FAQs About Radon

Frequently Asked Questions About Radon Exposure to Radon How does radon get into the environment? Radon-222 is the radioactive decay product of radium-226, which is found at low concentrations in almost all rock and soil. Radon is generated in rock and soil, and it creeps through cracks or spaces between particles up to the outside air. Although outdoor concentrations of radon are typically low, about 0.4 picocuries per liter (pCi/l) of air, it can seep…

Energy Efficiency Ratings & Terms

Efficiency Ratings The materials from which a building is constructed, as well as the systems and appliances installed there,Â can dramatically affect the amount of energy that a building will consume over its lifetime. To help customers compare the potential impact of one to another, efficiency ratings have been devised for many building components and energy systems. A variety of energy ratings now abound, which can be confusing to the consumers these ratings were intended…

Ductless: Advantages & Disadvantages

Ductless, Mini-Split Heat Pumps Ductless, mini-split-system heat pumps (mini splits) make good retrofit add-ons to houses with “non-ducted” heating systems, such as hydronic (hot water heat), radiant panels, and space heaters (wood, kerosene, propane). They can also be a good choice for room additions, where extending or installing distribution ductwork is not feasible. Like standard air-source heat pumps, mini splits have two main components: an outdoor compressor/condenser, and an indoor air-handling unit. A conduit, which…
