5 Signs Your Air Ducts Need to be Cleaned

July 15, 2021 | Blog

The level of comfort in your home is greatly affected by your indoor air quality. Indoor air quality is so important to be aware of because it can affect many things that go on inside your home. Short-term exposure to bad indoor air quality can present itself in many ways. Long-term air quality can potentially be dangerous. One great way to practice good indoor air quality is by making sure your air ducts are always cleaned and well kept. Here are some signs that your air ducts should be cleaned or repaired.

Dirty Air Filter

A visible dirty air filter is one of the first indicators of bad indoor air quality. If your air filter is so clogged up that it’s stopping the cold air from coming through, that’s a problem. It is recommended that your air filter be changed out at least once every six months, but it is smart to change them more regularly, especially after the busier winter and summer seasons. Simply fix this problem by replacing your air filter.

Clogged Vents

Another sign of your air ducts needing to be cleaned is the sight of clogged vents with dust and debris. If you continually see dust and different kinds of debris on the different surfaces of your home, chances are high that you have dust and debris coming from your air ducts. The longer you wait to clean the dust out of your ducts, the more it will accumulate and the bigger the problem will get. You can get this fixed by calling a professional HVAC cleaning service.

Unwanted Duct Odor

If you begin to smell an unpleasant smell coming from your ducts, that could be a major problem. If you have looked all-around your house and still cannot identify the odor, it could be emanating from your air duct system. It is recommended that you have a professional technician do a thorough inspection of the air ducts to find the source of the smell.

Mold and Mildew

One of the nastiest and most unpleasant signs that your air ducts need to be cleaned is the discovery of mold and/or mildew accumulating in your home. If there is not enough air circulation, possibly due to a dirty air filter, the dust and debris coming from your home could potentially gather to form mold and mildew. The best action to take in this situation is to call a professional HVAC technician to clean out your air ducts and make sure it is all taken care of. It is also advised that you invest in some sort of home dehumidifier since mold and mildew grow the most in wet areas.

Signs of Pests

If you’re seeing visible signs of pests in any area of your home, there is a pretty good chance that your air ducts may have been compromised by them. The smaller pests that infiltrate your home are always hiding, creeping, and crawling through the smaller hard-to-see passageways so they’re not discovered. Your air ducts are perfect passageways for these pests to go about their way. If pests are using your air ducts in any way, the chances are high that they are leaving behind waste and other dirt and debris. The best thing to do is call a pest control service to remove them, followed by professional HVAC technicians to properly clean your air ducts.

What Our Customers Have To Say

Good Rebates

This is a review for a complete HVAC system replacement from Big Mountain. I started at the SMUD website looking for the best rebate program and found a list of contractors there. I vetted out companies that had a lower number of completed jobs per the SMUD rebate program data.

Very Professional

Had my A/C go out yesterday, called Big Mountain today and they had a serviceman in my area of Lincoln, he was here within a half hour and fix my unit in a very professional manner, and the cost was reasonable. I was very impressed with the company and the serviceman.

I had a appointment with them between 1-3 and one of their staff members called me and kept me updated when they will arrive which was nice. Steve arrived on time and was really nice for explaining what could the cause be. My ac fan was working but cool air wasn’t coming out.
