Boiler Installation & Replacement in Chicago

🏗️ Boiler Installation and Replacement Services

We install and replace all types of residential and commercial boilers — hot water boilers, steam boilers, and modern high-efficiency condensing units. Whether you need a straight like-for-like replacement after a complete system failure, or you're upgrading from an old cast iron boiler to a modern condensing unit, we handle the full job from assessment through commissioning. We're experienced with Lochinvar systems, which are among the most efficient and well-engineered boilers on the market.

A proper installation isn't just swapping equipment. It involves correctly sizing the new system to your home or building's heat load, matching the distribution system — baseboard, radiators, or radiant — ensuring the venting meets code, and commissioning the controls correctly. Cutting corners on any of these leads to a system that underperforms, short-cycles, or fails early. We don't cut corners.

🔎 Choosing the Right Boiler for Your Home or Building

The right boiler depends on what's already in your home, how much heat you need, and what fuel you're working with. Hot water boilers — which circulate heated water through pipes to radiators or baseboard units — are the most common replacement scenario. If you have a steam system, the replacement options are different: you can swap for a new steam boiler and keep your existing radiators, or convert to hot water. Conversion is sometimes worth considering, but it's a bigger project and not always necessary.

Modern high-efficiency condensing boilers can achieve 90%+ AFUE ratings, which can meaningfully reduce your annual gas bill compared to an older 70–80% efficient system. The upfront cost is higher, but the payback period over 10–15 years is real. We'll walk you through the options — what level of efficiency makes sense for your home's heat load, what the install complexity looks like, and what realistic cost ranges are at different tiers. We're not here to push the most expensive unit if it doesn't fit your situation.

How much does a new boiler cost in Chicago?

Boiler replacement costs in the Chicago area depend on several factors: the type and size of boiler, fuel type, whether you're doing a like-for-like swap or changing system type, the complexity of the existing pipework, and whether permits are required. Residential hot water boiler replacements generally range from a few thousand dollars for a basic replacement to $8,000–$12,000+ for a large-capacity or high-efficiency commercial-grade system. We give you a fixed quote after assessing your specific situation — no surprises.

We provide options at different price points rather than a single take-it-or-leave-it quote. That might mean a standard boiler at the lower end, a high-efficiency unit in the middle, and a premium Lochinvar installation at the top — with honest commentary on what you get at each level. You choose based on your budget, your priorities, and how long you plan to stay in the property.
