We know most homeowners don’t care much about the technical details—you just want to know if we can fix it and how soon. But the details do matter because they impact the cost of your furnace repair and may reveal ways to prevent the same issue in the future, like keeping up with furnace maintenance. Here are some of the most common furnace repairs in Forest Park so you can feel prepared before your appointment:

Furnace Not Turning On

When your furnace won’t start at all, it usually means a problem with the thermostat, power supply, or ignition system. Sometimes it’s as simple as a tripped breaker or a dirty flame sensor, while other times the ignitor or control board has failed. Our technicians run full diagnostic tests to pinpoint the issue and get your system firing up again quickly.

Furnace Blowing Cold Air

If the fan runs but the air never warms up, the culprit could be a faulty ignitor, dirty burners, or a thermostat miscommunication. In gas furnaces, safety switches may shut down the burners if something’s wrong, leaving only the fan blowing. We’ll identify what’s blocking the heat cycle and restore proper operation so warm air flows again.

Furnace Making Loud Noises

Banging, clanging, rattling, or squealing noises are clear warning signs. These sounds can come from loose blower parts, a cracked heat exchanger, or a motor that’s wearing out. Ignoring the noises can lead to bigger (and more expensive) problems. Our team tracks down the source, replaces or tightens components, and makes sure your furnace runs smoothly and quietly.

Furnace Smells Bad

Strange odors can mean very different things. A burning smell may just be dust on the heat exchanger at the start of the season, but it could also point to an electrical issue. A musty smell suggests moisture or mold in the ducts. And if you ever smell gas, that’s an emergency—shut the furnace down and call us right away. We’ll make sure your system is safe and your home’s air is fresh.

Furnace Turns On and Off Repeatedly

If your furnace is short cycling—running for a few minutes, shutting off, then starting again—it’s wasting energy and straining parts. Causes include dirty filters, blocked vents, overheating, or even a system that’s too large for your home. We’ll diagnose the root problem, make repairs, and get your furnace back to running on a steady cycle.

Furnace Energy Bills Going Up

A sudden spike in your heating bill is often a sign your furnace isn’t running efficiently anymore. Worn parts, airflow restrictions, or dirty filters can force it to work harder and burn more fuel. We’ll clean, repair, and tune the unit to bring your bills back down—and let you know if a furnace replacement might be a smarter long-term solution.

Before calling for furnace repair in Forest Park, there are a few simple things you can check that might solve the problem without a furnace repair service visit. Some issues have quick fixes, and a little troubleshooting can save you time and money. Here are a few steps to try before reaching out to Hill-Air:

• Set the Thermostat Correctly: Make sure it’s switched to heat and set a few degrees higher than your current room temperature. Replace the batteries if the screen is blank.
• Replace the Air Filter: A clogged filter can block airflow and make the furnace shut down. If it looks dirty or hasn’t been changed in a while, swap it out.
• Check the Power Supply: Look at your breaker panel—if the furnace breaker is tripped, reset it once. Also, confirm the furnace switch near the unit is flipped on.
• Inspect the Pilot or Ignitor: If you have an older furnace, make sure the pilot light is still lit. On newer models, if the ignitor isn’t glowing, it may need service.
• Open All Vents: Walk through your home and confirm supply and return vents aren’t closed or blocked by furniture or rugs.

If these steps don’t solve the problem—or if you smell gas, hear loud banging, or suspect a carbon monoxide issue—turn the furnace off and call Hill-Air Heating & Air Conditioning right away. Our licensed technicians will handle it safely and get your heat back on.

We know the thought of a furnace replacement can make you fear the worst. The good news? Many issues can be repaired and get your system running reliably again. But there are times when a furnace repair isn’t the best long-term solution. In certain situations, a furnace replacement may be required—or simply the smarter choice. Here are a few examples:

Furnace Is Beyond Repair or Very Old

Every furnace has a lifespan, usually 15–20 years with good maintenance. Once it reaches that age, even well-cared-for systems begin to lose efficiency and reliability. If the heat exchanger or other major components fail, repair may not even be possible. At that point, furnace replacement is the only safe option to keep your home warm.

Constant Breakdowns and Frequent Repairs

If you’ve had to call for repairs two or three times in a single heating season, your furnace is sending a message. Small fixes add up quickly, and the cost of repeated service calls often outweighs the price of a new system. Instead of worrying about the next breakdown, replacement gives you dependable heat and peace of mind.

Expensive Furnace Parts Need Replacing

Some furnace parts are extremely costly to replace, like the control board or blower motor. If one of these fails—especially in an older system—the repair bill can run so high that it makes more sense to invest in a new furnace. With a replacement, you’re putting that money toward a system that’s efficient, reliable, and covered by a new warranty.

If your furnace has already needed repairs this season, chances are it won’t be the last time unless the system gets more consistent care. Annual tune-ups catch those little problems early, clean away the dirt and wear that cause breakdowns, and keep everything running efficiently. In fact, studies show that regular maintenance can cut repair calls by up to 95% and lower energy use by as much as 30%. A single service visit now can save you from multiple repairs later.
