"I would like to rate I & A Piping, they finished my 3-Tankless water split system heaters. He has finished the work and we are very pleased with his professionalism and skills. The job was completed when scheduled and within budget. I could not find one flaw in his service. Thank you,"

"Very nice and polite. The city is doing a lot of work and gave us brown water. We went with a sediment filter, then had him come back and also install a carbon filter system after researching city tap water. Once the water heater goes I will have him replace it and put a charcoal filter on the hot water side too."

"I had the equipment replaced, a brand new, super high efficiency, fancy, lovely stuff. It's a central air system, and it's Lennox equipment. It's high efficiency. You can get it for less than that, but you're not gonna get the high efficiency quiet and all that kind of stuff. I had received other quotes which were like more money for the same system. I have been using them since 1986. No complaints. They do their thing, and I can't fault them. I have a service contract with them for this."

"Andy was quick, clean and very professional. I only requested the concrete and driveway and he noticed how much mildew was growing on the side of my building and with hesitation power washed that as well. Thank you for your services, I would definitely recommend his services to my family and friends."

"Antonio, at Greenovative, was great. I really enjoyed his professionalism. He and his crew found creative ways to decrease the price of the project. We are happy we gave Greenovative this project. Honestly, we will use them again."

"Very positive experience with Tim and his crew. We have horrible well water, and there were time constraints due to real estate purchase. Everything was done within the specified time-frame, neat and professionally. Responsive to inquiries, and helpful in educating during the process. They offer competitive pricing, and there is no pressure. You can tell that their main goal is to provide safe water to their clientele. It has been a few months since completion, and it is nice to have peace of mind that our plumbing, fixtures, and appliances are protected by some of the best equipment on the market."

"They did a great job! I knew I wanted a water filter for the house and drinking water since we were moving out of NYC and their awesome water to an area with a crappier water source. And I was about to have a baby! Anyway I did endless amounts of research, including multiple water companies that do their own install, and direct to consumer ones where I could just buy a system and install it myself, and after thinking about it for months (literally), I finally went with QWG. We worked with Maria (who is absolutely awesome) and the cost was reasonable. Between what they offered and how pleasant the experience was, I’m glad I picked them. We have a whole house filter and an RO system that they were able to hang in the basement so it doesn’t take up space under the sink, and it’s hooked up to both a faucet at the sink and the fridge as well. Exactly as I wanted. It’s been a couple months, and the water’s great so far. The support is great too, which is big. Can’t speak for long-term usage yet, but so far we’re very happy! Thank you!"

"We highly recommend Ultra Pure. Al is a true professional who cares about his clients. We were concerned about our existing water treatment system since I have a lung condition that makes me vulnerable to certain environmental waterborne pathogens. Al analyzed our system and tested our water. He explained how to improve our RO system in terms that made sense to me and to my husband, who is a chemical engineer. Given my respiratory issues, Al thought we might also want to consider an air purification system. That was an excellent suggestion. So we improved not just the water but also the air in our house. Al delivered everything himself and took the time to explain how to operate and maintain the systems. I’m breathing better already!"
