When your furnace stops working during a North Carolina cold snap, your home gets uncomfortable fast — and a broken heater at night can go from inconvenient to dangerous in a matter of hours. CR Weavers Heating and Cooling provides fast, honest furnace repair for homeowners throughout Kannapolis, Concord, Charlotte, and the surrounding area. We service all major brands of gas and electric furnaces including Carrier, Lennox, Goodman, Trane, Rheem, and York.

We diagnose the real problem, explain it in plain English, and give you an upfront price before we start any work. No pressure to replace when a repair will do — and no hidden charges after the job is done.

Our technicians are trained to diagnose and repair every component of your heating system. Common furnace repairs we handle for Kannapolis and Charlotte-area homeowners include:

Ignitor replacement — The most common gas furnace repair. When the ignitor fails, your furnace clicks on but never produces heat. Hot surface ignitors wear out over time and typically need replacement every 5-7 years.

Flame sensor cleaning and replacement — A dirty or failing flame sensor causes your furnace to light briefly then shut down within seconds. Often, a thorough cleaning restores normal operation. If the sensor is cracked or worn, we replace it.

Blower motor repair and replacement — The blower motor circulates heated air through your ductwork. A failing motor causes weak airflow, overheating, and unusual noises. We repair or replace motors on all brands.

Heat exchanger inspection — The heat exchanger is the most critical safety component in a gas furnace. Cracks can allow carbon monoxide to enter your home’s air supply. We inspect for cracks, corrosion, and stress fractures and recommend replacement when necessary.

Gas valve and gas pressure adjustment — If your furnace isn’t receiving the right amount of gas, it can’t heat properly. We test gas pressure, inspect the valve, and make adjustments or replacements as needed.

Thermocouple and limit switch replacement — These safety devices shut down your furnace when they detect problems. When they fail, your furnace may refuse to start or shut off prematurely. Both are straightforward repairs.

Control board diagnostics — The control board is the brain of your furnace. Electrical surges, age, and moisture can cause board failures. We diagnose whether the board can be repaired or needs replacement.

Draft inducer motor repair — The draft inducer removes combustion gases from the heat exchanger before the burners ignite. A failing inducer motor prevents your furnace from starting its ignition sequence.
