Common HVAC Problems Caused by Duct Issues

In an HVAC system, the ducts are responsible for delivering and removing air. To demonstrate, stagnant, stale air leaves a home or office through ducts, and fresh, temperature-controlled air comes in through ducts. When there’s a problem with the ductwork, it can spell trouble for the entire HVAC system and for the building. At The Severn Group, our technicians come across a lot of these problems. Here are the most common duct issues and how they can affect your HVAC system.

Types of Duct Issues

duct issues featureHVAC ducts are made from sheet metal. They’re designed to last a long time, but problems can arise from improper installation or aging. Some of the duct issues that can occur include:

  • Ducts that are corroded and dirty
  • Cracks and gaps where air can escape
  • Loose, dented or collapsed ducts
  • Inefficient layout
  • Clogged ducts
  • Unsealed or poorly sealed ducts

Some of these issues can actually create problems for the HVAC system right away. However, others may gradually worsen over time if not addressed and develop into system-wide complications.

When Duct Issues Affect the HVAC System as a Whole

The following HVAC problems may result from duct issues:

• Inefficiencies

Duct issues can make it difficult for the HVAC system to regulate air. In order to properly cool or heat the building, the system has to work harder. This can create a noticeable spike in your monthly energy bills. While inefficiencies can occur as a result of many things, duct issues are one of the main culprits.

• Poor Temperature Control

Oftentimes, duct issues can affect the HVAC system’s ability to control air temperature. The building may not be as cool as you’d like it to be in the summer, or as warm in the winter. There can even be temperature variances from room-to-room, called hot and cold spots. Maybe one place in the building always feels cold, while another always feels hot and stuffy.

• Loud Noises

When everything is working correctly, the HVAC system can do its job without disturbing anyone in the building. It may make noise, but usually, it’s barely noticeable. With duct issues, however, the HVAC can become very loud. You may hear whistling sounds or popping sounds.

• Low Air Quality

One of the primary benefits of having an HVAC system is better air quality. But, when there’s a problem with the ducts, contaminants may linger in the air. The ducts are supposed to remove pollutants, such as pet dander, dust and pollen. When they fail to do so, strange odors might develop and people may start to experience negative health effects.

• Filters are Always Clogged

Does it seem like your HVAC filters are always clogged? If you constantly have to clean or replace them, there could be more to the story. Damaged ducts have been known to clog filters with particles and other debris at a faster rate.

If there’s an issue with your ducts, don’t worry. They can be repaired or replaced to get the HVAC system working as it should again. To schedule repairs, installations or maintenance, contact the HVAC professionals at The Severn Group today.
