Energy Efficiency Considerations

While the idea of reducing utility expenses often drives interest in HVAC replacement, understanding how efficiency ratings translate into real-world savings is essential.

SEER, EER, and AFUE Ratings

• SEER (Seasonal Energy Efficiency Ratio) measures cooling efficiency over an entire season—higher numbers indicate greater efficiency.
• EER (Energy Efficiency Ratio) evaluates cooling performance at specific outdoor temperatures, helpful for Sparta’s hottest afternoons.
• AFUE (Annual Fuel Utilization Efficiency) applies to furnaces, showing how much fuel converts into usable heat—an AFUE of 95% wastes only 5% of the gas consumed.

Variable-Speed Technology

Traditional single-stage systems blast at full power, then shut off. Modern variable-speed compressors and blower motors operated by advanced inverters scale output smoothly between low and high demand. Benefits include:

• Reduced energy spikes during start-up
• More stable indoor temperatures
• Quieter operation and better moisture removal

Duct Sealing and Insulation

An efficient unit can only do its job if conditioned air reaches every room. During replacement, HEP technicians inspect:

• Supply and return trunk lines for gaps or cracks
• Attic and crawlspace ducts for missing insulation
• Flex ductwork for kinks or compression that restrict airflow

Addressing these issues concurrently with equipment replacement amplifies overall energy gains and comfort improvements.
