Air ducts play a vital role in circulating conditioned air throughout your home. To help improve your Missouri home’s airflow and indoor air quality (IAQ), you want your air duct system, or ductwork, at its best.

Whether you need ductwork installation, replacement, repair, or maintenance, our team at AA Mechanical Contractors is here to help. We offer complete air duct services in Windsor, MO, and nearby communities.

Do You Have Leaky Ducts?

A correctly installed and well-maintained air duct system provides healthy ventilation and air control. It also helps protect your heating, ventilation, and air conditioning (HVAC) system. Many heating and cooling issues that seem mechanical could trace back to your air ducts.

When there is an issue with your ductwork, leaky ducts are the usual suspects. The US Department of Energy (DOE) finds leaky ducts can lower your monthly energy efficiency by up to 30 percent. If you’ve noticed inconsistencies in ventilation coming from your ductwork, you may have a circulation problem caused by a leak.

Leaky ducts can also have a negative impact on indoor air quality. Leaks open up your ductwork to unwanted contaminants: dust, moisture (a favorite of mold), bacteria, pests, and more. These contaminants can trigger or exacerbate allergies and asthma.

Think your ducts may have sprung a leak? Here are some giveaways:

Poor insulation can lead to certain inconsistencies. We recommend casing your air ducts with proper insulation to ensure your ductwork stays consistent throughout your home.

AA Mechanical is the best around the Golden Valley. The huge storm that just came through the town took down our 100 year old oak tree. The tree snapped the electric service line, meter came off our home. Once energy safely shut off service to the downed lines they were able to reconnect-rebuild my side of the service lines. Their fast response and quality of service is the benchmark. Thank you Alva and your team at AA Mechanical.

These are great guys to hire! They do a good job, are nice, work hard, clean up after themselves, will do whatever it takes to make sure all is running smooth, does what they say they will do, gets back to you on the phone, shows up when they say they will, and are a pleasure to deal with and have around while they are working. An honest company that can do harder things like boilers which aren't that common.
