Koval Plumbing, Heating and Air Conditioning Inc

George is a rare breed. He shows up when he says, he is honest, and he priced his work fairly. Quality of his work is first rate and I know we can depend on him for quick responses and informative feedback and advise.

I recommend Koval Plumbing for any plumbing/heating needs - big or small.

I own a small business in Tyngsboro. I had a water leak that needed repair. I called Koval Plumbing to ask for some help. George called back the same day and showed up before I closed. The problem was fixed quickly and at what I consider a very fair price. He told me what I need to do next and when I'm ready I will certainly call Koval to do the new install. Thanks George and thanks to your brother too!

George is a hero in my family! He is the only plumber I trust with any job. He is very knowledgeable and a great guy. He is AMAZING! I have called him in on a weekend and he came right over. Thank you George, for all you have done for my family.

I am a small business in town and my A/C stopped working. George was there within 24 hours to take care of the problem. With a very reasonable price.. Thank You

I just want to say how great they were!!! I called for my mother who had no heat and they came out the same day, at the time they said, went and got the part, and put it in the same day!!! I cannot say thank you enough for the service!!!
