One Family’s story >

“The Duo-14 was very easy to install. It took about 20 minutes, give or take 5 minutes. What sparked my interest was not only the ease of installation, but the ease of bulb replacement. I have had one prior and it did keep smells down and kept my coil cleaner. I am sure this will do just the same or better.” — All Seasons Heating & A/C Inc., VA

“I am familiar with the technology that the Duo-2000 is using and I am very excited to experience the product’s performance. It was nice to feel the quality of the unit when I removed the unit from the package. The backer plate and cover are heavy gauge steel, (not a cheap plastic cover which is all too common these days). The installation was very simple, and took no time at all.” — Efficient Energy Enterprises Inc., MI

“The installation was very easy. It took about an hour or so to complete everything. My wife has asthma and also a bad cough for close to a month now and she has already started to notice an improvement in her breathing in the last week.” — P G Heating & Cooling, MI
