Get answers to common questions about hvac services in Winnetka, Illinois.
For a full system replacement in Winnetka, homeowners can expect to pay between $5,000 and $12,000+, depending on the system's efficiency, size (tonnage/BTU), and complexity of installation. Our region's significant temperature swings demand reliable, high-efficiency equipment (like 16+ SEER AC or 95%+ AFUE furnaces), which are a worthwhile investment for long-term comfort and energy savings, especially given ComEd's seasonal rates.
The optimal times are during the mild shoulder seasons—early spring (March-April) for AC service and early fall (September-October) for furnace service. Scheduling during these periods ensures your system is ready for our hot, humid summers and cold, snowy winters, and you'll have better availability from local technicians compared to the peak seasonal rush.
Yes. Winnetka requires HVAC contractors to be licensed, and the State of Illinois mandates that technicians handling refrigerants be EPA Section 608 certified. Furthermore, for any gas furnace installation, the work must be permitted and inspected by the Village's Building Department to ensure it meets all current safety and building codes, which is a critical step for your protection.
Look for a locally established company with strong, verifiable reviews from other Winnetka residents. Ensure they are fully licensed, insured, and offer detailed, written estimates. A trustworthy provider will perform a Manual J load calculation specific to your home's construction (common in older Winnetka homes) to correctly size the system, not just replace it with the same size unit.
This is common in historic North Shore homes. Before considering a full system replacement, invest in a professional energy audit and duct assessment. Sealing leaky ducts, adding insulation, and addressing air infiltration are often the most cost-effective first steps. For comfort, a zoning system or a ductless mini-split for hard-to-condition additions can be excellent solutions tailored to our climate.
