Furnace Repair in Philadelphia & Bucks County
A furnace that quits on a January night is not a maintenance item, it is an emergency. Shepherd HVAC answers the phone 24 hours a day from our shop in Huntingdon Valley and gets a licensed technician to your door with the parts most no-heat calls actually need.
We diagnose before we quote. Ignition sequence, flame sensing, gas pressure, heat exchanger condition, limit switches, and blower operation all get checked so the repair addresses the real failure rather than the first symptom.

What to Watch For
Common Signs You Need Furnace Repair
Most furnaces give plenty of warning before a total failure. Any of the following is worth a service call before the next cold snap.
The furnace short cycles
Starting and stopping every few minutes usually means a limit switch is tripping from restricted airflow or a failing flame sensor.
Cold air from the vents
The blower is running while the burners are not, often due to ignition failure or a gas valve problem.
Yellow burner flame instead of blue
A sign of incomplete combustion. Stop using the system and call us — this can involve carbon monoxide.
Banging or booming at startup
Delayed ignition allows gas to accumulate before it lights, which damages the heat exchanger over time.
The blower never shuts off
A stuck fan limit control or wiring fault that wastes energy and wears out the motor.
A carbon monoxide alarm
Leave the house first, then call us. Cracked heat exchangers and blocked flues are both serious and both fixable.
How It Works
Our Furnace Repair Process
- 1
Priority no-heat dispatch
No-heat calls move to the front of the schedule year-round, and we run genuine 24/7 emergency service for households without heat.
- 2
Combustion and safety inspection
Beyond making the furnace run again, we verify draft, inspect the heat exchanger, and test for CO so the repair leaves the system safe as well as functional.
- 3
Flat written price
You approve the price before we start. If the furnace is old enough that repair money is better spent on replacement, we say so plainly and give you both numbers.
- 4
Repair, test, and document
We complete the repair, run a full heat cycle, record temperature rise and gas pressure, and leave you the readings.
Pricing
What Affects the Cost
Furnace repair costs range from routine to significant depending on which component failed and how the system was installed.
The failed part
Flame sensors and igniters are inexpensive; inducer motors, control boards, and heat exchangers are not.
Furnace age and parts availability
Discontinued parts on older equipment take longer to source and cost more.
Emergency vs. scheduled
Overnight and holiday calls are priced differently than daytime appointments.
Access
Tight crawlspaces and attic installations add labor time.
Related deferred issues
A failed part caused by a dirty filter or blocked flue means correcting the underlying cause too.
