Energy Services Transforms Home Comfort: A Comprehensive HVAC Case Study in Naperville, IL


Energy Services, a leading HVAC company serving Naperville, Wheaton, Bolingbrook, Downers Grove, Lisle, and Aurora, IL, was approached by the Johnson family in Naperville. The Johnsons were experiencing inconsistent heating throughout their two-story home and were concerned about rising energy bills. They sought a solution that would provide reliable comfort and improved energy efficiency.


Upon inspection, Energy Services technicians identified several issues:

  • An outdated and inefficient furnace
  • Poorly insulated ductwork
  • Uneven heat distribution between floors
  • High energy consumption

The challenge was to design and implement a comprehensive heating solution that would address all these issues while staying within the family’s budget.


Energy Services proposed a multi-faceted approach:

1. Furnace Replacement: Installation of a high-efficiency, variable-speed furnace to replace the old unit.
2. Ductwork Improvement: Sealing and insulating existing ductwork to minimize heat loss.
3. Zoning System: Implementation of a two-zone system to allow independent temperature control for each floor.
4. Smart Thermostat: Installation of a programmable smart thermostat for optimized energy usage.

The Johnson family approved the proposal, and Energy Services proceeded with the implementation.


The project was completed over three days:

Day 1: The old furnace was removed, and the new high-efficiency unit was installed. Technicians began work on the ductwork improvements.

Day 2: Ductwork sealing and insulation were completed. The zoning system was installed, including dampers and additional wiring.

Day 3: The smart thermostat was installed and programmed. Final system checks and calibrations were performed.

Throughout the process, Energy Services technicians maintained clear communication with the Johnsons, explaining each step and addressing any concerns.


Six months after the project completion, the Johnsons reported significant improvements:

  • 30% reduction in energy bills
  • Consistent comfort throughout the home
  • Improved air quality
  • Greater control over temperature settings

The new zoning system allowed the family to maintain different temperatures upstairs and downstairs, catering to individual preferences. The smart thermostat’s learning capabilities further optimized energy usage based on the family’s habits.


This case study demonstrates Energy Services’ ability to provide comprehensive heating solutions tailored to specific client needs. By addressing multiple aspects of the home’s HVAC system, from furnace replacement to smart controls, Energy Services delivered a solution that significantly improved both comfort and energy efficiency.

The success of this project showcases Energy Services’ expertise in heating service, heater installation, furnace service, and furnace replacement across their service areas, including Naperville, Wheaton, Bolingbrook, Downers Grove, Lisle, and Aurora, IL. It underscores the company’s commitment to delivering customized, efficient, and effective HVAC solutions to homeowners in the region.
