Indoor Air Quality

What is Indoor Air Quality?

Indoor Air Quality (IAQ) refers to the cleanliness of air that resides within homes, offices, and buildings in relation to how many pollutants occupy the same air space. There are several factors that affect indoor air quality including ventilation, humidity, temperature control, composition of the building, and external activities that bring outdoor pollutants inside. Poor indoor air can cause adverse health effects; some are immediate such as the transmission of viruses, allergic reactions, asthma or fatigue while other effects may not appear for years. The first defense against poor indoor air quality is diligent care.

UV Light Air Purification System

Installing an Ultraviolet (UV-C) Light Air Purification System, or Germicidal Light, significantly improves your indoor air quality by purifying the air circulating throughout your HVAC system. UV light air purification systems are proven to eliminate 93.6% of all viruses, bacteria and germs in just two hours! UV-C lights are placed in the air ducts of your existing heating and air unit to safely remove harmful pathogens like airborne viruses and germs before they reach you – helping you breathe clean purified air.

Air Duct Cleaning & Fogging

Air duct cleaning is the process of removing dust, allergens, and other airborne irritants that enter your home through the circulation of your warmed or cooled air. This type of indoor air pollution oftentimes goes unnoticed as it is hidden within the ductwork of your home. We recommend having your system’s ducts professionally cleaned by a licensed and certified technician every three to five years. A good rule of thumb is if your ducts look dirty then they most likely are.

Routine duct cleaning is a cornerstone of improving air quality. Beyond the dust and debris that can reside within your ducting, mold and small rodents make their home within ductwork and can negatively affect indoor air quality. Bill Howe’s air duct cleaning services will take care of all these possible pollutants.

If you are looking for a deeper sanitation solution for air ducts, ask about Air Duct Fogging. Our Air Duct Fogging service applies an antimicrobial solution that eliminates stubborn pollutants, removes odors, and is harmless to your health. According to the Environmental Protection Agency (EPA), Air Duct Fogging contains no environmentally damaging propellants, no flammable ingredients, and does not require the area to be vacated. Air Duct Fogging is a safe and effective solution to removing unwanted pollutants from your home.

Frequently Asked Questions

Q: How to improve Indoor Air Quality?

A: Eliminating all allergens within your home is not possible but there are measures you can take to reduce exposure to them. If you are looking to improve your indoor air quality, here are a few measures you can take:

  • Regular cleaning and vacuuming of hard surfaces and carpets.
  • Keep plants outdoors. Although they look nice, plants are easy hosts for mold and other air pollutants.
  • Change the filters on your HVAC and other purification equipment. Changing a filter will reduce the amount of dust and debris that is being recirculated into your home.
  • Invest in an air purifier.
  • Good air circulation in the home. Opening the windows and doors will allow stagnant, sitting air to move through the home and out, and bringing fresh air in.


Q: How to measure Indoor Air Quality?

A: Indoor air quality is measured by a combination of factors such as temperature control, humidity, ventilation, and how contaminants are controlled. Ask our certified specialist about how to better monitor indoor air quality.

What David says about us

Service for new garbage disposal. My ancient garbage disposal quit working, went online to get Bill Howe’s number, immediately received and accepted chat to describe my needs. Prompt call back to schedule an appointment, service tech Allen was out same morning, which was important to fit my work schedule. Job estimate was clear, work done fully to my expectations, area left clean, and price was very fair.
I was not surprised — I have used Bill Howe plumbers for several other tasks in the past. I have always found their staff to be helpful, attentive, and the plumbers very courteous and capable.

What Mira says about us

Bill Howe never fails us! We had a drain overflow, and Scott came (on a Saturday) to look at it and offer solution. He was punctual, professional, and extremely helpful. I should also praise the main office for always being helpful and always finding solutions. Very grateful to have you in San Diego!

What Ed Gohlich says about us

Cory was our technician on this job. We had a time sensitive repair issue and Bill Howe understood and assisted with getting the job done quickly.
Cory was on time to start the job and finished it quickly. Upon his leaving our home he’s was courteous, very knowledgeable, explaining what the problem was and how he fixed it. Very good communication and this is the way it’s has always been when we use Bill Howe plumbing.
Great company to work with.
Thanks Cory.

What Bridgett says about us

I am extremely happy with the service we received from Bill Howe Plumbing. We were given an incorrect diagnosis of our main sewer line from another vendor, but Bill Howe’s servicemen came out for a second opinion, correctly diagnosed our problem and resolved our back up issues. We will continue to use Bill Howe for all our future plumbing needs!

Thank you Bill Howe Plumbing.
