I had a bad experience with ASI's Heating division and wrote a one star Review last month about how their tech told me I needed a $400+ part for my furnace; but when I got a second opinion, the other (more honest) company cleaned a couple of parts on my furnace and it immediately came back on and has been running very well ever since.
I received an e-mail from ASI management offering me a Plumbing Service Call and Diagnostic Check-up, at no charge to 'set things right' and give them another chance to earn my trust. It just so happened that my water pressure had become very low that week (to all my faucets and tubs) so I accepted ASI's offer for a diagnostic evaluation from their Plumbing Dept. After checking many things, ASI's tech told me I needed to replace four items to correct the problem and his quote was for an amount just under $2000!
Long story short, I called another plumber to get a SECOND OPINION. Louie from Louie's Plumbing came out and within 5 minutes discovered the problem and corrected it. NO parts needed!
He said, whenever I see a whole house water softener, that's the first thing I check. He shut off the by-pass valve and Voila, all the water pressure immediately came back on thru all my faucets and tubs. That faulty water tank was exchanged for a clean one from my water service company and I have had perfect water pressure ever since. All I can say about ASI, is if you want an expert opinion in Heating or Plumbing and want to save thousands of dollars and get the job done right, get a SECOND OPINION from another company.
