As summer temperatures rise, 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.
Importance of Proper Sizing
Consumer Reports notes that air conditioners are tested under extreme conditions to evaluate cooling performance, energy efficiency, and usability. 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.
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 the number of windows, insulation, and the overall climate of the area. Considering these variables can help ensure a more accurate cooling capacity selection.
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.
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 inverter technology and smart sensors, which can help reduce electricity usage while maintaining consistent indoor comfort.
