1 – I can't believe how fast and easy it was to get an appointment. 2 – I love that they confirm the apt. 3 – I appreciate that they sent a text with the ETA of the technician, let me track how soon he'll be here so I can prepare the dogs, and give me a picture of what he'll look like. That is awesome. 4 – got us up and running again in record fast time. I completely and totally recommend Haller!!

The technician listened to my questions, and provided answers that were very helpful. He serviced the tankless water heater, and instructed me as to how to drain the 55 gal holding tank. Very satisfied!

We had an issue with what looked like a tiny drip in the basement, but Nathan who was amazing (friendly, caring and very professional) spent the necessary time checking out all the area. He found a bird had built a nest in the dryer outside vent causing this crazy scenario. He found it and fixed it that same day. 100% satisfied from this service.
