Eckhardt & Johnson was a plumbing service company before the oil burner was even introduced. We helped bring modern plumbing and heating technology to Manchester, New Hampshire, and surrounding areas almost 100 years ago.

Today our full-service, commercial/industrial plumbing and HVAC service departments provide both scheduled maintenance and emergency service 24 hours a day, 7 days a week. We always stay on top of the ever-changing technology; our technicians are factory trained and licensed to service most of today’s commercial plumbing and HVAC equipment.
