Choosing the Right Size for Your New Air Conditioner: Does It Matter?

Posted: 2023-05-18

With summer just a few weeks away, the importance of your air conditioner cannot be overstated. While it may not be what you want to hear, the truth is that your AC unit is not designed to last indefinitely. Ideally, it should deliver optimal comfort throughout your home while being energy-efficient. Moreover, it should effectively reduce humidity levels, which only adds to the discomfort of summer heat. Additionally, it should be capable of lowering the temperature enough to ensure a good night's sleep or enable you to carry out your daily tasks comfortably.

Even with proper maintenance, there may come a time when your AC system no longer meets your family's cooling needs, particularly during the hottest parts of summer.

If you're currently in the market for a new air conditioner, your search ends here. Four Seasons Air Specialists is the leading HVAC company in Woodbury MN, offering a diverse range of energy-efficient air conditioners manufactured by top industry professionals.


When it comes to air conditioners, bigger and more expensive does not always mean better. Selecting the right cooling system requires careful consideration of proper sizing, rather than simply relying on advertised features. Many homeowners make the mistake of choosing an air conditioner without assessing its appropriate size.

Importance of Proper Sizing

Selecting the proper size involves determining the cooling power required for your home. This process cannot rely on estimation or guesswork. It entails evaluating your home's cooling needs to determine the ideal power capacity for the air conditioner. Proper sizing is crucial because an incorrectly sized AC unit will inevitably lead to problems down the line.

Evaluation Process

A qualified technician will conduct a comprehensive survey of your home to assess its ability to prevent heat from entering and identify any heat retention issues. This evaluation enables the technician to determine the appropriate level of air conditioning required to address the heating problem. Factors considered during this assessment may include:

- Size and architectural layout of the house
- Type, number, and orientation of windows
- Type and quality of insulation
- Number of occupants
- Amount of heat generated by lights and heat sources
- Regional weather conditions

Based on a thorough analysis of these factors, the technician will provide a definitive recommendation regarding the size of air conditioner needed for your home. By following this recommendation, you can enjoy maximum comfort while minimizing energy waste and extending the lifespan of the unit.

Impact of Improperly Sized AC:

If your air conditioner is improperly sized for your home, it can lead to several issues. When the AC unit is too small, it struggles to reach your desired cooling level. As a result, it runs for extended periods, causing the compressor to work harder and consume more energy. This not only shortens the lifespan of the system but also creates hot and cold spots in your home. Certain rooms may remain warm due to the insufficient cooling power, especially if they have large appliances or east/west-facing windows that contribute to heat sources. Ultimately, installing an incorrectly sized air conditioner means you'll have to replace it much sooner. Similarly, an oversized AC unit poses similar problems.

Benefits of a Properly Sized AC:

On the other hand, a properly sized cooling system brings several advantages. It cools your home more efficiently and effectively, reducing energy consumption and subsequently lowering your monthly bills. Moreover, maintenance costs are minimized as the system operates optimally. With the right-sized AC, your home remains comfortable even during scorching summer days. Furthermore, a properly sized air conditioner operates smoothly, adhering to the manufacturer's specifications and minimizing excessive noise, ensuring a peaceful living environment.
