Get answers to common questions about hvac services in Frankfort, Illinois.
In Frankfort, a full HVAC system replacement typically ranges from $6,500 to $12,000+, depending on the system's size (measured in tons for AC and BTUs for furnace), efficiency rating (SEER2 for AC, AFUE for furnace), and brand. Key local factors include the need for equipment rated for our humid Midwest summers and cold winters, potential ductwork modifications common in older Frankfort homes, and compliance with Illinois state codes and local Will County permit requirements, which can affect labor costs.
The ideal times are during the mild shoulder seasons—early spring (March-April) before AC demand hits and early fall (September-October) before heating season begins. Scheduling during these windows ensures you avoid the peak summer and winter rush when local HVAC companies are busiest with emergency repairs. This timing also allows for thorough system testing before you need it most for Frankfort's hot, humid summers and freezing winters.
Yes, Frankfort homeowners should check for current rebates from utility providers like Nicor Gas and ComEd, which often offer incentives for installing high-efficiency furnaces, air conditioners, and heat pumps. Additionally, federal tax credits for qualified energy-efficient home improvements are available. It's crucial to work with a local HVAC provider familiar with these programs, as they can help ensure your selected equipment qualifies and assist with the paperwork.
Always choose a contractor who is licensed, insured, and has a strong physical presence in the Frankfort/Will County area. Verify they hold an active Illinois HVAC License and check for positive reviews on local community pages. A reputable local contractor will understand the specific needs of our climate, be familiar with local building codes, and should offer a detailed, written estimate that includes any potential challenges common to Frankfort homes, such as servicing older systems or navigating tight attic or basement spaces.
During extreme heat and humidity, which is common here, it is normal for your AC to run in longer cycles to maintain your set temperature and manage humidity levels. However, if it runs non-stop without adequately cooling your home or if your energy bills spike disproportionately, it could indicate an issue like low refrigerant, a dirty coil, or an undersized unit. Given our climate, scheduling a pre-summer tune-up is the best way to ensure your system can handle the seasonal demand efficiently.
