Mini Split Air Conditioners Number of Rooms (Zones) Price Low To High Price High To LowIf you're considering a ductless split system installation, you probably have some questions. Using highly advanced technology, Mitsubishi Electric Cooling and Heating makes some of the best ductless air conditioning systems on the market. These innovative cooling devices are highly efficient by delivering a consistent, quiet flow of cool air to keep you comfortable and conserve energy. However, split systems must always be properly sized to accommodate the indoor spaces they are designed to cool. The primary advantage of Mitsubishi Electric ductless air conditioning systems is that you don't need the duct work required by a central air conditioner. Another benefit is that, unlike central air conditioning systems, ductless systems are much easier to install. Split systems consist of an outdoor unit and one or more indoor units (air handlers).

The compressor and condenser coil are located in the outdoor unit, while the evaporator coil is situated in the indoor unit. A small hole of less than 3 inches in diameter is made in the wall to accommodate electrical wiring and copper tubing that connects the outdoor unit to the indoor unit. The outdoor unit transfers refrigerant from the compressor and condenser coil via the tubing to the evaporator coil in the indoor unit. Cooled air is then blown indoors by a fan that's virtually silent. The sleek and inconspicuous indoor units can be mounted on the wall or ceiling. You can regulate the temperature of each indoor unit with a remote control or a wall-mounted thermostat. Multiple indoor units can be connected to the same outdoor unit. Each indoor unit can then be programmed to maintain a different temperature, thus creating separate cooling zones. This differs from central systems where the thermostat setting determines the temperature in every room. Proper ductless air conditioner sizing is essential for high efficiency performance and the level of cooling capacity.

If the sizing is too small or too large, the system won't cool properly, and it won't operate efficiently. wall air conditioning units 12000 btuAnd if the system is improperly sized, if the indoor units are mounted in the wrong locations, or the installation itself is done incorrectly, you'll be left with an expensive problem to fix. tentang air handling unitSystems that are incorrectly sized and improperly positioned can seriously interfere with humidity control and cost a bundle in high electric bills.frigidaire ac heater wall unit Sizing a split system will depend on existing insulation levels, the area you want to cool and on how many indoor air handlers you plan to include. The more indoor units you want, the more precise the sizing must be.

Because you're investing in a high performance system, technicians at Mitsubishi Electric Cooling and Heating recommend professional sizing and installation. That way, you'll know the job will be done properly and that your investment will be protected. Ductless splits cool a larger area at the same BTU level than do window air conditioners and portable air conditioners. Below is an approximate sizing guide: 350 square feet = 9,000 BTU 500 square feet = 12,000 BTU 750 square feet = 18,000 BTU 1000 square feet = 24,000 BTU 1250 square feet = 30,000 BTU 1500 square feet = 36,000 BTU The expert contractors at Mitsubishi Electric Cooling and Heating do not recommend installing a mini split system yourself. Although these systems are easier to install than central air conditioners, it's best to hire a licensed and insured contractor who employs NATE-Certified technicians. There are safety risks involved, and the installation process requires high-tech tools and specialized techniques.

The installation must be performed in accordance with HVAC guidelines or it won't be covered under warranty. And although split systems come pre-charged, your technician may need to add more refrigerant to establish the correct charge. Mitsubishi Electric ductless systems have Seasonal Energy Efficiency Ratios (SEERs) of at least 13, while some inverter units boast SEERs of from 20 to 22. The higher the SEER rating, the more efficient the system will be. For maximum efficiency, Mitsubishi Electric Heating and Cooling recommends installing an air handler in every room. However, one indoor unit can certainly cool multiple rooms if the BTU capacity of that unit is sufficient to cool the area of the corresponding space.

Certified: AHRI, EnergyStar, UL 1995, CSA 22.2, ETL, & California Energy Commission SAVE >90% ON COOLING / HEATING COSTS Click here to download the solar AC specification sheet. This is the 4th generation solar air conditioner we've all been waiting for - designed for low cost, easy installation and a fast payback. This unique solar air conditioning technology requires no batteries, no inverter, no controller - just plug in the solar panels and start saving up to more than 90% on daytime cooling or heating costs. For home or office use, this system will cool an area for pennies with 90% or more of the energy coming from sunlight. In addition to cooling, the ACDC12b solar heat pump will provide solar powered heating, operating all the way down to an outside ambient temperature of 5F. No matter how far north or south you are, this is the right system for you. ACDC12b solar air conditioners need no batteries, and

only need two or three PV panels to deliver a huge savings. During the day, when air conditioning is needed the most, you can operate this unit with very little draw on yourAt night, you continue to save due to the >SEER 21 rating on this unit. The mini-split air conditioner design allows you to put solar cooling into the area where it's needed the most and avoid the security issues of an unsightly and noisy window unit. If your location needs heat during the winter, take a full 1-ton of the daytime heating load off of your main heating system and get a head start on evening heating requirements.  because it's a ductless system, it allows 100% of your heating or cooling to be delivered to where it's needed without the loss that occurs in a ducted system. Note - this is not 220v utility power is required. If you have no AC power and need an off-grid solar Solar Air Conditioning Cooling & Heating Augmentation

Augmenting a space heating or cooling system with solar makesIn addition to heating or cooling a small area, it allows you to add capacity to an existing system, or reduce the load on an existing system, either or both of which can save you money and add comfort. Solar augmentation also allows offsetting of higher daytime electricity rates and reduces the amount of early evening catch-up required by the normalThe ACDC12b hybrid solar air conditioner allows you to add comfort without adding cost, and can sharply cut your daytime heating and cooling bills. The ACDC12b installs just like a normal minisplit air conditioner, then you connect the solar panels using industry-standardYou can use 1, 2 or 3 normal solar panels (but not 12v "battery charger" panels) of 230w-300w each for a total of up to 900w. You can order the panels, etc. from us or purchase them locally, note the panels should be minimum 30v PV panels (30-39v),

please review the specifications. The ACDC12b uses R410a, an ozone-friendly refrigerant, so it is legal for the customer to self-install however we recommend hiring a professionalIf self-installing you will need a vacuum pump to commission the unit. Anti-Corrosion For Long Life Designed to last a long time even in coastal and/or island areas where salty mist, saline fog, or salt spray may come in contact with critical air conditioner components, the ACDC12B uses SeaSpray Anit-Corrosion Technology to protect the electronic and mechanical components from corrosion. On pure AC power when no free solar energy is used, official AHRI SEER is >21. With AC power input being reduced by free energy from 2x 235w solar panels, effective SEER can be calculated as >35. With free energy from the recommended 3x 295w panels, SEER can be calculated as >65 under good sunlight conditions. Note, there is no official SEER rating for units that blend free energy mixed with paid energy, however these numbers are calculated using the formula that is used for official SEER calculations.

The Manufacturers List Price on the ACDC12b is $1695. Solar panels, etc., are not included. HVAC professionals who purchase in quantity should contact us for dealer and distributor pricing.
