      Abe the service technician and the lady who scheduled the repair are very efficient and a pleasant company to deal with. We called 4:50 pm Thursday and they came approximately 10 pm am Friday morning (believe they’re plenty busy) it’s a well ordered company. Abe diagnosed the issue he is a very knowledgeable repair technician who has a delightful personality. The gas valve was replaced that rarely fails; we have our heat back! It’s expensive to have a boiler repaired. We do recommend Hellgate Plumbing, heating, and cooling for all your plumbing needs. Thanks

      Honestly, consistently impressed with Hellgate Plumbing. Always able to book immediate appointments, they're super responsive, and let you know who your tech will be ahead of time. Henry fixed my broken garbage disposal and knocked out another random problem while he was here, and was super friendly and considerate of my home. I'll send my friends here, for sure. If you've got a home in their area, seriously consider their membership club, it's saved me a few times, completely worth it.

      Our technician, Sinjun, was very thorough in inspecting our AC system. He took the time afterwards to go over his findings and suggestions on repairs to keep it running great. We really appreciate the "no pressure" approach. He left us with valuable information and we will certainly use them for our heating/AC/plumbing needs in the future.
