Why is the furnace blowing cold air?
The blower can run before ignition finishes, or after a safety shutdown cuts the burner. Time how long the cold air lasts.

Furnace repair in Braddock Heights, MD
A furnace that starts and stops, blows cold air, or won't answer the thermostat is still telling you something. The timing and the sound are the clues - especially on a cold night up on the mountain, when the cottage-era houses up here give up their heat fast.
Check the thermostat, the filter, and the breaker once if it's safe to do so. Note the error light, the ignition sound, what the blower's doing, and any smell. Keep the burner cabinet closed.
What the symptom can mean

How the visit should go
We check power, airflow, and ignition first. Then flame sensing, controls, and safety switches. You'll hear what we found and how it explains what you're seeing.
Diagnosis first, then a written recommendation and your approval. After that comes the repair, and we test the system again before we call it done.
What to decide next
We'll repair a focused failure when the equipment's still serviceable. We talk replacement when failures keep repeating, parts aren't available, safety's a concern, or a major part's already gone.

Why does it short cycle?
Airflow, the thermostat, ignition, or a safety control can all create that pattern. The timing between starts tells us which.
What if I smell gas?
Leave the home. Call the gas utility or 911 from outside, not from the kitchen.
