Jason from Haller-Electric did a great job troubleshooting an issue in our old home. Quickly diagnosing our issue and solving our problem, and he did so with a positive, conscientious and professional attitude. Well done and thanks!
Eli called and was here on time for mi yearly plumbing inspection.He was a pleasure to work with.He showed and explained wahar was needed to correct.He had the parts and was able to do the job on the spot.I will ask for Eli again.He represented Haller very well.
Shawn was excellent as diagnosing a problem that was not previously identified by other technicians. He explained it very clearly and was doing so in our best interest. He was not pushy or come off as “a salesman”, just letting us know what the issue was. I will definitely be requesting him to do all future maintenance and repairs!
Excellent service and explained options very well!

Haller has a solid offering overall and I like they have many different disciplines. Jesse Brubaker did a great job doing my semi-annual review of my key machines including two air conditioners and a water heater. Excellent work all around!
The technician, Eric , called in the morning of my ac and furnace installation to let me know he was on his way. Upon arrival he and Connor reviewed the process for the day and layed down plastic to prevent damage to my floors. Another gentleman joined them at some point to complete the job.

;1/1The gentleman that came Jesse B to look at the reason the furnace wasn't working took time to show me and explain all the things he found by using a camera. We decided to purchase a new furnace and setup the installation. The ( 2DS ) I called them both had names started with Ds. We're very knowledgeable and explained everything they were going to do. They were very careful moving things in and out of the house and Covered the floors. Did a very neat and clean job. I would recommend Hallers to anyone.
Jonathan was in and out in less than a half hour and did an excellent job on both projects he worked on. There was no mess when he left, he did a great job cleaning up after himself.
