"Steven showed up and was able to repair our AC after two years of multiple repair companies that could not help. Everyone else said we had to replace when Steven was able to determine that it just needed a quick repair. He was professional and so pleasant. English is not our first language but he was so patient with us. Highly recommend!"

Customers say: True professional

"I have an older furnace that was in need of repair, and Mark did an outstanding job from start to finish. He took the time to thoroughly inspect the unit and explain everything along the way. With winter approaching, needless to say, I was a little nervous about the situation, but Mark immediately put my mind at ease. He encouraged me to ask questions throughout the process and was incredibly patient, even with my daughter (who is basically my mini-me!) watching and asking questions of her own. His pricing was more than fair, and he had my heat up and running in no time. He didn't just fix the immediate problem; he took the time to troubleshoot the entire system and made sure I felt confident that we'd be able to get through the winter. I really can't say enough good things about Mark. It's not often you come across someone who is not only knowledgeable and professional but also genuinely cares about the people he's helping. Thank you, Mark, for doing such an amazing job!"

"My electrician from Cotti-Johnson HVAC was a master electrician. If you get him, you are getting the best. I went with the most expensive work package of the 3 that were presented. First off, it was pricey. I knew that going in. I want Cotti-Johnson to understand that I am serious about a working relationship with them. I feel I have done that with their electrical department. Now, if I need their plumbing or HVAC service, our relationship can build off the first experience."

"Bryce is an excellent plumber, very professional. He installed a booster pump to increase water pressure. He was quick and efficient and the area he worked in was left so clean you’d never know any work was done. He also fixed a few other areas that needed fixing in our newly purchased home. I would highly recommend Blanchard Plumbing. And the price was more than fair."

FAQs for water heater repair or service projects in South-carver, MA

Warning signs include fluctuating water temperatures, a pilot light that repeatedly goes out, unusual noises from the tank, or complete heating failure. You might also detect a rotten egg smell, indicating a potential gas leak, or notice water that never reaches the proper temperature. If your water heater is over eight years old and displaying these symptoms, the gas valve is a likely culprit. Professional inspection is recommended, especially if gas odors are present.

Water heater gas valves are not universally interchangeable. Each valve must match your specific water heater's make, model, and specifications. Important compatibility factors include gas type (natural gas vs. propane), BTU rating, connection types, and physical dimensions. Using an incorrect valve can result in poor performance, premature failure, or dangerous gas leaks. Always consult your water heater's documentation or a professional plumber to identify the appropriate replacement valve for your unit.
