Diana Roemig
Our well water system wasn't working naturally on Friday. So we called hoping to get an appointment asap. They came out right away and got the water back on. More during the next couple of days to finish up. I have a 130yr old house so some things here aren't standard, lol. John expertly diagnosed the issue and worked to get parts. He is now my favorite plumber!
Bill Schwarz
Fast and good evaluation of my A/C unit.

Great customer service, prompt, professional, very knowledgable
Perley Allen
Thomas Wolf did an excellent job. He was very helpful and went over everything in detail. No repairs or part replacement was needed at this time.
Brian Hazlett
Great service as always.
Annette Coffman
Two different technicians, a plumber and an electrician, came and serviced our HVAC and water heaters. They were very skilled and efficient. We would highly recommend Haller.
Mark Newsome
Carlos was very friendly and professional during his recent HVAC preventive maintenance visit. He took the time to review the results, and offered suggestions on some issues. Thank you, Carlos.
Rob winslow
Eric and Donnie did a fine, professional job. Only thing I'd change was the sales person should have asked about keeping our existing wifi thermostat. At the end of the installation Eric had to replace ours and remove theirs.
Kathy Maloney
Dan was very knowledgeable & explained what was needed to replace our water conditioning system. The replacement was done quickly & to our satisfaction.

Darius was the best ever. He told me what needed to be done. And what I was told from another company was different from what he saw. I appreciate the kindness and truth that he has shown. Thank you
