From the hallway, a furnace that will not heat looks the same no matter what broke. Inside the cabinet, though, everything happens in a strict order: inducer on, pressure switch closed, igniter glowing, gas valve open, burners lit, flame proven, and finally the blower sending heat through the house. Diagnosis is mostly a matter of finding where that chain breaks. In Eden Prairie homes, it tends to be the same handful of culprits: a flame sensor coated in oxide, a hot surface igniter cracked by thermal cycling, a pressure switch held open by a tired inducer or a plugged condensate trap, or a control board with a burned relay.
Rather than guess, Eden Prairie HVAC tests the sequence one stage at a time. We read igniter resistance, measure flame signal in microamps, check that the pressure switch responds to real inducer draft, confirm voltage at the gas valve, and test the blower and its capacitor. Because this is a fuel-burning appliance, the safety basics come with every visit: the heat exchanger gets inspected, gas connections get leak-tested, and draft gets verified. You cannot tell a furnace problem from a furnace hazard by looking at the thermostat. Before we leave, temperature rise is measured against the data plate so airflow and flame are matched as the manufacturer intended.
We work on natural gas, propane, and electric furnaces from every major brand, both conventional 80 percent units and condensing high-efficiency models with their traps, drains, and dual pressure switches. The truck stock covers the parts that actually fail: igniters, flame sensors, pressure switches, capacitors, inducer assemblies, and blower motors, so most repairs finish in one trip.

How Much Does Furnace Repair Cost in Eden Prairie?
Most furnace repairs in Eden Prairie cost between $150 and $600. Ignition and sensor problems are usually the least expensive, while blower motors, control boards, and heat exchangers cost more. You'll get a written, upfront price from Eden Prairie HVAC after we diagnose the problem.
| Repair | Typical cost | What it usually means |
|---|---|---|
| Flame sensor cleaning or replacementBurners light but cut out almost immediately | $80–$250 | Burners light but cut out almost immediately |
| Hot surface igniter replacementFurnace clicks and tries to start but never lights | $150–$400 | No ignition; one of the most common winter failures |
| Draft inducer motorLoud humming or grinding at startup, then lockout | $400–$1,000 | Loud humming or grinding at startup, then lockout |
| Blower motorBurners run but little or no air comes out of the vents | $400–$1,500 | No airflow, or the blower runs nonstop |
| Control boardErratic behavior, error codes, or no response at all | $300–$700 | Furnace won't respond to the thermostat |
| Gas valve replacementIgniter glows but gas never flows to the burners | $250–$700 | Valve fails to open, so the furnace never lights |
Typical ranges for common repairs. Your exact price is quoted after diagnosis.
Factors That Change the Price
- The age and efficiency of the furnace, since high-efficiency models use more specialized parts
- Whether a cracked heat exchanger is found, which usually means replacement rather than repair
- Same-day or after-hours service versus a planned visit
- How easy the furnace is to reach
If your furnace is past 15 to 20 years old or the repair is a major one, we'll give you repair and replacement prices side by side. No heat right now? Call (952) 266-7968.
Signs You Need Furnace Repair in Eden Prairie
Catching these issues early helps you avoid costly problems and protect your property. Here are the most common indicators that it's time to call a professional:
- Rust streaks, soot, or water around the cabinet or flue
- A bang or boom when the burners ignite late
- Flames that start, last a few seconds, and go out again and again
- Squeals, scrapes, or grinding noises behind the blower door
- The blower runs constantly but the air never warms
- The igniter glows and clicks, yet no flame ever appears
- Frequent on-off cycling that never reaches the thermostat setting
- Yellow, wavering burner flames where they should be sharp blue
Act Before It Gets Worse
What seems like a minor issue today can take out a compressor or heat exchanger tomorrow. Call Eden Prairie HVAC at (952) 266-7968 at the first sign of trouble.

Why Professional Furnace Repair Matters
A furnace combines gas, flame, high voltage, and a flue in one cabinet, and the failure that matters most is the one you cannot see from outside: a compromised heat exchanger passing combustion gases into the air your blower pushes through the house. Delayed ignition that booms at light-off stresses that exchanger further every morning it goes unfixed. Meanwhile the diagnostic traps stack up: a furnace that trips its high limit may have a bad switch, or it may be protecting itself from a clogged filter or a dying blower, and replacing the switch in the second case just removes a safety while leaving the fault.
Our experienced technicians treat every symptom as a question about the whole system. Flame signal gets measured rather than assumed, so a healthy sensor is never replaced while a cracked igniter or weak gas valve skates by. Draft is verified at the pressure switch and the flue. Temperature rise is checked against the data plate, which is how airflow problems get caught before they shorten the exchanger's life. And the gas side is leak-tested with instruments, not a sniff and a shrug. The result is a furnace that has been proven safe and correct under a full cycle, and an honest report if the unit is nearing the point where replacement beats another repair.
What to Expect From Our Furnace Repair
We follow a proven process to ensure every repair and installation is completed to the highest standards. Here's exactly how the furnace repair process unfolds:
Step-by-Step Diagnosis
We watch the furnace's startup sequence and measure at every stage: inducer draft, pressure switch, igniter resistance, flame signal, and gas valve operation, to find exactly where it breaks.
Safety Inspection
On every visit, we inspect the heat exchanger, leak-test the gas connections, and confirm the flue is drafting. No furnace repair is complete until the unit is proven safe.
Same-Visit Repair
Igniters, flame sensors, pressure switches, capacitors, and motors ride on the truck, so most furnaces are lit and heating again before we pack up.
Complete Verification
The last step is a full-cycle test: temperature rise matched to the data plate, smooth ignition with no booming, and every limit switch and safety control confirmed working.
Maintenance Tips for Furnace Repair
Smart maintenance is almost always cheaper and easier than an early replacement. Put these technician-approved steps to work around your property:
- Test your CO detectors monthly and make sure each floor has one
- Listen at light-off; clean ignition is quiet, and booming means the burners need service
- On high-efficiency models, keep the condensate trap and drain line clear and draining
- Avoid packing the utility room, because burners need open space for combustion air
- Keep storage, lint, and especially chlorine-based products away from the furnace closet
- Schedule service each fall to catch worn igniters and dirty sensors before cold weather arrives
- Change the filter monthly during heating season; it is the cheapest furnace part you will ever buy
Comparing DIY and Professional Furnace Repair
While some minor tasks like changing filters or checking a thermostat can be handled by homeowners, most HVAC work involves refrigerant, gas combustion, and high-voltage electricity, jobs that call for professional expertise. Consider the following comparison:
| Factor | DIY Attempt | Professional Service |
|---|---|---|
| Exchanger Cracks | Damage hidden inside the cabinet | Checked every time we open the unit |
| Ignition Problems | New igniter installed on a hunch | Igniter, sensor, and valve each metered |
| Gas Connections | Small leaks missed entirely | Instrument leak test on each visit |
| High-Limit Trips | Safety switch bypassed or swapped | Filter, blower, and ducts checked for the cause |
| Blower Setup | Fan speed never checked | Temperature rise set to the data plate |
| Verification | Declared fixed after one flame | Clean, safe operation verified over full cycles |
