Laars Heating Systems operates as a manufacturing headquarters in Rochester, New Hampshire, serving residential and commercial customers across the Northeast and beyond. With a rating of 3.9 stars from 52 verified reviews, the company specializes in boilers, combination boiler-water heater units, water heaters, and pool heating systems backed by more than seven decades of industry experience.
What distinguishes Laars is their integrated approach to equipment lifecycle support. The company maintains a parts storefront, rebate center for both US and Canadian customers, and a network of authorized service centers nationwide. Their RightSpec sizing tool helps homeowners select appropriately scaled equipment, while the Factory Training programs ensure licensed technicians stay certified on current models.
Customer narratives reveal responsive service outcomes. When Harley Cox faced delays receiving a propane conversion kit from a third-party supplier, Laars stepped in and delivered the component within days. Anthony Kiser received a brand-new replacement boiler at no cost after a manufacturing defect was identified, with installation expenses covered. These accounts illustrate how the manufacturer supports both end-use customers and the contractors who install their equipment.
