I am no longer in business. I bought all this equipment in 2010. I also have 10 Vent caps and two 20 ft Duc-Bloc vent covers for sealing air ducts. All equipment in excellent condition and guaranteed to pass calibration. I also have the field cal plate for the duct blaster. I would prefer a local buyer so I don't have to ship this equipment. I am in the Monterey Bay/ San Francisco Bay area. Thanks for your interest.

I'd be interested in your combustion analyzer, and would gladly pay for shipping. I've made you a "friend" so we can exchange private messages.
If you still have the Duc-Bloc covers, I'd love to buy them. Contact me via email: email@example.com
