Technician, Kenneth M., was very professional and worked with efficiency. Going down into the crawl space in my home is never fun, but he didn’t complain at all about it. I was rather surprised at the cost of the filter replacement. That seems to have gone up significantly since it was last changed.
Wes is fantastic! He always explains things thoroughly and gives us great advice. He takes the time and is very thorough.

I had a good experience with Haller Enterprises, to help resolve a blocked bathroom drain. A quick web search led me to Haller's site, I answered a few questions to request a call-back, and Haller was very responsive with information and scheduling options. Scheduling service was easy, and the team provided updates throughout the process on my appointment, technician eta, and billing. My technician (Darius) was great, calling ahead of arrival, providing a quick assessment of the work, and solving my drain issue quickly, including recommending options to prevent future issues. Thank you Haller & Darius!

Water heater maintenance was superior by Johnathan. Recommended anode replacement. He added a valve on the hot water side to provide for easier isolation for maintenance. Since anode replacement was performed during routine inspection I received a 50% discount on Anode.
Very kind efficient answered our questions with very little disturbance of our morning
