"They were able to clean some of the ducts, but explained some ducts needed completely replaced due to the mice. Replacement was not a service they did, but they did supply the name of a company to contact for replacement. They were very honest, only charged for the services they provided. I would recommend them again and will use them again myself."

"It went very well. I met with Sergio and he explained everything very well. He went into attic to inspect and found asbestos. He sent someone out to remove it. I was glad he pointed it out to me because I found it can cause cancer. He assigned someone from the office and she scheduled all the appointments including the inspection that was done today. They cleaned up every time they left my house and it looked like they were never here. They were really professional and always on time. They were just a great company overfall."

"When Mary Poppins needed a Chimney sweep she called her guy. When I needed one I called Chimney Sweep Masterâ s, Jonathan! He was fast to respond, schedule and show up for the job. To avoid being late by way of an employee that was understandably behind do to a rain storm he showed up hisself! He did an inspection, a sweep and a sprucing up of the fire place with a fresh coat of paint all in two hours!!! He even checked my drier vents as he is â full serviceâ !!!! And just like thatâ ¦. I am ready for winter!!"

Air Duct Cleaning FAQs, answered by experts

You have two different types of air vents in your home: supply and return air vents. Your supply air vents are responsible for pushing air into your home. Meanwhile, return air vents draw warmer air back into the ductwork to condition it by removing the warm molecules from it. Both types of vents are necessary to a working HVAC system and a comfortable home.

To effectively clean fine dust after construction, start by dusting high surfaces like ceiling fans, walls, and window sills, allowing the dust to settle. Then, use a vacuum with a HEPA filter on all surfaces, including furniture, carpets, and floors, making a second pass for thoroughness. Follow up by mopping hard surfaces with a damp mop to capture any lingering particles. It's also important to clean appliances, vacuum HVAC returns and supply vents, and replace the air filters. Properly ventilate the home to help clear out remaining dust, and avoid sweeping, which can spread the dust around.

Yes, vent deflectors do work to redirect hot and cold air distributed from your HVAC system. If installed correctly—and magnetic deflectors make it easy to DIY— you might find that a deflector is enough to redirect the warm or cool air where you prefer it to be. At the very least, it’s an easy, inexpensive experiment before committing to the bigger project of moving the air vent to a new location.

While you can put air fresheners at the opening to ductwork, most experts don’t recommend it. You will only disguise the odors rather than treat the underlying cause. Plus, blasting the concentrated chemical fragrance into your home’s air when the HVAC system is on may be overpowering and cause respiratory issues.

To get water out of AC vents, first identify the source of the water. Check other air vents in your home for signs of moisture. If you can’t find any, look around the room for anything that might have seeped water in like an overwatered plant or a spill. Meanwhile, if you notice more than one air vent wet in other areas of your home, it’s more than likely an issue with your insulation, roof, or air conditioner. Start by hiring an HVAC technician who can trace the source of the leak for you.
