What Size Ac Do I Need For My House

Home ac systems are bachelor in 3 principal categories: traditional split-system air conditioners, packaged air conditioners and ductless systems. Each of these operate past the same basic procedure to lower the temperature and dehumidify the air in our homes. They all require an evaporator coil, a condenser curl, a compressor and refrigerant to essentially pull estrus and humidity out of the home while returning libation air to your living spaces. Regardless of which type of system works all-time for your home, correctly sizing it will provide the best results in comfort, performance and energy-efficiency. For about people, determining the proper size will be best handled by a professional HVAC contractor.

An HVAC contractor will understand the variables involved and be able to perform the cooling load calculations necessary for proper Ac system sizing. However, understanding some of the principles backside cooling organisation sizing and the reasons why it'due south and so important will be helpful when because a new system for your home. For example, when it comes to the size of your dwelling house air conditioner, bigger is non necessarily improve. Equipping your infinite with a larger system with also many tons of cooling capacity not only uses more energy than necessary, merely an oversized air conditioner could also bike on and off too quickly without adequately removing humidity from the air, leaving you feeling absurd only clammy. Conversely, an air conditioner that's also pocket-sized for your space will piece of work overtime trying to absurd the space, consuming more free energy without fully doing the job. A properly sized air conditioner matched to the unique needs of your home will not only keep yous comfortable, it tin also help you salvage on your energy bills. Considering there is no simple answer to the question, "What size air conditioner do I demand?" and because it is so important to your condolement and free energy consumption, we always recommend getting a professional assessment of your belongings. Your local Carrier HVAC dealer can business relationship for all of the factors involved and determine the optimal Ac unit of measurement size for your abode.

How Are Air Conditioners Rated?

Air conditioners are typically rated ii ways: cooling capacity and energy efficiency. When you ask the question, "what size AC unit of measurement do I need?" y'all'll be interested in cooling capacity equally measured in BTUh or tons. To compare energy efficiency between different Air-conditioning units, you'll commonly look for the SEER, or Seasonal Energy Efficiency Ratio, which is kind of similar the air conditioner version of miles per gallon for a car.

Cooling Capacity

Cooling chapters offers a concrete measure to assist determine whether a item air conditioner is an appropriate fit for your infinite. An air conditioner'southward cooling chapters is expressed in BTUh (British Thermal Units per 60 minutes) or tons (oftentimes referred to as "tonnage"). Both offer a measurement of an air conditioner's cooling ability over an 60 minutes's fourth dimension. One ton of cooling capacity is equal to 12,000 BTUh. Residential air conditioners usually range from one.5 to 5 tons (or, 18,000 – 60,000 BTUh). Anything with larger cooling capacity would exist considered light commercial. Tonnage ratings are typically expressed in increments of .5 tons, and then residential air conditioners are ordinarily rated as one.v, 2, 2.5, iii, iii.5, iv, 4.five or five ton units. It should be noted that at that place is a singled-out difference between BTU and BTUh. BTU, or British Thermal Units, is actually a measurement for the amount of heat needed to raise one pound of water by ane caste Fahrenheit. BTUh represents a measure of how much rut in BTUs an air conditioner tin remove from your home over an hr'due south time.

SEER Rating

Air conditioners utilise SEER ratings to indicate energy efficiency. SEER stands for Seasonal Energy Efficiency Ratio and is used to aid consumers make informed choices most the systems they choose for their homes. By definition, SEER ratings are the total amount of cooling provided during the unabridged cooling season divided by the total electrical input during the cooling season. Much similar MPG (miles per gallon) for a car, the higher the SEER rating, the more than free energy efficient the system. Bear in heed, 2 AC units with the same cooling capacity could have very different SEER ratings. For example, when looking at two unlike iii-ton air conditioner models, one might be rated at 13 SEER, and the other might exist a much more efficient 19 SEER unit. Higher efficiency units may receive special certification chosen ENERGY STAR®, a Department of Energy program that recognizes consumer products for their energy saving capabilities. If an Air conditioning unit has earned an Energy STAR^® certification, information technology has a higher SEER rating and uses at least eight% less free energy than conventional models. ^[i]

Estimate the Right-Size Air conditioning Unit of measurement for Your Square Footage

While there are formulas available to help you judge the correct sized Ac unit for your home, the easiest and about accurate method is to rely on a Carrier^® HVAC dealer.

Additional Variables

There are many variables that must be taken into consideration when determining the correct size Air conditioning for a home. Factors that your dealer will take into consideration include:

Total square footage of interior space to be cooled
Approximate amount of straight sun exposure
Head count of typical number of people at home
Types and numbers of appliances or equipment that generate heat
Weather conditions/climate
Quality and full number of exterior windows
Quality and R-value of insulation
Type of structure, such as brick exterior or vinyl siding
Interior ductwork/airflow assessment
Features that contribute to heating & cooling loss or gain, such as fireplaces or skylights
