Why Indoor Air Quality (IAQ) Matters

With age-old concerns like allergens and brand new worries like COVID-19, indoor air quality (IAQ) matters for your home health more than ever. Haller’s trained and licensed technicians can help locate issues with your IAQ systems, offer innovative solutions, and bring your IAQ up to or beyond standard.

Step One

Purify Your Air

Air purification systems help decontaminate your air by removing harmful particles and pollutants.

Step Two

Improve Your Ventilation

Introducing clean air (and removing stale air) will help keep your indoor air fresh and prevent contaminant buildup.

Step Three

Circulate Your Air

Once you bring in fresh air, you’ll need to effectively move it around your entire home so it can fill each space.

How Clean is Your Air?

The U.S. Environmental Protection Agency states that indoor air quality is often worse than outdoor air quality. There are three categories of pollutants that can build up in your home: chemical contaminants, particulates (very small organic and inorganic compounds), and biological pollutants like bacteria and airborne viruses, including COVID-19.

Do you have pets in your home, suffer from allergies or asthma, or experience dry throat, skin, or eyes? If so, your home may have issues with indoor air pollution.

Here are some questions to ask yourself if you aren’t sure if your IAQ is up to par:

  • Does my home have a healthy level of humidity?
  • Does air circulate throughout fairly easily?
  • What ventilation methods am I using at home?
  • Are there chemicals and other volatile products stored inside?
  • How many people are sharing this space?

You may find there are some sources of contamination lurking around your home, but don’t fret, there’s plenty you can do about it.

Improve Your IAQ

There are steps you can take right now to make way for cleaner, healthier air. First, promote ventilation the natural way by opening windows and doors to allow fresh air in. Next, use fans or window air conditioners with the vent control open to circulate air within your home.

Be sure to run the exhaust fans in your kitchen and bathrooms to help remove local contaminants (you need to open a window to let fresh air circulate inwards, too), and stick to your cleaning routine, focusing on carpets and floors where allergens can easily gather.

Regular HVAC maintenance

System maintenance will keep you one step ahead. Maintenance doesn’t only improve efficiency and extend the life of your system, it can also help your system clean your air and keep it fresh.

Regular HVAC system maintenance can include frequent filter changes, cleaning, and professional tuneups to help your HVAC system and accessories work better for you.

Systems and Devices for Better IAQ

We carry popular devices to boost IAQ from top brands in the industry.

Air Purifier

Air Purifiers

For the latest in clean air technology, we install home air purifiers that use bipolar ionization to deactivate harmful substances circulating in your air.

Air Filter

Air Filters

Filters help rid your air of contaminants that can trigger allergies, asthma, and other symptoms. Change out old HVAC filters for new ones as often as every two months.

UV Lights

UV Lights

Direct exposure to ultraviolet (UV) light has been proven to inactivate bacteria and viruses. UV radiation lamps work to keep your air, water, and surfaces constantly disinfected.



Dealing with dry air? Consider a whole house humidifier. A humidifier benefits your home by protecting against a buildup of germs, mold, and other pollutants.

Air Handler

Air Handlers

Air handlers can help maintain the right temperature and humidity levels throughout your home by circulating even amounts of hot and cold air.

Air Booster Fan

Air Booster Fans

Mounting booster fans in your ductwork helps to move hot and cold air quickly in your home, improving air circulation (while removing odors and pollutants).

Air Flow

Ventilation Systems

Ventilation systems expel pollutants through your home’s ductwork and a network of fans. They extract and supply air to your home efficiently.

Smart Maintenance

Updated HVAC Systems

Whether your current HVAC system is older than 10 years or it’s just not working the way it used to, you might consider a replacement — this can boost IAQ and save you money.
