Furnace Repair in Philadelphia, PA
Top-Rated Furnace Repair in Philadelphia
Most furnace failures aren’t random. They’re the result of a component wearing down, a filter that hasn’t been changed, or a small issue that went unaddressed long enough to become a larger one. Finding the root cause quickly and fixing it correctly the first time can mean the difference between one service call and three.
TotalCare Heating & Cooling has been repairing furnaces for Philadelphia, PA, homeowners for over 15 years. Give us a call today if your furnace isn’t heating efficiently or if you’re in need of emergency service.
Furnace Repairs We Handle
Gas and electric furnaces share some common failure points, but they’re different enough that diagnosis requires knowing the system. We assess the full unit before recommending any repairs.
Ignition System Repair
Ignition problems are among the most common furnace issues we see. On modern gas furnaces, a dirty or failing flame sensor is a frequent cause of short cycling: the furnace lights, the sensor fails to confirm the flame, and the system shuts down within seconds. We also service hot surface igniters, which crack and fail over time, and older standing pilot systems where the thermocouple may need replacement.
Heat Exchanger Inspection and Repair
A cracked heat exchanger is the most serious issue a gas furnace can develop. When the heat exchanger fails, combustion gases, including carbon monoxide, can enter the air circulating through your home. If a heat exchanger issue is suspected or confirmed, we’ll tell you clearly what we found and give you an honest assessment of whether repair is viable or whether the system needs to be replaced.
Blower Motor Repair and Replacement
The blower motor circulates heated air through the duct system. When it fails or starts to wear, you’ll notice weak airflow from the vents, longer run times, or the furnace running without distributing heat effectively. We assess the motor and replace it if needed, sizing the replacement correctly for the system.
Thermostat and Control Board Repair
Control board failures can present as a wide range of symptoms, including the furnace not starting, running continuously, or behaving erratically. Thermostat issues can mimic control board problems. We test both systematically before drawing any conclusions about what needs to be replaced.
Limit Switch Replacement
The limit switch shuts the furnace down when the heat exchanger temperature gets too high, which usually happens because of restricted airflow. If the limit switch is tripping repeatedly, there’s almost always an underlying cause, such as a clogged filter, a blocked vent, or a failing blower, that needs to be addressed alongside the switch itself.
Gas Valve Repair and Replacement
A faulty gas valve can prevent the furnace from firing or cause intermittent operation. Gas valve issues require careful diagnosis to distinguish from ignition and flame sensor problems that present similarly. We test the valve and associated components before recommending a replacement.
Ductwork Inspection and Sealing
A furnace that’s working correctly but losing output through leaking or disconnected ducts won’t heat the home effectively. If the equipment checks out but certain rooms are still cold or your system is running longer than expected, we inspect the ductwork for gaps and insulation problems.
Emergency Furnace Repair
We offer emergency repair service for furnaces that go down when you need them most. If your heat fails overnight or during a cold stretch, reach out and we’ll prioritize getting to you.
Signs Your Furnace Needs Repair
Furnaces rarely fail without warning. If you notice any of these signs, give us a call:
- The furnace isn’t heating the home: If the system is running but your home isn’t reaching temperature, something is wrong with the equipment or the distribution system.
- Short cycling: A furnace that turns on, runs for a short time, and shuts off before the house warms up is usually dealing with a limit switch issue, an ignition problem, or restricted airflow.
- Yellow or flickering flame: On a gas furnace, the burner flame should be steady and blue. A yellow or unsteady flame indicates incomplete combustion and warrants prompt attention.
- The furnace won’t turn on: This can range from a tripped circuit breaker or a thermostat issue to a failed control board or igniter. A diagnostic visit will identify which.
- Unusual sounds: Banging on startup often points to delayed ignition. Squealing suggests a blower motor bearing issue. Rattling during operation can mean a loose component in the cabinet or ductwork.
- A burning smell: Some burning odor on the first startup of the season is normal as dust burns off the heat exchanger. Persistent burning smells during operation should be investigated.
- Carbon monoxide detector alerts: Evacuate and call for emergency service before re-entering the home.

Frequently Asked Questions (FAQs)
Age and the nature of the problem are the main factors. A furnace under 15 years old with a component failure, such as an igniter, a flame sensor, or a blower motor, is generally worth repairing. One that’s older, has had multiple repairs in recent years, or has a compromised heat exchanger is often better replaced. We’ll assess the system and give you a straight answer.
Short cycling is most commonly caused by a dirty filter restricting airflow and causing the system to overheat, a dirty flame sensor failing to confirm the burner flame, or a limit switch tripping as a safety response to overheating. Less commonly, it can be a sizing issue, such as an oversized furnace that heats the space too fast and shuts off before the home reaches temperature. A diagnostic visit will identify which one you’re dealing with.
We prioritize emergency calls and offer after-hours service for situations that can’t wait. Response time depends on current demand and your location, but we work to get to emergency calls as quickly as possible. Calling directly rather than using the contact form will get you the fastest response.
