How Many BTU’s Do I Need?

A British Thermal Unit (BTU) is a metric utilized to calculate thermal energy. It represents the total amount of energy required to increase the temperature of 1 pound of water by a total of 1 degree Fahrenheit. With central air conditioning systems, the BTU rating is utilized to measure the total amount of energy used to eliminate the heat from the air of your home.

An average central air conditioning system will feature a BTU rating between 60,000 to 80,000 or higher. A central air conditioner with a high BTU rating is able to produce more cold air when compared to a system with a low BTU number. If you have a large house, you will want to choose a central air conditioning system with a high BTU rating. On the other hand, a smaller house will require a system with a lower BTU rating because it doesn’t require a large quantity of cold air.

How to Calculate the Total Amount of BTU’s You Require

The size of all central air conditioners are indicated in tons. This metric is utilized to measure the total amount of heat an air conditioning system is able to remove in an hour. For example, an air conditioner that is 1 ton is able to remove a total of 12,000 BTU of heat per hour. To calculate the total number of BTU’s you need for your home, measure the length and width of each room in your home to calculate the total square footage.

Once you know the square footage of your house, multiply it by 25 BTU to obtain the total number of BTU’s required to maintain a pleasant temperature in your home.

Calculating the Total BTU’s Required Per Room

For example, if you have a room that is a total of 450 square feet, you will be required to purchase a central air conditioner with a minimum of 11,250 BTU’s. To calculate the total square footage of your home, measure the length and width of each room in your house to obtain the total square footage.

Calculating the Total BTU’s Required For Your Entire House

If you have a home that includes a total of 2,400 square feet, you should purchase a central air conditioning system with a minimum of 60,ooo BTUs of cooling capacity. This was calculated by multiplying 2,400 square feet by 25 BTU. We multiplied the total square footage by this value because an average home will require a system that can remove 25 BTU of heat per square foot.

5 Benefits of New Energy-Efficient Air Conditioners

Variable Speed Motors

When our team performs a central air conditioning installation appointment, we will give you an option to add a variable speed motor to your HVAC system. This type of motor is able to provide superior airflow in homes. In addition, variable speed motors are able to eliminate cold spots throughout the house.

Produce Little to No Noise

Since the latest energy-efficient air conditioners produce a low amount of noise, they will not be disruptive when you are sitting or entertaining guests in your backyard. While our team is preparing to perform the central ac installation, we will help you select an air conditioner that is the proper size for your house.

Environmentally Friendly

If you have an air conditioner that was produced prior to 2010, it may be utilizing refrigerant that is harmful to the Earth’s ozone layer. While our HVAC contractors near you in Arlington and Centreville are performing your central air conditioning installation project, we will help you select a system that is using the environmentally friendly R-410A refrigerant.

High SEER Ratings

When our team is preparing to perform a central A/C installation on your property, we will help you choose a system with a high Seasonal Energy Efficiency Ratio (SEER). A SEER rating is a ratio of the cold air output provided by a central A/C throughout the summer months divided by the total energy it consumes in Watt-Hours. 

While the minimum SEER rating of new air conditioners on the market is 13, our HVAC contractors near you in Virginia recommend purchasing a system with a score of 21 or below. Give us a call by phone at (703) 543-9649 or book an appointment online to receive help. Snell Heating & Air Conditioning provides fast and reliable air conditioning services in areas of Virginia such as Reston, Arlington, Centreville, and Alexandria.

Superior Moisture Removal

While we are preparing to perform a central A/C installation on your property, we will discuss the importance of choosing a system with a proper Sensible Heat Ratio rating (SHR). The SHR rating is a metric that is utilized in the industry to measure the ability of an A/C system to remove excess humidity from a home. For example, a central air conditioner with a 0.8 SHR rating will prioritize 80% of its capacity to cooling a home and 20% to removing excess humidity or moisture. The HVAC contractors near you at Snell Heating & Air Conditioning will select a system with an SHR rating that fits your home while performing the central air conditioning installation project.
