Carbon Monoxide Testing & Mitigation

Carbon monoxide is a toxic gas that emerges in homes and buildings where combustion by-products are generated and dispersed. Appliances such as hot-water heaters, furnaces, ranges, boilers, dryers can spill this gas any facility. It is colorless, odorless and tasteless and is an asphyxiate.


At low concentrations, carbon monoxide can go undetected and contribute to nagging illnesses as well as compound pre-existing health problems and can go unnoticed in premature deaths.

Clogged chimneys occur quite often with gas and oil-fired units.  The lining of the flue deteriorates due to acidic condensation and the debris falls to bottom of the chimney flue, clogging the breeching or smoke pipe.  Do not think that all heating, cooling or utility companies that you have servicing your furnace, boiler or hot water heater always inspect your flue for this potentially fatal problem-- they do not!  In fact, Certified was called out several times right after a large utility company and HVAC company in the area had connected a hot-water heater and a furnace to a clogged flue and left the house with the units running and spilling flue gas emissions.  Please see our photo documentation of these problems.

Certified Craftsmen can help eliminate any appliance related carbon monoxide problems you may be having in your home. We can inspect your appliances venting systems and fireplace chimney annually.  Please call with any questions.
