Causes of Low Air Flow in Your Furnace
Furnaces are “forced-air” systems: they distribute the heat created in the furnace’s cabinet through ductwork using an air handler. Your furnace’s burners, gas jets, heating elements, and heat exchangers can work perfectly—but without proper airflow, the heat they generate will not reach you. When you discover low airflow coming from your house’s vents, it points toward a possibly serious problem with the furnace.
There are a number of potential causes for a drop in furnace airflow. The list below will give you some diagnostic help discovering what may be causing the problem.
3 Possible Causes of Reduced Airflow From a Furnace
- Clogged air filter: The air filter installed in the furnace’s intake prevents debris from entering the cabinet. It needs to be changed once a month during the height of the heating season, or else the filter will become clogged with dust and dirt and begin to choke off the airflow into the furnace. (A clogged filter can cause other trouble as well, so make sure you have it changed on schedule.)
- Breaks in the ductwork: The sealed ductwork maintains the pressure of the air as it travels from the furnace to the vents. If breaks or gaps appear in the ducts, they will cause the air to escape and air pressure to drop. This will also allow an infiltration of dust into the ducts and a loss of heat. If you notice a musty odor along with the reduced airflow, then duct breaks are a probable cause. You will need professional duct repair and sealing.
- Broken air handler: The air handler of the furnace contains the blower and motors that send the air through the furnace for heat exchange and then into the ventilation system. Damaged or broken motors, bent fan blades, cracked fan belts, and electrical faults can all contribute to an air handler than can’t work at its regular level. The components will need repairs, or the whole air handler may require replacement.
Furnaces Need Professional Repairs
Changing the air filter is something you can take care of on your own, but for any other issues with airflow, you should call professionals to look into the problem and find the best way to remedy it. If changing the filter doesn’t restore your airflow, get on the phone and call Goettl for excellent heating repair.

What Our Customers Say About Us
After note. Cameron came back by a day later to check on readings he wasn't able to get on first appointment. I have high confidence in his work. I'm very likely to work with them again
Brayan and Marcos did an awesome job on the new ac installation. Installed with no issues and has been on ever since. Perfect time with summer coming up. Walked through and job was very clean and organized. Great work ethic. Great guys.
Good Customer Service is terribly undervalued. GREAT customer service is almost unheard of nowadays. That above all, when paired with truly quality work will always ensure not only a return customer, but also brand loyalty.
Update - our air conditioner went out today (10/26/23) and JEHAD showed up to repair the issue but the issue was bigger than expected. Tomorrow we will have a brand new system! Goettl is an EPIC firm that treats customers right. Thank you again JEHAD for going above and beyond.
Goettl is the epitome of what excellent customer service is! Our Drain King, DAREAN, addressed all of our questions and concerns and not only unclogged our drain but went above and beyond to show us our drains leading to the street were free and clear of any other issues. Thank you Darean and thank you Goettl for a great experience!
Update: great experience with Edgar Loredo who kept it real with us and was very transparent. I appreciate his honesty and recommendations. Will be requesting him as our technician in the future if we choose to use Goettl

We had an blockage in our sewer line.
Tyler Leija was dispatched the same day, and found the blockage using a camera tool.
He cleared the blockage temporarily.
The actual fix would require digging up and replacing the bad area of pipe.
Paulo "Adrian" Dado and his crew came out the next day with backhoe, dug up the area, and replaced the section of pipe.
The next day, after inspection, Adrian and his crew filled in the hole and then cleaned up the area.
This is a brief description. There was A LOT of work involved.
Very professional work.
Our tech Jorge that came out the day before helped quickly assess the situation and get us set up for a new system and water heater. Jorge was very friendly, would highly recommend!
Frank did an excellent job at explaining every thing in terms that were understandable to both myself and my wife. This greatly assisted in making the right decision to look at all options on either repair or update/purchase for the future and in the long term, saving money.
Will definitely call and use
Goettle again and I will ask if Darrean could help again.
Couldn’t be happier. Came all the options
