"My prior water heater, a 50-gallon tank, started leaking after 15 years. I called Streamline to confirm that it needed replacement, and to replace it. I was considering a tankless water heater already, and the first tech walked me through the pros and cons, then wrote up an estimate. Two additional techs came the next day to install the heater and the necessary gas and power lines. The only issue I had was that one of the newly installed gas fittings leaked gas into the basement. I shut off the supply valve and called Streamline, and they came out within half an hour to fix it at their expense. Mistakes happen, and I was impressed with how professionally they corrected that one."

"We had excellent service by Russell Ragan, P-1 licensed plumber, to inspect all our plumbing and to flush out our water heater. We signed up for the monthly plumbing service plan,. So this visit cost less than $10. Great communications throughout. Our #1 choice for heating, air conditioning and plumbing in the Triangle."

"Very satisfied with the outcome. The house was not occupied while this work was being done, so I was not present during much of the work to observe the installation of system & ductwork, but it worked beautifully once we moved in and began to use it, a turnkey experience. Twice since then we've had questions (e.g., Can we move the ductwork in one part of the attic to accommodate new attic stairs?), and both times they were very responsive and came out at no charge to me, despite the fact that the work was done over a year ago. I've interacted with both Mike (the owner) and with one of his technicians, and have been very satisfied with the level of customer care I've received. I will use them in the future for our heating & A/C needs.

"FIVE STARS to Cape Fear Air, Plumbing, and Electrical of Raleigh for their responsiveness and superior job installing a new Trane HVAC system in our home during the peak of the heat wave in July. Unfortunately, our 17-year-old Trane died during this period of record-breaking heat indexes. Josh Pitts, Cape Fear Project Manager, quickly and professionally responded with the right equipment at a fair price with an excellent install team. The installers, JJ and Spencer, did a SUPERIOR job removing the old equipment and installing the new system. The City of Raleigh inspector was very impressed and pleased with the top-notch quality of Cape Fear's installation (I accompanied him on the outside and inside inspection). I highly recommend Cape Fear Air, Plumbing, and Electrical of Raleigh."

"Great service. They came in and assessed the issue and provided options for the replacement of our gaspack. The company was knowledgeable on each option and answered all of our questions. Prior to install we had a walkthrough to double check they had all the parts for the new gaspack, and completed the install of the new device in less time than anticipated the following day."

"Excellent, friendly service. Mike was in and out in no time. His prices are quite good and he was flexible with my requests for upgrading the water heater. He uses one of the top tier quality brands. It was a pleasure working with him."

"Pedro came and fixed my outdoor hose bib that was leaking. He came the next day, fixed it quickly, and thought me how to do it myself. All at an amazing low price. He even did another small job for free. There isn’t a better plumber in Raleigh, I’d recommend him for any plumbing work."
