Both Fujitsu and Mitsubishi have Extreme Low Temperature “HIGH HEAT” models, that can operate in temps as low as -15F and -13F respectively (xltH and H2i product lines). Wall and floor mounted indoor units typically do not require any extra installation work, and do not increase material costs. If you are unsure what each field means, or how to use it, see the detailed explanation below. This basically describes MY HOME! The cold/hot “freon” or R410A refrigerant is pumped from an outdoor compressor to the ultra quiet and efficient indoor unit, eliminating a central air-handler in your basement, and having to then push that air along the ducts. Therefore, it might make sense to have multiple single-zone units installed, instead of one large multi zone system. See All Videos & Help. However, in the US / Canada, as well as many other countries, the clear market leaders are Mitsubishi, Fujitsu, Daikin, LG and to a lesser degree GREE. Split Air Conditioner is designed for individual areas in your home. Moisture Removal Allowance: It is typical for roughly 30% of your air conditioner's capacity to be used to reduce the humidity in your home. Dual Zone Mini-Split Systems. Boiler BTU Calculator - Boiler Sizing Calculator - Boiler Sizing - Boiler BTU Calculator. Enter the width of the wall. PEX. However the true advantage is in the fact that you eliminate the need for ducts, which can cause as much as 30% of energy loss – especially in unconditioned areas, such as attics and crawl spaces. Heating Only (Primary System Usage) Given all the different options available for heaters –– space, vented, gas, console, and more –– narrowing down the choices can be a great way to ensure that you are choosing the best option. If you have a large house, you can estimate 3-4 zone system cost, and then just double that number for a 6-8 zone system. Mini splits deliver cold (and hot) air directly to the room where it’s needed, by placing individual air handlers on the wall, floor or concealed in the ceilings. So to make it simple we have two options for efficiency setting: Average and High. Once you fill out all fields that correspond to your specifications, click “calculate”. 2 Tons. This number will be used to determine system size in BTUs/tons that is most appropriate for your needs. Outdoor Design Temp. See costs in your area Costs of AC only vs Heat Pump / AC system are nearly the same. In addition, using concealed duct/slim duct air handlers, you can have “single zone” service in several small rooms, by running short ducts from a “central” point to adjacent small rooms, such as bathroom + hallway + laundry room, etc. However, (and unfortunately) most pros either don’t want to spend 2 hours (per project) calculating system size OR do not know how to do a Manual J calculation (properly or at all). The average price to install a single zone ductless (heat pump AC) system is $2,900-4,000. You can get a very precise estimate for the cost of installing ductless air conditioning. So far I’m extremely happy with it: If you have an older home with uninsulated walls / attic, single pane or double pane windows, air leaks, cold air drafts, etc, select POOR INSULATION. Select the system type needed for your home. This flexibility allows you to cover even large homes, and only run cold or hot air where you need it (compared to central AC, which typically has only one zone – the whole house). 1 BTU is the equivalent of 1,055 joules or .293 watts. Perfect Aire ductless mini-split air conditioners and heat pumps are the cutting edge of what modern, flexible fabrication can produce. By comparison, a 12K BTU unit from the same series (Model MZ-FH12NAH), is rated at 26.5 SEER (20% higher than its 18K BTU counterpart) and will run at much lower 3,700 BTU minimum capacity, using almost 1/2 the electricity of it’s “slightly older brother”. Disclaimer: This sizing tool, although based on a version of the ACCA Manual J, is for informational use and is intended only as a guide to assist with finding the best product for your needs. Mitsubishi mini split systems offer best-in-class performance and efficiency. Step 8) Location / US region. Dual Zone Mini Split Systems consist of one outdoor Air Conditioner or Heat Pump, two indoor Air Handlers and an installation kit for each air handler. An efficient mini-split heat pump can produce a lot of heat relatively cheaply, in temps as low as -15F or lower (Fujitsu single zone 9-15K BTU models of the RLS3HY series, which is what I have in my home). Many contractors and suppliers overestimate the tonnage in order to sell you a larger, more expensive system, as well as to cover their “rear”, in very rare cases of extreme hot or cold outside temperatures. ... Operating Cost Calculator; Learning Center. In addition, Daikin does not have HIGH HEAT units, and will only run in low temps up-to -4F. There is about $150-200 difference for a single zone, and up-to $750 difference for a multi-zone system. SINGLE-ROOM MINI-SPLIT SYSTEMS. It is just a ductless air conditioner, which means no heating, and much lower energy efficiency (on par with central AC systems, or even window-mounted AC)! We will use this to make an estimate of the quality of insulation of your home. PT1M42S. The amount of heat, rated in British Thermal Units (BTUs), that the unit can deliver into the space. Extra electric work is the most expensive part of using two single zone systems vs. one multi-zone unit. For example, prices in New England (MA, CT, RI, NH & VT) or on the West Coast (Pacific Region – WA, OR, CA) will be about 25-29% higher than those in the South Central regions (Texas, Louisiana / Alabama / Arkansas, Mississippi, etc). If you're constructing a multi-zone system, you may fill out the calculator for each room and add your load requirements together. If your doors are larger or smaller, please adjust accordingly. Thus, it falls outside the scope of a “typical” residential ductless mini split system. Operate as few as one indoor unit or all indoor units; Choose from ; indoor unit styles - wall mount, slim duct, compact cassette, and floor mount 8 Combinations are ENERGY STAR ® qualified You may also have your system custom-designed using the Sizing Worksheet and send it to eComfort where an expert will contact you with recommendations and help build your system.

Start Here - Enter Your Zip Code. While there are many multi-zone ductless systems, as you increase capacity (BTU rating/tonnage), overall system efficiency goes down significantly, for both heating and cooling! Others are all 2nd tier OR private labels (for example Lenox sells re-branded GREE systems under their own name). ft. space with rather poor to medium insulation level, in Boston, MA area (average winter temperature is 22F degrees), and costs $800-900 less in materials! If you choose to start over, all of your entered information will be lost. Fujitsu and Mitsubishi have the most efficient mini-splits in the world, with lower BTU models having as much as 33 SEER ratings. This calculation will not work for a whole house or commercial location, but is ideal for determining your mini split, through-the-wall, PTAC or window AC size. The key here might be the heater. Because there are many different options, sizes and brands, most homeowners are very confused about how much a ductless heat pump costs, as well as how to estimate proper system tonnage (BTU). Step 3) Heating + Cooling vs. Even at below freezing temperatures, there is still heat. Select 'Yes' if this wall separates the space being conditioned from the outdoors or an unconditioned space like a garage. Step 6) Choosing the right brand Heat pumps are only rivaled by high efficiency Gas-fired radiant/radiator systems, when it comes to heating energy efficiency / costs. Choose your HVAC installer wisely. Hello James, the usually 15,000+ BTU mini split units need run on 220V. Or perhaps your own bedroom, for those humid nights. Each single garage door should be counted as 1 and each double garage door should be counted as 2. Very few 2nd tier manufacturers will have a model that is specified to work up to -5F. While this covers their “behind”, it ends up costing a homeowner $1,000-3,000 more in upfront installation expenses, as well as $200-500 extra in energy costs each year, due to lower efficiency of larger systems, as well as higher minimum BTUs, at which these systems operate. (Cooling and Heating or Cooling Only) Select the optional heating type. Choose your region to get more locally-relevant prices, reflective of the cost of living, wages and material prices in your state. Most happy contractors/homeowners will typically not report that everything is GREAT. Select how many rooms or zones you want to have covered. Step 5) System efficiency To get the most accurate quote, carefully enter the value of each field in the calculator. We often refer to the British Thermal Unit as a BTU, but the rating is actually the BTUs per hour, or BTU/h. Enter the height of your ceiling. Heat Pump technology is what makes mini splits so energy efficient, as well as enables them to run in heating mode. If only a portion of the wall is "Exposed", enter this width. Users can also connect their solar energy to achieve the highest levels of energy efficiency and substantial savings.
