Air Quality


In several studies, the EPA documented that indoor air quality (IAQ) in Woodbridge, VA, can be up to 70 times more contaminated than outdoor air. Many people don’t realize the impact of indoor air quality and HVAC systems on their health. Lack of HVAC maintenance is the top cause of poor air quality in homes. Some signs of bad indoor air are headaches, fatigue, skin, eye, nose rashes, lung and throat irritation.

The Aprilaire 800 Steam Humidifier is the best machine that you can have in your house for raising humidity. Some benefits are moisturizing dry skin and nasal passages and soothing allergies, colds, and flu symptoms. It also protects furniture and floors, prevents static shock, and makes you feel warmer at a lower temperature.

The installed price of the Aprilaire 800 is $2,395. They require a dedicated electrical line and circuit, which can incur an additional cost.

Power Humidifiers

The Aprilaire 700M Power Humidifier is a standard whole-home humidifier. It has the same benefits as the Aprilaire 800 at a more affordable price. However, the 700M can not put out the humidity that the 800 can and requires more intense maintenance. The power humidifiers have a greater chance of leaking and mold build-up issues if improperly maintained.

Our installation cost on the Aprilaire 700M is $1,195.


Dehumidifiers remove the humidity from the home. This helps in the summertime if you have a muggy house or areas with high humidity. It can also make the house more comfortable and run the central AC less.

The total installation cost of an Aprilaire De-Humidifier ranges between $2,995 and $3,995.

Ventilation is vital in our Heating, Ventilation, and Air Conditioning (HVAC) systems. Adequately sized and sealed ductwork can increase comfort and decrease the utility cost of your home. Properly installing the ductwork when a new HVAC system is being installed in your home is also essential. It can affect how noisy the system is. The benefits of having proper ventilation go hand in hand with the indoor air quality in our homes.

Noisy Vents & Ducts:

 We often hear whistling, knocking, creaking, or bangs from our home’s vents. These are all issues related to the ventilation system. Sealing small holes can help the whistling disappear. Knocking or tapping sounds come from our ducts expanding in the wintertime while running the heat. It can worsen if the ductwork is tight to a wall or a joist with no room to move. Creaking and rattling noises are caused by improper duct installation, ductwork that is coming loose, or debris inside. These can be as easy as tightening a few screws or as complex as replacing the ventilation system. Loud bangs from your vents when the system cuts on and off or shortly before and after. This is usually a sign that the ductwork is undersized for the size of the HVAC system in your home. When too much air is being sucked through the return ducts, it can cause the ducts to bow inward, making a banging noise. When the system turns back off, the airflow stops, and it promptly bends back outward. This usually happens on the return side of the system.

Appropriately Sized Duct Work:

 At Walker Heating & Air Conditioning, we understand that having proper ventilation is the key to the HVAC system. An appropriately sized duct system for your home is the most critical part of any heating and air conditioning installation. Suppose the temperature in your house is uneven. You may have oversized ductwork that causes uneven air distribution in your home. The best thing to do is get an ACCA-approved load calculation when replacing your next HVAC system. This ensures that you have the correct size HVAC system for the ventilation in your home.
There are occasions when the entire ventilation system needs to be redone. We can use the existing ductwork if the home’s central heating and AC system are the correct size. Modifications to the current duct work are required if the HVAC system is improperly sized before the replacement.

Unmaintained Duct Work and Ventilation:

 A family can generate a lot of pollutants like dust, dander, smoke, and pollen. Add moisture from the air, and you have a perfect living area for mold, fungi, and bacteria. This causes allergies, asthma, and other respiratory conditions. Dirty, unmaintained duct work and ventilation circulate these pollutants throughout the house. Walker’s IAQ technicians have the experience to solve all indoor air quality issues so you and your family can enjoy clean air.
With all that said, having cleaner air in your home can extend years of your life. Contact the indoor air quality experts in Woodbridge, VA. Schedule Service Today!
