Air Duct Cleaning
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 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, prolonging the life of your equipment. In short, air duct cleaning will help your heating and cooling equipment run more efficiently and save money on your energy bills.
When should I get my ducts cleaned?
Many Northwest homeowners have duct cleaning every two years. Homeowners may want to consider more frequent cleaning if the home contains smokers, shedding pets, water contamination or damage to the home or HVAC system, residents with allergies or asthma, recent home renovation or remodeling.
How does duct vacuuming affect indoor air quality?
Duct cleaning is key to improving indoor air quality, along with heating system maintenance, filter changes, and proper ventilation.
According to NADCA, a typical single family home accumulates up to 40 pounds of dust, dander, mold, and chemicals annually through everyday living. Think of your heating system as a pair of lungs, breathing air in and out continuously. The contaminants are pulled into the heating system and recirculated back through the house 5 to 7 times per day. While many particles 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 aggravate asthma or allergies and potentially shorten your furnace’s lifespan.
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. The best course of action is to call us so that we can pinpoint 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:
- Identification of 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 (unconditioned space such as an attic or crawlspace)
- Testing of combustion appliances (gas/oil furnace, water heater) to make sure they are venting properly after ducts are sealed.
- Addition of air returns, if needed
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
