"Anthony was wonderful. Very nice to deal with and talk too loved him. Highly recommend him! And his team of guys were great also. He came back to do our gas fireplace for us also. His pricing is great! And great job done. It was supposed to be two days to do the central air he asked to stay later and was done in one full day. Like I said Anthony's the BEST!!!

"Came promptly at appointment time
Completed the hot water heater flush and set the temperature for me.
Checked all plumbing connections and made recommendations about what was good and what needed attention
Gave me a written estimate of what recommended repairs would cost if I chose to do them.
No pressure from them to do them now.
Very courteous and pleasant.

"If you had asked me that day was I happy, I would have said yes. However, on 1/31/17 I had no hot water. I texted the owner of the company, but received no response. I then called the office, and the woman that answered the phone said the owner was unavailable, but someone would call me back. No one did. I had to call another plumber who cleaned out the damper and charged me $95. Still Holzhauer did not get back to me. I then sent an email during the week of 2/13/17. I didn't receive a reply. Finally, I sent a letter via US mail on 2/16/17. Then, on 2/17/17, the hot water went off again. I did not call Holzhauer back, as they did not respond to my previous requests. I had to pay $435 for a new damper. In addition, the automatic feed for water was putting too much water in the tank. That had to be drained. The spigot attached to that was leaking, and had to be repaired as well. This system is under a year old. I feel that Holzhauer should have repaired any issues without question."

"The company was very responsive to my need to fix a gas leak in my basement.I called them one night and the next day they were there.They were late but owner called to notify me of the tech(also an owner) running late so I was fine with that.I liked that the owners are the ones doing the work,not untrained techs.I initially had one gas leak I knew of but the owner found a second one.They gave me an estimate I agreed and they got to work.The work was done professionally and they even rerouted the gas line for me while fixing the leak.All in all very good experience.Look forward to working with them in the future."
