A furnace that stops working on a Wisconsin winter night is an emergency — not a Tuesday-morning problem. JC Heating and Cooling has been repairing furnaces in Janesville and Rock County since 1997, and we've seen everything from ignitor failures to cracked heat exchangers to systems that just needed a new filter and a reset.
We service all gas furnace brands and tell you honestly what needs to be done. No upsells. No scare tactics. Just a real diagnosis from a technician who's been doing this for decades. Call or text (608) 752-2472 — we're here Monday through Friday, 8am to 4pm.

Frequently Asked Questions — Furnace Repair
Why is my furnace blowing cold air?
Usually a tripped limit switch, dirty filter blocking airflow, a pilot light or ignitor issue, or a problem with the gas supply. Check your filter first. If that's not it, call us — blowing cold air in a Wisconsin winter needs same-day attention.
Repair or replace my furnace?
If your furnace is under 15 years old and the repair is straightforward, repair is usually the right call. If it's 15–20+ years old, needs a major component, or has needed multiple repairs recently, replacement may make more sense. We'll walk you through the numbers honestly.
How long does furnace repair take?
Most repairs are completed in one visit. Simple fixes like an ignitor or thermostat take 1–2 hours. More complex repairs may require ordering a part, which typically adds 1–2 days.
Do you repair older furnaces?
Yes, we work on older systems regularly. If parts are still available, we can repair it. If the unit is at the end of its serviceable life, we'll tell you that too.
Is furnace repair covered by my home warranty?
Possibly — it depends on your policy. We can provide documentation of the repair for your records. Call your warranty company first to understand what they cover before scheduling.
