"Susannah is a GEM! We love her and will never hire anyone else to clean our house. She has great attention to detail and goes above and beyond. After she leaves, we just point out things she did such as “She cleaned my mouse pad!” or “She cleaned the toaster oven!” And praise her work. She is professional, reliable, and does such a good job. She is worth every single penny and more. We are so lucky to have her!!"

Air Duct Cleaning FAQs, answered by experts

Vents may blow air even though the air conditioning system is off because of the pressure difference between indoor and outdoor air or drafts from leaky ducts. Check for leaks or drafts in the ductwork or around windows and doors.

Ozone can damage building materials and belongings in your home, as the same oxidizing powers that allow it to remove odors can break down other things in your living space. However, it would take long-term exposure for any noticeable damages to occur. Since ozone smoke removal takes 24 to 36 hours, a treatment or two won’t have much of a negative impact on your belongings.

Several factors contribute to the persistent growth of mold in vents, with excess moisture being the most common culprit. Consistent mold formation in vents indicates an ongoing moisture problem within the HVAC system or its surroundings, likely caused by condensation on cool surfaces in areas with high humidity. Moisture accumulation can also result from leaks in ductwork, inadequate ventilation, or insufficient insulation, creating an environment favorable for mold growth. Regular inspections, addressing potential sources of moisture, maintaining proper ventilation, and routine HVAC maintenance can help prevent the recurrence of mold in vents. If the issue persists, seek professional assistance to identify and rectify the underlying problems.

Any unexplained smell in your house should be investigated. However, some home odors are "red flag" worrisome because they pose immediate health and safety risks. Odors should be taken seriously when accompanied by headaches, nausea, or lightheadedness. If you smell an egg-like aroma, this is probably natural gas. You should leave the home immediately, and  contact your gas company.  

You should remove and clean your HRV filters about once a month, as debris will build up quickly, especially on the fresh air side of the ductwork. Even with routine cleaning, you should plan to replace the filters at least once a year or more often if you find that they’re getting dirty quickly during operation.
