Common Heating System Issues
During cold winter months along the Delmarva Peninsula, a functioning furnace is essential. If your heating system isn’t performing optimally, check these potential problems:
- Thermostat Settings: Verify your thermostat is set to “heat” mode and the temperature setting exceeds the current room temperature. Replace batteries if applicable.
- Air Filter Inspection: A clogged filter restricts airflow and reduces efficiency. Replace filters every 1-3 months depending on usage and household conditions.
- Circuit Breaker: Check your electrical panel to ensure the furnace breaker hasn’t tripped.
- Gas Supply: For gas furnaces, confirm the gas valve is in the “on” position and pilot light is lit.
Air Conditioning Troubleshooting Tips
When summer heat arrives in Rehoboth Beach and surrounding areas, AC problems require immediate attention. Before calling for AC repair, try these steps:
- Power Check: Ensure your outdoor unit receives power and the circuit breaker is active.
- Outdoor Unit Clearance: Remove debris, leaves, and vegetation within two feet of your condenser unit to maintain proper airflow.
- Refrigerant Lines: Inspect copper lines running to your outdoor unit for ice buildup, which may indicate refrigerant issues requiring professional service.
- Condensate Drain: A blocked drain line can cause water backup and system shutdown. Check for standing water near your indoor unit.
When to Call Professional HVAC Service
Some situations require immediate professional intervention from experienced technicians:
- Strange odors like burning plastic or gas
- Unusual noises including grinding, squealing, or banging sounds
- Complete system failure after basic troubleshooting
- Visible damage to equipment or wiring
- Carbon monoxide detector activation
- Frozen evaporator coils or refrigerant leaks
Preventative Maintenance Recommendations
Regular maintenance prevents many common HVAC problems. Schedule professional inspections twice annually—spring for cooling systems and fall for heating systems. Professional technicians perform comprehensive checks including:
- Electrical connection tightening and testing
- Lubrication of moving parts
- Condensate drain clearing
- Refrigerant level verification
- Thermostat calibration
- System efficiency testing

If your system exceeds 15 years old or requires frequent repairs, replacement may be more cost-effective than continued repairs. Modern systems offer superior energy efficiency, reducing monthly utility costs while improving indoor comfort throughout your Delmar or Salisbury home.
