"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."

"Everyone from Delta Heating & Cooling were highly professional and courteous. Everything was done as quoted. Michael, the sales rep came back during the install to make sure everything was going smoothly and afterwards to answer any questions. Kelley at the office was very nice and responded quickly to my requests. I would recommend Delta to anyone looking to have their HVAC system replaced."

"I called in the morning and Chris came out in the afternoon, when I was available. He explained and showed me what the problem was. He didn't have a new water heater on his truck so Tim came about 45 mins. to bring one. Installation was fast and Chris was very professional. They will be the first ones I call if I have any other issues."

"Pedro was fantastic! Very polite, punctual and provided exceptional service. Not only did he fix everything I asked - he took the time to teach me how I could do the repairs myself. I’m glad that I found a plumber that I can trust. And I will recommend him to my neighbors!"

"Excellent,prompt,courteous and professional service all the way from initial contact from ARS quickly reaching out to me to set up an appointment to the work done by their technician. He arrived on time, was friendly, professional and proved to be very knowledgeable and skilled in his profession. He quickly identified the problem with my water heater and had it fixed in a short amount of time. I am very impressed with ARS and will use their services again in the future for any plumbing needs. I highly recommend ARS."
