Indoor Air Quality

Indoor Air Quality Services in Woodbridge

Providing Clean and Comfortable Air in Your Home or Business

In several studies, the EPA documented that indoor air quality (IAQ) can be up to 70 times more contaminated than the outdoor air. Many people don’t realize the impact indoor air quality and HVAC systems have on their health. Inadequate HVAC maintenance is a major cause of poor indoor air quality, which can cause headaches, fatigue, skin rashes, and eye, nose, lung, and throat irritation. At Walker Heating & Air Conditioning, we are committed to providing our customers with a healthy, energy-efficient, and comfortable indoor environment.

A family can generate a surprising amount of pollutants like dust, dander, smoke, and pollen. Add in moisture from the air, and you have the perfect breeding ground for mold, fungi, and bacteria, which can cause coughing, sneezing, sore throats, and watery eyes, and exacerbate asthma and other respiratory conditions. Dirty, unmaintained duct work and ventilation can continue to pump these pollutants throughout the house, making you and your family sick. For this reason, we also offer ductless mini split systems. Walker Heating & Air Conditioning’s indoor air quality technicians are trained and certified to address all your indoor air quality problems so you and your family can enjoy clean air.

Our IAQ specialists are here to help create an action plan to make your indoor air safe and clean. Depending on your needs and concerns, we can analyze your home for air filtration problem spots and recommend and install indoor air quality equipment. From ultraviolet (UV) air treatment systems to home air cleaners, our HVAC technicians will answer all your questions, provide expert recommendations, and perform quality services.

Ventilation plays a vital role in our heating, ventilation, and air conditioning (HVAC) systems. Duct work that is properly sized and sealed can increase the comfort, and decrease the utility cost, of your home. Having the duct work installed properly when a new HVAC system is installed in your home is also a very important factor and 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 and Ducts

It is not uncommon to hear whistling, knocking, creaking, or bangs coming from your home’s vents. These are all issues related to the ducting and ventilation system. Sometimes, small holes need to be found and sealed — this can help the whistling disappear. Knocking or tapping sounds can be created from our ducts expanding in the wintertime while running the heat. If the duct work is pressed tight to a wall or a joist with no room to expand, it can make it even worse. Creaking and rattling noises are usually improperly installed ducting, debris inside of the ducting, or duct work that is coming loose. Fixing these issues can be as simple as tightening a few screws or connections, or as complex as replacing the entire ventilation system. If you hear a loud bang or thump coming from your vents when the system cuts on and off, or shortly before or after, this is usually a sign that the duct work 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 air flow stops, and it promptly bows back outward. This usually happens on the return side of the system. Consider ductless mini splits to help prevent these problems.

Properly Sized Duct Work

At Walker Heating & Air Conditioning, we understand that having proper ventilation is the key to the HVAC system. Having a system that is properly sized for your home is the most important part of any heating and air conditioning installation. If the temperature in your house is uneven, you may have a system that is over-sized or duct work that is not properly sized or fitted for your home. The best thing you can do is get a cooling and heating load calculation by an ACCA-approved system such as Manual J, performed when you replace your HVAC system. This can ensure that you have a properly sized HVAC system for the ventilation in your home, with the least amount of ducting modifications. There are occasions when the entire ventilation system needs to be re-done. However, we have found that we can usually make the existing ducting work, so long as the central heating and air conditioning system is properly sized for the home. This usually requires modifications to the existing duct work if the HVAC system prior to the replacement is improperly sized.
