Obstructions in the air ducts are common issues homeowners can face, which can result in poor efficiency, unhealthy indoor air quality and a higher energy bill each month.
By understanding the most frequent causes of ductwork obstructions, it’s much easier to locate the problem, fix it and keep the issue from occurring in the future.
Poor Original Installation
Many ductwork problems are caused by haphazard installation by less experienced HVAC technicians. Missing pin-spotters and bad glue jobs can cause the duct liner to hang or detach completely, creating both blockage and air leaks at the same time.
Post-Construction or Renovation Debris
Other times, renovations to the home or even cable TV installation if done incorrectly can cause ductwork obstructions or damage to the duct’s liner. This can result in leaks, blockage and poor airflow. After construction is completed, miscellaneous junk can be left behind and can easily become an obstruction as well.
Other Common Ductwork Obstructions
Air filters can become lodged in the ductwork, obstructing the airflow and causing inefficiency, and dirt and grime on the blower fan can reduce its ability to push air out of the ductwork and into your living spaces. Flex duct defects, loose insulation in the ductwork and return-air grilles covered in dirt and debris are other common issues found by HVAC professionals upon evaluation.

"Ernie & Mike did a superb job on my new furnace and A/C installation. Despite having more than a day’s work to do, they came in and stayed until the job was done. They were organized, efficient, and protected the rest of the house well. Got both furnace and A/C installed the same day. Ernie was courteous, informative, and clearly knew his job better than anyone I’ve encountered before. The units look so good guests now get The Tour of our new system. Apollo is clearly not a fly-by-night company. I would recommend them to anyone in need of a new furnace and/or A/C."

"I called Apollo because of a water leak I thought I had in our upstairs shower going into the kitchen. Robbie came and assured me everything was fine & looked at all the other plumbing. He ended up changing a few pipes for our washer & clearing a drain. He was very nice & knowledgeable with all my questions. I ended up signing up for the care plan & was very happy with my service."

"The team at Apollo exceeded my expectations. As a business owner, my attention to the details and commitment to providing excellent service is high. From the sales rep. to the installation team, everyone’s performance was outstanding. For example, the installation team went to great lengths to protect our floors, placing floor runners and across the wood floors and up the stairs. They even were spot washing walls upon their departure. I highly recommend this company."

"We scheduled an estimate AND a tune-up. We knew something was wrong with our furnace, but hoped we could make it through the rest of the season. Upon telling Bill what our furnace was doing, he warned us immediately what the possible outcome was going to be; a cracked heat exchanger. He watched the flames roll backward, tested carbon monoxide levels, which were so high they meter’s last reading was 5,600 before saying “high”. He immediately shut it down, tagged it, and explained that with levels that high and children in our home he wanted off right away. He continued his inspection and showed us via a camera that not only was it cracked in multiple places, but had holes all over it. He gave us a few options for repairing it; his knowledge as well as genuine concern was beneficial and refreshing. Luckily we also scheduled an estimator, Micah, to come too and we were able to get costs between repairing and replacing (with several options). We decided to replace with a much higher efficiency furnace and one sized properly to our home. Hands down, not only did they both provide us great service and knowledge, but without sounding dramatic, they may have saved our lives. This was our first time calling Apollo, but it won’t be our last."

"Apollo is an excellent company. I always receive great service. Alex A. was professional and friendly. He kept me informed during the process of checking my furnace and heat pump to make sure they were working properly. The company makes sure you are notified who is coming and when they are on the way. All my interactions with the company have been wonderful."
