p { margin: 0; }Radon Professionals: Has there been a discussion or consensus about a "reasonable", ethical or "industry standard" radon system warranty period? When I began, one year seemed to be the standard. Now I run into 60 year old mitigators giving 25 year guarantees. In the real world it seems rare to find a warranty longer than a year. Radon fans may be the exception. When does the length of the "guarantee" just become dishonest hype? One company offers a year, then next five, then I offer ten, then you 15 and now I see some at "lifetime" whatever that means.If I missed this conversation because of living in the hinterlands I apologize but appreciate hearing thoughts on "reasonable and ethical" guarantees.Thanks, KenENVIRONMENTAL TESTINGKen Wyrick, kwyrick@q.com780 Pine Drive, Ridgway, Co. 81432-9669********** RN PROF (Subscription changes - archives) - http://list.uiowa.edu/scripts/wa.exe?SUBED1=RADONPROFESSIONALS&A=1 ***********
