Our boiler installation service includes equipment sizing, piping layout, zone setup, and integration with radiant flooring or baseboard heat. Whether it’s gas-fired, electric, or combi-style, we’ll get your new boiler up and running with precision and care.
Boiler Repair
Boiler acting up? Don’t wait. If you’re dealing with inconsistent heat, unusual noises, low water pressure, or a complete shutdown, AON Heating & Cooling will diagnose the problem and provide fast, lasting repairs. We’re experienced with cast iron, steel, and condensing boilers—and we carry the parts needed to solve most issues in a single visit.
Boiler Maintenance & Tune-Ups
Preventative boiler maintenance is essential for long-term efficiency and safety. Our seasonal service includes pressure checks, expansion tank inspection, leak detection, burner cleaning, zone valve testing, and flushing if needed. A properly maintained boiler runs quieter, heats more evenly, and costs less to operate.
Why Boilers Still Matter in Chicagoland
Boilers remain one of the most efficient, comfortable heating options for many homes and buildings throughout Northern Illinois. Hydronic systems deliver steady, even heat without blowing dry air, and they’re especially useful in older homes where ductwork may be limited or nonexistent.
That said, proper installation and maintenance are key to getting the most from your boiler system. At AON Heating & Cooling, we bring the experience, attention to detail, and follow-through needed to keep your system running right—even through the worst winter storms.
Benefits of a well-installed and properly maintained boiler system include:
- Quiet, consistent heat across all zones
- No forced air, dust, or allergens
- Energy efficiency and fuel savings
- Fewer breakdowns and long-term reliability
- Compatibility with radiant floor heating and baseboards
If your boiler is showing signs of wear, we’ll help you decide whether it can be repaired or if a replacement would be the better investment.
Common Boiler Problems We Fix
A boiler may seem like a “set it and forget it” system—but when things go wrong, they tend to escalate quickly. Here are some of the most frequent issues we handle:
- No heat or hot water: Often caused by failed thermostats, circulator pumps, or low pressure.
- Unusual banging or kettling noises: Typically due to scale buildup, trapped air, or overheating components.
- Water leaks: May indicate faulty seals, aging pipes, or internal corrosion.
- Uneven heating in zones: Could be due to failed zone valves, air in the system, or circulation problems.
- Low water pressure or frequent refilling: Often a sign of leaks, expansion tank problems, or pressure relief valve issues.
