Carbon Monoxide Safety for Fairfield Homes

When Fairfield’s cool, damp nights roll in, and your gas furnace runs more often, carbon monoxide safety becomes even more important. Carbon monoxide (CO) is an odorless, colorless gas that can be produced when a fuel-burning appliance isn’t operating properly. A cracked heat exchanger, a blocked vent, or incomplete combustion can all let it into your home without warning.

Know the warning signs:

  • Headaches, dizziness, or lightheadedness
  • Nausea or an upset stomach
  • Unusual tiredness or confusion
  • Symptoms that improve when you leave the house and return when you come back
  • Several people or pets in the home feeling unwell at once

You may also notice signs at the furnace itself, such as soot or staining around it, a yellow or flickering burner flame instead of a steady blue one, or excess moisture on nearby windows.

Protect your household:

  • Install CO detectors: Place them near sleeping areas and on every level of your home.
  • Test them monthly: Replace batteries as needed, and replace the detectors themselves according to the manufacturer’s guidelines.
  • Schedule annual furnace maintenance: A professional inspection can catch heat exchanger damage, venting problems, and combustion issues before they become dangerous.
  • Keep vents and flues clear: Make sure nothing blocks your furnace’s intake and exhaust.
  • If your CO alarm sounds: Get everyone, including pets, outside into fresh air right away, then call 911. Don’t go back inside until emergency responders say it’s safe. Once the situation is resolved, have a professional inspect your furnace before using it again.

At Environmental Heating & Air Solutions, we can inspect your gas furnace, check for safety concerns, and help you choose the right carbon monoxide detectors for your Fairfield home.
