Heating problems deserve a system-level diagnosis.
Central HVAC evaluates furnaces, gas and oil boilers, and the controls and distribution systems that affect comfort, reliability and safe operation. We focus on identifying the cause of a problem and explaining practical repair or replacement options.
Furnace or boiler not heating properly?
Tell us what your system is doing, where you're located and, if available, the equipment make, model and age. We'll review your request and discuss the next step.
Furnace repair and diagnostics
A furnace that will not start, blows cool air, runs continuously or cycles on and off may have an issue with ignition, controls, airflow, venting or other components. Central HVAC evaluates the system before recommending a repair.
- Ignition, burner and flame-sensing issues
- Thermostat, control and safety-switch troubleshooting
- Blower operation, filters and airflow restrictions
- Heating performance and operating checks
Gas and oil boiler service
Boiler problems can involve burner operation, combustion, water pressure, circulation, venting, controls or the heat-distribution system. We work with residential gas and oil boilers, including hot-water and steam heating systems.
- Boiler diagnostics and operating evaluation
- Hot-water circulation and heating-zone issues
- Steam-system performance and distribution concerns
- Controls, pressure and safety-related checks
Fall furnace inspections and heating tune-ups
Schedule a seasonal furnace inspection and tune-up before winter temperatures arrive. Central HVAC reviews heating operation and looks for developing issues that may affect comfort, reliability or safe operation. The specific checks depend on your equipment and its condition.
- Thermostat operation, heating controls and safety devices
- Burner, ignition and heating performance checks, as applicable
- Air filter condition, blower operation and airflow
- Accessible venting and condensate components, where applicable
Routine maintenance can identify concerns early, but it cannot guarantee that a system will not break down. Explore maintenance services →
Heating replacement and installation
When replacement makes more sense than repair, equipment selection should consider the home's heating needs and the existing ductwork or hot-water or steam distribution system. Central HVAC evaluates sizing, equipment compatibility, controls, venting and installation requirements rather than relying on equipment efficiency ratings alone.
We can also review heating and cooling compatibility when planning a combined system replacement.
