Residential Heating Repair
Roxly diagnoses and repairs heating problems for homes throughout the Charlotte metro area, with findings and an estimate reviewed with you before any work begins.
Common heating problems
- The furnace or heat system won't turn on
- Cold air blowing from the vents instead of warm
- The system runs but the house never reaches the set temperature
- The furnace cycles on and off repeatedly
- A burning smell during the first runs of the season
- Loud banging, screeching, or rattling from the unit
- The pilot light won't stay lit on older gas furnaces
- Uneven heating between rooms
What's usually behind it
Common causes include a failed igniter or pilot assembly, a tripped flame sensor, a bad blower motor, a faulty thermostat, or a clogged filter restricting airflow.
Repair, not replace
Most 'no heat' calls trace to a single component — an igniter, flame sensor, or control board — that's a straightforward repair on an already-installed system. Service availability may vary by location, equipment type, brand, technician availability, licensing requirements, and the scope of the requested work. Contact Roxly Appliance & Refrigeration Repair to confirm service availability for your address and equipment.
Safe checks before you call
- Replace the air filter if it hasn't been changed recently.
- Confirm the thermostat is set to Heat and the setpoint is above room temperature.
- Check that the furnace's power switch (often near the unit, looks like a light switch) hasn't been bumped off.
Beyond these basics, leave refrigerant, gas, and internal electrical components to a technician.
Frequently asked questions
Why won't my furnace turn on at all?
Start with the thermostat setting, the power switch near the furnace, and the breaker. Beyond that it's typically an igniter, flame sensor, or control board fault that needs a technician.
Is a burning smell from my furnace dangerous?
A brief dusty smell on the season's first run is normal. A persistent or strong burning smell is not — turn the system off and call for service.
Do you replace furnaces?
No — Roxly repairs and maintains existing residential heating systems. New furnace installation or full replacement requires a licensed Heating Group contractor.
Why is heat uneven between rooms?
Uneven heating often points to blocked vents, a failing blower, or duct airflow issues rather than the furnace itself. A technician can trace where the airflow is being lost.
