RJS Heating and Cooling, Inc. has kept Roselle-area homes comfortable for more than six decades, having opened its doors in 1959. The company holds proper licensing for Cook and DuPage counties and currently maintains a 4.8-star average across 236 verified customer reviews. Technicians regularly serve homeowners in Roselle, Elk Grove Village, and Algonquin, responding to heating emergencies and planning scheduled equipment upgrades throughout these northeastern Illinois communities.
Unlike many contractors who limit their manufacturer relationships, RJS Heating and Cooling partners with Trane, Weil-McLain, Aprilaire, and Honeywell, giving customers flexibility in equipment Selection without forcing a single brand preference. The company publishes a $35 first-visit discount for new customers and emphasizes that annual maintenance visits protect equipment efficiency while reducing monthly energy costs. Their website explicitly promises that technician teams arrive on time, explain repair options clearly, and leave workspaces cleaner than they found them.
Customer reviews frequently mention owner Scott and technician Bob responding to same-day emergencies, including one instance where a heating system failed at minus-12 degrees Fahrenheit and help arrived within fifteen minutes. Another reviewer described a Saturday afternoon furnace breakdown that became a full replacement installed by the following Monday, with temporary heaters provided overnight. Reviewer Linda Morange noted that her installation team started exactly on schedule and answered every question during a furnace-and-AC replacement project.
What Customers Say
Every reviewer awarding 5 stars names specific technicians, Scott, Bob, or Jody, and describes concrete outcomes like same-day furnace replacements or post-installation workspace cleanup. Five of seven detailed reviews mention some form of emergency or urgent-service scenario, and reviewers consistently praise communication timing and technician professionalism over pricing mentions.
