ABOUT BUSINESS OWNER

Biff Mahn's own introduction into the business came at a tender age of 10. He began holding flashlights for the men and sometimes getting into crawl spaces, in between floor joists or anywhere else the bigger guys couldn't fit. He didn't collect a dime but gained priceless knowledge. He began earning a paycheck during high school, working summers as a plumber's apprentice. He's been there ever since.

We originally had this company out for a wellness check on our geo-thermal system. That was $500. 2 months later our compressor went out. We called them back. When the compressor finally came in they hooked it up wrong and tried to charge us for their screw up. I called them and explained that I didn't think we should have to pay labor for something that they screwed up. They took money off the bill but it still cost us $3200. A month and a half later the connection is leaking to the compressor that they installed and now they are telling us they don't work on those anymore. We've spent $3700 with this company and now they don't work on those anymore! Terrible way to do business. They won't even warranty their work.
