Arrived onsite to perform CO test. Used Carbon Monoxide Detector around apartment including kitchen area, Bathroom, and boiler room. Asked customer to turn up heat to fire up the boiler. The meter did not detect any CO. Also had homeowner run hot water to fire up the water heater. The meter did not detect any CO. The meter read 1ppm near the gas stove. This is within the allowable concentration. The customer explained he is having an issue with Carbon Dioxide spites in the morning using after or during a shower. He had a plumber clear out the main drain but that didn’t stop the spikes of carbon dioxide up to 6000 ppm. The customer believes the carbon dioxide is affecting his health. I suggest he speak to the town health department. Note the heating system is making a noise and may need a repair or replacement in the near future.
