About Ron Hammes Refrigeration
Ron Hammes Refrigeration has anchored itself in La Crosse since 1972, building a 4.9-star reputation across 211 reviews. The full-service contractor handles residential and commercial HVAC alongside specialized commercial refrigeration, serving La Crosse, Onalaska, West Salem, Holmen, Stoddard and surrounding communities. Their portfolio spans new installations, repairs, and ongoing maintenance for heating systems, cooling equipment, and walk-in refrigeration units.
What distinguishes Ron Hammes from typical HVAC contractors is their dual expertise in commercial refrigeration and custom sheet-metal fabrication. The company installs and services walk-in coolers for restaurants, schools, and businesses, a niche that demands specialized knowledge of refrigerant management and energy efficiency. Financing options remove barriers for customers facing unexpected system failures or planning upgrades.
Reviewers recount specific scenarios that illustrate their responsiveness. When guests were arriving at Wilson Schoolhouse Inn during a heat wave, David diagnosed the failing AC Sunday night and installed the replacement Monday despite rain. Another technician, Joe, provided same-day service to a customer in poor health, going beyond standard repairs to resolve the issue. One customer credits the team with a furnace that operated for 27 years.
What Customers Say
211 reviews yield a 4.9-star average, with customers repeatedly praising on-time arrivals, courteous technicians, and systems that last decades. Several reviewers note same-day emergency response, and multiple customers have remained with Ron Hammes for 20-plus years. The few lower ratings reference pricing concerns while positive reviews emphasize diagnostic skill and clean work sites.
