Get answers to common questions about hvac services in Wilmette, Illinois.
For a standard efficiency replacement in a Wilmette home, expect a range of $4,500 to $7,500 for a furnace and $5,000 to $8,500 for an air conditioner. Higher-efficiency models (like 96%+ AFUE furnaces or 18+ SEER ACs) will be at the top end due to advanced components and the skilled labor required for proper installation. Local factors like the age of your home's ductwork and the specific brand/model selected will also influence the final price.
The ideal times are during the shoulder seasons—late spring (April-May) for AC service and early fall (September-October) for furnace service. Scheduling during these periods ensures your system is ready for Wilmette's humid summers and cold, snowy winters, and you'll avoid the high-demand rush periods where wait times are longer. For replacements, planning ahead during these windows often provides more installer availability and potential promotional pricing.
Yes. Wilmette 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 line work connected to a furnace installation, the contractor must often coordinate with Nicor Gas. It's also important to check if your home is in a local historic district, as exterior condenser placement may have specific aesthetic guidelines.
Look for a provider with a strong, long-standing local reputation in Wilmette and the North Shore, as they understand the specific housing stock and climate challenges. Verify they are fully insured, hold the required Illinois and local licenses, and offer clear, written estimates. Check reviews on independent platforms and ask for references from homes similar in age and style to yours to gauge their experience.
This is common in historic and older homes here. Before considering a full system replacement, a professional energy audit or HVAC assessment can identify key issues. Solutions often include sealing and insulating leaky ductwork in attics or crawlspaces, adding attic insulation, and addressing window drafts. For the system itself, a properly sized multi-stage furnace or a zoning system can significantly improve comfort by providing more consistent, modulated heating and cooling.
