No-heat repair
Heating Repair — Furnace, Heat Pump & Radiant Service Warwick RI
Same-day during business hours. We carry common ignition, blower-motor and control-board parts on the truck so a Warwick no-heat call doesn't turn into a multi-day wait. Heat pumps and radiant systems too.
Symptom diagnosis
Eight common heating symptoms — what's likely, what's next
Use this to triage before calling. The likely-cause column tells us where to start; the action column tells you whether it's urgent.
Symptom
No heat at all — furnace won't fire
Likely cause
Ignition / flame sensor / thermostat
+
Symptom
No heat at all — furnace won't fire
Likely cause
Ignition / flame sensor / thermostat
Likely cause
Ignition / flame sensor / thermostat
What we do
Reset thermostat, check filter. If silent: pilot/ignitor or gas valve. Common ignition parts and flame sensors are stocked on the truck for same-day swap.
Symptom
Heat runs but blows cold air
Likely cause
Blower-vs-burner timing, dirty flame sensor
+
Symptom
Heat runs but blows cold air
Likely cause
Blower-vs-burner timing, dirty flame sensor
Likely cause
Blower-vs-burner timing, dirty flame sensor
What we do
Sensor cleaning + cycle test. 30-minute job. If recurring, control board.
Symptom
Loud bang at startup
Likely cause
Delayed ignition — gas accumulating before ignite

What we do
Don't ignore. Burner inspection + cleaning. Cracked heat exchanger possibility.
Symptom
Burning smell first run of season
Likely cause
Dust on heat exchanger — usually OK after 30 min

Symptom
Burning smell first run of season
Likely cause
Dust on heat exchanger — usually OK after 30 min
Likely cause
Dust on heat exchanger — usually OK after 30 min
What we do
If it persists past first cycle, shut down and call. Could be wiring or motor.
Symptom
Some rooms cold, others fine
Likely cause
Zone valve, damper, or trapped air
+
Symptom
Some rooms cold, others fine
Likely cause
Zone valve, damper, or trapped air
Likely cause
Zone valve, damper, or trapped air
What we do
Air-purge hydronic zones. Test zone valves under load. Could also be ductwork imbalance.
Symptom
System short-cycles (on/off rapidly)
Likely cause
Oversized unit, dirty filter, or limit switch
+
Symptom
System short-cycles (on/off rapidly)
Likely cause
Oversized unit, dirty filter, or limit switch
Likely cause
Oversized unit, dirty filter, or limit switch
What we do
Check filter first. If clean: limit switch testing, possible Manual J load review for replacement sizing.
Symptom
Heat pump runs but doesn't warm at low temps
Likely cause
Refrigerant low, reversing valve, or auxiliary heat fault
+
Symptom
Heat pump runs but doesn't warm at low temps
Likely cause
Refrigerant low, reversing valve, or auxiliary heat fault
Likely cause
Refrigerant low, reversing valve, or auxiliary heat fault
What we do
Refrigerant pressure test, reversing valve cycle, aux strip operation.
Symptom
Boiler pressure drops over a week
Likely cause
Slow leak — expansion tank, relief valve, or zone bleeder
+
Symptom
Boiler pressure drops over a week
Likely cause
Slow leak — expansion tank, relief valve, or zone bleeder
Likely cause
Slow leak — expansion tank, relief valve, or zone bleeder
What we do
Pressure-test the loop, check expansion tank charge. Often a simple fix; sometimes a hidden leak in baseboard.
Repair vs replace
Failure modes by system age — and what to do
| Age | Common failures | Verdict | Notes |
|---|---|---|---|
| 0–8 yr (forced air) | Ignitors, flame sensors, capacitors | Always | Modern furnaces are reliable; almost any fault is a low-cost part swap. |
| 9–15 yr (forced air) | Blower motor bearings, control board, gas valve | Usually | Moderate repair scope is typical. Budget for replacement in 5-7 years. |
| 16–20 yr (forced air) | Heat exchanger cracks, multi-component failure | Math-dependent | Significant repair on a 78–82% AFUE unit usually pays back as a high-efficiency replacement under 6 winters. |
| 20+ yr | Heat exchanger fatigue, unavailable parts | Replace | Major repair on a 22-year-old furnace usually only defers replacement by 12-18 months. Bad bet. |
| Heat pump 0–10 yr | Refrigerant top-up, capacitor, contactor | Always | Annual tune-up catches 80% of these before failure. |
| Heat pump 10–15 yr | Compressor, reversing valve, coil leaks | Math-dependent | Compressor swap on a 12-year-old unit is often a wash with replacement. |
Heating repair FAQ — Warwick
Can you fix my furnace today if it goes out in winter in Warwick?+
Same-day during business hours is the standard. We carry common ignition, blower-motor and control-board parts on the truck so a Warwick no-heat call doesn't turn into a multi-day wait for parts. Cold air pulling off Greenwich Bay drops effective temperature below what the thermometer reads — don't wait.
Do you service heat pumps in Warwick?+
Yes — mini-split and ducted systems from all major brands. A heat pump that isn't tuned and clean drops 15-25% of its real-world output. Coil cleaning, refrigerant verification and reversing-valve checks are what keep a Warwick heat pump actually delivering at 25°F.
Do you work on radiant floor heat in Warwick custom builds?+
Yes — common in Cowesett and waterfront builds along the bay. When a zone fails in a stone or tile floor it isn't a fixture you can swap. We diagnose with thermal imaging and pressure testing, isolate the failed loop, and repair through the manifold whenever possible — opening the floor is the last resort.
