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; How do you calculate the BTU of an air conditioner? BTU is an abbreviation for British Thermal Unit, which is the international measure of energy. An air conditioner's BTU must be matched to the size of the room for adequate cooling.

BTU tables estimate different energy requirements. What do the BTUs of a gas furnace do? Measure the spaceMeasure the length and the width of the area to be cooled. ac unit conversionMultiply the length by the width to calculate the square footage of the space.moving an ac unit cost Use a table to determine cooling capacityCompare the square footage to a table showing recommended BTU ranges. heat pump air conditioner unitsFind the square footage of your measurement. BTUs required for the space are listed across from the square footage measurements. Make adjustments if neededAdjustments are required if the unit will be used in a heavily shaded or a very sunny room. In the case of extra shade, reduce the capacity by 10 percent. For very sunny rooms, increase the capacity by 10 percent.

Occupancy can also affect the BTU rating, with BTUs needed for each person when more than two people will regularly occupy a room. Kitchens require an increased capacity of 4,000 BTUs. Consider the location of the unit, as units that are located in corners where airflow may be interrupted require more BTUs than units that are more centrally located.

What are the best outdoor wood boilers made out of? Where can you compare features of Dri-Eaz dehumidifiers?The Rooftop Unit Comparison Calculator (RTUCC) compares high-efficiency rooftop air conditioners to standard equipment in terms of life cycle cost. This web application provides an alternative to complicated building simulation models while offering more detail than simplified estimating tools that are commonlyWhile simplified tools are typically based on full-load efficiencies and full-load equivalent operating hours, the RTUCC accounts for local climate and partial-load as well as full-load The Comparison Calculator assists decision-making regarding the purchase or replacement of packaged rooftop air conditioning equipment by estimating a product´s lifetime energy cost savings at various

Other key features include the following: The results obtained with the Comparison Calculator will be useful to facility managers, financial officers, energy management professionals, air conditioning contractors, and other decision makers interested in maximizing both energy-efficiency and cost-effectiveness of cooling system investments. The calculator provides energy and cost estimates suitable for comparison purposes. The RTUCC was not designed to replace building load simulating software for heating and coolingDue to the dynamic nature of building heating and cooling, actual energy use will vary depending on the application. The Comparison Calculator is a screening tool that estimates a product's lifetime energy cost savings at various efficiency levels. It provides energy and cost estimates suitable for comparison purposesThe Comparison Calculator is not designed to replace building load simulating software for heating and cooling systems design.
