Common Furnace Problems in Northern Virginia

Virginia winters can be unpredictable, with temperatures dropping into the teens and even single digits during cold snaps. That kind of cold puts significant stress on your heating system, and breakdowns often occur when you need heat the most. Here are the most common furnace issues we encounter in the Manassas area.

Ignition and Pilot Light Failures

Modern furnaces use electronic ignition systems, typically hot surface igniters or direct spark igniters, to light the burners. These components wear out over time and are one of the most common causes of heating failure. A faulty igniter means the furnace cannot light the gas, leaving you without heat. Our technicians carry common igniter replacements on their trucks for fast repair.

Blower Motor Issues

The blower motor circulates heated air through your ductwork and into your living spaces. When the blower motor fails or runs intermittently, you may notice weak airflow, strange noises, or no heat distribution at all. Blower motor capacitors are another frequent failure point that we replace regularly.

Thermostat Malfunctions

Sometimes the problem is not with the furnace itself but with the thermostat. A malfunctioning thermostat can cause your furnace to short cycle, fail to turn on, or run continuously without reaching the set temperature. We test and troubleshoot thermostats as part of every heating service call.

Dirty Flame Sensors

The flame sensor is a critical safety component that confirms the gas burners are lit. When it gets coated with residue, it cannot detect the flame and shuts the furnace down as a safety precaution. Cleaning or replacing a flame sensor is a quick, affordable fix that we perform frequently during the heating season.

Furnace Safety Is Our Priority

At HVAC of Virginia, we take furnace safety extremely seriously. Every heating repair we perform includes a carbon monoxide safety check at no extra charge. Carbon monoxide is an odorless, colorless gas produced by gas and oil furnaces, and a cracked heat exchanger or improper venting can allow it to enter your home.

Our technicians use professional-grade combustion analyzers to test CO levels and verify that your furnace is venting properly. If we detect any safety concerns, we will alert you immediately and explain your options. Your family’s safety always comes first.

When to Call for Heating Repair

Do not wait until your furnace completely stops working to call for repair. Early intervention can save you money and prevent a total breakdown during the coldest part of winter. Contact HVAC of Virginia if you notice your furnace is making unusual noises like banging, rattling, or screeching. Call us if your heating bills have increased significantly without a change in usage, if some rooms are much colder than others, if your furnace is cycling on and off frequently, or if you smell gas or notice a burning odor coming from your vents.

These symptoms often indicate problems that will only get worse with time. A quick service call now can prevent an expensive emergency repair later.
