Case Study: Enhanced Comfort in Steeplechase

A recent project brought us to a beautiful, mid-century colonial home in Oak Brook's Steeplechase neighborhood. The homeowner was contending with an original furnace and air conditioner, struggling to maintain consistent temperatures across their multi-story residence, especially during extreme Chicago weather. Our project management approach began with a detailed assessment of their existing ductwork, insulation, and energy consumption patterns.

We then coordinated the complete HVAC replacement, removing the outdated system and installing a new, high-efficiency two-stage furnace and a matching air conditioning unit. Our trade partners ensured all connections, including the Nicor Gas line for the furnace, were updated and thoroughly inspected. The new system was meticulously balanced to deliver even heating and cooling throughout the entire home. The homeowners now enjoy superior indoor air quality, significantly reduced energy bills, and quiet, reliable comfort in every room, making their Steeplechase home even more enjoyable year-round.
