Get answers to common questions about hvac services in Mount Vernon, Illinois.
For a standard efficiency, properly sized system, full replacement in Mount Vernon typically ranges from $5,000 to $12,000, depending on the unit's capacity (measured in tons or BTUs) and efficiency rating (SEER/HSPF). Southern Illinois's humid summers and cold winters mean proper sizing is critical, and local labor rates, along with potential ductwork modifications for older homes, significantly influence the final price. Always obtain itemized estimates from multiple licensed local contractors.
The optimal times are during the mild shoulder seasons—early spring (March-April) for your cooling system and early fall (September-October) for your heating system. Scheduling during these periods ensures your system is ready for Mount Vernon's peak summer heat and humidity and the freezing winter temperatures, while also providing better availability and potential off-season promotional pricing from local HVAC companies.
Yes, HVAC contractors in Illinois must be licensed by the Illinois Department of Public Health (IDPH). In Mount Vernon, you will likely need a local building permit for a full system replacement, which ensures the installation meets current building and mechanical codes. Furthermore, proper disposal of old refrigerant (like R-22) is federally mandated; a reputable local contractor will handle this and provide documentation.
Prioritize contractors who are locally established, fully licensed, insured, and have positive reviews from Mount Vernon residents. Ask for references from homes of similar age and system type, as older homes here may have unique ductwork challenges. Verify they perform a Manual J load calculation specific to our regional climate to ensure correct sizing, rather than just matching your old unit's capacity.
During extreme Southern Illinois heat and humidity, it is normal for your AC to run in longer cycles to maintain temperature and remove moisture. However, if it runs non-stop without adequately cooling your home, it indicates a problem like low refrigerant, a dirty coil, or an undersized unit. Given our climate, this inefficiency leads to exorbitant energy bills and requires prompt diagnosis by a local technician.
