Ductwork Inspection & Testing in Puget Sound

Stop Guessing What Your Ducts Are Doing

How much of the air you pay to heat actually reaches your living room? Most homeowners have no idea — and neither do contractors who quote equipment without ever testing the ducts it connects to. Eco Electric, Plumbing, Heating and Air brings professional duct inspection and testing to homes across Seattle, Everett, Mount Vernon, and the greater Puget Sound, so every decision about your comfort system starts with real numbers.

When an Inspection Pays for Itself

Before a Major Equipment Upgrade

A new high-efficiency furnace or heat pump connected to leaky, undersized ducts will never deliver its rated performance. Testing first tells you whether the existing ducts can support the new equipment — or whether sealing or resizing needs to be part of the project budget from day one.

Buying or Selling a Home

General home inspectors rarely go deep on ductwork. A dedicated duct inspection before you buy reveals crawlspace duct damage, disconnected runs, and moisture problems that turn into thousands of dollars after closing. Sellers use the same report to price and document the system honestly.

Chasing a Comfort Problem Nobody Solved

When one room never feels right and previous visits keep pointing at the thermostat or the equipment, the answer is usually buried in the duct design. Static pressure readings and register-by-register airflow measurements find restrictions and imbalances that visual checks miss.

High Bills With No Explanation

If your usage habits haven't changed but bills keep climbing, duct leakage testing quantifies exactly how much conditioned air is escaping — often 20 to 30 percent in older Puget Sound systems with decades of crawlspace moisture working on the seals.

What Our Inspection and Testing Covers

Our licensed technicians perform a full visual assessment of every accessible run, boot, plenum, and support — with photos from the crawlspace and attic. We measure static pressure at the equipment to reveal undersized or blocked runs, take airflow readings at every register, and run duct-leakage testing to put a hard number on system losses. Where runs disappear into walls and chases, camera-assisted inspection shows us the interior condition without demolition.

You get a plain-language report: what's sound, what's failing, what it costs to fix, and what it's costing you to leave alone. If the findings call for work, we price repair, sealing, or replacement options up front — you decide with the data in hand. That's been our approach since 2012, and it's why Puget Sound homeowners have given us a 4.9-star rating across more than 2,300 Google reviews.

Testing that reveals heavy interior buildup leads naturally to Duct Cleaning Services. Findings of loose joints and failing insulation are exactly what Ductwork Maintenance & Tune-Up exists to prevent. And if the air quality symptoms persist after the ducts check out, our Indoor Air Quality team can test for what's actually in your air.

The Cost of Flying Blind

Skipping testing means buying solutions to problems you haven't diagnosed — oversized equipment to overpower leaky ducts, air purifiers to mask a return pulling crawlspace air, repairs to runs that needed replacement. The inspection is the cheapest step in the entire process, and it protects every dollar you spend after it.

Get the Numbers First

Before you replace equipment, before you close on a house, before you spend another winter with a cold bedroom — get your ducts tested. Schedule your inspection or call (206) 970-1031. Same-day appointments available whenever scheduling permits, across the greater Puget Sound.
