Carbon monoxide (CO) is an odorless, colorless and toxic gas. It’s created when you burn fossil fuels—such as natural gas, propane, kerosene—as well as when you burn wood (say, in a fireplace).
Because it is impossible to see, taste or smell the toxic fumes, CO can kill you before you are aware it is in your home. Carbon monoxide inhibits oxygen intake in the blood and can lead to death. At lower levels of exposure, CO causes mild effects that are often mistaken for the flu. These symptoms include headaches, dizziness, disorientation, nausea and fatigue. For more information see: EPA, “An Introduction to Air Quality”
At low concentrations, fatigue in healthy people and chest pain in people with heart disease. At higher concentrations, impaired vision and coordination; headaches; dizziness; confusion; nausea. Can cause flu-like symptoms that clear up after leaving home. Fatal at very high concentrations. At moderate concentrations, angina, impaired vision, and reduced brain function may result. At higher concentrations, CO exposure can be fatal.
Air sealing all or part of a home can affect how efficiently gas-burning appliances, water heaters, and furnaces work. These devices rely on a certain amount of fresh air supply to burn efficiently and to help exhaust the emissions created by burning fuel. Once a home gets sealed tightly, those fuel emissions could “backdraft” down a a flue and into the home.
Whenever we do an energy audit, we run what’s known as a “Combustion Safety Test”, using standards set by BPI as well as OSHA to make sure that your combustion appliances are running at optimum efficiency, as well as not back-drafting harmful gases into your living space. If any air sealing measures are installed, we conduct the testing again to make sure that the work had no negative impact on the equipment. Carbon monoxide is a serious concern and we want to be sure you and your family are safe.

To achieve Passivhaus certification, the homes have to achieve a minimum air tightness level of 0.60 ACH 50, which is five times “tighter” than the 3.0 ACH 50 required of new Maryland code-built houses. In this image, Robert Champ of...
Edge Energy clearly prefers installing SunPower systems. They were professional and technically informed. They were reasonable and accommodating with contractural matters. The installation crews were polite and courteous. They did neat work and were very competent. They were extremely responsive to address problems that arose. I would recommend them without reservation. They put a good face on SunPower.
Edge Energy responded quickly to my inquiries and provided clear answers. The technicians who oversaw the installation process were professional and I learned a great deal while interacting with them.
A friend recommended SunPower and Edge Energy and my expectations were exceeded. I have and will recommend both companies.
I was completely satisfied by Edge Energy. They have consistently designed and reliably installed strong performance energy innovations for my home. Indeed the only reason that I installed SunPower panels was due to their recommendation.
Edge Energy was excellent all around. Knowledgeable, friendly, willing to troubleshoot and correct issues that arose during the installation process.
