We completed a comprehensive mechanical system upgrade for this Orland Park residence, replacing the aging heating, cooling, and water heating equipment. Our team installed a high-efficiency Lennox gas furnace and a matching central air conditioning condenser to provide reliable year-round comfort. We also integrated a new Bradford White water heater and a whole-home humidifier to modernize the entire utility space. The installation required precise configuration of new PVC venting and updated copper refrigerant lines to meet current efficiency standards. We performed detailed electrical testing on all new components, including capacitors and inducer motors, to ensure peak operational performance. These upgrades significantly improve the home's energy efficiency and provide the owners with long-term peace of mind regarding their essential systems.
