Furnace Repair
When the Heat Goes Out
A dead furnace on a January night in the DMV isn't something that can wait until next week. Ducco offers prompt furnace repair—same-day when possible—to get your home warm again.
Our technicians work on gas furnaces, heat pumps, and dual-fuel systems. We diagnose the actual problem, give you upfront pricing, and tell you honestly when a repair makes sense and when replacement is the smarter spend.
Common Furnace Problems We Repair
Our technicians diagnose and repair all types of furnace failures.
No Heat / Won't Ignite
Ignitor, pilot, and gas-valve diagnostics to get your heat back on.
Blower Motor Failures
Replacement of failed blower motors, capacitors, and belts to restore warm airflow through your home.
Short Cycling
A furnace that starts and stops repeatedly—often a flame sensor, clogged filter, or venting issue.
Dirty Flame Sensors
Cleaning or replacing flame sensors that shut the burner down seconds after ignition.
Thermostat & Control Problems
Troubleshooting thermostats, control boards, and wiring that keep the furnace from responding.
Venting & Safety Concerns
Inspection of heat exchangers and flue venting. If we find a safety problem, we show you and explain your options.
Signs You Need Furnace Repair
If you're experiencing any of these symptoms, it's time to schedule service.
Cold Air from Vents
The blower runs but the air never warms up—often an ignition or burner problem.
Furnace Won't Start
No response from the thermostat can point to power, control-board, or safety-switch issues.
Frequent On/Off Cycling
Short cycling wastes fuel and wears components out faster.
Burning or Musty Smells
Brief dust burn-off is normal at season start; persistent odors are not.
Yellow Burner Flame
A healthy gas flame burns blue. A yellow, flickering flame can indicate incomplete combustion.
Rising Heating Bills
Unexplained increases in heating costs point to declining efficiency.
