Get answers to common questions about hvac services in Markham, Illinois.
For a standard efficiency replacement in Markham, homeowners can expect to pay between $4,500 to $8,500 for a new air conditioner and $4,000 to $7,500 for a new furnace, with high-efficiency models costing more. Final costs depend heavily on home size, unit capacity, and installation complexity. Given Illinois' volatile energy prices, investing in a higher SEER or AFUE-rated system can offer significant long-term savings on utility bills, and local providers often offer financing options.
The ideal times are during the shoulder seasons—spring (March-May) for AC service and fall (September-November) for furnace service. Scheduling during these periods ensures your system is ready for Markham's hot, humid summers and cold, snowy winters, and you'll avoid the high-demand rush and potential emergency fees. For replacements, planning ahead in these windows also provides better availability and often more flexible scheduling with local contractors.
Yes, all HVAC contractors in Markham must be licensed by the State of Illinois and should pull the required local permits for major installations. Homeowners should verify this with their chosen provider. For rebates, check with utility providers like Nicor Gas and ComEd, which frequently offer incentives for upgrading to high-efficiency equipment, and the State of Illinois may also have applicable sales tax holidays on Energy Star-rated appliances.
Always verify an Illinois state license, insurance, and check for local reviews or references from neighbors. A reputable Markham-area contractor will perform a detailed Manual J load calculation specific to your home's construction and our local climate, not just recommend the same size as your old unit. Be wary of quotes given over the phone without an in-home assessment, as proper sizing is critical for efficiency and comfort.
Proactive replacement is often wiser, especially with Markham's harsh winters where a sudden failure can be dangerous. Older furnaces (15+ years) operate at much lower efficiencies (e.g., 70-80% AFUE) compared to modern units (90%+ AFUE), wasting significant money on Nicor gas bills. Scheduling a replacement on your terms allows for careful selection, avoids emergency service premiums, and ensures you are not left without heat during a cold snap.
