"When scheduling service for an air-to-water boiler, I was told I called "exactly the right people". The tech got here and said they almost never see these... Charged over $300 for an hour's looking around (no actual service) and drive time. So, I feel pretty seriously misled, and I still have to find someone to service the boiler. They continue to be unwilling to split the bill."

Radon Detection and Reduction questions, answered by experts

What is radon? It’s a radioactive gas that naturally occurs in the ground, forming as uranium and thorium decay. It has no color or odor, so you don’t know if it’s seeping into your building’s foundation. Regular exposure to radon gas increases your chances of suffering from lung cancer. Radon testing measures the air inside your house for the presence of radon gas. If detected, the test will measure the severity of radon levels in your home’s air.

It is possible to test for radon yourself using DIY radon test kits, but these at-home test kits should never be a replacement for professional radon testing. DIY test kits can provide some information about radon exposure in your house, but your indoor temperature and humidity can affect the results, as can improper usage of the test kit. You could save yourself some money by hiring a radon professional to begin with, and when it comes to your family’s safety, hiring an experienced professional to do the testing is usually the best option.

Mold, VOCs, radon, carbon monoxide, and particulate matter are typically measured.

Professional radon detection involves placing test kits in the lowest lived-in level of the house for a period, usually 48 hours to several months, followed by lab analysis of collected data.

Yes, most services include testing the generator to ensure functionality. Confirm with your provider.
