Knauer is always very responsive .They are very fair and honest in their appraisal of problems. I use them for both heating and plumbing issues.-for over 15 years. I once had a toilet that overflowed on my third floor and they came within 30 minutes to fix it and basically saved my home! We recently lost the heat in our home and i feared we would need a new boiler-an expense i dreaded during this current crisis time. Knauer replaced a valve and it was fixed! I highly recommend them.

We have been using Knauer Plumbing, Heating & Cooling for almost 30 years. They are friendly, accommodating, clean, professional and never try to overcharge or sell you unneeded services. They explain what the problem is, do an excellent job taking care of it and are efficient without cutting corners. I always feel confident in their work.

I am so glad that I contacted Knauer...The hose from our kitchen sink faucet began leaking. Your employee Jordan noted that our hot water outpour was also very thin. We discussed and I decided to buy a new faucet...it was installed. AND the hot water Outpour was back to normal!!!! [I had been told that the Problem was the water pipes in my home we’re so old and narrowed.] I am so glad that I called Knauer!

So much for costumer service in this place.
We called because we need it a Plumber urgently. So we also the lady if she had anyone available she said the closes was 3 weeks. Then we ask again is there anything you can do to send someone or another place we can call to get a good service. And with the worst attitude she said to us. GOOD LUCK WITH THAT as she laughed at us. It was so rude and unprofessional, to talk like this to potential clients.
Review Update: WOW. Thank God we did not went with this company, What a Horrible and Unprofessional response. Let's get some classes of customer service

Have been using them to service our furnaces and water heaters for the last 15 years. They are always timely when it's an emergency. They do great work and are up front about pricing. The ladies in the office, and the repair people are always very nice. I would definitely recommend using them.👍

I recently had a very good experience with 2 young gentlemen from Knauer. Jordan and Nick, they were prompt, polite and pleasant. It is wonderful to see young people learning the trades. They are definitely good will ambassador for the East side family business. We have been dealing with Knauer for over 25 years and are very satisfied with the professionalism that is shown and the quality of their workmanship. I would highly recommend this neighborhood and family business.

Today I had Nick and Jordan snake out my tub. Young professionals that answered all my questions even removed an old shower head for me. Very patient and got the job done. Keep up the great work guys. Thank you!

We highly recommend Knauer Plumbing as they have completely redone the plumbing in our old home from all new copper piping to new kitchen sink, dishwasher, basement shower, and two bathrooms. Buzz is knowledgeable and did a very neat job of the plumbing. We have enjoyed working with him as he is pleasant and easy to have around. This summer a new furnace installation went smoothly. (We didn't tell them that this new furnace actually cost $500 less than the one did 21 years ago). The furnace we had before was actually oversized and Kevin was very careful to calculate the size of the new furnace
