Recent Review: we currently use the contract agreement for our HVAC annual service plan. After having a plumbing issue with the upstairs laundry, and having to call out another plumber on a weekend to snake the house. We contacted Haller that monday, who came out and gave us a quote the next day to move washer and dryer to basement and install new plumbing into to main line in the basement. They showed up promptly at 7:30. After flushing all water through line, they tapped into main sewer line only to realize the sewage was backed up. Thankfully my husband was there to help. They looked at our sewage pump grinder to realize the floaters failed, causing nothing to be pumped out, which is where all the issues stemmed from with water backing up on the second floor laundry. it was a mess to clean up. They called out additional assistance. The parts were not available for the pump, but the guys helped my husband clean up inside and outside and instructed how to manually turn on the pump until the parts came in. We also had new new energy eff hot water heater installed same day after realizing our was not installed to code. they were only supposed to be there 3 hours , ended up 2 servicemen for 9 hours , very professional, they didnt even take lunch, i think at one point my husband offered to get somehting for them, but they declined. It was a long day for them, and not one complaint.
