My central vacuum wasn't working properly and I figured that it was just the metal wand that needed replacing. I wanted to shop local, so instead of going online for a replacement part, I went into Vacuum Chek. And I'm so glad I did! The owner was so knowledgeable and helpful. He identified the true source of my problem on the spot and gave me a good deal on a refurbished powerhead (the true source of the problem) and replacement parts, plus he also provided some good tips on improving my vacuum's performance. It just shows you that there's no substitute for good customer service and helpful information.
