Common Problems That Require Heating Repair
Furnace Blowing Cold Air
Cold air from the vents can result from a failed igniter, dirty flame sensor, gas supply issue, overheating that triggers the limit switch, or a thermostat set to fan instead of auto. A technician can quickly isolate the cause during heating repair.
Heater Not Turning On
A system that will not start may have a tripped breaker, blown fuse, failed control board, faulty thermostat, or a safety switch that has shut it down. Many of these problems are resolved with straightforward heating repair.
Short Cycling
A furnace or heat pump that turns on and off every few minutes wastes energy and wears out components. Common causes include clogged filters, a dirty flame sensor, overheating, a faulty thermostat, or an oversized system.
Uneven Heating and Cold Rooms
Rooms that never warm up can point to duct leaks, blocked vents, a weak blower motor, or a system struggling with reduced capacity.
Strange Noises
Banging, squealing, rattling, or scraping sounds may indicate delayed ignition, worn blower bearings, a loose belt, or a failing inducer motor. These noises should be checked before they lead to bigger failures.
Heat Pump Frozen or Stuck in Defrost
It is normal for a heat pump to enter defrost mode in winter, but a unit encased in ice or stuck in defrost may have a failed defrost control, sensor, reversing valve, or refrigerant problem that requires heating repair.
Safety Warnings With Gas Heating
If You Smell Gas
If you smell gas, leave the home immediately, avoid using light switches or phones indoors, and call your gas utility or 911 from outside. Schedule heating repair only after the utility has made the area safe.
Carbon Monoxide Concerns
Headaches, dizziness, or nausea that improve when you leave the home, or an alarming CO detector, can indicate carbon monoxide exposure. Leave the home, call 911, and have the heating system inspected before using it again.
Cracked Heat Exchangers
A cracked heat exchanger can allow combustion gases to mix with household air. Our heating repair inspections include checking the heat exchanger when conditions warrant.

Our Heating Repair Process
Full System Inspection
Every heating repair visit includes a check of the thermostat, ignition system, burners, flame sensor, blower motor, electrical connections, filters, venting, and safety controls. For heat pumps, we also check refrigerant pressures, defrost operation, and the reversing valve.
Clear Explanation and Pricing
We explain what failed, why it failed, and what the heating repair will cost before work begins. If the system is older and facing a major failure, we outline repair and replacement options so you can decide.
Repair and Testing
After completing the heating repair, we run the system through full heating cycles, measure temperature rise, and verify safety controls are functioning correctly.
Emergency Commercial HVAC Service

Heating Components We Repair
Igniters and Flame Sensors
Hot surface igniters and flame sensors wear out or become dirty over time, preventing the burners from lighting or staying lit. These are among the most frequent heating repair needs.
Blower and Inducer Motors
The blower moves warm air through your ducts, while the inducer motor vents combustion gases. Failure of either motor can shut down the system.
Control Boards and Thermostats
Control boards manage the heating sequence, and thermostats tell the system when to run. Faulty controls cause erratic operation or no heat at all.
Gas Valves and Pressure Switches
Gas valves control fuel flow to the burners, and pressure switches confirm safe venting. Problems with either can stop the system from firing.
Heat Pump Components
Heat pump heating repair may involve defrost boards, reversing valves, capacitors, contactors, compressors, and refrigerant leaks.
Preventing Future Heating Repair Needs
Fall Maintenance
A tune-up before winter catches dirty flame sensors, worn igniters, weak motors, and venting problems before they cause a breakdown on a freezing night.
Regular Filter Changes
Clogged filters cause overheating and short cycling. Replacing filters every one to three months prevents many heating repair calls.
Clear Space Around Equipment
Keep the area around your furnace free of stored items, and keep outdoor heat pumps clear of snow, ice, and debris.
Frequently Asked Questions About Heating Repair in Upper Marlboro, MD
How much does heating repair cost in Upper Marlboro, MD?
Heating repair cost depends on the failed part and the labor required. Replacing a flame sensor or igniter costs far less than replacing a blower motor, control board, or heat exchanger. A diagnostic visit provides an exact price.
Why is my furnace blowing cold air?
A furnace may blow cold air because of a failed igniter, dirty flame sensor, gas supply problem, overheating that trips the limit switch, or a thermostat fan setting left on.
Why does my furnace keep shutting off?
Frequent shutoffs usually result from a clogged filter, dirty flame sensor, overheating, a faulty thermostat, or blocked venting. These issues can typically be resolved with heating repair.
Is it normal for my heat pump to blow cool air in winter?
Heat pump air feels cooler than furnace air, and brief cool air during defrost is normal. Continuous cold air may indicate a defrost, reversing valve, or refrigerant problem requiring heating repair.
What should I do if I smell gas near my furnace?
Leave the home immediately, avoid switches or open flames, and call your gas utility or 911 from outside. Do not attempt to operate the furnace until it has been inspected.
How long does heating repair take?
Most heating repair visits take one to three hours. Repairs requiring special-order parts may take longer.
Should I repair or replace my old furnace?
Repair usually makes sense for systems under about 15 years old with an isolated problem. For older furnaces with a cracked heat exchanger, frequent breakdowns, or high repair costs, replacement may be the better value.
Can a dirty filter cause my heater to stop working?
Yes. A clogged filter restricts airflow, causes the furnace to overheat, and can trigger safety shutoffs.
Why is my furnace making a loud banging noise?
Banging at startup often indicates delayed ignition caused by dirty burners. It can also come from expanding ductwork. Delayed ignition should be addressed promptly with heating repair.
How often should my heating system be serviced?
Heating systems should be serviced once a year, ideally in early fall before cold weather arrives.
Can I reset my furnace myself?
You can check the breaker, thermostat, and filter, and some furnaces have a reset button. Repeated resets without fixing the cause can mask a problem, so persistent issues should be inspected.
