Common Ways Your Air Ducts Can Get Damaged

One of the most important — and underappreciated — components of your HVAC system is your AC ductwork. Without properly sized, designed and operating air ducts, you might as well not have air conditioning at all. The amount of energy waste that occurs when you have damaged ducts is significant, and it can be especially difficult to identify, too. 

Big Mountain Heating & Air Conditioning not only offers the most effective air duct services in the area, but we also want our customers to have as much information as possible. Keep reading to find out the most common reasons your air ducts experience damage and affect your home’s heating and cooling.

Improper Cleaning

If you have recently received a Sacramento air duct cleaning, you may be facing the consequences of a contractor’s mistake. To be able to handle the volume of air that rushes into your home every day, air ducts have to be flexible. However, this makes them vulnerable to damage by the very people who are trying to clean them. During a duct cleaning, a particularly strong hand can also cause fiberglass to be exposed and enter the air. This can cause problems in the HVAC filtration system as well as irritate your respiratory system.

Inexperienced cleaning can also lead to blocked ducts. If fiberglass is lifted from its position, it could block the airflow from your vents. Not only will this cause airflow problems in your home, but it could lead to strange noises and further damage to the system.


The passage of time can also lead to weakness in the air ducts that run through your home. When the ducts weaken, they can collapse altogether. This would cause major problems, including low airflow, low efficiency and high amounts of air leakage from the restricted sections of ductwork. 

Time can cause the duct insulation to move or deteriorate as well. The point of insulation is to help control the temperature of the air as it travels to its destination. Without proper insulation, efficiency drops rapidly. 


Whether you like it or not, your house is likely home to some uninvited critters, too. As mentioned previously, air ducts are flexible. This means the errant rodent or insect that decides to munch on your air ducts can create holes or weaken the material making up the duct. If you notice strange holes or signs that your ducts are being eaten away, you can bet you’ll need air duct repairs sooner rather than later. 

Accidental Damage

Other damage to your attic or home — like severe storms, materials falling over or water leaks — can affect your air ducts easily. If you are able to identify the culprit for your damaged or smashed air ducts, professionals will be able to help you more easily. Isolated incidents can be resolved by replacing a small section of ductwork and making sure it is sealed with the existing system.

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.
