Get answers to common questions about hvac services in Janesville, Wisconsin.
For a full system replacement in Janesville, homeowners can expect to pay between $5,000 and $12,000+, depending on the system's efficiency (SEER for AC, AFUE for furnace) and home size. Wisconsin's cold winters make high-efficiency furnaces (90%+ AFUE) a popular, cost-saving choice long-term. Always get multiple itemized quotes from local, licensed contractors, as labor costs and home-specific challenges (like older ductwork in historic Janesville homes) can affect the final price.
The ideal times are during the shoulder seasons—spring (March-May) for AC service and fall (September-October) for furnace service. Scheduling during these periods ensures your system is ready for Janesville's humid summers and harsh, sub-zero winters, and you'll avoid the high-demand rush when emergency repairs are more costly and less available. For replacements, planning in the off-season often provides more installer availability and potential promotional pricing.
Yes. Wisconsin requires that all HVAC contractors performing more than $1,000 of work be licensed as a Dwelling Contractor Qualifier. Additionally, Focus on Energy, Wisconsin's statewide energy efficiency and renewable resource program, frequently offers rebates for installing high-efficiency HVAC equipment, which can significantly offset costs. It's also wise to check with your local utility, like Alliant Energy or Rock Energy Cooperative, for any Janesville-specific incentives.
Prioritize local, established companies with strong community reputations, proper Wisconsin licensing, and insurance. Look for NATE-certified technicians, which indicates advanced training. Read verified local reviews (Google, BBB) and ask for references in Janesville neighborhoods similar to yours. A trustworthy contractor will perform a detailed load calculation (Manual J) for your specific home, not just recommend a unit size based on square footage alone.
This depends on the furnace's age, efficiency, and repair history. If your furnace is over 15 years old, has an AFUE rating below 80%, or requires frequent repairs, a pre-winter replacement is a wise investment for reliability and efficiency. A sudden failure during a January cold snap in Janesville can be dangerous and lead to costly emergency service calls. A professional assessment can help you weigh the cost of a new system against the risk and expense of an older unit.
