Furnace Repair in Oconomowoc, WI.
No heat at 11 PM in February is not the time to call around for quotes. Call us. We will tell you when we can be there, what we charge to show up, and what the fix looks like once we are in front of your furnace.
What We Fix
Every type of furnace, every common failure.
We service gas, electric, and propane furnaces from every major manufacturer. Carrier, Bryant, Lennox, Trane, Tempstar, Goodman, Rheem, York, Amana, American Standard, Heil. If the manufacturer is still in business, we have probably worked on it this winter.
Most no-heat calls in Oconomowoc trace back to one of a handful of parts. Igniters, flame sensors, pressure switches, inducer motors, gas valves, control boards, and limit switches. We carry the common ones on the truck so a single visit usually does it.
If it is something less common, like a cracked heat exchanger or a failed blower assembly, we will pull the part numbers, get you a real quote, and tell you whether repair or replacement is the smarter call.
What You Get
A straight answer and a fixed price.
Before any work happens, you get a written price for the repair. Not a "we will figure it out" estimate. A number you can say yes or no to.
If we open the furnace and find a second problem, we stop and tell you before we touch anything else. No surprise charges on the invoice. No upsells designed to make a $200 repair turn into a $4,000 quote for a new system.
When the work is done, we test the furnace through a full heat cycle, check the temperature rise across the heat exchanger, and confirm the safeties are doing what they should. Then we clean up.
Common Symptoms
If your furnace is doing any of this, call.
01
No heat at all
Thermostat is calling for heat, blower runs, no warm air. Usually an ignition problem (igniter, flame sensor, gas valve) or a tripped safety switch.
02
Furnace cycles on and off
Burners light, then shut off after a minute or two, then try again. Often a dirty flame sensor, a clogged condensate line, or a limit switch problem.
03
Loud bang, screech, or rumble
Banging on startup can mean a delayed gas ignition, which is dangerous. Screeching usually points to a blower motor or inducer bearing. Rumbling can be a dirty burner.
04
Blower runs nonstop
If your fan never shuts off, the limit switch may be stuck, the control board may have failed, or the fan setting on the thermostat is wrong. We can sort it out in one visit.
05
Yellow or orange flame
A healthy gas flame is mostly blue. Yellow flames mean incomplete combustion, which produces carbon monoxide. This one is not a wait-and-see. Call.
06
Higher gas bill, same usage
If your bill jumped and the weather did not, your furnace is working harder than it should. Could be a dirty filter, a failing inducer, or a burner that needs cleaning.
How It Works
From your call to a working furnace.
Call (414) 507-1789
You talk to Amanda or one of our experienced technicians. We ask a few questions (age of furnace, what it is doing, what error code is showing if any), then we give you a real arrival window.
We diagnose, you see the price
Our diagnostic fee covers the trip out and a full inspection. Once we know what is wrong, we write up a fixed price for the repair. You decide before any wrenches come out.
We fix it, usually that visit
Common parts ride in the truck. For anything we have to order, we tell you the timeline and, if it is cold out, we set up a temporary heating plan so your pipes stay safe.
We test and clean up
Full heat cycle test. Combustion check. Temperature rise across the heat exchanger. Safety switch verification. Then we sweep up and haul the old parts out.
Pricing
What a furnace repair actually costs around here.
HVAC companies love to be cagey about price. We do not. Here is what residential furnace repairs typically run in the Oconomowoc area. These are real ranges based on real jobs, not internet averages.
Your actual cost depends on the part, your furnace, and what else we find when we get into it. The number you see on the invoice will match the number you approved before we started.
Typical Repair Ranges
After-hours emergency calls are billed at a higher rate. We tell you the number on the phone, before we leave the shop. No mystery line items at the end.
Local Service
We live where you live.
We are based on County Road C in Oconomowoc. Most of our calls are within thirty minutes of the shop. That matters in January when the polar vortex drops the dew point to negative twenty and every other HVAC company has a four-day waitlist.
We cover Oconomowoc, Lake Geneva, Fort Atkinson, Hartland, Delafield, Pewaukee, Waukesha, Sussex, Brookfield, West Bend, Mukwonago, and the rest of the Lake Country area. Milwaukee too, depending on the day.
Why It Matters
Cold weather here is not a metaphor.
Wisconsin winters get serious. The 2024-25 season hit minus eighteen in Oconomowoc. At those temperatures, a dead furnace is not a comfort issue. Your pipes can freeze and burst in a matter of hours.
That is why we do not pad estimates to keep ourselves busy. When you call with no heat, we treat it like the emergency it is, get you on the schedule fast, and tell you on the phone if we can or cannot make it the same day.
Common Questions
Furnace repair, answered straight.
How much does furnace repair cost in Wisconsin?
Most residential furnace repairs in the Oconomowoc area run between $150 and $650 depending on the part. Igniters and flame sensors sit on the lower end. Inducer motors, gas valves, and control boards sit on the higher end. We give a fixed price before we start any work.
Is it worth repairing a 15-year-old furnace?
Sometimes. If the repair is under a third of replacement cost and the heat exchanger is in good shape, repair makes sense. If the heat exchanger is cracked, or you have been calling for repairs every winter, replacement usually wins out long-term. We tell you the honest answer for your situation.
Do you work on all brands of furnaces?
Yes. Carrier, Bryant, Lennox, Trane, Goodman, Rheem, Tempstar, York, Amana, American Standard, Heil, Armstrong. We carry common parts on the truck so most repairs get done in one visit.
How fast can you get out for a no-heat call?
Same day for most no-heat calls in the Oconomowoc area during heating season. Call (414) 507-1789 and we will give you a real arrival window, not a four-hour guess.
What is the most common reason a furnace stops working?
A dirty flame sensor. The flame sensor is a little metal rod that confirms the burners actually lit. When it gets a film of carbon on it, the furnace shuts itself off as a safety. Cleaning or replacing it is usually a quick fix. After that, igniters, pressure switches, and inducer motors are the most common failures we see.
Should I shut my furnace off if it is making a weird noise?
If you smell gas, yes. Shut it off at the switch, leave the house, and call us. If it is just a new noise and there is no gas smell, turn the thermostat down to stop calling for heat and give us a ring. A grinding or screeching blower can damage other parts if you keep running it.
Do you offer financing?
Yes, we offer financing on replacements. If your furnace is past the point of repair and you are looking at a new system, ask about financing options when you call.
