HVAC (Heating and Cooling Systems): Right-size Heating and Cooling EquipmentThere are 12,000 Btu’s per ton. The number 24 in the model number indicates the unit is 24,000 Btu’s, divided by 12,000 Btu’s per ton, equals 2 tons. 24,000 Btu’s/12,000 Btu’s per ton = 2 tons If you’re still unsure which system size is right for you, or if you’re having difficulty downloading the Air Conditioner Size Calculator , please e-mail us or call us toll free number at 1-855-634-5588. (Hint: Use the larger of the two numbers above if you’re unsure of your home’s insulation) Simply multiply the appropriate factor above by your home’s total heated square footage to arrive at your approximate required heating capacity. For example, if a furnace has a listed input rating of 100,000 Btu’s and an efficiency rating of 80%, it will produce For this example, using an 80% efficient furnace, the 2000 square foot home above would require a 100,000 Btu input furnace which will produce the necessary 80,000 Btu’s output of heat.

Variables such as your insulation, type and number of windows, number of stories, construction type, etc. will greatly affect the required Btu’s per square for both heating and cooling. The less insulated and more windows within the environment, the more likely you will experience greater air and heat loss.Picking the right home air conditioner is very easy with the right information. Before buying an air conditioner, find out how many BTUs you need.  This means think of the size of the room, and what the room will be used for. Matching Btu requirements to room size is very important when you buying an air conditioner system. This air conditioner sizing tutorial will explain you how to choose the right air conditioner size. Choosing an air conditioner size that is too small (low BTU rating) for the intended room will leave you feeling hot and flustered!

And buying an air conditioner that is too big for the room can have its problems too. So the main question is what does BTU mean? Btu – British Thermal Unit (Btu) is the international measure of energy. A Btu is the amount of heat needed to raise 1 (one) pound of water by 1(one) degree Fahrenheit. In HVAC industry, Btu's measure the quantity of heat a conditioning unit can remove from a room per hours. One BTU per hour is equal to 0293 watts. mobile air handling unitAs the Btu rating increases, so does the weight, size and cost of the air conditioner.window ac unit alternatives To calculate how many BTU’s you need you can use this table.window ac unit low profile The following tables are estimates based on average room conditions in a moderate climate.

Exceptions are Kitchens – add 4,000 BTU cooling capacity to the recommended size. High Ceilings/Unusual Floor Plans – increase BTU by 10%. Warmer Climates – may require 10-20% additional BTUs per room over regular amount. BTU size too large: A conditioner that has a bigger BTU rating than the room size needs will cycle off too quickly. The unit will not remove the humidity from the air properly. Air Conditioner size too small: A conditioner that has a smaller BTU rating than the room requires will run continuously. The unit will not cool the room adequately. NorthCool home air conditioner systems are normally 9,000 – 24,000 Btu's. This BTU rating provides sifficient cooling capacity for any home, condo or loft. If you have any questions please contact NorthCool's distributor near you Air conditioning (A/C) comes in various types and sizes of equipment that all offer the highest cooling potential, but also the highest cost to operate compared to other cooling approaches like ventilation or evaporative cooling. 

The cost to install average air conditioning depends upon type, cooling capacity and zone coverage, efficiency rating, preparation and special needs, and the labor rate.Type and cost summaryIn the following table the Cost figure is based on average air conditioning for zones ranging from 340 sq.ft. and includes transport, material, equipment, and waste.Type (cooling zone)ProsConsCostWindow (340 sq.ft.)Easy install/removeWindow blockage$253Low costWindow only locationLesser efficiencyPortable (340 sq.ft.)Easy install/removeDucted exhaust$345Low costOccupies floor spaceFlexible locationDuctless (600 sq.ft.)Flexible locationSome wall-cutting$1,416Higher efficiencyWall (1,000 sq.ft.)Flexible locationWall opening$2,225Under windowCentral (1,000 sq.ft.)Higher efficiencyDucting adds cost$3,598Multiple zonesSome wall-cuttingThermostatsOther considerations and costsTaxes and permit fees are not included.For A/C units of greater than 12,000 BTU/h (or 3.5 kilowatts) a multi-phase electrical circuit is generally required.

Add 600 BTU/h per person if usually occupied by more than two persons.For the kitchen, add 4,000 more BTU/h than required for room size.DIY considerationsWindow and portable units are highly suitable for DIY, and split systems are commonly provided with a DIY kit from vendors.Wall and central units require greater skills and perhaps professional licensing. Cost to install air conditioning in my city Cost to install air conditioning varies greatly by region. Following air conditioning sizing recommendations saves homeowners money. Without proper guidance from a home heating and cooling professional, many people will spend extra money buying air conditioners that are too large for the space. By buying the proper size of air conditioner, homeowners save money in the short-term, with a smaller cash outlay for a unit that is not too large for the space. Long-term operating costs go down with smaller, more efficient units as well. Air conditioning sizing does not follow the “bigger is better” adage.

In fact, an air conditioner that is too large for a room won’t cool the area uniformly. Additionally, a smaller unit that stays on continuously to create a consistent temperature in the room operates more efficiently than a large unit that turns on and off frequently. A unit that continues operating for longer periods of time at a lower level also dehumidifies the area more efficiently. Removing humidity from the air makes a room feel even cooler. Experts provide guidelines and recommendations for the size of air conditioning unit that is appropriate for any home. If you’re unsure about the size of air conditioner that your space requires, ask a professional contractor or salesman before you buy. The heating and cooling industry rates air conditioners’ cooling capacities based on British thermal units (BTU) per hour, or by the “ton,” which is 12,000 BTU per hour. Most room air conditioners have cooling capacities ranging from 5,500 BTU to 14,000 BTU. Depending on how hot your local climate gets in the summertime, a 5,000 BTU air conditioner will cool a room of 100 to 150 square feet.
