Worked on my heat pump for the central air and stood until the airflow was right
Haller Enterprises has been fantastic. I switched to them recently because we continued to have issues even after my last provider came here and invoiced us a number of times

There were so many things that Haller uncovered that my last provider really should have done and should’ve been done. I had also given my former provider a five star review, but this teaches me a lesson.
Sometimes you really think you know what’s good just because people give you quick service but it doesn’t always mean they’re gonna solve your problem.

Haller is quick, very professional and very detailed about what my problems are and what was not done in my home but should have been

I guess you don’t know what’s good until you receive better
And just to visits, my gut tells me that these guys really deserve six stars or more
Great customer service and honest recommendations!! Very helpful!
I want to Thank Thor again for his excellent work on taking care of several electrical issues that needed to be taken care. He had to spend over 13 hours and in very hot conditions, to correct the sloppy and careless work from whoever the previous owner had do lighting work when they remodeled. They had left live wires and junction boxes open. I initially was only getting a ceiling fan with a light installed from scratch until he showed me pictures of the wiring for all lights on the 1st floor in my crawl space attic.
James , did a great job . I highly recommend Haller.

Complimenting Haller's tech Jonathan Avila who has provided installation and maintenance services for my buildings many times. His concern for customer needs is evident right from the start. He wants to know how you think your system is doing. His work is very thorough backed up by photos of each thing he found that needed attention. I had an appointment mid visit
but Jonathan clearly explained everything to my wife backed up by his photo record.
I was able to review and understand his work later w/ the photos attached to my digital receipt.
My estimates were just as thorough. I am glad Jonathan is our service tech.
Darius was thorough and tried to think of how to isolate my problem, which she did after testing out a few options. I was very happy with my service.
