    Drainage pipe replacement handled professionally. Great diagnostics and execution. Their tech named Matthew was nice and arrived on time. Water now flows as it should. Will hire again Superior Plumbing and Heating.

    I was having trouble keeping my house warm, so I called Superior HVAC Service. Ian arrived right on schedule, quickly figured out the issue, and had everything fixed before I knew it. He even checked my water heater to ensure it was working well. Great service—definitely recommend!

    Outstanding Service!I had a concern with my AC unit, and Superior HVAC did not disappoint. Sarah was prompt, courteous, and fixed the issue in no time. She even took the time to clean the unit and check for any potential future issues. I couldn’t be happier with the service I received.
