Expert Advice: James demonstrated extensive knowledge about tankless water heaters and provided clear, detailed explanations of our unit's functionality. He answered all of our questions with patience, ensuring we fully understood the system and its maintenance. Outstanding Service: The service he provided was exceptional. He was prompt, professional, and respectful of our time and space during the consultation. It's clear that he genuinely cares about his customers and their needs.

He offered practical solutions that have resulted in improved performance of our water heater. Overall, I highly recommend James from Tankless Industries. 5 Stars!!!!!!"

"QUICK, FRIENDLY, and CHEAP!! First, AJ called me within 30 seconds of me texting him asking for an estimate. I sent him a photo of our water leak issue and he immediately responded. He actually explained that we could probably handle the repair ourselves if we were up for it, instead of paying him or someone else. He then walked us through every step in detail and made sure we were comfortable with the directions. So in the end, it cost us $0 in labor and only a small amount for materials, and really demonstrated AJ's integrity and generosity!"

HL Bowman has been in the same location for 38 years and owned by the same family for over 65 years. HL Bowman is a non commission based company. HL Bowman employees will never upsell you a product you don't need. Dennis and Bryan Enders and his family have deep roots in the Harrisburg community. After 65 years Dennis and family stay committed to giving the community the best possible service and product to fit their needs. HL Bowman has won Angie's List super service award every year.

"Adding to the above review: NEGATIVE STARS 1. The Daikon' ductless mini-split' unit, sold to me by Brian Enders and installed by H.L. Bowman Incorporated, unleashed a deluge that not only saturated the hardwood floor in my dining room but also flowed onto bookshelves and drawers in the room below, drenching 25 family photo albums. 2. The water pooled atop and between each section of my quarter-sawn oak Stickley barrister bookcase. 3. The water seeped inside each section of the bookcase. 4. The water ran onto particularly important and expensive books, framed photographs, as well as four small wooden boxes containing four of my dog's cremains. 5. In past years, water from a second-floor unit emitted sufficient water to cause a 12' by 5' section of the upstairs floor to crash through to the main floor. All furniture and items in that 12' by 5' section were so water-damaged that they had to be discarded. Water ran behind the plaster and into the wiring contained within the plaster walls. I had to make an insurance claim to have that water damage repaired. 6. In past years, water from a basement unit emitted sufficient water to cause an entire wall of built-in cabinetry to be destroyed and have to be replaced. I had to make an insurance claim to have that water damage repaired. 7. In past years, four of the six "ductless mini-split" units have simply not worked. They do not cool. They do not heat. They hang on the wall and blink. 8. Throughout these years of destruction, distress, and financial duress caused by the six 'ductless mini-splits,' Brian Enders has consistently refused to rectify the problem. 9. The FIRST REASON Brian Enders uses to refuse to rectify the problem: When the ceiling caved in from the upstairs unit and the cabinetry was ruined by the downstairs unit, Brian Enders offered substandard assistance. He sent a contractor to my home to spackle over water-damaged plaster, thus sealing water inside the walls. When I saw the inferior repairs Enders offered, I stated that I was going to call my lawyer. Enders said that because I had threatened legal action, his company would no longer serve me. 10. The SECOND REASON Brian Enders gives for refusing to rectify the problems: When the ceiling caved in from the upstairs unit and the cabinetry was ruined by the downstairs unit and Brian Enders offered substandard assistance, I wrote bad reviews of Brian Enders and his company "all over the internet." (Enders words.) Yes. I did, indeed, write bad reviews of Brian Enders and his company, H. L. Bowman, Incorporated, "all over the internet" and will continue to do so until Brian Enders and his company, H. L. Bowman, Incorporated, make the six Daikon "mini-split" units they installed in my home work properly. 11. Because Brian Enders and his company, refuse to help me, I have paid five other companies, & one private contractor, to come to my home to diagnose and repair the six Daikon "ductless mini-split" units. Each one has been unable to do so. Each one says that there is something so faulty about these units &/or the installation of these units that it is impossible to determine what is actually wrong with them. 12. On Saturday, June 22, 2024, I tried to set up a service call with H.L Bowman, Incorporated, using a form on their website. 13. On Saturday, June 22, 2024, I received a text from H.L. Bowman confirming an appointment for Monday, June 24, 2024, with a note relating that on the day of the service, I would receive a call 30 minutes before the technician arrived. 14. On Monday, June 24, 2024, I instead received a phone call from H.L. Bowman informing me that they are too busy serving their VIP customers to send a technician out to serve me. Today is Tuesday, June 24, 2025. H.L. Bowman has still not rectified their financial and material injury to me."
