Although you may reasonably use this estimate as a first pass when browsing through furnace or air conditioner models, you (or your HVAC contractor) should complete a thorough load calculation before you make your purchase. 1. Square footage of your home: square feet (ex: 2400) 2. Which of the following statements best describes your home and its insulation? No insulation in walls, ceilings, or floors; windows and doors fit loosely R-11 insulation in walls and ceilings; no insulation in floorsdoors and windows fit fairly tight R-19 insulation in walls, R-30 in ceilings, and R-11 in floors;

tight-fitting storm windows or double pane windows "Superinsulated" house with R-24 wall insulation, R-40 in ceilings, and R-19 in floor; or double pane windows; vapor barrier sealed carefully during Earth-sheltered house with little exposure; Geothermal heat pumps vary in size from home to home. There are a number of factors that determine how big of a pump. Since sizing a geothermal heat pump is a intricate process you'll need to contact a qualified geothermal heat pump installer. An installer will start with an analysis of the heating and cooling demands of your home. From there he'll be able to calculate the right size system. The size of the system will dictate the size of the loop field. It is very important to contact an experienced geothermal professional before choosing a heat pump size because there can be problems with undersized and over-sized systems. A quality contractor will design the system accurately which ensures a long lifespan and low operating costs.

A geothermal heat pump has the potential to save you as much as 70% on your heating and cooling bills but with an undersized system you may find yourself paying for it in both comforthow to replace an ac unitSystems are generally sized in tons, an average home might be 3 tons, while a larger home might be 6 tons. clean ac unit insideLarger systems are more expensive because of the increased size of the loop field and larger geothermal unit.air conditioning units for residential homes If an undersized system is installed it will strain to reach your desired heating and cooling needs. This could result in high utility bills as the heat pump tries to make up for its size by using more electricity. An undersized system will prevent a homeowner from reaping the greatest benefits of geothermal: reduced utility bills.

Never choose your contractor based on price alone. An inexperienced contractor can under-size your system, thus the installation cost will be less expensive but the results will be poor. A good contractor will do their homework and correctly size the system. You should never have an option of different size systems, there is only once correct answer! Ask your contractor how they came up with the system size, it should not have anything to do with what size system you had prior. Some people may believe that installing an over-sized system to err on the side of caution is a safe choice, but this is a misguided assumption as an over-sized system comes with problems of its own. over-sized system can produce too much airflow at a given time resulting in extremely short runShort run times cause the system to cycle on and off very frequently once again reducingA geothermal heat pump is expected to be 300%-400% efficient, but too large of a unit causes significant decreases in this efficiency.

And once again, decreased efficiency results in higher electric bills. An over-sized unit will also have a negative effect on the comfort level of the occupants. the hot and humid summers a short run time will cool a room but fail to remove the air’sWhile your home may be cooler it will still be clammy and sticky. of equipment operate for a fixed period of time and if the equipment is over-sized it can overshoot the thermostat setting causing a home to overheat in the winter and become an icebox in the While the geothermal heat pump equipment size is based on the heat gained and lost, the loop field depends on the size of equipment, soil type and climate conditions. To clarify, the loop field is the series of piping that is placed underground. As would be expected, the larger the geothermal system’s equipment, the larger the loop field must be. A larger loop field may mean the drill has to go deeper, the field has to be longer, or the pipes must be installed farther apart loops in order to move more heat to and from the ground.

Soil type affects the necessary loop field size because different types of soil have different abilities to absorb energy. Extremely dense soils, such as rock and clay, have the ability to hold a great deal of heat and can therefore transfer more heat. Sandy soils absorb far less heat and therefore require a larger loop field. As a general rule of thumb, the drier the ground the larger the loop field required. Sizing a geothermal heat pump is a complex process and therefore it is important to contact a qualified geothermal contractor before making any decisions.If 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. And 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. Systems that are incorrectly sized and improperly positioned can seriously interfere with humidity control and cost a bundle in high electric bills. 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.
