Mark Oliver, Owner

Here’s what our loyal customers have to say about us:


I very much appreciate that you tended to the problem right away and went the extra mile to make sure it was fixed before the July 4th weekend. Thank you.

Your servicemen acted very professional and provided exceptional service. I would highly recommend your company to others. Thanks.

Thank you for all you do for us. You are the best people to deal with! We are fortunate to have you.

I appreciate that you stayed on with us until you found the problem and fixed it. It is not always easy to come into a situation where someone else already worked on it and failed.

We sell products that make your everyday life better.
