Breathe Better: Signs You Need Air Duct Cleaning in San Jose Homes Shouldn’t Ignore

When did you last give a thought to your home’s air ducts? If you’re like most home owners in San Jose, the answer would likely be never. But ignoring this concealed system can cause substandard indoor air quality, allergies, and increased utility costs. That’s why Chimney Clean Co. now provides expert air duct cleaning in San Jose and the surrounding Bay Area — so you can breathe deeper and live healthier.

 

 

Top Signs Your Air Ducts Need Cleaning:

 

1. Ducts Emit Strange Smells

A musty or burnt smell when the HVAC kicks on can mean your air ducts are dirty or contaminated. That odor spreads through the entire house.

2. Mold and Mildew on Vents and Ducts

Seeing mold around your vents or inside the ducts? That’s a serious health hazard. Mold spores can worsen allergies and respiratory problems.

3. Air Filters Clog Frequently

If your HVAC filter fills up faster than expected, your ducts might be pushing excess dust, lint, and debris back into your system.

4. Your Home Gets Dusty Fast

If you’re cleaning more often but still seeing dust everywhere, dirty ducts may be blowing it back into your rooms.

5. Reduced Airflow

Uneven airflow from room to room is a classic sign that your ducts are blocked or dirty. That means your system is working harder and wasting energy & your hard earned money.

6. Pest Sounds or Sightings

If you hear scratching or see droppings near your vents, rodents or insects may be inside the ductwork—spreading bacteria and damaging insulation. In that case inspection and cleaning is a must for preventing future costly repairs. 

7. You’ve Recently Renovated

Construction dust and debris from renovation often make their way into ductwork. After any major renovation, air duct cleaning is a must to do job.

8. They’ve Never Been Cleaned

If your air ducts have never been cleaned or serviced — or it’s been over 5 years — it’s time. The EPA recommends regular duct inspections and cleanings to maintain healthy air quality.

Smoking back

There are many fireplaces that seem to smoke back into the house no matter what is done. In our experience, the most common cause is that the fireplace simply needs to be cleaned. This is especially likely if the fireplace has gotten worse over time, that is, the smoking back is worse now than it used to be.

Several other possible causes of smoking back are problems with the damper, chimney cap, grate, firewood, or structural problems with the chimney itself. At Chimney Clean Company, we do a full inspection with every cleaning, or we can also do just the inspection if the chimney doesn’t need to be cleaned. This inspection is designed to reveal any causes of smoking back.

Broken chimneys

In the Bay Area, many chimneys were broken in the 1989 Loma Prieta earthquake. Usually, these chimneys are broken at or near the roof line, although sometimes they can be broken further down, even at the ground level.

We are fully licensed masonry contractors. We rebuild broken chimneys. If they are broken at the roof line, this usually entails taking the chimney part of the way down brick by brick, installing steel reinforcing bars, getting an inspection from a city inspector, then rebuilding the chimney back up around the steel rebar.

Missing mortar or damaged bricks

Over time, many chimneys develop places that are missing mortar between bricks, or damaged bricks, either inside the firebox or on the outside of the chimney. These areas can usually be repaired, either by replacing the missing mortar or replacing the bricks themselves. Items such as these can be dangerous because they can allow flames, sparks or hot gases to enter the structure of the house.

Water entry

Sometimes the metal that seals the chimney at the roof, called “flashing”, will come loose or develop leaks. In this case, water sometimes comes into the ceiling of the room and causes water spots and stains on the sheet rock. This flashing should be repaired before the water causes more damage.
