"Such great service!! My water heater went out in my rental property and they were able to hop on the phone with me right away and offer me a quote. Within the next 2 hours someone was at the property - they removed the old water heater and installed a brand new one and were on there way. Cobra Rooter & Plumbing was professional and quick! Will use again in the future."

"I have had worked done by Pepe from Reddi Services several times and he has always been great. He has fixed bathroom fixtures which were incorrectly installed by other plumbers, replaced a sink, water heater and water softener with the expertise and professionalism you'd expect from your plumber."

"They showed up on time, made a minimal mess, did a quality job replacing 2 complete heat pumps systems and were very good about explaining everything along the way. They even filled out the rebates and sent them in."

"Glenn was an incredibly knowledgeable educator, above and beyond the other companies we spoke with. He also really didn’t want us getting anything but the best and wholistic options for our family’s situation and home. The warranty was great too! We had a water heater removed and replaced, reverse osmosis filtration installed, and a whole home filter and conditioner fitted. The water tastes great from everywhere in our home! The plumber on site was friendly and quick. 4 months later everything is working perfectly. Glenn was fast and constant with communication the whole time. If you need any work done related to water- highly suggest giving Aquaco and Glenn a call."

"Hired to Install and maintain Hot Water Heater. Provided prompt information and came ahead of scheduled and completed the Installation, and while there, performed a maintenance of my inside plumbing to see if there were any problems! Definitely would recommend this Company, their pricing for service is very comparative to other Plumbing type companies."
