Heating Service and Furnace Maintenance

  1. Change air filters regularly: Clogged filters restrict airflow and increase energy consumption. Aim to replace them every three months or as recommended by the manufacturer.
  2. Keep the area around the furnace clear: Remove any combustible materials, such as boxes or rags, to prevent fire hazards and ensure proper airflow.
  3. Inspect the thermostat: Check that the thermostat is working correctly and set to the desired temperature. Replace batteries if needed.

Furnace Replacement

If your furnace is more than 15 years old or experiences frequent breakdowns, it may be time for a replacement. Here are some tips:

  • Research energy-efficient models: Look for furnaces with high AFUE (Annual Fuel Utilization Efficiency) ratings to save on energy costs.
  • Consider the size: Ensure the new furnace is appropriately sized for your home to avoid inefficient operation.
  • Hire a professional: While DIY installation is possible, it’s recommended to have a qualified HVAC technician handle the job to ensure proper installation and safety.

Heater Installation and Heating Repair

  1. Check for gas leaks: If you smell gas, turn off the gas supply and call a professional immediately.
  2. Inspect the pilot light: If the pilot light is out, follow the manufacturer’s instructions to relight it safely.
  3. Clean the burners: Dirty burners can cause inefficient combustion and safety hazards. Use a vacuum or compressed air to remove debris.
