A water heater gushing into a basement early in the morning, and a plumber named Nick at the door that same morning: that is how one recent customer described calling this Norwood plumbing and HVAC company. The customer said Jason took care of the permits and scheduled the building inspector, and the heater was upgraded to a 50-gallon size at no extra charge. The company describes itself as a Norwood-based plumbing and HVAC business offering 24/7 emergency service. It says it was founded in 2009 as a one-truck plumbing shop and added a full HVAC license and in-house HVAC team in 2013, and that it is owner-operated by James A. Dalelis. A customer whose AC quit during a heat wave said James answered the phone himself and had someone at the house within an hour to repair it. When a boiler stopped working on a Monday night, a recent customer wrote, James came and fixed a stuck damper and explained the whole process. A 2026 customer said a new roof unit was ordered the same day, and the old unit was removed and the new one dropped in by crane in about four hours. A 2023 customer said James returned an emergency call within minutes on a Saturday morning after the pipes in a utility closet froze and burst. That 2023 customer later had the laundry closet redone, with tile, a quartz countertop and a shelving unit built by his carpenter. A recent customer said an HVAC system the company installed about seven years earlier needed a new coil and condenser after a leak, and that two other HVAC service technicians said the coil had been installed too low to the furnace. A 2025 customer who booked online for a same-day visit waited all afternoon, then got a text moving it to two days later. A 2024 customer said no one mentioned a $250 service call, paid $300 after being told the AC system was old and unfixable, and never received the promised quote for a new system. Massachusetts lists its plumber licence, 4865-PL-C, as active.

Very efficient and professional job! Replacement standard outside faucet with a frost-free silcock to help prevent freezing and burst pipes during winter weather. How wonderful that they used an upgrade instead of a basic faucet. Thank you. Susanne Taylor Damon
Highly recommend this company! I rarely write a review, but my experience from start to finish is worth mentioning. My water heater was gushing water into my basement early in the morning so I called Jason Dalelis Plumbing out of Norwood and got an answer right away. Jason answered my questions and gave an estimate over the phone for a couple options to replace the broken water heater. He was up front and didn’t try to upsell me extra stuff related to my older 1880s home. The plumber, Nick, showed up that same morning and assessed the situation, took pics and answered my questions. They offered a same day repair to replace the water heater or next morning upgrade to a tankless option without charging extra for it needing to be fixed ASAP. Jason took care of the permits and scheduled the building inspector to come at a convenient time for my schedule. The repair was done on time and ahead of schedule. They even upgraded my water heater to a 50 gallon size at no extra charge and updated some fixtures in the basement. The work area was left clean and tidy. Thanks for your solid work, I’ll definitely call you again for any future repairs.
I had this HVAC system installed by this company about 7 years ago. I expected it to last much longer before experiencing a major failure, but the AC stopped working due to leak and required a new coil and condenser. I was disappointed by the lifespan of the system and expected better durability for such a large investment. Based on my experience, I can’t recommend this company. I had two professional HVAC service guys tell me the same thing that the person who did the install tell me the coil was installed improperly (too low to the furnace). The coil keeps freezing and the AC doesn’t cool down the house. Every year or two I service the AC. The second year they had to refill the refrigerant therefore the leak happened at least two years from install.
Called James after our AC quit on us during a heat wave. He answered the phone (not a call service) and had someone at the house within an hour to repair it. Tech was friendly, professional, and very thorough. Glad we called James!
James A. Dalelis Plumbing & HVAC responded to our initial call within 2hrs. Nick & Elias were very polite and professional. These gentlemen troubleshot our Goodman central A/C unit and replaced the capacitor and charged the unit with Freon. The A/C unit is now running at full capacity, once again cooling our home. My Wife & I are Very Pleased with the professional service rendered by Nick & Elias of James A. Dalelis Plumbing & HVAC . We DEFINITELY would recommend this company and these Gentlemen for any and all plumbing needs. Thank You 🙏 Paul & Joan Ellis Norwood
