Inside the heating call

A furnace starts
in stages.

Explore a typical induced-draft gas furnace with hot-surface ignition. A stop along the way gives a technician a place to investigate. It does not identify a failed part by itself.

STEP 01 / 07

The thermostat asks for heat.

The control receives a heating request.

What a technician checks

Power, settings, wiring, and control response.

Report the displayed temperature, setpoint, and mode.

This is an explanation, not a startup or repair procedure. Equipment designs, timing, and safety checks vary. Controls can stop the process at more than one point. Keep covers in place and do not bypass a safety switch or repeatedly reset a fault.

The symptom is the starting point

A few seconds of flame?
There is more to check.

A flame-sensing issue is one possibility when a furnace lights and stops. Wiring, grounding, gas delivery, and combustion can cause similar behavior. We test before recommending a part.

The right checks for your equipment

Different systems.
Different repair paths.

A furnace and a heat pump do not make heat the same way. Tell us which equipment you have, or let us help identify it before planning the visit.

FUEL + POWER + AIRFLOW

Furnace repair

We follow the heating sequence and assess the cause of a failed start, shutdown, or comfort problem.

  • Ignition and flame-sensing concerns
  • Blower, controls, and electrical faults
  • Airflow and applicable fuel/venting checks

INDOOR + OUTDOOR

Heat pump repair

Heating depends on the outdoor unit, indoor airflow, controls, and any installed backup heat.

  • Poor heating or persistent icing
  • Electrical and defrost problems
  • Control and refrigerant-system diagnosis

TWO HEAT SOURCES

Dual-fuel repair

When a heat pump and furnace share the job, both systems and their changeover controls matter.

  • Identify which heat source is affected
  • Review thermostat and control settings
  • Assess the complete heating arrangement

Simple observations. Better information.

Before you call,
start with what you can see.

If there is no alarm, gas odor, smoke, or fire, these basic observations can make the first conversation more useful.

SETTINGS YOU CAN SEE

Read the thermostat.

Confirm the normal Heat setting and compare the setpoint with room temperature. Note fan mode and visible messages. Follow the owner instructions for battery care; leave wiring in place.

FILTERS + OPEN AIR PATHS

Look at the air path.

Check for furniture covering room vents. For an accessible homeowner-serviceable filter, follow the owner’s access and shutdown procedure and use the correct type. Leave burner and electrical compartments closed.

MESSAGES + WHAT CHANGED

Keep the useful clues.

Note when the issue began, affected rooms, recent service, and any power outage. Record messages visible on the outside. Do not restart the equipment just to recreate a sound or a fault.

Leave internal service to a qualified technician. Do not clean burner components, move gas valves, remove electrical covers, or bypass controls. A repeatedly tripping breaker should stay off for assessment. Turning power off does not make every internal repair safe.

From a symptom to a decision

Know what failed.
Know what it takes
to fix it.

We explain the diagnosis in plain language, discuss the proposed work, and give you a price before the repair begins. Ask about the parts, repair scope, applicable warranty, and any additional work that may be needed.

Start with the visit terms. Confirm diagnostic and after-hours charges when scheduling. A free estimate does not mean the service visit or diagnosis is free.
  1. 01

    Tell us what changed.

    Share the equipment type, symptom, service address, and how the home is affected. We confirm availability and visit charges.

  2. 02

    Test the cause.

    We assess the applicable controls, power, airflow, and heating components using the equipment’s requirements.

  3. 03

    Review the proposal.

    We explain the finding and proposed repair scope and price. You decide whether to approve the work.

  4. 04

    Check the result.

    After approved work, we check applicable operation and explain any remaining concerns or recommended follow-up.

A decision based on your system

Repair it?
Plan its replacement?

Start with the diagnosis, then compare the options. Age matters alongside condition, repair history, part availability, warranty coverage, and the cost of each path.

Consider the repair.

A defined fault in otherwise serviceable equipment may be a practical repair. Ask what the work resolves, what it does not address, and which parts or labor are covered.

A smaller part does not always mean a small job. Access, testing, and the cause of failure still matter.

Compare a replacement.

Repeated failures, major damage, difficult-to-source parts, or broader performance problems can make replacement worth evaluating. Compare complete written scopes and the needs of the home.

Call with your question

Who provides heating repair in Northern Virginia?

PRO Electric plus HVAC provides heating repair across Fairfax, Loudoun, Arlington, and Prince William counties, including Falls Church. Our team handles HVAC and related electrical needs under Virginia contractor license 2705181607. Call 703-225-8222 with your equipment type, symptoms, and service address.

What should I do if my heating stops working?

If there is a CO alarm, gas odor, smoke, or fire, leave and call 911 from outside. Otherwise, note the thermostat settings, room temperature, visible messages, and any power outage. Call to discuss the problem and current service availability. Keep equipment covers in place and avoid repeated resets.

Why is my furnace blowing cold or lukewarm air?

Possible causes include fan settings, a heating or ignition fault, restricted airflow, or a safety shutdown. The timing and whether the home reaches the thermostat setting help guide diagnosis. A heat pump can feel cooler at the vent than a furnace and needs a different assessment.

My furnace lights and then shuts off. Is it the flame sensor?

A flame-sensing problem is one possibility. Ignition, wiring, grounding, gas delivery, combustion, and other controls can produce similar behavior. A technician checks the operating sequence and readings before recommending cleaning or a replacement part. The symptom alone is not a diagnosis.

Should I clean the flame sensor myself?

Internal furnace work involves electrical, fuel, and combustion components. Have a qualified technician follow the equipment’s service procedure and verify operation afterward. Turning off a switch does not make every part of the job safe. Never bypass a flame sensor or another safety control.

What can I check without opening the furnace?

You can review normal thermostat settings, note a power outage, look for blocked room vents, and record messages visible on the exterior. Use the owner instructions for an accessible homeowner-serviceable filter or thermostat batteries. Do not open electrical or burner compartments, move gas valves, or repeatedly reset a breaker.

Does a pressure-switch code mean the switch is bad?

No. The code describes a condition the control detected. Venting, condensate, wiring, the inducer, the switch, or another issue may be involved, depending on the model. A technician checks the cause rather than replacing a switch based only on a code.

Can a heat pump blow cool air and still be working?

Yes. Supply air may feel cooler than furnace air, and a heat pump can change operation during defrost. Persistent loss of comfort, heavy ice that remains, or repeated abnormal operation warrants service. Tell us the room temperature, setpoint, and any thermostat message.

What should I do if the heating breaker keeps tripping?

Leave a repeatedly tripping circuit off and call for professional assessment. Do not keep resetting it or replace it with a larger breaker. The problem may be in the equipment, wiring, or circuit. If you see smoke or fire, leave and call 911 from outside.

How quickly can you repair my heat?

Call 703-225-8222 for current availability. Tell us if there is no heat, how cold the home is getting, and whether anyone needs prompt access to a warm location. Arrival and completion depend on scheduling, diagnosis, equipment condition, and parts availability. An online request does not confirm dispatch.

Will I know the repair cost before work starts?

We explain the diagnosed issue and proposed repair price before the repair begins. Ask about diagnostic, visit, or after-hours charges when scheduling. A free estimate does not mean that diagnosis or a service visit is free. Parts and scope affect the final proposal.

Should I repair or replace my heating system?

Consider the specific fault, equipment condition, repair history, part availability, warranty coverage, and the cost and scope of both options. Age is one factor, not an automatic replacement rule. We can explain the repair finding and discuss replacement when it is a reasonable option.

Why use one team for HVAC and electrical work?

Heating equipment depends on controls, power, motors, and wiring as well as airflow and, for fuel-burning systems, combustion and venting. PRO Electric plus HVAC can assess the heating system and related electrical needs together. The work required depends on the fault and service scope.

Does the symptom guide send a service request?

No. Your selections stay on the page. Copy your note for the service conversation, then call or use the request form. The guide does not diagnose the equipment, confirm safety, quote a price, or book an appointment. A team member confirms service availability and scope.
