"Dave contacted me by phone in response to my request for a quote. He told me what the cost would be, and that is what I was charged when the job was completed. The price was very reasonable. He was professional, courteous, and showed up on time. He did a great job getting out duct work cleaned out and communicated with me at the end about what he found. I'd recommend this company and will use their services again."

"Springfield location. HIGHLY RECOMMEND! Great communications, very friendly and knowledgeable staff. They cleaned the ducts, cold air registers and dryer vent and explained every step from start to finish. They even showed me before, during and after pics as they went along. 40 years and 3 dogs later, the ducts are amazingly clean. Well worth the money. Excellent staff and service!"

Air Duct Cleaning questions, answered by experts

If your AC runs constantly, it could be due to a number of things, including a faulty thermostat, incorrect temperature settings, or broken equipment. Alternatively, you might have an airflow problem (for example, blocked vents or leaky ductwork). Either way, an HVAC pro can identify the specific problem and fix it for you.

It is generally not a good idea to completely cover or close air vents. While you might have heard that closing vents in unused rooms saves energy, it does not improve HVAC performance or lower your energy bills. In fact, blocking, covering, or fully closing vents can create a buildup of pressure inside your ducts, which can lead to leaks, holes, or other problems. To maintain proper airflow, you should also avoid covering vents with furniture. If you want to reduce airflow to unoccupied parts of your home, it is better to partially shut the vents (between 50% and 75%) rather than closing them completely.

There are a few things that you can look out for that indicate that you need duct sealing, but the two most critical ones are less comfortable air in your living space and increased utility bills. If you notice that you’re paying more often for HVAC servicing and maintenance, that could suggest that you need duct sealing, as well, as leaks put added strain on your system. You may also notice musty odors in parts of your home, as leaks can lead to condensation on your air ducts that can promote mold growth behind your walls.

Finding mold in an HVAC system is never fun, but the good news is you can clean it and send those spores packing. That being said, hiring a helping hand may be necessary to fully remove the mold and prevent regrowth. Professionals use specialized tools and cleaners, such as antimicrobial solutions and HEPA vacuums, to safely remove mold from ducts, coils, and other components. For small amounts of mold, homeowners can clean visible areas using a mix of water and detergent, but they must wear protective gear and avoid spreading spores.

A dehumidifier can reduce condensation on your ductwork by lowering humidity levels in the air. Condensation occurs when humid, warm air makes contact with cold ducts. A dehumidifier can help maintain your home's indoor humidity below or around 50%, minimizing moisture buildup. However, if condensation is caused by leaks, cracks, or other damage, a dehumidifier won’t solve the problem.
