go to the central AC life-cycle cost calculator at energystar.gov. System prices come from acwholesalers.com.
* Based on a 1-ton system in St. Louis at 12 cents per kWh
** Calculated from 1-ton pricing
What’s a Ton?
In the parlance of air-conditioning, a ton is not a measure of weight it’s a measure of cooling capacity. One ton of cooling extracts 12,000 Btus per hour from a space. That’s enough heat to melt 1 ton of ice within 24 hours, hence the connection between weight and comfort. The capacity of ductless systems ranges from 34 to 4 tons.
What Size Do I Need
Its important to properly size the unit to serve the space it is installed in. The disadvantage of the unit being too small is obvious you wont get enough heat or cool air. But a unit that is too large will have problems too such as producing temperature fluctuations and failing due to short-cycling.
Asking your HVAC technician to perform a Manual-J Load Calculation test is the best way to properly size your ductless system for the space it will serve. However, since we want to help you estimate the size of the system youll need, weve created this quick and quite-accurate table.
First, find your location on this map of climate zones in the United States.
Now, the warmer your climate is, the more BTUs of air conditioning youll need. Its the reverse for heating in cool climates. Mini-split systems are not a good choice as the only heat source in climates where temperatures are regularly below freezing.
- Zones 1 & 2 : 22-30 Btu/sq. ft.
- Zone 3 : 20-24 Btu/sq. ft.
- Zone 4 : 18-22 Btu/sq. ft.
- Zone 5 : 16-20 Btu/sq. ft.
- Zone 6 : 14-18 Btu/sq. ft.
- Zone 7 : 12-16 Btu/sq. ft.
Air Conditioning: Now, lets translate those numbers into space. Consider total space of 1,000 square feet which might be one very large space or several smaller zones, such as four 250 square foot rooms or zones, each served by an evaporator. Heres the size of the system you would need in each climate zone to cool the space:

How Wed Pick A Brand
We found four leading brands in our research: Mitsubishi Electric, Fujitsu, LG, Daikin, and Panasonic . You probably dont have a ton of choice on which exact pieces of equipment you needthats determined mostly by your homes size, climate, and the heating and cooling needs youre addressing. But you do have a choice to make on what brand you go with, and in a big market, you can take your pick among qualified installers recommended by each of those four manufacturers. We evaluated the options by looking broadly at the characteristics common to the brands as a wholecomparing things like warranty, aesthetic options, smart features, and other factors that would make a meaningful impact if we were shopping for ourselves. Heres an overview by brand, in the order in which we would begin our search locally.
Daikin is another worldwide company that offers a large selection of units. They have a wide ranging network of installers and, like Mitsubishi and LG, a 12-year warranty for many of their products. The company offers many rebates as well as multiple control options.
There are other manufacturers out there, but we cant really imagine bypassing these four options for a niche brand with weaker availability, selection, and customer support.
Three: Integration With Air Quality Products
The filtration options for ducted, central air systems are much more robust than they are for mini-splits.
Additionally, numerous air quality products integrate easily with whole-home, ducted systems. These include humidifiers, dehumidifiers, and air purifiers.
The net benefit to your air quality can be profound with one or more of these. Add-ons like the dehumidifier can also work with your ductwork to reduce the workload on air conditioning, which can contribute to overall efficiency.

The Best Ductless Mini Split Air Conditioner
Weve reviewed this guide, and we still stand by all of our advice.
A mini-split is an efficient, scalable way to add cooling or heating to specific rooms of a home. Also known as ductless mini-split air conditioners and heaters, they consist of one or more wall, floor, or ceiling-mounted indoor units connected to an outdoor compressor. Theyre easier to install than a full ducted system, more efficient than window units or central HVAC, and they often make sense as a supplement to your existing heating and cooling equipmentgiving a boost to an isolated area of your home. Add in thermostat-like controls alongside smart-home integration and mini-splits start to sound pretty greatbut they arent cheap, with installation costs that can reach into the five figures.
The exact mini-split equipment you need depends on your homes unique heating and cooling requirements, and your options are limited to the qualified installers in your areabut weve researched this topic enough to be able to tell you about the scenarios when mini-split systems make sense and how to decide among the brands available. We asked installers, manufacturers, and homeowners who have mini-split systems to tell us what anyone considering one would need to know.
Ductless Ac Labor Costs
Comfort and energy efficiency are the biggest advantages of mini-split systems. But if your ductless system is installed incorrectly or if it is not the right size, you will not experience either of those benefits.
Unless you are a builder or remodeler, it is worth hiring a ductless air conditioner installer with the right tools in their belt. The contractor has to lay concrete for the outdoor unit, cut a hole in the exterior wall, run the electrical lines for the conduit, and perform other tasks as needed, such as getting rid of some of your current systems components. You can expect to pay between $1300 and $2000 for these components.
While you may be tempted to settle for the best price regardless of specific experience, remember that ductless heating and cooling systems are still a niche market in the U.S. You may have to hunt a little for the right contractor, so dont settle for someone you are not sure will do a good job just because they offer the best price on labor and installation costs.

How Wed Pick An Installer
Who you hire to install a mini-split system is as critical and difficult a decision as choosing the equipment itself. The machinerys performance shouldnt vary much, and defective units will be covered by warrantybut the commitment you make to an installer will determine how well the mini-split system functions in your space. A good HVAC firm will know what equipment to useespecially for tricky jobs that require some expertise and experience to design aroundand the technical skill the pros bring to the installation will affect its initial performance as well as whatever service calls you make over the years. No pressure!
There are companies, like Mr. Cool, that offer models that are marketed for DIY installation. These units are less expensive, but the installation process is not for the beginner, or even intermediate DIYer. It involves electrical work, plumbing, checking for refrigerant leaks, and drilling a 3½ -inch hole through the side of your house . This is not something that most people want to undertake just to save a couple thousand dollars. And after all of that, the warranty is shorter than the one provided by companies like Mitsubishi and LG. These DIY models are certainly an option, but not one to be taken on without carefully considering what you might be getting yourself into.
To give yourself a good chance at a satisfying mini-split installation, heres how wed approach the contractor hiring process for this job:
Get Utility Rebates With Ductless Heating And Cooling

When To Select A Ductless Air Conditioner
If you only plan to boost your existing air conditioning to fight off humidity and heat, then you may not necessarily require a heat pump. Instead, you can purchase a ductless air conditioning system.
The system specifically supplies cold conditioned air into zones in your house due to its design. This is an excellent alternative if you do not require any heat at all. For instance, for those who live in an area that has an arid or a tropical climate, then a ductless air conditioner will perfectly suit their needs. The option is also excellent to cool individual rooms such as a server room or the sunroom.
Pro #: Better Efficiency And Air Quality
Mini-split systems are consistently more energy efficient than traditional HVAC systems because they don’t lose conditioned air to leaky ducts.
Over time, ducts can tear or separate at the joints. When this happens, some of the air you’re paying to cool or heat your home leaks out of the ducts into areas you don’t want it to. This causes your system to run more to keep up with the lost air.
Since ductless HVAC systems directly supply the room they’re cooling or heating, they don’t lose any efficiency to leaky ducts.
Also, some manufacturers offer a cleaning feature on ductless systems , which filters the air multiple times to help reduce moisture and provide cleaner air. With forced air systems, you have to install a separate air filtration system to improve air quality.

What About Smart Controllers
We tested three smart thermostat devices: the Ambi Climate 2, the Flair Puck, and the Sensibo Sky. At their most basic, they allow you to easily control your mini-split from your phone. Unlike manufacturer options such as Mitsubishis Kumo Cloud, which do the same thing, these 3rd party options do not require expensive professional installation. Though none of the three have so far lived up to our expectations, the Ambi and the Flair are much better than the Sensibo. Were continuing to watch new releases and version upgrades and will test any that we think look good.
The Ambi Climate 2 is the most in-depth of the three. It attempts to monitor your home, AC use, and external temperatures then adjust your AC throughout the day. We like the set-it-and-forget-it use of it and how it adapted to our routine, but the apps depth, amount of upfront information, and optional user settings makes it more complicated to use than others we tried. The controller units are not wall mounted but unobtrusive within most modern decor. Our experience with customer support was good but not great.
Both the Ambi and Flair had issues with connectivity, especially with dual band WiFi. The signal strength of the units to the AC is hit or miss. When it works we were able to set them up over 25-feet away without an issue, but the best range seems to be closer to 12-feet. Good enough for a small room, but tougher in larger ones.
