When it comes to staying cool during the summer months, having the right size air conditioner is essential. However, with so many options available in the market, choosing the right size can be a daunting task. A unit that is too small will not be able to cool your home efficiently, while one that is too large will result in unnecessary expenses and energy waste.
In this comprehensive guide, we will take you through the steps of choosing the right size air conditioner for your home, so you can beat the summer heat without breaking the bank.
Step 1: Calculate the Square Area of Your Home
The first step in choosing the right size air conditioner for your home is to determine the square footage of the area you want to cool. To do this, measure the length and width of each room you want to cool, then multiply these numbers to get the total square footage of the room. Once you have the square footage of each room, add them together to get the total square footage of your home.
Step 2: Determine the Cooling Capacity Needed
Once you have the total square footage of your home, you need to determine the cooling capacity needed. Cooling capacity is measured in British Thermal Units (BTUs) per hour. The rule of thumb is that you need 20 BTUs per square foot of living space. However, this rule may not apply to all situations.
Factors that may affect the cooling capacity needed include:
Number of windows
Type of roof
Number of occupants
To get a more accurate estimate of the cooling capacity needed, you can use an online calculator or consult with a professional HVAC contractor.
Step 3: Consider the Efficiency Rating
When choosing an air conditioner, it's important to consider its energy efficiency. The higher the Seasonal Energy Efficiency Ratio (SEER) rating, the more efficient the air conditioner is. A higher SEER rating means lower energy bills and a more environmentally friendly unit. The minimum SEER rating for new air conditioners is 13, but you can choose units with higher SEER ratings for greater efficiency.
Step 4: Choose the Type of Air Conditioner
There are several types of air conditioners available, each with its own set of pros and cons. The most common types of air conditioners include:
Window air conditioners: These units are designed to fit into a standard window and are suitable for cooling single rooms. They are affordable and easy to install, but they can be noisy and block the window view.
Portable air conditioners: These units can be moved from room to room and are ideal for renters or homeowners who do not want to install a permanent unit. They are also easy to install, but they can be noisy and less efficient than other types of air conditioners.
Central air conditioners: These units are the most expensive and require professional installation, but they provide the most efficient and effective cooling for your entire home. They are also the quietest and most visually appealing option.
Step 5: Consult with a Professional
Choosing the right size air conditioner is a complex process that requires careful consideration of several factors. Consulting with a professional HVAC contractor can help you make an informed decision and ensure that you choose the right size air conditioner for your home.
Choosing the right size air conditioner for your home is a critical decision that requires careful consideration of several factors. Calculating the square footage of your home, determining the cooling capacity needed, considering the efficiency rating, choosing the type of air conditioner, and consulting with a professional HVAC contractor are all crucial steps in this process.
By following these steps, you can ensure that you choose the right size air conditioner for your home, keeping you and your family cool and comfortable during the hot summer months while avoiding unnecessary expenses and energy waste. Don't let the heat get to you this summer – choose the right air conditioner and stay cool all season long.
