Duct Cleaning makes your air healthier

It’s a fact of life that dust, debris and hair builds up in your air ducts. Removing it creates healthier air flow and reduces potential allergens in your home. In addition to improving your indoor air quality, duct cleaning also ensures that less debris falls back into your heating system. This prolongs the life of your equipment. So, your heating and cooling equipment will last longer, run more efficiently and you’ll save money on your energy bills.

When should I get my ducts cleaned?

Many Seattle homeowners have duct cleaning every two years. We recommend doing it during the summer, prior to the fall heating season.

According to NADCA (National Duct Cleaning Association), frequency of cleaning depends on several factors, including the preference of the home owner. People often consider more frequent cleaning when there are:

• Smokers
• Shedding Pets
• Water Contamination or Damage to the Home or HVAC System
• Residents with Allergies or Asthma who Benefit from Fewer Indoor Air Pollutants in the Home’s HVAC System
• After Home Renovations or Remodeling
• Prior to Occupancy of a New Home

Frequently Asked Duct Cleaning Questions

How do I know if my air ducts need repairs?

The ducts that run through your house are a critical part of your forced air heating and cooling system. Ducts are often leaky, wasting up to 30% of the heating or cooling you create. You might suspect leaky ducts if you find:

  • Some rooms are too warm or too cold
  • You are maintaining the setting on your thermostat but your utility bills are climbing
  • Your cat really likes one spot on the floor and that spot feels warm (no joke!)
  • The furnace filter gets dirty very quickly, which may indicate leaks in return ducts.
  • You see visible dust at your registers
  • There is no insulation on ducts that are visible in the house

I suspect I have leaky ducts, now what?

The first step would be to perform your own visual inspection, if you see a duct that has come apart, put it back together. That is unusual, but it does happen. More likely if you see the factors noted above and suspect leaks, you can call us for a home energy audit. During the audit, we use special diagnostic tools to determine duct pressures, air flow and leakage. This is only some of what we do during a home energy audit. After the audit, we will have pinpointed the source of leaks in your home and if you decide to proceed, we can then fix them. A good duct sealing evaluation should include:

    • Finding duct leaks with diagnostic equipment.
    • Duct sealing with mastic, metal-backed tape, or sealant.
    • Airflow testing.
    • Insulating ducts that are visible but not inside the main part of your house. This is called unconditioned space for example an attic or crawlspace.
    • Testing combustion appliances (i.e. gas/oil furnace, water heater) to make sure they are venting properly after ducts are sealed.
    • Adding air returns if needed.

How does duct vacuuming affect indoor air quality?

Duct cleaning is considered part of a good overall plan to improve indoor air quality, along with heating system maintenance, filter changes and proper ventilation.

According to NADCA, a typical single family home has up to 40 pounds of dust, plus dander, molds and chemicals, created annually through everyday living. Your heating system is the lungs of your home. The system taken air in and breathes air out continuously. The contaminants are pulled into the heating system and then re-circulated back through the house 5 to 7 times per day. While many particulates are excluded by the furnace filter, over longer periods of time, this re-circulation causes a build-up of contaminants in the duct work. This can have two impacts, aggravating asthma or allergies and potentially making your furnace work harder than it should, shortening its lifespan.
