When it’s time to install a new HVAC unit in your St. Louis, MO, home, purchase one that’s the right size. This is a Goldie Locks situation. If you get one that’s too small, it won’t be powerful enough to regulate the interior temperatures of your home. However, if your HVAC unit is too large, it won’t operate as efficiently as it should. In this case, it’ll wear out faster. Here’s what to consider when purchasing a new HVAC system:

Know the Square Footage of Your Home

Before buying an HVAC system, measure the square footage of your home. This information will likely be listed on your blueprints. If you don’t have it, you might have to measure it yourself. Use a tape measure to determine the length and width of each room. Then, multiply those two numbers together to get the square footage of the space. For the total square footage, add them together.

Figure out the Base BTU

HVAC companies use an energy measuring unit called the British Thermal Unit, or BTU, to determine how much energy is needed to heat and cool a home. According to experts, 25 BTUs are needed to cool one square foot in a home.

Consider Features of Your Home

When sizing an HVAC unit, consider features of your home like the height of your ceilings, the number of windows that you have and your landscaping. If you have ceilings that are more than 8 feet tall, multiply your base BTU figure by 25%. Also, consider how many windows you have and whether your landscaping includes enough trees to cool your home naturally.

Leave It to the Professionals

To ensure that you purchase an AC system that’s properly sized, bring in the professionals. They use a specific calculation method that factors in your home’s many elements to determine the right unit size.
