Every fall, Chicago homeowners face the same question: should I get my furnace tuned up before winter, and what’s it going to cost? The short answer is yes, you should — and the cost is much less than you might think, especially compared to the price of an emergency repair in January. Here’s a complete breakdown of what a furnace tune-up costs in Chicago, what it includes, and how to make sure you’re getting good value.

What Does a Furnace Tune-Up Cost in Chicago?

In the Chicago area, a standard furnace tune-up typically costs $75 to $150 for a one-time service call. Prices vary based on the company, the age and type of your furnace, and whether any minor adjustments or parts are needed during the visit.

At AMG HVAC Chicago, our standard furnace tune-up is $129. If you’re on our Residential Maintenance Agreement, that price drops to $90 — and you also get a spring AC tune-up included, for a total savings of $78 per year.

Be cautious of very cheap tune-up offers ($49 or less). Some HVAC companies use below-cost tune-up specials as a loss leader to get inside your home and upsell unnecessary repairs. A quality tune-up done right takes 60–90 minutes and involves a real inspection — not a 20-minute visual check.

What’s Included in a Furnace Tune-Up?

A thorough furnace tune-up should include all of the following:

Safety Checks

• Carbon monoxide test: The technician checks for CO leaks in the combustion chamber and heat exchanger. This is the most important safety check — a cracked heat exchanger can allow deadly CO to enter your living space.
• Flue and venting inspection: Checks for blockages, corrosion, or improper draft that could allow combustion gases to back up into the home.
• Gas pressure and combustion analysis: Ensures the furnace is burning fuel efficiently and completely.
• Safety control testing: Tests the limit switch, pressure switches, rollout switches, and other safety devices that shut the furnace down if something goes wrong.

Cleaning

• Burner cleaning: Removes dust, dirt, and debris from the burners for clean, efficient combustion.
• Heat exchanger inspection and cleaning: Checks for cracks (a serious safety issue) and removes scale buildup.
• Blower and motor cleaning: A dirty blower motor reduces airflow and efficiency significantly.
• Flame sensor cleaning: The flame sensor is a small rod that confirms the burner is lit. A dirty flame sensor is one of the most common causes of furnaces that won’t stay on — cleaning it takes 2 minutes and can prevent a service call mid-winter.
• Air filter check or replacement: Some tune-ups include a new filter; others check the existing one and replace if needed (usually at extra cost).

Mechanical Inspection

• Check all electrical connections and tighten if needed
• Inspect and lubricate the blower motor (if applicable)
• Check the inducer motor and draft blower operation
• Inspect the igniter (hot surface igniter or spark igniter) and replace if needed
• Check the condensate drain (on high-efficiency furnaces) for blockages
• Test thermostat calibration and operation
• Measure temperature rise across the heat exchanger

Why Annual Furnace Maintenance Pays for Itself

A $129 tune-up might seem like an expense you can skip — but consider the math. According to the U.S. Department of Energy, a well-maintained furnace uses 10–15% less energy than a neglected one. On a typical Chicago gas bill, that can save $50–$100 per year just in fuel costs. Add in the avoided repair costs (a service call in mid-January typically starts at $150+ just to show up), and the tune-up pays for itself easily.

More importantly, the safety checks protect your family. Carbon monoxide leaks from cracked heat exchangers are silent and deadly — a fall tune-up is the best way to catch this before it becomes a problem.

When Is the Best Time to Schedule a Furnace Tune-Up in Chicago?

The best time is September or October — before the heating season begins and before every HVAC company in Chicago is slammed with no-heat calls. Benefits of scheduling early in fall:

• More scheduling flexibility — you can pick a convenient time
• If a part needs to be ordered, there’s time to get it before cold weather hits
• Some companies offer early-season discounts

You can also schedule in November or even December, but expect tighter availability as the season heats up. If your furnace hasn’t been tuned up in 2+ years, schedule it now regardless of the time of year — don’t wait.

How Often Do You Need a Furnace Tune-Up?

Most manufacturers and HVAC professionals recommend once per year, typically in the fall before the heating season. This is especially important if your furnace is:

• More than 5–10 years old
• Running for the first time after sitting idle all summer
• Under warranty (many furnace warranties require annual maintenance to remain valid)

If you have a high-efficiency furnace (90%+ AFUE), the annual maintenance is even more important — the secondary heat exchanger and condensate system on these units require specific checks that can only be done by an HVAC technician.

What a Furnace Tune-Up Does NOT Include

A tune-up is a maintenance service — not a repair. If the technician finds a faulty part (a bad igniter, a failing inducer motor, a cracked heat exchanger), that repair is quoted separately. Before agreeing to any repair work, make sure you understand what’s broken, why it needs to be fixed, and what the total cost will be. A reputable company will show you the problem and give you a written estimate before starting any repairs.

The AMG HVAC Maintenance Agreement: Get More for Less

Instead of paying for furnace and AC tune-ups separately each year, our Residential Maintenance Agreement bundles both visits into one affordable annual fee. Agreement members also receive priority scheduling (you go to the front of the line during busy seasons), discounted diagnostic fees, and discounted parts on any repairs needed during the year.

It’s the smartest way to maintain your HVAC system and protect your home comfort investment — especially in a city with weather extremes as demanding as Chicago’s.

If a tune-up reveals your furnace has serious issues, you may need to consider replacement instead. See our complete guide on when to replace your furnace in Chicago for a full cost-benefit analysis.

Chicago winters are tough on every heating system — but boilers take a special kind of beating. If you heat your home with a boiler and something goes wrong in January, you need answers fast. This guide covers everything Chicago homeowners need to know about boiler repair: common problems, what repairs cost, and when to call a pro.

How Boilers Work (And Why They’re Common in Chicago)

Boilers are especially common in older Chicago homes — two-flats, greystones, bungalows, and coach houses built between 1900 and 1970 were typically heated with steam or hot water radiators powered by a boiler in the basement. Unlike forced-air furnaces, boilers heat water and circulate it through pipes and radiators throughout the home. Many Chicago homeowners love boilers for their even, comfortable heat — there’s no blowing dust or dry air, just steady warmth radiating from the cast-iron registers in each room.

At AMG HVAC Chicago, we service and repair boilers throughout the South Side, South Suburbs, West Side, and surrounding neighborhoods. Call us at (773) 562-6632 any time — we’re available 24/7 for emergency boiler repairs.

Common Boiler Problems in Chicago Homes

No Heat or Weak Heat

This is the most common complaint. If your boiler is running but the radiators aren’t getting hot — or only some rooms are heating — the issue is usually one of the following: a faulty circulator pump, air trapped in the system, a zone valve that’s stuck closed, or a low water pressure condition. A technician can diagnose and fix most of these in a single visit.

Boiler Leaking Water

Water pooling around the base of your boiler is never a good sign. Leaks can come from a failing pressure relief valve, corroded pipes or fittings, a cracked heat exchanger, or a pump seal failure. Small leaks can turn into big problems fast — especially in finished basements. Don’t wait on this one.

Pilot Light Won’t Stay Lit / Burner Won’t Fire

If your boiler has a standing pilot light that keeps going out, the thermocouple is usually the culprit — it’s a cheap part that’s easy to replace. On newer boilers with electronic ignition, a dirty flame sensor or failed ignition board may be to blame. Either way, no burner means no heat.

Boiler Making Strange Noises

Banging, clanking, whistling, or gurgling sounds from your boiler or pipes are signs something is off. Banging (“kettling”) is usually caused by limescale buildup on the heat exchanger or low water flow. Gurgling suggests air in the system. These noises should be investigated before they turn into a full breakdown.

Radiators Not Heating Evenly

If some rooms are hot and others stay cold, your system likely needs to be balanced. Air can also get trapped in individual radiators — bleeding the radiators (releasing the trapped air through the bleed valve) often fixes this immediately. It’s a simple DIY task, but if the problem persists, you may have a more serious circulation issue.

Pressure Problems

Both steam and hot water boilers operate within specific pressure ranges. Too low and the system won’t circulate properly. Too high and the pressure relief valve will vent — which is actually a safety feature working correctly, but it signals an underlying problem that needs attention. Check your boiler’s pressure gauge — normal operating pressure for hot water boilers is typically 12–15 PSI cold.

Boiler Repair Costs in Chicago

Boiler repair costs vary widely depending on what’s wrong. Here’s a general range to help you plan:

• Thermocouple replacement: $75–$150
• Circulator pump replacement: $250–$600
• Zone valve replacement: $150–$350 per zone
• Pressure relief valve: $150–$300
• Boiler bleeding and flush: $100–$200
• Heat exchanger replacement: $500–$1,500+ (sometimes it makes more sense to replace the boiler)
• Ignition board / control board: $300–$700

Labor rates in Chicago typically run $90–$150/hour for HVAC work. Emergency after-hours service will cost more. At AMG HVAC, we give you a clear estimate before any work begins — no surprises on the invoice.

Boiler Repair vs. Boiler Replacement: How to Decide

The general rule of thumb in the HVAC industry is the “Rule of 5,000.” Multiply your boiler’s age by the estimated repair cost. If the result exceeds $5,000, replacement is probably the smarter financial move. For example, a 20-year-old boiler needing a $350 repair: 20 × 350 = $7,000 — replacement makes sense. A 10-year-old boiler needing the same repair: 10 × 350 = $3,500 — repair it.

You should also consider replacing your boiler if:

• It’s more than 20–25 years old
• It needs repairs costing more than 50% of replacement cost
• Your heating bills have been creeping up year after year
• You’ve had multiple breakdowns in the last few seasons
• It’s an old atmospheric (non-condensing) boiler that can be replaced with a high-efficiency model

Modern high-efficiency boilers (like Navien, Weil-McLain, or Burnham) can achieve 95% AFUE efficiency vs. 70–80% for older models — which means real savings on your gas bill every winter.

Emergency Boiler Repair in Chicago

When your boiler goes out in the middle of a Chicago winter, it’s an emergency — especially if you have elderly family members, young children, or pets in the home. AMG HVAC offers 24/7 emergency heating service throughout Chicago and the South Suburbs. We dispatch quickly and carry common replacement parts on our trucks so we can fix most problems in a single visit.

Boiler Maintenance: Preventing Problems Before They Start

The best way to avoid an expensive emergency repair is a yearly boiler tune-up before the heating season starts — ideally in September or October. During a professional boiler maintenance visit, a technician will:

• Inspect all burners and clean the combustion chamber
• Check and test the pressure relief valve
• Inspect all pipes, fittings, and connections for leaks
• Test and calibrate the thermostat
• Check water pressure and top off if needed
• Bleed radiators and check for air in the system
• Inspect the flue and venting for proper draft
• Check heat exchanger integrity for carbon monoxide safety

Our AMG HVAC Maintenance Agreement covers your annual boiler tune-up along with a spring AC tune-up for one low yearly rate. It’s the most cost-effective way to keep your Chicago home comfortable and your heating system reliable year-round.
