Common Issues

Common Furnace Problems We Diagnose and Repair

Over our eight years repairing furnaces throughout Altoona, PA, we've encountered just about every problem that can affect residential heating systems.

Furnace Won't Start or Turn On

This is probably the most common service call we receive—the furnace simply won't start when the thermostat calls for heat.

Common Causes We Investigate:

  • Thermostat Issues - Dead batteries, incorrect settings, or faulty wiring prevent your furnace from receiving the signal to start
  • Tripped Circuit Breaker - Power interruptions may trip the furnace circuit breaker
  • Blown Fuse or Safety Switch - Modern furnaces include safety switches that shut down operation if problems are detected
  • Faulty Ignition System - Gas furnaces use electronic ignition or pilot lights; problems with either prevent startup

We start with simple possibilities—checking the thermostat, verifying power supply—before moving to complex diagnostics.

Furnace Runs But Produces No Heat

Maybe your furnace turns on but little or no heat comes from your registers.

What We Check:

  • Dirty Air Filter - Restricted airflow is the most common cause of reduced heat output
  • Burner Problems - Gas furnaces with dirty burners can't produce proper heat
  • Failed Heat Exchanger - Cracks reduce heating capacity and create safety concerns
  • Ductwork Leaks - Disconnected ducts waste heated air before it reaches living spaces
  • Oil Burner Issues - For oil-fired furnaces, nozzle clogs or air in fuel lines reduce heat output

We measure temperature rise across your heat exchanger to determine if the problem is heat production or distribution.

Strange Noises from Your Furnace

Unusual noises often indicate problems needing attention.

Concerning Sounds:

  • Loud Banging - Often indicates delayed ignition where gas builds up before igniting; needs immediate attention
  • High-Pitched Squealing - Usually a worn blower motor belt or bearing
  • Rattling or Vibration - Loose panels, mounting hardware, or failing inducer motor
  • Scraping Metal Sounds - May indicate failing blower motor bearing
  • Rumbling After Burners Shut Off - Can indicate dirty burner or cracked heat exchanger

Strange sounds provide early warning before complete failure. Addressing these issues prevents more expensive breakdowns.

Oil Furnace-Specific Problems

Oil-fired furnaces have unique components requiring specialized knowledge.

Common Oil Furnace Issues:

  • Clogged Oil Filter or Nozzle - Sediment in fuel oil can clog filters and nozzles
  • Oil Pump Failure - The pump delivering fuel to the burner can wear out
  • Sooty Combustion - Improper air-to-fuel ratio creates excessive soot
  • Primary Control Issues - Safety controls can fail, preventing burner operation
  • Fuel Line Problems - Leaks or air infiltration cause operational problems

Oil heating systems require more regular maintenance than gas furnaces. Check out our furnace maintenance services for preventive care.

Cost & Recommendations

The cost for parts and labor, and whether repair makes sense

You'll never feel pressured or confused about what your furnace needs. Our technicians carry common parts, meaning most repairs are completed during the initial visit.

Important Decision

Repair vs. Replacement: Making the Right Decision

One of the most important questions we help homeowners answer is whether repairing their furnace makes sense or if replacement would be smarter.

When Repair Makes Sense

  • Your furnace is less than 12 years old - Furnaces in their first decade usually have plenty of life remaining
  • Repair cost is less than one-third of replacement - Common industry guideline
  • This is the first major repair - One repair during a furnace's lifespan is normal
  • The rest of the system is in good condition - If only one component failed

When Replacement Makes More Sense

Replacement often provides better value when:

  • schedule

    Your furnace is 15+ years old - Approaching end of typical 15-20 year lifespan

  • build

    You're facing major repairs - Major component failures (like a heat exchanger) can be costly and often make replacement the better value

  • repeat

    You've had multiple repairs recently - Indicates declining reliability

  • trending_up

    Your heating bills keep increasing - Older furnaces lose efficiency

  • thermostat

    Your comfort has declined - Uneven heating won't improve with repairs

Our Honest Assessment

We'll never pressure you toward unnecessary replacement, but we also won't recommend pouring money into a furnace on its last legs. Our eight years serving Altoona, PA homeowners have built a reputation for honest advice.

FAQs

Frequently Asked Questions About Furnace Repair

Our response time depends on current service demand and urgency. For true emergencies—no heat during extreme cold—we prioritize service and typically respond within a few hours. Non-emergency repairs are usually scheduled within 24-48 hours. Based on our eight years serving Altoona, PA, we've built capacity to handle typical winter demand. Call 814-515-6715 immediately if you're experiencing a heating emergency.

Repair costs vary depending on the issue, your furnace type, and the parts required. Minor fixes may be quick and straightforward, while major component replacements can be more involved. After we diagnose the problem, we explain what’s wrong and provide clear, upfront pricing before any work begins—so you’ll know the full cost and options before deciding to move forward.

While we specialize in Armstrong furnaces as an authorized dealer, we service all major brands including Carrier, Bryant, Trane, Lennox, Goodman, Rheem, and York. We also have extensive experience with oil-fired furnaces from various manufacturers. Our technicians receive ongoing training on multiple equipment types.

Generally, if your furnace is less than 12 years old and repair cost is less than one-third the cost of replacement, repair makes good sense. For furnaces 15+ years old facing major repairs, replacement often provides better long-term value. We assess your specific situation and provide honest recommendations. Our reputation is built on trustworthy advice, not pushing unnecessary replacements.

Furnaces often fail at night because that's when they work hardest. Altoona's coldest temperatures occur during overnight hours, demanding maximum output. Sustained high demand can cause a marginal component to finally fail. This is why we recommend annual maintenance—we identify components showing wear before they fail. Call 814-515-6715 immediately if your furnace quits overnight.

Based on our eight years of service experience, dirty air filters cause more problems than any other single issue. A dirty filter restricts airflow, causing the furnace to overheat and shut down. This appears as a "furnace won't run" problem but is actually a safety system protecting your equipment. Check your filter monthly during winter.

Absolutely—we have extensive experience repairing oil-fired furnaces throughout the Altoona area. Oil furnaces require different expertise than gas units, involving fuel delivery systems, burner nozzles, and combustion chambers. Our technicians are trained in oil furnace service including burner maintenance, combustion optimization, and fuel pump service.

We recommend annual professional maintenance for all furnaces, scheduled each fall before heating season. For oil-fired furnaces, annual service is particularly important due to combustion byproducts requiring regular cleaning. Visit our furnace maintenance page to learn more.

Loud banging sounds typically indicate delayed ignition—gas builds up before igniting, creating a small explosion. This requires immediate professional attention. Turn off your furnace and call us at 814-515-6715 right away. Don't continue operating a furnace making loud banging sounds.

This depends on your furnace's age and warranty terms. Armstrong furnaces typically include warranty coverage for parts (often 10 years), with heat exchangers frequently covered by limited lifetime warranties. We review your equipment's age and warranty status during service. For repairs covered under warranty, we handle the claim process.

While homeowners can handle basic tasks like changing filters, most furnace repairs require professional expertise, specialized tools, and safety knowledge. Furnaces involve high voltages, combustible gases, and potentially dangerous combustion byproducts. DIY repairs often create additional problems and void warranties. Our professional service restores heat quickly, safely, and correctly.

This short-cycling behavior typically indicates restricted airflow or a safety system shutting down the furnace. The most common cause is a dirty air filter restricting airflow, causing the heat exchanger to overheat. Start by checking your filter—if it's extremely dirty, replace it. If the problem persists, call 814-515-6715 for professional diagnosis.

Yes, we understand that heating emergencies don't follow a 9-to-5 schedule. We prioritize emergency calls, especially when vulnerable family members are affected by lack of heat. Call 814-515-6715 whenever you're experiencing a heating emergency, and we'll respond as quickly as possible.

Absolutely—this is one of the most important decisions oil furnace owners face. Oil furnaces often last 20-25 years with proper maintenance, so age alone doesn't determine the answer. We consider repair cost, furnace age and condition, whether you're facing repeated repairs, and your long-term plans. Our recommendation always prioritizes your best interests.
