    Anthony and his team just replaced both my heating and a/c systems. Professional, efficient, friendly and finished the job ahead of schedule. Would not hesitate to recommend them for any plumbing or HVAC needs. I will have them continue to service my new systems.

    Reliant installed a new Viessmann boiler, 60 gallon indirect water heater, and water filters for my home. They removed the old boiler and water heater as well. The job was performed efficiently, on time, on budget, and professionally. Working with Reliant is a pleasure. They made sure all systems were working as needed and came in to fine tune right away. They also installed a mini split for both heating and a/c in our upstairs bedroom which runs perfectly. They are a pleasure to work with - do not hesitate to do business with Reliant.

    We’ve used Reliant Plumbing & Heating for multiple projects and services over the years from mini splits to a water softener and maintenance and it’s always been a great experience. They are fair, knowledgeable, and an easy company to work with.
