Every time your thermostat calls for heat, the furnace runs a fixed checklist. The inducer motor starts and proves draft by closing a pressure switch, the hot surface igniter heats up, the gas valve opens, the burners light, and the flame sensor confirms there is fire. Only after all of that does the blower begin sending warm air into the house. Finding the step that fails is most of the job. Around Kennewick, WA, the usual failure points are a flame sensor fouled with oxide, an igniter cracked by years of heating and cooling, a pressure switch that stays open because of a weak inducer or a clogged condensate trap on a high-efficiency unit, and control boards with burned relays. Any one of them halts the startup, and from the hallway they all look alike.
Our experienced technicians diagnose a furnace the way it operates, in order, measuring each stage as it happens. That means igniter resistance, microamp flame signal, pressure switch operation under actual inducer draft, gas valve voltage, and blower and capacitor condition. Safety checks are never optional on a gas appliance: heat exchanger inspection, leak testing on the gas connections, and flue draft verification, since a hazard rarely shows itself at the thermostat. We finish by checking temperature rise against the data plate, making sure the burner and blower are matched the way the manufacturer designed them to.
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 no-heat calls end with heat the same visit.

How Much Does Furnace Repair Cost in Kennewick?
The typical furnace repair in Kennewick lands 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 Kennewick 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 | Furnace lights, then shuts off within seconds |
| Hot surface igniter replacementFurnace clicks and tries to start but never lights | $150–$400 | Furnace clicks and tries to start but never lights |
| Draft inducer motorStartup fan fails, furnace won't fire | $400–$1,000 | Loud humming or grinding at startup, then lockout |
| Blower motorNo airflow, or the blower runs nonstop | $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 replacementValve fails to open, so the furnace never lights | $250–$700 | Valve fails to open, so the furnace never lights |
Ranges are typical for these repairs; you get an exact quote before any work starts.
What Moves the Cost Up or Down
- 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
- Access to the furnace in attics, closets, or crawlspaces
For older furnaces facing a big repair, we'll show you what replacement would cost too, so you can compare. No heat right now? Call (541) 634-9853.
Signs You Need Furnace Repair in Kennewick
The sooner you notice these red flags, the easier and cheaper the problem is to resolve. These are the signals our technicians see most often when a problem is underway:
- Squealing or grinding from the blower compartment
- Air moving through the vents that never gets warm
- Booming or banging at light-off from delayed ignition
- A flame that burns soft and yellow rather than steady blue
- Rust streaks, soot, or water around the cabinet or flue
- The igniter glows and clicks, yet no flame ever appears
- Flames that start, last a few seconds, and go out again and again
- Frequent on-off cycling that never reaches the thermostat setting
Early Action Saves Money
Left unchecked, even a small fault or temperature swing often signals a system working its way toward a breakdown. Don't wait, get Kennewick HVAC on the phone at (541) 634-9853 and we'll take a look right away.
Your Furnace Repair Questions Answered
The Benefits of Professional Furnace Repair
Gas, open flame, high voltage, and a flue share one cabinet in a furnace, and the most dangerous failure is the one you cannot see: a damaged heat exchanger that lets combustion gases into the air the blower circulates. Every morning that delayed ignition keeps booming at startup, that exchanger takes more stress. The diagnostic side has its own pitfalls. When a furnace trips its high limit, the switch itself may be bad, or the furnace may be protecting itself from a clogged filter or a failing blower. Swapping the switch in that second case removes a safety device and leaves the actual problem in place.
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
Our systematic workflow delivers thorough, lasting results on every job. Here's how we handle furnace repair from start to finish:
Step-by-Step Diagnosis
Instead of guessing, we follow the startup sequence step by step, with readings on the inducer, pressure switch, igniter, flame sensor, and gas valve, until the broken link shows itself.
Safety Verification
The heat exchanger is inspected, gas connections are leak-tested, and flue draft verified on every visit. A furnace repair that is not proven safe is not finished.
Same-Visit Repair
We fix the confirmed fault, and since igniters, flame sensors, pressure switches, capacitors, and motors are on the truck, most furnaces are heating again the same visit.
Full Verification
We run complete cycles, measure temperature rise against the data plate, confirm clean ignition without booming, and verify every limit and safety control before we leave.

A little routine maintenance goes a long way toward avoiding a mid-season breakdown. Follow these tips from our experienced technicians:
- Notice how the furnace sounds at startup, because a quiet light-off is healthy and a boom is not
- Have the furnace checked every autumn, while a weak igniter or fouled sensor is still an easy fix
- Change the filter monthly during heating season; it is the cheapest furnace part you will ever buy
- Avoid packing the utility room, because burners need open space for combustion air
- If you have a high-efficiency furnace, check that the condensate drain is flowing freely
- Test your CO detectors monthly and make sure each floor has one
- Store laundry supplies, especially chlorine products, well away from the furnace closet
Should You DIY or Call a Pro?
Online tutorials may help in a pinch, yet lasting repairs and code-compliant installations usually depend on professional methods and trained technicians. Here's a comparison:
| Factor | DIY Attempt | Professional Service |
|---|---|---|
| Exchanger Cracks | No way to see a crack from outside | Checked every time we open the unit |
| Ignition Problems | New igniter installed on a hunch | Every stage measured before replacing parts |
| Gas Safety | Small leaks missed entirely | Connections leak-tested with instruments |
| Limit Trips | Safety switch bypassed or swapped | Filter, blower, and ducts checked for the cause |
| Airflow Match | Fan speed never checked | Temperature rise set to the data plate |
| Verification | It lit once, call it fixed | Clean, safe operation verified over full cycles |
