Get answers to common questions about hvac services in Dekalb, Illinois.
For a standard efficiency, single-stage system, full replacement costs typically range from $5,000 to $9,000 for an air conditioner and $4,500 to $8,500 for a furnace. Dekalb's climate, with hot, humid summers and cold winters, often necessitates robust systems, and prices can be influenced by regional labor rates and the complexity of your home's ductwork. Always get multiple itemized quotes from local, licensed contractors to ensure a fair price.
The optimal times are during the mild shoulder seasons—early spring (March-April) for AC tune-ups and early fall (September-October) for furnace check-ups. Scheduling during these periods ensures your system is ready for peak demand and provides the best availability with local HVAC companies. Avoid the first major heat wave or cold snap, as service calls are at their highest and emergency rates often apply.
Yes. While Illinois state mandates have phased out R-22 refrigerant, a key local consideration is checking for current rebates from your utility provider, such as Nicor Gas or ComEd, for installing high-efficiency equipment. Additionally, Dekalb County may have specific permit requirements for new installations or major replacements, which a reputable local contractor will handle for you.
Prioritize contractors who are licensed, insured, and have strong local references. Look for established companies familiar with Dekalb's older home stock and the specific challenges of our soil conditions, like basements, which can affect humidification needs. Check their ratings on the Better Business Bureau and ensure they perform a detailed load calculation (Manual J) before proposing any new system.
During sustained sub-freezing temperatures common in Northern Illinois, it's normal for a properly sized furnace to have longer run cycles to maintain temperature. However, if it's cycling on and off every few minutes (short-cycling) or struggling to reach the thermostat setting, it could indicate issues like a dirty filter, failing component, or an undersized system. Have a local technician perform a diagnostic to ensure safety and efficiency.
