Why Does The Size of Your AC Matter?

Installing a new air conditioning unit is a lengthy process that requires carefully considering various factors. These factors directly impact the homes comfort levels and include the following:  

  • The size required for the unit
  • Efficiency rates
  • Type of air conditioning (central vs. ductless multi-split)
  • Noise levels produced by the AC
  • Brand and reliability of the unit
  • Installation and maintenance costs 

This blog will discuss the importance of selecting an air conditioning unit that is perfectly sized for your home. Contact One Source, the top Colorado Springs AC installation crew, for help determining the right size for your new AC. 

Appropriate Size Ensures the Following for Your Home

Professional HVAC installers begin the cost estimation process for installing a new air conditioning unit by determining the appropriate size needed to cool and heat your home efficiently. This is done by following these steps: 

  1. Gathering all the needed information like the square footage, layout, and construction details. They may also inquire about the insulation details and the number of doors and windows in the home. 
  2. Conducting a Manual J Calculation is an industry-standard method that determines residential buildings’ heating and cooling loads. 
  3. Evaluating heat gain and loss by calculating factors such as solar radiation through windows, heat transfer through walls and ceilings, and infiltration rates.
  4. Assessing the zoning layout and ductwork design.
  5. Selecting the appropriate AC system based on the SEER (seasonal energy efficiency ratio) and the type of system required, whether it’s a heat pump, central AC, or a multi-split air conditioning unit. 

Here is why Colorado Springs’ AC installation techs take this process very seriously:

A Comfortable Atmosphere

“I’m okay with being uncomfortable in my home,” said no one ever. For this reason, the size of the must be in direct proportion to your home’s square footage, insulation quality, and other factors. If your AC is too big, it will cool your home too quickly and shorten the cycle. If the unit is undersized, it won’t keep up with the cooling and heating demands, causing you to always be hot or cold, depending on the season. 

Optimal Energy Efficiency 

It is vital that your air conditioning unit is as efficient as possible, and the size of your unit will impact those efficiency levels. If the AC is too small for the home, it will consume more energy. If it is too big, it will cause the AC to turn on and off too frequently, increasing wear and tear on the unit. To ensure that your AC works at optimal efficiency levels, the AC must be the correct size.

Prolonged Lifespan

The size of your AC unit will dictate the lifespan of your air conditioning unit. Whether the unit is oversized or undersized, it will wear out quicker than usual and must be replaced earlier. A properly sized AC unit operates within its intended capacity, leading to better reliability and a longer lifespan.

Good Indoor Air Quality

Oversized units cool the space quickly but don’t run long enough to effectively remove moisture from the air, leading to high humidity levels. High humidity can create a breeding ground for mold, mildew, and other allergens, negatively impacting the air quality. Undersized units may struggle to adequately circulate and filter the air, affecting the removal of pollutants and allergens.


When your AC is sized appropriately, you save money monthly and annually. After all, your AC will work as smoothly as possible while consuming minimum energy levels. As a result, your energy bills will be low, and your repair costs won’t be as high or as frequent.
