- Visual inspection: cabinet, filters, access panels, and external flue or vent.
- Safety and combustion checks: pilot or ignition, flame pattern, gas pressure (for gas systems), and CO monitoring.
- Mechanical inspection and cleaning: burners, heat exchanger inspection for cracks or corrosion, blower cleaning, and filter change if needed.
- Performance test: start-up sequences, thermostat calibration, temperature rise check, and cycle efficiency.

Common furnace problems in Oyster Bay and how they are solved
- No heat or intermittent heat: often caused by failed ignition systems, clogged filters, or thermostat issues; solved by replacing ignitors, cleaning filters, or recalibrating controls.
- Short cycling: usually due to blocked airflow, dirty heat exchanger, or oversized unit—resolved through airflow balancing, cleaning, or system replacement evaluation.
- Pilot outage or ignition failure: replaced sensors/ignitors and safety checks on gas valves.
- Corrosion and vent deterioration: coastal salt accelerates rust; assessing and replacing corroded vents or caps prevents hazardous flue issues.
- Oil-system specific problems: burner nozzle wear, fuel filter clogs, and tank inspection; resolved through cleanings, nozzle replacement, and combustion tuning.
Safety, efficiency, and warranties
Safety is the top priority. A thorough combustion analysis and vent inspection reduce the risk of carbon monoxide. Efficiency improvements from regular maintenance and timely repairs lower fuel use and extend equipment life. Manufacturer warranties vary by brand and model; workmanship guarantees commonly cover labor for a defined period. Keep service records to support warranty claims and to show proper care for resale.
How furnace installation, repair, or an estimate typically works
- Initial contact: provide system type (gas, oil, model year), symptoms, and home details.
- Onsite inspection: a technician evaluates system condition, fuel lines, ductwork, and required permits.
- Written estimate: detailed scope of work, parts and labor breakdown, options for upgrades (high-efficiency models, smart thermostats, zoning), and projected lead time.
- Scheduling and permitting: if a replacement or major repair is selected, permit submission and municipal inspections may be required in Oyster Bay and Nassau County.
- Work completion: final safety and performance verification with documentation of any warranties or maintenance plan enrollment.
Maintenance tips for Oyster Bay homeowners
