Local considerations

Access affects cost in Washington as much as parts do. A condenser on a tight side lot or an air handler in a cramped attic adds labour time, and that shows up in the quote before any component is priced.

Dense rowhouse stock and humid summers put cooling load on systems with very little space for ductwork. The practical result for Washington residents is that a system running at the margin in mild weather can stop entirely once sustained heat arrives, without any sudden component failure having occurred.

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

Turn the thermostat to off. A system left running against a fault can make the repair larger.
Look at the outdoor unit and confirm whether the fan is turning at all. Note what you see.
Clear at least two feet of space around the condenser so it can draw air freely.
Keep anyone heat-sensitive in the coolest part of the house with water within reach.

Questions

Washington HVAC questions

Does the diagnostic fee come off the repair?

That is the provider decision, not ours, and it varies. Ask when they confirm the appointment in Washington, because the provider states whether the diagnostic is credited against the work.

Is there a charge to call?

No. There is no charge to call and no obligation to proceed. We may be compensated by providers or partners when you call, which does not change what you pay. The provider sets their own price and confirms it on site.

What if my system is still under warranty?

Many manufacturers cover parts for five to ten years, labor rarely. Have the model and serial number ready when you call. The provider can usually tell you whether the part is covered before fitting it.

How many ZIP codes do you cover in Washington?

We publish 270 Washington ZIP code areas, each linking back to this page and to the heating page for the city. If your ZIP code is not listed, call the line and the operator checks live whether a provider covers it.

What should I do before the provider arrives?

Set the thermostat to off so the system stops cycling against the fault, clear debris from the outdoor unit, and replace a visibly loaded filter. In extreme heat, move anyone vulnerable to the coolest room in the house.
