Get answers to common questions about hvac services in Naperville, Illinois.
For a standard efficiency, properly sized system, full replacement in Naperville typically ranges from $5,000 to $12,000+, depending on the unit's capacity (tonnage/BTU), efficiency rating (SEER2/AFUE), and complexity of installation. Illinois' 6.25% sales tax applies, and costs can be higher for premium variable-speed models or if ductwork modifications are needed for our older, historic neighborhoods. Always get itemized estimates from multiple licensed local contractors.
The optimal times are during the mild shoulder seasons: early spring (March-April) before the humid summer, and early fall (September-October) before the cold winter. Scheduling during these periods ensures you avoid the peak demand of July/August and December/January, leading to better availability, potential off-season discounts, and prevents emergency breakdowns during our most severe weather.
Yes. Naperville follows the Illinois Plumbing License Law and requires HVAC contractors to be licensed. Importantly, ComEd and Nicor Gas offer significant rebates for Naperville homeowners who install high-efficiency heat pumps, air conditioners, and furnaces. Additionally, the state of Illinois has sales tax exemptions on certain Energy Star equipment, making upgrades more affordable.
Prioritize companies that are locally established, licensed, insured, and have strong reviews on Naperville-focused platforms. They should perform a Manual J load calculation specific to our climate to correctly size your system, not just match the old unit's size. A trustworthy provider will also be familiar with local building codes and the specific challenges of our older home foundations and attic configurations.
During extreme heat and humidity, which is common here, it is normal for your system to run in longer cycles to maintain temperature and dehumidify. However, if it runs non-stop without reaching the thermostat setting, it indicates a problem like low refrigerant, a dirty coil, or an undersized unit. Given our climate, consistent over-cycling significantly increases wear and energy costs, warranting a professional evaluation.
