Constant cycling can create excessive wear on critical components, pushing repair needs beyond simple fixes.
Homeowners who choose proactive HVAC unit replacement reduce the risk of emergency breakdowns during peak heating or cooling seasons. New technology introduced within the last decade has significantly raised the baseline Seasonal Energy Efficiency Ratio (SEER) and Heating Seasonal Performance Factor (HSPF) of equipment available on the market. Increased efficiency equates to lower month-to-month energy consumption and reduced greenhouse gas emissions. Moreover, advancements in variable speed motors and smart thermostats allow finer control over indoor temperature, humidity, and airflow, creating a more comfortable environment with less equipment noise.
Delaying replacement can also create compatibility issues with environmentally friendly refrigerants.
