We provide the detail you don’t find elsewhere, and that’s why homeowners come here to plan their project.

What is a Mini-split AC or Heat Pump?

Here’s an overview for those just starting to research these efficient systems that continue to grow in popularity.

  • Mini: This term refers to the fact that the outside unit of a mini-split system, technically called a condensing unit or condenser, is smaller than a standard split system outside unit. Maximum capacity of a mini split system is less than the capacity of a standard split system. It’s more compact, and it can be installed on the ground, an outside wall or the roof.
  • Split: This term means the system has an outside unit, the condensing unit, and an indoor unit called the evaporator or air handler. This differs from a package unit where the heat source and air handler are combined in one large cabinet. Each mini-split condenser works with up to eight air handlers in separate rooms or zones. Evaporators are installed in the ceiling (small), high on a wall (small and medium) or on the floor (large) based on project requirements.
  • Ductless: Mini-split systems are also called ductless systems because no ductwork is required. Refrigerant carries heat from the condenser to the evaporator when heating (heat pumps only) and from the evaporator to the condenser when cooling (AC-only and heat pump models) through separate lines installed through the wall (preferred) or roof (some commercial installations). An electrical power line runs between the two. A drain line from the evaporator runs to the outside to drain condensation when the unit is air conditioning and dehumidifying the space.

Some mini-split systems are AC-only models for warm climates; others are heat pumps that heat and air condition in cool climates.

Mini-Split vs. Traditional HVAC

ductless-vs-heat-pump1

AspectDuctless or Mini-SplitTraditional HVAC
NoiseVery quiet. Compressor unit placed outdoors. Internal units contain quiet fans.Window and through-wall air conditioners are much noisier. For traditional central air, noise depends on the placement of the compressor, often located in the garage or in a dedicated closet. Similar noise levels.
Zone Heating and CoolingDifferent indoor units can be adjusted or turned off based on demand. Multiple zones possible for each compressor unit, allowing fine control in various parts of a home.Central air units are usually multi-zoned by virtue of separate compressors, often zoned by floor or half-house. Less room-by-room control.
DuctsNo ducts, so changing large intake filters and cleaning ducts are not an issue. There may be smaller filters to change on individual units. No ductwork also allows the entire system fit into smaller spaces.Ductwork consumes significant internal space. Not an issue for homes designed around ductwork, but possibly a considerable disadvantage when retrofitting older buildings.
AestheticsEach head or cassette is visible in any room where mounted. While they can be placed with discretion, they cannot be completely hidden. Refrigerant lines must run to each zone inside or outside the building, but often are unsightly unless hidden inside walls.Ductwork and vents are usually located behind drywall, keeping them out of sight, with only a non-descript great opening where the air emerges. People don’t notice ductwork.

5 Factors Affecting the Cost of a Mini-split System

These four factors will determine your mini-split HVAC system cost.

1. Quality: As with all HVAC systems, ductless systems are available in a range of quality ratings. While not complete, this overview of top-selling brands helps sort them out:

  • Standard brands – moderate cost, 15 to 18-year durability: Pioneer, Gree, Classic America, Kingsfin, MrCool, Air Con, Kilmaire and Blueridge
  • Premium brands – higher cost, 17 to 25-year durability: Mitsubishi, Fujitsu, Daikin, Friedrich, Toshiba-Carrier, Bryant, Trane, American Standard, Lennox, LG, Panasonic

2. Performance: There are two issues to break down here:

  • Functions: AC-only units cost less than heat pumps that both heat and cool. Air conditioners usually have a +/-5kW electric heater to supply resistance heat, but that type of heat is inefficient and expensive compared to heat pump heating. Ductless heat pumps have small heaters too, but they’re only used for emergency heating if the heat pump fails.
  • Comfort: Compressors in some premium models have inverter compressors that are not only more efficient, they deliver quieter, more consistent heating and cooling without temperature fluctuations. They’re better at eliminating hot/cold spots, but they cost more than units with standard compressors.

3. Efficiency: Mini split system ACs and heat pumps range in efficiency from about 15 SEER to 38 SEER. This is a rating of the air conditioning efficiency, the Seasonal Energy Efficiency Rating, that describes how much cooling can be accomplished per the energy used. It’s like gas mileage, and higher ratings are more efficient. The rating for heating is HSPF, or Heating Seasonal Performance Factor, and ductless heat pumps start at about 9.0 HSPF and range to about 15 HSPF heating efficiency. Efficient units cost more.

4. Size: One criticism of ductless systems is that they are not as large as standard split systems, but then, they are typically used to heat/cool smaller areas. Single-zone mini split systems range in size from about 9,000 BTU to 42,000 BTU. Multi-zone systems create the same number of BTUs, but they are split between two or more evaporators. For example, a 36,000 BTU condenser might serve four 9,000 BTU evaporators. The larger the system is, the more it will cost.

5. Single Zone or Multi-zone: Because multi-zone systems typically have two to five evaporators/air handlers, their equipment costs are higher.

How to Size?

It’s 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 won’t 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 you’ll need, we’ve 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 you’ll need. It’s 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 (hot): 22-30 Btu/sq. ft.
  • Zone 3 (warm): 20-24 Btu/sq. ft.
  • Zone 4 (moderate): 18-22 Btu/sq. ft.
  • Zone 5 (cool): 16-20 Btu/sq. ft.
  • Zone 6 (cold): 14-18 Btu/sq. ft.
  • Zone 7 (very cold): 12-16 Btu/sq. ft.

Air Conditioning: Now, let’s 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. Here’s the size of the system you would need in each climate zone to cool the space:

  • Zones 1 & 2 (hot): 1,000 x 24-30 = a 22,000 to 30,000 Btu mini-split AC or heat pump
  • Zone 3 (warm): 1,000 x 20-24 = a 20,000 to 24,000 Btu mini-split AC or heat pump
  • Zone 4 (moderate): 1,000 x 18-22 = a 18,000 to 22,000 Btu mini-split AC or heat pump
  • Zone 5 (cool): 1,000 x 16-20 = 16,000 to 20,000 Btu mini-split AC or heat pump
  • Zone 6 (cold): 1,000 x 14-18 = 14,000 to 18,000 Btu mini-split AC or heat pump
  • Zone 7 (very cold): 1,000 x 12-16 = a 12,000 to 16,000 mini-split AC or heat pump

Heating: The chart must be flipped for heating because the cooler your climate is, the larger the heat pump needs to be. It looks like this:

  • Zones 7 (very cold): 1,000 x 24-30 = a 22,000 to 30,000 Btu mini-split heat pump
  • Zone 6 (cold): 1,000 x 20-24 = a 20,000 to 24,000 Btu mini-split heat pump
  • Zone 5 (cool): 1,000 x 18-22 = a 18,000 to 22,000 Btu mini-split heat pump
  • Zone 4 (moderate): 1,000 x 16-20 = 16,000 to 20,000 Btu mini- heat pump
  • Zone 3 (warm): 1,000 x 14-18 = 14,000 to 18,000 Btu mini-split heat pump
  • Zone 1 & 2 (hot): 1,000 x 12-16 = a 12,000 to 16,000 mini-split heat pump

How to Choose Right Efficiency?

There are several general rules to guide your choice, and most are just common sense:

  • Space in a cool climate requires a smaller air conditioner than the same space would need in a hot climate
  • Space in a cooler climate requires a larger heat pump than the same space would need in a hot climate
  • A replacement mini-split/ductless system needs less capacity if the space’s insulation has been upgraded or other energy-efficiency modifications have been made
  • The longer you intend to live in your current home or use your current commercial space (and pay monthly energy bills), the more sense it makes to choose a high-efficiency system
  • If you plan to sell soon, then it might not make sense to pay extra for greater efficiency, though listing a very efficient HVAC system on your sales sheet will attract energy-conscious buyers

How efficient should your ductless mini split system be? There are a couple ways to approach it.

By climate: For air conditioning, the hotter/longer/more humid your climate is, the more cost-effective it is to pay more for an efficient system. The same is true for heating in cold climates. The extra cost of it will be paid back in lower utility bills long before the system is retired, and you’ll be saving money every month past that point. Here’s what that looks like using the efficiency of the units available:

  • Zones 1 & 2 (hot): 24 SEER and more efficient air conditioning
  • Zone 3 (very warm): Minimum 21 SEER air conditioning
  • Zone 4 (warm): Minimum 18 SEER air conditioning
  • Zone 5 (moderate): Minimum 9.0 HSPF heating
  • Zone 6 (cool): Minimum 11.0 HSPF heating
  • Zone 7 (cold): Minimum 12.0 HSPF heating

By priorities: Many of our readers put eco-friendly sustainability at the top of their criteria list when choosing how to air condition and heat their space. If that reflects your values, then buying the most efficient mini-split system you can afford will give you peace of mind.

$3,200PioneerFort Worth, Texas2550 sqft
Last summer, our mini-split AC unit proved useless against the sweltering heat, which is why we decided to upgrade to the more powerful Pioneer 12000 BTU 230V mini-split system a few months ago. The unit is notably more industrious than the one we had although this comes at a cost: the whirring of the fan is a bit louder. Also, I noted a few accuracy issues with the inverter. The system keeps lowering the temperature of the room beyond the preset value (I had set it at 75 before I left for work. A few hours later my wife called complaining that the thermostat read 73). I intend to make calls to rectify this since I read that it is a common issue that stems from a faulty motherboard. Despite this minor hiccup, however, the unit runs well with noise levels that are bearable and smooth functionality. Once my problem is fixed, I would definitely recommend this to my friends.
$5,500Friedrich MC12Y3JMBoston, Massachusetts2800 sqft
I simply can’t say enough good things about the Friedrich MC12Y3JM Ductless mini-split AC. The lower price tag came with a lower BTU (12,000) but that was a sacrifice worth making in my opinion since it’s more than enough for my small condominium. The highlights of this unit are that it offers 4-way cooling and air flows that feel very natural (you won’t feel like you’re being blasted by air from an open window). Installation was swift, highly efficient, and very professional going by how excellently my unit is still running 6 months after installation. This is a purchase I am not likely to regret in the near future and I would totally recommend this unit for other small-apartment dwellers.
$6,950SenvilleLong Island, New York2340 sqft
I bought the Senville SENL-12CD mini-split AC about a year ago and it is still running well as new save for a few parts that have needed replacement over the past few months. One thing I and other buyers of this unit love are how quiet it is. We decided to go with professional installation mainly because the instructions provided in the manual are very unhelpful. Everything is vaguely described and surprisingly, the customer support will only get you more confused. Once properly installed, however, there is little we can complain about. Great unit overall!
$7,950MRCOOLGreen Bay, Wisconsin3,000 sqft
Immediately we found out that the MRCOOL 24,000 BTU ductless mini-split heat pump came with Wi-Fi connectivity that allowed us to easily control it via our smartphones, we were sold! The unit is touted as one of the easiest to install in the market but we’re the farthest thing from DIYers. Our busy schedules only allowed us a few hours to supervise the installation of the unit by professionals one afternoon, which was fairly straightforward. Since the installation was completed 3 months ago, we haven’t had any hiccups with what we think is an excellent ductless heat pump system that is well-worth the buy.
$6,550MRCOOLAspen, Colorado3,400 sqft
Initially, we had wanted to go for the 24,000 BTU MRCOOL but my brother (who is admittedly more tech-savvy) talked me down to the 18,000 BTU unit, which he thinks is more than enough for my quaint little bungalow. Installation was an absolute breeze (I would have done it myself but I was offered free installation by the store I bought it from) and done fairly well, save for a few missing screws which I replaced as soon as the technician left. The ductless heat pump does exactly what it says it will, something I can attribute to the refrigerant it uses. I also enjoy how easy it is to set the temperature on the go via an app on my phone. The future really is here, guys, and this is the ductless mini-split heat pump you should be looking at.
$7,800DaikinEssex, Vermont2,200 sqft
I needed a powerful mini-split heat pump for my home in Essex and the 24,000 BTU Conair unit came highly recommended. The noise levels are bearable when the unit runs on medium to high speeds but once the speed is lowered, it is ghostly-quiet. The air system keeps my house warm enough on frigid nights and is delightfully easy to adjust during hot afternoons. The installation job was also very professional and the unit looks like it will last a few more years without any tinkering or repair jobs necessary.

Finding a Ductless Heat Pump Contractor

Finding a good contractor to install a ductless heat pump is a bit more difficult than finding someone to install or service a forced air HVAC system, but it’s well worth it. Proper installation can mean the difference between cost savings and energy waste. This is especially for the refrigerant lines, where proper insulation is critical.

Probably the best way to find a certified contractor is searching from the website of the manufacturer of your preferred ductless heat pump. Fujitsu and Mitsubishi are the major manufacturers, and both companies have contractor search engines available.  Some states and utilities also have a list of contractors certified to these systems, so check with your utility company.

As with any home improvement project, due diligence is always good practice before hiring a ductless heat pump installation contractor.
