Get answers to common questions about hvac services in Granite City, Illinois.
For a standard efficiency, properly sized system, full replacement costs in Granite City typically range from $5,000 to $12,000, depending on the unit's capacity (measured in tons or BTUs) and efficiency rating (SEER/HSPF). Local factors like our humid summers and cold winters mean proper sizing is critical, and prices can be influenced by Illinois state sales tax and any available ComEd or Ameren utility rebates for high-efficiency models. Always get a detailed, in-home estimate that includes load calculations.
The ideal times are during the mild shoulder seasons—early spring (March-April) before the intense summer heat and humidity arrive, and early fall (September-October) before winter's freezing temperatures. Scheduling during these periods ensures your system is ready for peak demand and provides much greater availability and potential scheduling flexibility with local HVAC companies compared to the middle of a heatwave or cold snap.
Yes. In Illinois, HVAC contractors must be licensed by the Illinois Department of Public Health (IDPH). Additionally, for any work involving refrigerants (like AC repairs), technicians must be EPA Section 608 certified. Locally, the City of Granite City may require permits for new system installations or major replacements; a reputable local contractor will handle this permitting process for you to ensure all work is up to current building and mechanical codes.
Prioritize local, established companies with strong community reputations. Verify their Illinois state license and insurance, ask for references from Granite City neighbors, and check reviews specific to their service in the Metro East area. A trustworthy contractor will perform a Manual J load calculation for your specific home to ensure proper sizing, offer clear written estimates, and discuss options suited to our local climate, such as variable-speed systems for better humidity control.
For cooling, the most common issue during our humid summers is a dirty or clogged air filter, which severely restricts airflow and reduces cooling capacity and dehumidification. For heating, ensure your exterior exhaust and intake vents (for high-efficiency furnaces) are not blocked by snow, leaves, or debris, which is a frequent winter occurrence here. Always check these simple items before calling for service, as they are often the culprit.
