When your home’s heater starts to underperform—blowing cool air, making strange noises, or causing your energy bills to skyrocket—it can be hard to tell whether it needs a simple fix or a full replacement.
Homeowners in the Kansas City area often ask us:
“Should I repair my furnace, or is it time for a new heating system?”
This guide will help you answer that question with confidence. We’ll walk you through the signs of a struggling heater, how to diagnose common issues, when furnace repair or boiler repair makes sense, and what to do if you need a heater replacement.
How to Know If Your Heater is Struggling
Your heater may still be running—but that doesn’t mean it’s running well. These warning signs typically mean your heating system is working harder than it should, and something needs attention:
- Uneven temperatures or cold spots in the house
- Frequent cycling on and off
- Unusual sounds (clanking, banging, whistling)
- Higher-than-usual energy bills
- Strange smells (burning, musty odors)
- The system struggles to reach or hold your thermostat setting
If you’re noticing any of these, it’s time to dig deeper and figure out if you need a heating repair or full system replacement.
How to Diagnose a Struggling Heater
Before jumping to conclusions, take these steps to help diagnose the issue:
1. Check the Thermostat
Make sure the thermostat is set to “heat,” and the temperature is correct. Dead batteries or programming glitches can mimic system problems.
2. Inspect the Air Filter
A dirty filter can restrict airflow, causing overheating and shutdowns. Replace it if it’s clogged or more than a few months old.
3. Look at the Pilot Light or Igniter
For gas furnaces, a pilot light that’s out or a faulty igniter can stop the unit from turning on. Electric units may trip breakers instead.
4. Check for Airflow Issues
Blocked vents, closed dampers, or duct issues can cause cold spots and short cycling.
5. Call for a Professional Inspection
If none of these simple fixes work, call Swyft Property Care for a full furnace repair or hvac repair diagnosis. Our technicians are trained to find and fix issues quickly, before they become emergencies.
Common Heater Problems (and Whether to Repair or Replace)
Here are some of the most frequent heating issues homeowners face—and our guidance on whether it’s better to repair or replace:
Repair Your Furnace If:
- Thermostat malfunction: A simple thermostat replacement solves this.
- Clogged filter or dirty blower motor: Routine HVAC maintenance can fix this.
- Pilot light or ignition control problems: Usually a minor repair.
- Blower fan issues: These can be repaired, especially on newer units.
- Wiring or electrical problems: Often repairable, unless systemic.
Replace Your Heater If:
- Cracked heat exchanger: This is a serious safety hazard and a common reason to replace a furnace.
- Frequent breakdowns: If you’ve needed heating repair more than twice in the past year, it’s time to upgrade.
- Age over 10 years: Most heating systems start to decline around this age, and parts can be hard to find.
- Inefficient performance: If your bills are rising and comfort is dropping, an older unit might not be worth saving.
Furnace Repair vs. Boiler Repair: What’s the Difference?
Not all heating systems are created equal. Here’s how to spot problems specific to your system type:
Furnace Repair
Gas or electric furnaces use forced air. Common issues include:
- Dirty flame sensors
- Burnt-out blower motors
- Ignition problems
These are usually repairable unless the unit is very old or has a cracked exchanger.
Boiler Repair
Boilers use hot water or steam. Signs of boiler trouble include:
- Leaks or puddles around the unit
- Radiators not heating
- Kettling (bubbling or banging noises)
Boiler repair is often possible if caught early. But older models with corrosion or failed pumps might be better to replace.
When to Replace: 5 Signs It’s Time
Still not sure? Here’s a quick decision guide to help you know when it’s best to replace:
- Your system is 10+ years old
Most systems start to fail mechanically or lose efficiency after this point. - Repairs cost more than 50% of a new unit
This is a good rule of thumb. If repairs are adding up, replacement pays off long-term. - You’re noticing constant issues
If you’re calling for heater repair multiple times a year, the system is on its last leg. - Your energy bills are getting higher
Older systems lose efficiency fast. Replacing can cut your heating costs by 20% or more. - Your home isn’t staying comfortable
No matter how often you tweak the thermostat, some rooms just won’t heat. This points to a failing heating system.
