Get answers to common questions about hvac services in FDL, Wisconsin.
In Fond du Lac, a full furnace replacement typically ranges from $4,500 to $8,500+, depending on the unit's efficiency (AFUE rating), size, and complexity of installation. Given our cold Wisconsin winters, investing in a high-efficiency model (90%+ AFUE) is often recommended for long-term savings. Locally, you should check for rebates from Focus on Energy, Wisconsin's statewide energy program, and inquire with FDL utilities like Fond du Lac Utilities for any additional incentives for upgrading to efficient equipment.
The ideal times are during the shoulder seasons—late spring (April-May) after heating season and early fall (September-October) before heating season begins. Scheduling during these periods ensures your system is ready for Fond du Lac's harsh winters and humid summers, and you'll find greater technician availability and potentially better pricing compared to the peak summer AC rush or winter emergency furnace repair season.
Yes, all HVAC work in Fond du Lac must comply with Wisconsin's Uniform Dwelling Code (UDC) and may require specific permits from the City of Fond du Lac's Inspection Department. A reputable local contractor will handle this, but it's crucial to verify they are licensed and will pull the proper permits. This ensures safety, compliance with energy efficiency standards relevant to our climate, and protects your home's value.
Look for a locally established company with strong community reviews and verifiable licensing (Wisconsin HVAC license). They should perform a detailed Manual J load calculation specific to your home, as older Fond du Lac homes have unique insulation and air leakage challenges. Always get multiple written estimates, and prioritize contractors who offer comprehensive service plans to maintain your system against our demanding seasonal shifts.
No, refrigerant is not consumed; a low level indicates a leak that must be repaired by a licensed technician. Simply adding refrigerant is illegal under EPA regulations and won't solve the root problem. The issue could also be an undersized unit, poor airflow, or a failing component. Given our summer humidity, a proper diagnosis is essential for both comfort and efficiency.
