Nothing worst than waking up in the morning with no heat at your home . Called on Sat morning at 8:30 and they arrived At 10 ready to diagnose and solve the issue. George knew exactly what to look for and pointed out the problem right away. Knowledgeable, reliable, professional.
I will be using from now on and Highly recommend for you to try them too.

I called and talked to George Koval to give me an estimates on adding a new hot water tank in our house. He agreed to meet me at my house the following day. The morning of my appointment, I called him to confirm and he said ok.

We waited for him and he never showed up. I called, left him a voice message and even texted him. He didn't answer his phone nor answer my text.

He's very unprofessional and doesn't know how to treat a customer.

Don't waste your time calling this guy. If you value your time, don't bother.

We had a really good experience with George. We had him come over to replace an old dishwasher, and the installation process turned out to be quite a bit more complicated than we had thought due to our dishwasher being farther away from the sink than ideal. He managed to make it work, and had a really great attitude about the whole thing, even though the installation ended up being a lot more labor intensive than everyone had expected. He's also a really funny guy! Overall we won't hesitate to have George over again.

We put an addition on to our house this summer which resulted in a much needed 2nd bathroom. We also had a tankless water heater installed. We have a brand new kitchen and the sink/dishwasher & refrigerator were hooked up as well. George Koval was very professional and did great work. We are very happy with the results. I would highly recommend him.
