Excellent service! John worked with us to get our Aqua Hot up and running, was very responsive to our inquiries and provided great customer service – thank you so much!

John an his crew at Heat My RV worked on my AquaHot unit early this week, and I could not be more pleased. I had some people look at and work on it in the Seattle area and I was convinced that I was going to need a re-built unit put in my RV (which is our fulltime home). Talked to John to set up an appointment and then drove my home from Seattle to the Denver area. They were able to fix my AquaHot for much less than putting in a re-built one. It is so good to work with a business that has integrity and will do the right thing for the customer, even it if means their will not get paid as much.

I sent my aqushot to john to rebuild. It came back very timely and in excellent condition. It looked new. I had a little difficulty getting rewired. I call john and he explained what to do. That worked out really good. Had a hard time getting all the pumps to purge and prime. John explained what to do and that worked out. I started it up and everything worked as planned. I have asked several rv shops about working on aquahots. Nobody would. To difficult. John will always be my go to guy.

If your having Aqua Hot problems, this is the place to go. I traveled all the way from Michigan to have John replace my Aqua Hot. John and his team saved me almost half the cost quoted by other AQ repair centers. Outstanding Job John. Thanks Much.

John is probably the most knowledgeable person on aquahot boilers for rv’s. He has done service for us twice now on our 2010 itasca class a and I can say without a doubt there are none better than he is. He is expedient and fair and knows his stuff!

John and his company do great work at a reasonable price. I have worked with many aqua hot techs over the years, and John is by far the most knowledgeable in the trade.
