Our business prides itself on quality work and customer relationships, which is our flagship business platform. We offer a wide range of services such as heating systems, natural gas and propane, all aspects of plumbing as well as water quality testing and the corresponding filtration system from resulting test.

"Dave from Calzini's Plumbing and Heating got me through a hard time when I couldn't get anyone else to provide service on short notice. As a landlord, I had to replace a hot water heater for my tenants as soon as possible. I had to shut the water off and they were extremely upset about it. The only one that responded and came out right away was Calzini's Plumbing. They arrived within an hour and were out within an hour after with everything functioning perfectly. It was in the evening so couldn't get a permit that night. Dave from Calzini's arrived early the next morning to have a permit pulled and all was good again. I can't say enough about this company and would recommend Calzini's Plumbing and Heating to anyone for all your service needs. Thanks Dave Calzini!"

"Dennis did an excellent job replacing our electric water heater! We noticed our old one leaking one evening, and Dennis was VERY fast to respond to my Angi request for service. He was out the next day to install our new water heater and arrived promptly at the promised time. From start to finish, Dennis completed the work in just over 2 hours. He cleaned up the area nicely and took our old water heater with him. A+ 5-Star service for sure! Would highly recommend this friendly professional for your plumbing needs. :)"

Water treatment & purification system repair or services FAQs

If your water softener is over 10 years old or if repair costs approach the price of a new unit, it might be time to replace it. Most water softeners last between 10 and 15 years. Replacing an aging unit can improve your water quality and help you avoid frequent repair costs. For a newer system with minor issues, repairing may be the best option. Consider the age and condition of your system to decide what's most cost-effective.

Water treatment systems remain dependable for 10 to 20 years with proper maintenance and care. A well-maintained system secures full performance by following a scheduled upkeep plan and professional inspections. Consistent maintenance guarantees continuous water purification, ensuring that the system operates at its peak efficiency and delivers high‑quality water throughout its lifespan.

Faulty water softeners exhibit clear symptoms that signal the need for immediate attention. Noticeable mineral build-up around faucets, discolored water, dry or itchy skin following a shower, and altered laundry texture indicate that the system is underperforming. Recognizing these issues early and addressing them promptly prevents further damage and maintains optimal water quality. Early intervention ensures that your water system continues to operate reliably and efficiently.
