Get matched with top tankless water heater installers in Swampscott, MA

"I called Viscarello Plumbing and Heating when I had a leaking water heater. Chris looked at the job and recommended a very efficient tankless water heater. I decided to make the investment. Chris and crew installed my tankless. Now, showers never run cold-hot water on demand. I use less water- warms water up so much quicker in my 110y/o house. In July, with tankless system running sinks, shower and washer, my gas bill was $20! I also really like the way the tankless was mounted on the wall. We gained more space without the old water heater in the way. Best of all- nice neat work, no leaks and no mess. Since then, Viscarello Plumbing has plumbed my new kitchen, laundry room, replaced old pipes and replaced radiator valves. Rates are average-but work is above average."

"Great service at an affordable price. Had a new water heater installed. Felt confident in the selection of the water heater and the workmanship. Work completed in a high quality way at about half the price others quoted."

"Replacement of 2 heating and a/c systems. Went very well. Professional, courteous, and thoughtful."

"They were very fast to respond to my call and were able to send someone within two hours. The replacement of the hot water heater went well. For the water pipes they use copper crimp fittings instead of soldering so it will be interesting to see how that holds up over the years. My only concern is how they ran the gas line. They use Gastite CSST which is fine, but the CSST is run so it goes downward then back up and then downward again before it enters black pipe that has a moisture trap. It seems to me that if there is any moisture it will end up in the CSST instead of the trap. In addition, there is a pretty good bend in the CSST right before it goes into the trap section. Also, Teflon tape was used on the all the joints instead of joint compound. I think I will get someone from a different company to come in and take a look at it."

"Installed furnace on 1st floor and water heater on 2nd floor. Professional, clean and extremely thorough. I will definitely be using them in the future."

"I recently had a brand new HVAC system installed for both heating and cooling, and I couldn’t be happier with the experience. The team at Comfort Professor was extremely professional from start to finish. They worked efficiently, paid attention to every detail, and left everything spotless when the job was done. The cleanup was perfect, which I really appreciated. Highly recommend them if you’re looking for quality work and a smooth, hassle-free installation!"

"This was an emergency service call. Main water supply pipe from street to our house had failed. They responded to call within 45 minutes, evaluated issue, gave us price, Within another half hour equipment showed up. Staff was friendly professional and efficient. Start to finish from initial phone call to replaced main with running water re-established was just over 4 hours. Really impressive company with great customer service. Thank you!"

"Ken was a great person to work with and provided excellent service! I highly recommend him for any plumbing or furnace/thermostat work. I will definitely be working with him again."

"These guys are great. Water heater broke and was leaking all over the cellar. They replaced my water heater and had everything done within a couple of hours. Highly recommend them and I will definitely use them again."

"Replacement was urged by technician after routine inspection of heating system. Water heater wasn't part of the service but, tech checked it anyway. Nice enough of him to do that. After showing me his concern (legitimate) I asked for a quote to replace. Outrageously expensive considering cost of materials. Later learned techs are incentivized to sell service and parts. Dropped them as my go to plumbing and heating guys. Water heater still working 3years after urgent replacement was quoted"
