Your HVAC units are among the most dependable major appliances in your home, as your HVAC system monitors and regulates your interior air 24 hours a day regardless of the season. In most cases, your AC and heater run smoothly without fail so long as you keep them well-maintained with routine visits from an air-conditioning service. However, even the most reliable AC unit will struggle to function optimally when it’s improperly sized relative to the square footage of your home.
While most symptoms of an improperly sized AC unit wouldn’t warrant the attention of a provider with emergency air-conditioning repair in Gainesville, GA, they can cause your unit to run inefficiently, which can take a toll over time. Also, an improperly sized AC unit can keep your energy bills elevated, since your unit may run overtime to keep temperatures in check. There are many problems that can be caused by a unit that’s too large or too small for your square footage. Keep reading to learn more about those problems and how they can be avoided through proper AC unit selection.
Short cycling is a term to describe what happens when your air conditioner is too large for the space you need it to cool. Because it’s so powerful, your unit will cycle on, then quickly cool the air. Once the target temperature is reached, the unit will cut off. While this sounds like it shouldn’t be a problem, it can lead to reduced humidity removal that results in interior dampness. It can also lead to air quality issues because the unit doesn’t pull air through the filter for long enough to adequately remove dust and pathogens. Also, short cycling puts additional stress on your unit because it’s less efficient and at an increased likelihood of breaking down.
Constantly Running AC Unit
The converse of short cycling occurs when your AC unit is too small and underpowered for the space you’re asking it to cool. While you may think you’re saving money by purchasing a smaller AC unit, you’ll end up spending more in the long run when you buy too small for your space. A small, underpowered air conditioner will have to run constantly to hold the desired temperature, if it can even get to the desired temperature at all. That means your AC’s lifespan will be directly impacted, and the increased wear of constant cycling will result in additional repairs that can become costly.
Higher Energy Bills
Whether your AC unit is too small or too large, you’ll be spending more on energy bills with an improperly sized AC unit. If the unit is too small, it will run all the time and drive energy bills increasingly higher. If the unit is too large, it’ll needlessly consume additional power just to cycle on and run, which will prevent it from reaching its maximum efficiency potential.
If your unit is undersized, it’ll struggle to cool the air to the desired temperature no matter how hard it works. It will also be unable to properly remove the humidity from the air, which won’t impact the actual temperature but will affect your comfort level in the home since moisture in the air can make temperatures feel more oppressive. If the unit is too large, it may infrequently cycle on, meaning that, in between cycles, you may be uncomfortable. Also, short cycling overpowered AC units can’t run long enough to remove humidity from the air, which impacts overall comfort.
If you’re planning to install a new AC unit, make sure to consult with HVAC professionals about what size will perfectly meet the needs of your square footage.
