Each year, more than 400 Americans die from accidental carbon monoxide poisoning, with over 100,000 emergency room visits and thousands of hospitalizations tied to exposure to this odorless, colorless gas. Those numbers are a sobering reminder that carbon monoxide (CO) is a real threat inside homes, especially during the heating season.

Understanding Carbon Monoxide Risks
Carbon monoxide is a poisonous gas produced when fuel doesn’t burn completely. It can come from common household equipment like gas furnaces, boilers, water heaters, and gas fireplaces. When inhaled, it can cause serious illness or death. Because CO has no smell, color, or taste, most people don’t realize there’s a problem until symptoms begin.
Modern heating systems include safety features designed to reduce carbon monoxide risks. However, components can wear out, venting can become blocked, and equipment can fall out of proper adjustment over time. When that happens, carbon monoxide can build up inside the home without warning.
Cold Cincinnati winters increase this risk because heating systems run longer and harder. That extended use makes professional heating maintenance, proper ventilation, and reliable detection especially important during the winter months.
How Detection Systems Work
Carbon monoxide detection systems monitor the air inside your home for unsafe CO levels. When elevated levels are detected, the system sounds an alarm to alert occupants so they can get out safely and call for help. Some homes rely on battery‑powered or plug‑in detectors, while others use hardwired or interconnected systems that provide broader coverage.
No matter the type, proper placement, testing, and maintenance are essential. A detector that’s installed incorrectly or that isn’t working can’t protect your household. That’s where professional installation and testing make a difference. National Heating and Air Conditioning helps homeowners choose the right setup and ensures detectors are placed where they’ll provide the most protection.
Carbon Monoxide Detector Installation
Installing carbon monoxide detectors involves more than just mounting a device on the wall. Our team takes a professional approach to provide full coverage and dependable operation.
During installation, our technicians focus on:
- Evaluating the layout of your home and identifying fuel‑burning appliances
- Determining how many detectors are needed based on square footage and levels
- Placing detectors in recommended locations, including near bedrooms and mechanical areas
- Testing each detector to confirm proper function and alarm response
This planning helps eliminate blind spots and gives your family reliable early warning if CO levels rise.
Signs of a Carbon Monoxide Leak
Carbon monoxide exposure can affect people differently, and initial symptoms often resemble the flu or fatigue.
The most common signs of carbon monoxide poisoning include:
- Headaches, dizziness, or nausea: These symptoms may worsen the longer someone remains in the affected space.
- Fatigue or confusion: Prolonged exposure can make it difficult to think clearly or stay awake.
- Shortness of breath: CO reduces oxygen in the bloodstream, which can cause breathing discomfort.
- Pilot lights going out frequently: This can indicate combustion or ventilation problems.
- Soot buildup near appliances or vents: Visible residue may signal improper exhaust or incomplete combustion.
If multiple people or pets experience symptoms at the same time, don’t ignore the signs; treat it as an emergency situation.
24/7 Emergency CO Response
Carbon monoxide situations require immediate action. National Heating and Air Conditioning offers 24/7 emergency service to help homeowners respond quickly when a CO issue is suspected.
If you believe there may be a carbon monoxide leak in your home, take these steps right away:
- Get all people and pets outside immediately: Fresh air reduces exposure and helps prevent serious injury. If it is safe to do so and does not delay evacuation, turn off fuel-burning appliances on your way out.
- Call emergency services: Fire departments can test CO levels and confirm whether it’s safe to reenter. Do not go back into the home until authorities say it’s safe.
- Contact National Heating and Air Conditioning for emergency service: Our team is trained to diagnose combustion issues, venting problems, and equipment failures that lead to dangerous CO levels. We can identify the source and perform necessary repairs once the home is cleared.

Detectors should be installed near sleeping areas and on every level of the home. Additional units are recommended near fuel‑burning appliances and attached garages.
What Causes Carbon Monoxide Exposure?
Common causes include malfunctioning furnaces, blocked vents or flues, improperly adjusted gas appliances, and running vehicles in attached garages. Regular inspections help reduce these risks.
