Get answers to common questions about hvac services in Big Rock, Illinois.
In Big Rock and the surrounding Kane/Kendall County area, a full HVAC system replacement typically ranges from $5,000 to $12,000+. Key cost factors include the system's size (tonnage/BTUs) required for our humid summers and cold winters, the unit's efficiency rating (SEER2 and AFUE), and the complexity of your home's ductwork. Prices also vary based on the brand and any necessary ancillary work, like updating electrical service or duct modifications.
The optimal times are during the shoulder seasons—early spring (March-April) before AC demand hits and early fall (September-October) before furnace season begins. Scheduling during these periods ensures you get prompt service from local contractors before the extreme summer heat or winter cold, which cause high-demand backlogs. This timing also allows you to test your system under mild conditions before it's critically needed.
While Big Rock itself doesn't have unique municipal codes, installations must comply with Illinois state mechanical codes and Kane County permits. Importantly, you should inquire about current utility rebates from providers like ComEd or Nicor Gas for installing high-efficiency equipment. Additionally, federal tax credits for qualifying ENERGY STAR® systems can provide significant savings, making higher-efficiency models more affordable upfront.
Prioritize local, established contractors with strong community reputations, verified Illinois HVAC licenses, and proper insurance. Ask for references from homes of similar age in the area, as older Big Rock homes may have specific needs. Essential questions include: "Are you familiar with the water table and basement humidity issues common in our region for installing/hooking up humidifiers?" and "Do you provide a detailed, written estimate that includes load calculations (Manual J) for our specific climate zone?"
During extreme cold spells common in Illinois, where temperatures can stay below freezing for days, it's normal for a properly sized furnace to have longer run cycles to maintain temperature. However, if it's running non-stop without reaching the thermostat setting, it could indicate issues like a dirty filter, failing components, or an undersized system. Given our harsh winters, consistent problems warrant a professional diagnostic to ensure safety, efficiency, and prevent a mid-winter breakdown.
