Boilers offer unique advantages over forced-air systems, particularly in homes with existing radiators, baseboard heaters, or radiant floor systems. Unlike furnaces that move air, boilers use water or steam to distribute heat evenly, quietly, and efficiently.
For many homeowners in Barrington, IL, a boiler remains the ideal solution for whole-home comfort.
If your current system isn't keeping up or showing signs of age, it may be time for a boiler replacement. Here are the most common indicators:
RJ's can assess your current unit and determine whether repairs or full replacement will offer better long-term performance and value.
At RJ's, we install a variety of boiler types based on your home's layout, heating style, and energy goals.
We proudly install Burnham and Weil-McLain boilers—two of the industry's most trusted manufacturers for residential heating systems.
We tailor every project to your home's specific needs, ensuring maximum comfort and performance. Here's what to expect from a typical boiler installation or replacement in Barrington, IL:
We inspect your current system (if applicable), perform a heat load calculation, evaluate your home's layout, and recommend the best type and size of boiler for your property.
We walk you through available system options (standard vs. high-efficiency) and provide a detailed estimate including labor, equipment, accessories, and permit costs.
If replacing a unit, we carefully remove and dispose of your old boiler, update any outdated piping or flue connections, and prep the area for your new system.
We install your new system, ensure all connections are sealed and secure, and integrate it with your thermostats, zoning controls, or radiant flooring as needed.

Most boilers last between 15 to 30 years, depending on the type and maintenance history. If your unit is over 20 years old, frequently breaks down, or struggles to keep your home warm, it may be time for a replacement. Rising utility bills, corrosion on the unit, or hot and cold spots in your home are also signs that your boiler is losing efficiency.
We install several types of boilers based on your home and heating needs:
We offer top-rated brands like Burnham and Weil-McLain, and can help you determine the right system for your home's size and comfort preferences.
Condensing boilers are more efficient because they reclaim heat from exhaust gases, whereas conventional boilers vent that heat out of the flue. Condensing boilers can reach efficiency levels of 90–95% AFUE, making them a smart long-term investment for reducing energy bills in Barrington homes.
Yes—especially modern condensing boilers, which can be up to 30% more efficient than older systems. If you're replacing a 20+ year-old boiler, upgrading to a high-efficiency model could result in significant energy savings and qualify you for rebates and tax incentives.
Most residential boiler installations take one to two days, depending on the size of the system and whether any additional work (e.g., piping upgrades, flue changes, or zoning integration) is required. Our team works efficiently to minimize disruption and ensure a clean, code-compliant installation.
Boiler size depends on your home's square footage, insulation, number of zones, and heat loss calculations. RJ's will perform a load calculation and system assessment to ensure your new boiler is properly sized—preventing energy waste and ensuring even, consistent comfort.
Combi boilers are compact systems that provide both central heating and hot water without the need for a separate water heater or storage tank. They're ideal for smaller homes or townhomes where space is limited. If you have high hot water demand (multiple showers at once), a traditional system may be better suited.
Yes, but it requires significant changes. Boilers distribute heat via water, not air, so converting from a forced-air furnace to a hydronic system would involve installing radiators, baseboard heaters, or radiant floor tubing. It's a more involved project, but one that offers long-term comfort and efficiency.
Yes. RJ's offers flexible financing options to help homeowners in Barrington afford high-quality heating upgrades without a large upfront expense. We also help customers qualify for ComEd and Nicor Gas rebates when applicable.
Boilers require annual maintenance to stay efficient and safe. A professional tune-up should include:
Routine maintenance extends system life and keeps warranties valid.
Yes—most modern boilers are compatible with Wi-Fi-enabled smart thermostats, especially if zoning controls are in place. RJ's can install and configure thermostats that allow for programmable scheduling, zoning, and remote control, helping you manage comfort and efficiency with ease.
Zoning allows you to control the temperature in different areas of your home independently. This is done with either multiple thermostats, zone valves, or circulator pumps. It's ideal for larger or multi-story homes and can reduce energy waste by heating only the rooms you use.
We trust and install:
Each brand we offer is supported by strong warranties, proven performance, and excellent long-term value.
Yes. Many high-efficiency boilers qualify for local utility rebates, and certain models may also be eligible for federal tax credits under the Inflation Reduction Act. RJ's will help identify the incentives you're eligible for and assist with application documentation.
