5 (plus) star service and offerings. So happy with their soft water and RO filtration products!
Great local company and especially like the home service option for salt delivery!
Trevor Waggner is awesome. INCREDIBLE knowledge and very solution oriented! Make sure to give him a call.
Emailed Trevor late on a Tuesday evening in need of 32 bags of salt and had them before noon the next day. Great, fast service!
McGowan water is by far the most experienced and professional water conditioning company around they have highly trained staff in residential and commercial water treatment equipment.
Trevor Wagner is very knowledgable and someone you can trust when it comes to all your water and conditioning needs– I would highly recommend working with him!
Of course I love this place. Grandpa started it, Dad ran it for years, and now my brother has taken over. But I know you won’t find better products or better service anywhere in the area.
Replaced my water heater under warranty and the installation was fast and neat. Would recommend to anyone needing water conditioning equipment.
From the salesperson, to the installer, the experience was incredible, all of my questions were answered, and I felt great about the purchase. The install was professional, and the our payment needs were met. Great all around experience.
Trevor Waagner is so wonderful to work with. He has a low pressure attitude, genuine about helping in any way he can, and follows up with you to make sure you are being taken care of. I would highly recommend him for any of your water needs!
I contacted just to have my softener checked and within the next day Trevor came out and tested the water and made a few tweaks to our softener. He does things in a timely manner and is very polite to people. You can tell that he cares about his job.
Trevor was wonderful to work with. Extremely knowledgeable and friendly. He worked with our company to find a solution that fit our needs. I strongly recommend anyone looking to explore water conditioning solutions call down and ask for Trevor!
Truly great customer service thus far, knowledgeable staff, and we had a very quick install timeline. The installation itself took considerably less time than imagined and the service man showed up promptly. Will highly recommend.
Very pleased with McGowan. They have always been helpful. Most recently they talked me through a repair/reset without a housecall and without charge.
Awesome options and services!! I have yet to personally use McGowan’s services for my own benefit but I can definitely assure you that they are class acts. Trevor Waagner is as down to earth and honest as they come. I can’t wait to utilize McGowan’s services as soon as I get into my own home!
Water system has been awesome, and our service tech John W. was amazing!! Would highly recommend McGowan to anyone looking for a water treatment system.
Everyone was knowledgeable, courteous and professional. They explained what I needed and why based on the tests performed right in front of my eyes. The quality of the installation was excellent and was done quickly. I’m sold on them for any future needs.
