Indoor Air Quality 

For more than 30 years, A-1 Guaranteed has helped local homeowners across Napa, Vallejo, and the Bay Area solve HVAC and indoor air quality problems. We install whole-home solutions that actively remove pollutants from your home and deliver results, like iWave-R and AprilAire purifiers.

Indoor Air Quality Services

iWave-R Air Purifiers

These systems are self-cleaning, require no maintenance, and are installed directly in your home’s ductwork and clean the air as it passes by. Using NeedlePoint bi-polar ionization, iWave-R systems clump pollutants together to better clean the air in your home.

AprilAire Healthy Air Systems

These systems work directly with your HVAC equipment to address several key components of air quality at once, including filtration, ventilation, and humidity control. They are all-in-one IAQ solutions that are good options for homes with multiple sources of unhealthy air.

Duct Sealing and Air Duct Repair

Leaky, damaged, or poorly connected ducts can pull dust, insulation fibers, and other pollutants from attics and crawl spaces into the air your family breathes. As a part of our insulation services, our team helps your system deliver cleaner, more consistent air to every room.

Home Electrification

Gas appliances can introduce combustion byproducts and fumes in your home. As part of our home electrification services, we help families move from gas to high-efficiency electric systems, like heat pumps, reducing these sources and supporting healthier indoor air.

Common Signs of Poor Indoor Air Quality

Problems with indoor air quality can come from leaky ductwork, small gaps between your living spaces and the outdoors, or other areas hidden from plain sight. Much of our team is BPI-certified, which means we’re specially trained to identify the source, but you may also notice:

  • Asthma and allergy symptoms that are worse inside 
  • Lingering odors and moisture from cooking, showering, and pets
  • Dust that comes back quickly after cleaning
  • Stuffy air or rooms that feel stale
  • Headaches, drowsiness, itchy eyes when inside

Why Healthy Indoor Air Matters

Indoor air quality has a bigger impact on your home than most people realize. It can influence how fresh your home feels and how well you breathe day-to-day. In the Bay Area, wildfire smoke, outdoor pollution, allergens, and everyday household contaminants can all make indoor air quality harder to manage. 

The facts below highlight just how common indoor air quality problems are, and why our team takes them seriously.

The EPA ranks air pollution among the top five environmental risks to public health.

87% of American homeowners are not aware that pollution may be worse inside their homes than outdoors.

About 40,000 dust mites, a common cause of household allergies can be found in only one ounce of dust.

Most homes generate about 40 pounds of dust per year for every 1,500 square feet of space.

Because they breathe faster than adults, children inhale 50% more air per pound of body weight than adults and are especially sensitive to air quality problems.

The World Health Organization estimates that approximately 30% of newly constructed and remodeled facilities have indoor air quality problems.

Many ordinary activities such as cooking, cleaning and redecorating can spread indoor air pollutants.

Even a spotless home can allow indoor pollutants to flourish. Bathrooms, damp basements and even carpets and furniture are often the prime causes.

According to a study by the Commonwealth of Massachusetts, indoor air contaminates are responsible for half of all illnesses.
