Get answers to common questions about hvac services in Dover, Illinois.
For a standard efficiency, properly sized system, full replacement costs in the Dover area typically range from $5,000 to $12,000, depending on the unit's capacity and efficiency (SEER/AFUE ratings). Our Illinois climate, with hot, humid summers and cold winters, means systems work hard, so investing in a mid-to-high efficiency model often provides better long-term value and comfort. Always get a detailed, written estimate that includes removal of the old unit, new installation, and all necessary permits.
The ideal times are during the shoulder seasons—early spring (March-April) for your AC and early fall (September-October) for your furnace. Scheduling during these periods ensures your system is ready for the peak summer heat and winter cold, and you'll find greater technician availability and potentially better pricing than during the emergency-driven summer and winter months. This is critical in Illinois where temperature swings can be sudden and severe.
Yes, while Dover itself may not have unique codes, all work must comply with the Illinois Plumbing License Law and local building codes, which require permits for new installations and major modifications. Furthermore, Illinois homeowners should check for current utility rebates from providers like Ameren Illinois for upgrading to high-efficiency equipment, and federal tax credits for qualifying systems, which can significantly offset your investment.
Look for a locally established, licensed, and insured contractor with strong references from Dover or nearby communities like Peru or LaSalle. Verify they carry proper liability insurance and that their technicians are NATE-certified. A trustworthy provider 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.
During extreme cold snaps 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 constantly running without reaching the thermostat setting, it could indicate issues like a dirty filter, failing components, or an undersized system. A professional evaluation can determine if it's a repair need or simply the harsh winter demand.
