The Lead Off
- Consumer Reports says selecting the correct air conditioner size can improve comfort and reduce energy costs during summer heat.
- Oversized or undersized units may lead to humidity issues, higher bills, or inefficient cooling performance.
- Experts recommend proper sizing, regular filter maintenance, and sealing window units for best results.
INDIANAPOLIS, IND. (WOWO) As summer temperatures rise across Indiana, Consumer Reports is advising consumers to pay close attention to air conditioner size and maintenance in order to stay comfortable and control energy costs.
Experts with Consumer Reports say one of the most common mistakes homeowners make is selecting an air conditioning unit that does not match the size of the space being cooled.
Proper sizing affects comfort and efficiency
Consumer Reports notes that air conditioners are tested under extreme conditions to evaluate cooling performance, energy efficiency, and usability.
According to experts, an oversized unit may cool a room too quickly, shutting off before it has properly removed humidity from the air. This can leave indoor spaces feeling cold and damp rather than comfortable.
An undersized unit, however, may run continuously in an effort to keep up with demand during high temperatures, leading to higher energy consumption and reduced cooling effectiveness.
Factors to consider before purchasing
Before buying a new air conditioner, Consumer Reports recommends carefully measuring the space and reviewing manufacturer sizing guidelines.
Additional factors that can influence the appropriate unit size include:
- Ceiling height
- Amount of direct sunlight entering the room
- Number of occupants regularly using the space
- Room layout and insulation quality
Experts say considering these variables can help ensure a more accurate cooling capacity selection.
Maintenance plays key role in performance
Consumer Reports also emphasizes that regular maintenance can significantly improve air conditioner performance and longevity.
Homeowners are advised to clean or replace filters according to manufacturer instructions. Dirty filters can restrict airflow, causing the system to work harder and potentially increasing energy costs.
For window units, sealing gaps around the installation is also important to prevent warm air from entering and cool air from escaping.
Energy-saving features highlighted
Consumer Reports testing identified several models with strong performance ratings, including the LG LW8024IVSM and Mitsubishi HM Series MZ-HM12NA.
Experts also point to energy-saving features such as:
- Programmable thermostats
- Sleep modes
- Energy Star certification
These features can help reduce electricity usage while maintaining consistent indoor comfort.
Next steps for consumers
As peak summer heat continues, Consumer Reports recommends that consumers evaluate both current systems and potential upgrades to ensure their cooling systems are properly sized and maintained. The organization says making informed choices can help reduce energy costs while improving indoor comfort throughout the season.
The Takeaway
- Consumer Reports emphasizes that selecting the correct air conditioner size is critical, as units that are too large or too small can reduce efficiency and comfort.
- Proper maintenance, including filter cleaning and sealing window units, can improve performance and help lower energy bills during peak summer months.
- Energy-efficient features and careful room assessment can help consumers make more cost-effective cooling decisions as temperatures rise.
