I live in a house with a well. Since I moved in 5 years ago the water pressure has been lower than I would like. Last year I called a plumber and he did a filter replacement and adjusted the pressure valve, neither of which helped. The pressure started getting worse the last couple of months so I called AVS based on Google reviews and recommendations. They came out on time (actually 5 minutes earlier than the 2 hour window I was given!) and quickly diagnosed and fixed the problem. Water pressure is now high and exactly what I was hoping for. Great service!

I've had multiple jobs done by AVS including a new water main shutoff, gas line run for a new stove, and an emergency clean-out when my utility sink was filling up with water. They have been consistently professional, punctual, and competent. Prices have always been very fair for the work done as far as I am concerned.

We have been using AVS and Mike Kastner for more than 20 years, and everything they have done for us has been professional and timely! They have always had our highest recommendation!

Needed a plumber on Saturday of Christmas weekend or we would be without water for the holiday. I called Mike and he was at our house within a half hour. Fixed my problem for a very fair price. I will use him again for any plumbing issues and I recommend him proudly!

We have been using AVS for years. They are a "6". They are reliable, efficient, courteous, helpful, and they do excellent work. If there is a major issue they will deal with it that day, even though they already have a full schedule. I have referred them to numerous people. They had to repair numerous plumbing problems created by the contractor's plumber. We used them to do the hook-up when we had to replace our well; to do gasline work in the kitchen and greenhouse. I couldn't be happier.

Mike has done great work for us both in responding to a flooding emergency (blocked drain) and in replacing our old copper system with PVC. He's always personable and professional and we've come to think of him as a friend.

I moved into a house in an area that has very hard water. I decided that I had to have a water softener. I asked one of my neighbors if he had anybody to recommend. He said he did and that he had had a water softener installed by AVS Plumping and that they had done a very good job for him. He gave me their telephone number and I called and made an appointment. The owner of the company came out, looked at everything and told me that most of the plumbing for the water softener had been installed and therefore the plumbing job would not be very involved. Thus, I made an appointment for them to come out and install my water softener.

A very pleasant young man, Jared, came out and set about doing the necessary work. Within about three hours, I had an installed and working water softener. Jared was very thorough about the way he did his work. Everything was neat and cleaned up when he finished. And, the bill for the work was very reasonable. I highly recommend AVS-Plumbing. They do a very professional job for a reasonable price. What else can a homeowner asked for? It is very nice having condition water rather than what I had before.
