CO alarm sounding? If a CO alarm sounds or anyone feels sick, get everyone outside and call 911.
Don't add water to a hot, empty steam boiler, and don't open a pressure relief valve. Shut the boiler off at its switch and call a company.
Signs your boiler or radiators need attention
- One or more radiators stay cold, or heat only at the bottom
- Banging, knocking or hissing in the pipes
- A leak at a radiator valve or under the boiler
- The boiler's pressure gauge reads much higher or lower than usual
- A steam boiler losing water fast or shutting off on low water
- The boiler won't fire, or it lights and quits
Older Park Ridge homes and radiator heat
About half of Park Ridge homes were built before 1960, and about 16% before 1940 (ACS 2020–2024). Older homes may have boilers and radiators instead of a furnace. There is no count of how many Park Ridge homes still do, but the city's oldest blocks, and Chicago-area neighborhoods like Edison Park and Norwood Park, are where boilers are most likely.
Boiler work in Park Ridge, Illinois is heating work like any other. Park Ridge's permit fee schedule lists a permit for furnace and boiler replacement; your contractor confirms and pulls it with the City (847-318-5291). Nicor Gas serves Park Ridge and the nearby suburbs.

Steam vs. hot-water boilers
Both heat water in a boiler and send heat to radiators, but they work differently, and the repairs differ too.
Steam systems boil water and send steam up through the pipes. The steam gives off heat in the radiators, turns back into water and drains back to the boiler. A steam boiler usually runs at low pressure and has a glass sight tube showing the water level. Radiators often have an air vent on one end that lets air out as steam arrives. Pipes must slope so water can drain back; when they sag, water collects and the system can bang.
Hot-water (hydronic) systems keep the pipes full of water and use a circulating pump to move it through radiators or baseboards. They run at higher pressure, have an expansion tank, and collect air over time, which is why hot-water radiators have small bleed valves.
Steam repairs often involve water level, vents and pipe pitch; hot-water repairs, the pump, expansion tank and pressure.
Bleeding radiators
On a hot-water system, a radiator that is cool at the top and warm at the bottom usually has air trapped in it. Bleeding lets the air out:
Turn the heat down
Let the system cool so the water isn't scalding.
Open the bleed valve
Use a radiator key on the small valve at the top corner, with a rag or cup underneath.
Close it when water appears
Hissing air turns to a steady drip of water. Close the valve snugly.
Check the pressure
If the boiler gauge drops a lot after bleeding, call a company to check the fill.
Steam radiators don't bleed this way. If a steam radiator stays cold, its air vent may be stuck or the radiator may need re-pitching; leave that to a heating company. Step-by-step help is in how to bleed radiators in an older Park Ridge home.

Questions to ask each company
- Are you registered with the City of Park Ridge (or the village where I live) this year, and can I see a current certificate of insurance?
- Will I get a written estimate that lists the diagnosis, the parts and the labor before you start?
- If the job is over $1,000, will you give me a written contract and the pamphlet "Home Repair: Know Your Consumer Rights" first?
- Does this work need a permit, and will you pull it?
- What do the parts and labor warranties cover, for how long, and can I have the terms in writing?
- If a rebate applies, will you fill in the rebate paperwork or give me the model numbers and invoice I need?
- How many steam or hot-water boilers like mine have you worked on, and do you carry parts for older systems?
- If you recommend replacement, will the new boiler be sized for the radiators in the house?
In Illinois, a home repair contractor must give you a written contract before starting work over $1,000, plus the state pamphlet "Home Repair: Know Your Consumer Rights." Questions or problems: Illinois Attorney General, 1-800-386-5438. Small repairs under $500 may be outside the Act, so don't count on contract rights for a basic service call.
If your home has forced air instead, see furnace repair or furnace replacement. Companies also quote in Norridge & Harwood Heights, Niles and Skokie.
Boiler and radiator questions
How do I know if I have a steam or hot-water boiler?
Look at the boiler. A steam boiler usually has a glass sight tube showing the water level and a pressure gauge reading only a few pounds. A hot-water boiler usually has a circulating pump, an expansion tank and a gauge reading higher. Radiators with a small air vent sticking out of one end are often steam. If unsure, ask the company.
Should I bleed my radiators?
Bleeding applies to hot-water radiators. If one is cool at the top and warm at the bottom, trapped air is a likely cause. Open the small bleed valve with a radiator key until water appears, then close it. Steam radiators don't bleed this way; their air vents work on their own. See how to bleed radiators.
How much does boiler repair cost?
A published national estimate puts boiler repair at $150–$700 (HomeGuide). Radiator bleeding runs $100–$200 and a radiator leak $150–$600 (Angi, 2025). No verified Park Ridge price list exists. Quotes come from independent companies, not this site.
Is there a rebate for a new boiler in 2026?
Nicor Gas's 2026 program lists a $350 rebate for a boiler of 95% AFUE or higher and $500 for a qualifying combination boiler that also heats domestic water. Programs change, and eligibility isn't promised; check nicorgas.com/homerebates.
