COMMON SIGNS OF FURNACE PROBLEMS
Heating systems can develop issues over time, and not all problems result in an immediate breakdown. Sometimes, the warning signs are subtle. If you notice any of these issues, it’s time to call an HVAC expert:
- Persistent Odors – A temporary dust-burning smell is normal at the start of the season. However, if odors linger or worsen, it’s time for professional help.
- Loud Noises – Banging, rattling, or other odd sounds may indicate internal issues. Schedule an inspection to prevent further damage. Call 571.346.3940 for expert furnace repair in Reston or Herndon.
- Frequent Breakdowns – If you find yourself scheduling repairs often, your furnace may be wearing out. While maintenance is necessary, constant issues are a red flag.
- Rising Heating Bills – If your energy costs keep climbing despite normal usage, your furnace may be working inefficiently. A professional inspection can determine if repairs or a replacement are needed.
- Rust Buildup – Some rust is expected over time, but heavy corrosion on your furnace or vents can indicate dangerous venting problems. Addressing it quickly can prevent safety hazards.
- Short Cycling – If your furnace repeatedly turns on and off, an underlying malfunction is likely. Let our heating professionals diagnose and fix the issue.
- Difficulty Starting – Difficulty starting your furnace or clicking noises may indicate an impending failure. Call Dave’s Heating and Air Conditioning or schedule a service online.

TOP 5 CAUSES OF FURNACE FAILURE
Homeowners can avoid unnecessary repairs by understanding the most common furnace issues:
- Dirty Filters – A blocked filter reduces airflow, forcing your furnace to work harder. Change it regularly for better efficiency.
- Thermostat Malfunctions – If your furnace won’t turn on, check your thermostat settings and batteries. A faulty thermostat may need to be replaced.
- Ignition Problems – A broken ignitor or pilot light means no heat. Call 571.346.3940 for professional service.
- Exhaust Blower Failure – This component removes combustion gases. If it stops working, your furnace may cycle frequently or shut down completely. Regular inspections can help avoid this issue.
- Blower Motor Malfunction – The blower motor circulates warm air throughout your home. If it fails due to overheating or dust buildup, your furnace will run but won’t distribute heat. Keeping your ducts clean and scheduling regular tune-ups can extend its life.
- Heat Exchanger Damage – A cracked heat exchanger is a serious issue. It’s costly to replace, and excessive cycling can make the problem worse. Sometimes, a full furnace replacement is the better option.

Furnace smells in Reston may stem from a few different sources. Burning dust at startup, mold or mildew in the system, and electrical burning odors due to a short circuit* are common culprits. A rotten egg smell is often a sign of a gas leak*, and grime in the heat exchanger can also create unpleasant odors.
