From the hallway, a furnace that will not heat looks the same no matter what broke. Inside the cabinet, though, the sequence is strict: inducer on, pressure switch closed, igniter glowing, gas valve open, burners lit, flame proven, and finally the blower sending heat through the house. Most of the diagnosis comes down to finding the broken link. In Cranston 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.
Cranston HVAC repairs furnaces by testing the sequence, not guessing at it. Our experienced technicians verify each stage with a meter rather than a hunch: igniter resistance, flame signal in microamps, pressure switch operation against actual inducer draft, gas valve voltage, and blower and capacitor health. Every visit includes the safety fundamentals on a fuel-burning appliance: the heat exchanger inspected, connections leak-tested, and draft confirmed, because the difference between a furnace problem and a furnace hazard is not visible from the thermostat. We measure temperature rise against the data plate before we leave so the fire and the airflow are matched the way the manufacturer intended.
Conventional or condensing, gas, propane, or electric, we work on them all, across every major brand, including the traps, drains, and dual pressure switches that come with high-efficiency models. The parts most likely to fail are stocked on every truck: igniters, flame sensors, pressure switches, capacitors, inducer assemblies, and blower motors. That is why the majority of no-heat calls end the same visit. If your furnace is down anywhere in Cranston, call (401) 204-0642 and help will be headed your way today.

How Much Does Furnace Repair Cost in Cranston?
The typical furnace repair in Cranston lands between $150 and $600. The price depends on which part failed and how old the furnace is. Cranston HVAC tests the system, finds the actual fault, and quotes the repair before any work begins.
| Repair | Typical cost | What it usually means |
|---|---|---|
| Flame sensor cleaning or replacementFurnace lights, then shuts off within seconds | $80–$250 | Furnace lights, then shuts off within seconds |
| 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 motorStartup fan fails, furnace won't fire | $400–$1,000 | Startup fan fails, furnace won't fire |
| Blower motorBurners run but little or no air comes out of the vents | $400–$1,500 | Burners run but little or no air comes out of the vents |
| Control boardErratic behavior, error codes, or no response at all | $300–$700 | Erratic behavior, error codes, or no response at all |
| Gas valve replacementIgniter glows but gas never flows to the burners | $250–$700 | Igniter glows but gas never flows to the burners |
Typical ranges for common repairs. Your exact price is quoted after diagnosis.
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
- Timing, such as a no-heat call on a cold night versus a scheduled repair
- How easy the furnace is to reach
When a repair gets expensive on an aging furnace, you'll see both options before deciding. Call (401) 204-0642 to get your price.
Warning Signs for Furnace Repair
Recognizing the warning signs early can save you time, money, and prevent significant damage to your property. These are the signals our technicians see most often when a problem is underway:
- Repeated shutdowns just seconds after the burners light
- A furnace that shuts off every few minutes before the house warms up
- Grinding or high-pitched squeals from the blower
- A fan that keeps running while the registers blow cool air
- Loud booms at startup caused by delayed ignition
- A flame that burns soft and yellow rather than steady blue
- The igniter glows and clicks, yet no flame ever appears
- Rust streaks, soot, or water around the cabinet or flue
Don't Wait for a Total Failure

Why Hire a Professional for Furnace Repair?
Gas, open flame, high voltage, and a flue all 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. Replacing the switch when the real issue is airflow removes a safety device and leaves the actual problem in place.
At Cranston HVAC, no symptom gets treated in isolation. A meter tells us the flame signal, so we never condemn a good sensor while the real culprit, a cracked igniter or a weak gas valve, stays in place. We confirm draft at both the pressure switch and the flue, measure temperature rise against the data plate to flag airflow problems early, and leak-test every gas connection with instruments, not a guess. When we are done, the furnace has proven itself safe and correct through a full cycle, and if it is nearing the end of its useful life, we tell you honestly.
How Our Furnace Repair Works
Every visit follows a step-by-step method refined over years of hands-on experience. Here's how we handle furnace repair from start to finish:
Step-by-Step Diagnosis
Instead of guessing, we follow the startup sequence one stage at a time, with readings on the inducer, pressure switch, igniter, flame sensor, and gas valve, until the broken link shows itself.
Safety Verification
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.
Expert Repair
The typical repair finishes in one trip. The common failure parts, from igniters and flame sensors to pressure switches, capacitors, and motors, are stocked on the truck and ready to go.
Final Cycle Testing
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.

Call (401) 204-0642 NowHow to Prevent Furnace Repair Problems
A little routine maintenance goes a long way toward avoiding a mid-season breakdown. Put these technician-approved steps to work around your property:
- Store laundry supplies, especially chlorine products, well away from the furnace closet
- 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
- Put in a fresh filter monthly through the heating season, the cheapest protection your furnace can get
- Listen at light-off; clean ignition is quiet, and booming means the burners need service
- Put a carbon monoxide detector on every level and test them monthly
- Schedule service each fall to catch worn igniters and dirty sensors before cold weather arrives
DIY vs. 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 | Cracks invisible from the outside | Inspected on every repair visit |
| Ignition Faults | Guesswork based on blink codes | Each ignition component tested |
| Gas Safety | Connections judged by smell | Connections leak-tested with instruments |
| High-Limit Trips | Limit replaced, cause left behind | The airflow fault behind the trip found |
| Airflow Match | Fan speed never checked | Temperature rise set to the data plate |
| Verification | Declared fixed after one flame | Full cycles proven clean and safe |
