- How prolonged low temperatures impact furnace combustion and heat-pump performance
- The need for high-efficiency air conditioning (SEER ratings) to handle summer humidity without oversized equipment
- Indoor air quality concerns from seasonal pollen, basement dampness, and tightly sealed homes
- Commercial load balancing for retail and office spaces around Oakbrook Center and the business corridors
