Carlos did an excellent job in servicing our water heater and forced air furnace. He was very professional and very thorough and all the steps he took to make sure our two systems are operating properly. I enjoyed the additional information that he provided and showing how both systems are operating properly and the maintenance that they provided to ensure their continued proper use.
George Gray
We have been with Haller for at least 8 years. And the service they provide has been excellent!
Deb McHugh
Excellent service! Glad I have a maintenance contract with Haller. Daniel was amazing. Excellent work replacing our water heater and the best customer service skills. Thank you!
Matt Carper
Triangle installed our small commercial system in 2016 and we've been experiencing failures nearly every year since. We kept trying to get them to send somebody to root cause the system for the failures, but every time they would just come out and replace the same blown fuse or a wire and send us a bill for ~$1000. We tried communicating our need for a real solution with the main office, but it just sent us to a call center in California. Finally gave up on them and had someone from Haller come out to look at the system, and on the first trip they found multiple errors in the system set up, fixed those, and sent us a bill for about 1/3 the cost. At least the positive here is that we found our new, go to HVAC company, with Haller. Thank you, Hunter!
Paul Nicholas

⭐️⭐️⭐️⭐️⭐️
I cannot say enough good things about Daniel Sprague and Haller. I called just before noon for an emergency sewer line issue, and despite it being midday, Daniel arrived around 8:00 PM and worked for nearly four hours to fully resolve the problem. He shared that he had already worked a 16-hour day, yet his professionalism, patience, and dedication never wavered.

Daniel was knowledgeable, informative, and took the time to explain what was happening and what needed to be done. He approached a stressful situation with calm expertise and genuine care, which made a huge difference. His work ethic and commitment are truly commendable.

I would highly recommend Daniel Sprague and Haller to anyone in need of reliable, high-quality service—especially in an emergency. This level of service is rare and deeply appreciated.

Thank you Joshua Kahley for fixing my breaker and restoring my electric
Jeffry Stauffer
