If I could give more stars I would. Nathan worked with me for months getting everything figured out and making sure every question I had was answered. Please note that the process itself did not take that long, I just had plenty of questions and wanted to truly understand everything that would be happening. I worked with quotes from another company when I was working with Haller/Nathan, and while the other company got annoyed with my endless questions, Haller/Nathan was there with all my answers. At every turn Haller blew the competition out of the water, both with price and customer service. I was thoroughly impressed and happy with the whole process start to finish. Everyone I was in contact with in this company was absolutely fantastic.

The technician was very thorough in checking the installation of my heating system. He found some issues with the installation of my hot water heater. He called his supervisor and explained the situation and asked for a plumber to make the necessary adjustments. The call center called me so this issue will be scheduled for later this week. I was impressed by the technicianโ€™s thoroughness. Definitely a five star service. Thanks to all involved.
Westley was great. Very professional, explained everything he was doing and assessing. Also helped me understand my options. Highly recommend

Haller was able to get a service technician out to us quickly despite it being new years eve. Their technician Shane was very communicative and went above and beyond to thoroughly diagnose and resolve the issue, as well as provide some advice on keeping our system in good shape and wiring efficiently.
