Furnace Repair
Professional Heating Repair for Safe, Consistent Warmth
No Heat or Insufficient Heat
If your furnace runs but the house stays cold, the problem could be a faulty ignitor, gas valve, heat exchanger or blower motor issue.
Furnace Won't Start
Electrical problems, failed igniters, pilot issues or thermostat faults can all prevent a furnace from starting. We trace the exact cause.
Blowing Cold Air
A furnace blowing cold air usually indicates a flame sensor problem, overheating condition or delayed ignition that requires immediate attention.
Unusual Noises
Banging, rattling or squealing from a furnace are warning signs. Some indicate minor issues; others indicate serious mechanical problems.
Short Cycling
A furnace that turns on and off too quickly wastes fuel, stresses the system and can leave your home unevenly heated.
Carbon Monoxide Concerns
A cracked heat exchanger is a serious safety issue. If your CO detector triggers or you smell gas, call us immediately or call 911 first.

What We Inspect & Repair
Furnace Components We Service
🔥
Heat Exchanger
Cracks in the heat exchanger allow combustion gases — including carbon monoxide — to enter your living space. This is a safety-critical inspection on every furnace call.
⚡
Igniter & Flame Sensor
The two most common causes of a furnace that won't start. Often inexpensive to fix when caught early.
💨
Blower Motor
Moves heated air through your ducts. A failing blower causes uneven heating, weak airflow and higher energy use.
🎛️
Gas Valve & Burners
Dirty or misaligned burners cause incomplete combustion, carbon buildup and reduced efficiency.
🌡️
Thermostat & Controls
Sometimes the furnace is fine and the control system is the problem. We test both before recommending any part replacement.
🔌
Safety Switches
Limit switches and pressure switches protect your furnace from overheating. When they fail, the system shuts down repeatedly.

Frequently Asked Questions
Is it safe to run my furnace if it's making strange noises?
Not always. Some noises are minor, but banging or rattling can indicate serious mechanical problems. We recommend having it inspected before continued use.
How do I know if my furnace needs repair or replacement?
Age, repair cost, and performance are the key factors. We give you an honest assessment of both options without pressure.
Do you service gas and electric furnaces?
Yes. We service both gas and electric furnace systems for residential and select commercial properties.
What if my furnace breaks down in the middle of the night?
