Local considerations

Older Lynnwood housing stock often runs boilers rather than forced air, which changes the fault list to pressure, circulators and zone valves. Mention the system type when you call so the right provider is matched.

Damp cool winters suit heat pumps, which run long low-output cycles rather than short hard ones. Heat pumps in Lynnwood therefore spend more time in defrost than owners expect, and a defrost cycle that looks like a fault is usually the system working correctly.

What is your thermostat reading?

Drag the dial to the temperature your thermostat shows now. The readout names the likely cause band, how urgent it is, and which page to read next.

Degrees F

Indoor temperature

Likely cause band: Cooling capacity loss: dirty coil, low refrigerant charge from a leak, or a failing capacitor.
Urgency: Call today
Read next: AC not cooling

Thermostat reading against likely cause. JavaScript is off, so the dial is shown as a table.
Reading	Likely cause	Urgency
60 F	The heating side is not producing heat at all. Ignition lockout, a dirty flame sensor or a tripped limit switch.	Call now
62 F	The burner is lighting then dropping out, or the blower is running without heat behind it.	Call now
64 F	A heat pump that is not completing the switch into heating mode, or one stuck relying on auxiliary resistance heat.	Call now
66 F	Heat is being produced but not distributed. Airflow restriction, duct losses or a zoning fault.	Call today
68 F	Close to a normal winter setpoint. If the room feels colder than this reading, suspect the thermostat itself.	Call today
70 F	Within the normal comfort band. Nothing here points at a fault on its own.	Monitor
72 F	Within the normal comfort band. Worth noting how long the system runs to hold this figure.	Monitor
74 F	Slightly above a typical cooling setpoint. If the system cycles on and off rapidly, that is the fault to chase.	Monitor
76 F	The system is falling behind setpoint. Airflow restriction or a coil that cannot absorb heat.	Call today
78 F	Cooling capacity loss: dirty coil, low refrigerant charge from a leak, or a failing capacitor.	Call today
80 F	Supply air is close to room temperature. The refrigerant side or the compressor is not contributing.	Call today
82 F	Well above setpoint with the system running. Check for ice on the indoor coil or the line set.	Call now
84 F	Substantial capacity loss. A leak that has been developing across the season is the usual finding.	Call now
86 F	The system is effectively not cooling. Check whether the outdoor unit is running at all or tripping its breaker.	Call now
88 F	Indoor temperature is approaching outdoor temperature, which means no useful cooling is happening.	Call now
90 F	A health risk in a heat event. Move anyone vulnerable to a cooler space and treat this as urgent.	Call now

What to do while you wait

Switch the thermostat off so the system stops attempting ignition over and over.
Confirm the gas supply valve is open and that a service switch has not been knocked off.
Check the filter. A blocked one makes the furnace overheat and shut itself down.
Keep interior doors open so the warmth remaining in the house distributes evenly.

Problems we route in Lynnwood

Keep anyone vulnerable in the warmest room while you wait, and avoid improvising with cooking appliances. A gas range used for heat is a carbon monoxide risk, not a stopgap.

Questions

Lynnwood HVAC questions

What if my furnace is still under warranty?

Parts warranties of five to ten years are common, labor warranties are not. Have the model and serial number ready when you call so the provider can check coverage before fitting anything.

My furnace locks out after three tries. What is that?

Three failed ignition attempts followed by a lockout usually means the flame sensor is dirty, the igniter is weak or gas pressure is wrong. After a long idle summer, cleaning resolves it more often than replacing parts does.

Is a cracked heat exchanger repairable?

No. A cracked heat exchanger is a carbon monoxide risk rather than a comfort fault, and the correct response is replacement of the furnace. Any provider suggesting a patch on one is giving you poor advice.

Can I run a space heater meanwhile?

Portable heaters carry their own fire risk and should never be left running unattended or near fabric. Never use a gas range or an outdoor appliance to heat a room, which is a direct carbon monoxide hazard.

Do I need a carbon monoxide alarm?

If any gas appliance runs in the home, yes. Carbon monoxide is colourless and odourless, and a working alarm near sleeping areas is the only reliable warning. If one sounds, leave the building and call 911 from outside.
