Low or No Airflow in Cheney, WA

Cheney's housing stock tells part of this story. The area around Eastern Washington University and the Central Cheney Historic District includes homes of all ages, but the building booms of the late 2000s and early 2010s added a significant number of homes with builder-grade HVAC equipment. Those units are now 12–18 years old - right at the age when components start failing and ductwork starts showing its weaknesses.

Here are the most common root causes we find:

Clogged or collapsed air filter A severely clogged filter acts like a wall. Airflow drops, the coil freezes, and the system struggles. This is the simplest cause - and the one homeowners can check themselves (more on that below).

Frozen evaporator coil When airflow is restricted for any reason, the coil temperature drops below 32°F and ice forms on the coil surface. That ice then blocks airflow further, compounding the problem. Blower motor or capacitor failure The blower motor is what physically pushes air through your ductwork. The capacitor is the component that gives the motor its starting and running power. When the capacitor weakens, the motor struggles or stops entirely. You'll hear the system running (the compressor outside may still be on) but feel almost no air movement inside.

Duct leaks, disconnections, or collapsed sections Builder-grade flex duct - common in homes built during Cheney's growth periods - can sag, kink, or partially disconnect over time. A section of duct that's kinked 90 degrees can reduce airflow in that branch by more than half. You won't see this from inside the home, but we will.

Dirty evaporator coil Over years of operation, dust and debris coat the coil fins. A coated coil can't transfer heat efficiently, and it restricts airflow the same way a clogged filter does - just more slowly and less obviously.

Blocked or closed supply/return vents Furniture pushed against a return vent, a closed damper, or a vent that's been painted shut can starve specific zones of airflow without any mechanical failure at all.

Undersized or damaged ductwork In some cases - especially in older homes near Fish Lake Regional Park or properties that have had additions built - the duct system was never sized correctly for the square footage it serves. No amount of repair fixes a fundamentally undersized system; that requires a duct evaluation.

Before you call, run through these checks. They take five minutes and may save you time.

• Check your air filter. Pull it out and hold it up to light. If you can't see light through it, it's overdue. Replace it with the correct size and run the system for 30 minutes to see if airflow improves.
• Check every supply and return vent in the home. Make sure none are blocked by furniture, rugs, or closed dampers.
• Check your thermostat fan setting. Make sure it's set to "Auto" or "Cool," not just "Fan On." If it's set to "Fan On," the blower runs continuously - even when the system isn't cooling - which can feel like weak airflow.
• Look at your indoor unit. If you see ice forming on the refrigerant lines or on the unit itself, turn the system off and set the fan to "On" (not "Cool") to let the coil thaw. Then call us.
