Houstons Chimney Venting/Drafting Experts
Drafting issues are common with chimneys. The solutions are often quite simple. With an inspection, a Certified Chimney Technician can determine what is at the root of the problem and provide you best options for repair. It is ever so important to give venting and drafting problems your immediate attention because problems with ventilation could result carbon monoxide entering your living space and damaging your health or home.
At ASAP Operators, we can diagnose/cure your ventilation problems, and we always start with the easiest (and most inexpensive) answer, only using more extensive solutions if needed.
Before we can tell you what is the problem with a chimney’s venting or drafting, let us explain how a chimney works and what function a draft plays in an efficient and properly functioning heating appliance.
In short, when a fireplace “drafts,” it will move byproducts of combustion—including smoke or harmful gas—up your chimney and outside. Even though hot air rises naturally, other things can and will get in the way of proper drafting, resulting with soot, smoke and toxic gases in your home. This is called Backdrafting.
Ventilation And Drafting Potential Problems
Some of the drafting problems we find and correct most commonly are due to:
- A chimney flue blocked by debris
- Improper installation of chimney and/or heating appliance
- Dirty or improper chimney cap
- Incorrect Chimney Height
- Structural damage within chimney
- Broken or Damaged Damper
- Creosote build-up
- Incorrect Firebox Size
- Birds, Bats, Wasps [or others] nesting in chimney
- Additional appliance in room—such as a central vacuum, stove range vent, clothes dryer or a forced air furnace—that’s also competing for air within the house
Flow Reversal or Negative Pressure
Common problems with chimney ventilation is related to negative pressure issues. As air is removed from the home through fans or vents (i.e. kitchen fans, bathroom fans etc.), it should be replaced.
As today’s homes are built so air-tight, in many cases, the only place to bring air in is through the chimney. This explains many common complaints such as:
- Odor problems (i.e. the smell of wet ash or wet wood)
- Cold air coming from the fireplace when not in use
- Or various Respiratory issues
Although glass doors offset the flow reversal, they won’t solve the problem.
