A Homeowner's Guide To Air Duct Repair

What Signs Indicate Ductwork Damage?

Even though the temperature-controlled air within a home is managed by a thermostat and produced through the workings of a central air conditioning and heating unit, HVAC systems will only work with proper ductwork. This is, of course, because the air ducts are the delivery system for that temperature-controlled air. If the ducts aren't working, then nothing is. This is why keeping up with ductwork repair and maintenance is vital to keeping a home's central heating and cooling working properly. If a homeowner notices any of the signs expounded in this article, their ducts may need attention from an HVAC technician. 

Unusual Sounds Or Smells Coming from the Ducts

Air conditioners are more than just appliances that keep a house cool and comfortable. They also serve as dehumidifiers and air filters for good indoor air quality. They are supposed to produce clean, fresh air. If smells are coming up from the ventilation system, something is wrong and likely centered in the ducts. Ducts are also meant to be fairly quiet, so unusual noises are not welcome. Below are a few examples of what may be happening.

• Stale or Musty Odor: This can be due to a mold or mildew problem that has taken over the ducts. There may also be a leak in the ducts large enough to let unfiltered air into it. 
• Foul Smells: This can likewise be an indicator of mold growth, but it can also indicate a pest infestation.
• Popping Sounds: These can indicate a weakness in the ducts exposed through the temperature changes within the ducts themselves. It can also indicate that something is loose. It may also be a problem with the heat exchanger in the HVAC unit.
• Whistling Sounds: Whistling is normally created when a small amount of air escapes. This likely means a leak in the duct. 
• Scraping or Scratching Noises: Unfortunately, this almost always indicates unwanted animal guests have taken up residence in the ductwork. A homeowner may need the help of an exterminator before the HVAC techs.

Problems With the Airflow

Where did the air go? If the vents are open as they should be and the air conditioning is on, then a person should be able to perceive airflow through them. If the air is not coming through, this is likely a result of air duct issues. A few of the things that cause airflow problems include:

• Leaks in the ductwork
• Obstructions in the ducts
• Misaligned ducts

When the Utility Bill Goes Sky High

The energy bill is always a good indicator of how well a home's HVAC system functions. If the home isn't staying cool, but the utility bill keeps going up, a leak in the ducts can prevent the air from going where it needs to. This makes the efficiency of the unit bottom out, and it must work even harder to bring the home down to optimal temperature. If there is no reason for that high price, homeowners should have an HVAC inspection done.
