Replacing filter

Check and Replace Filters

One of the most straightforward yet crucial steps in maintaining your heating system is regularly checking and replacing the air filters. Clean filters improve indoor air quality, reduce the strain on your system, and enhance overall efficiency. Dirty or clogged filters force your heating system to work harder, increasing energy bills and wear and tear.

How Often Should You Replace Filters?

Inspecting your filters every month, especially during peak usage in winter, is recommended. Replace them every 1-3 months, depending on the type of filter and how often your system runs. If you have pets or live in an area with high dust levels, consider replacing them more frequently to maintain optimal airflow.

Inspect and Clean the Furnace

A clean furnace operates more efficiently and safely. Dust, dirt, and other debris can accumulate inside the furnace, affecting its performance and posing potential safety hazards. Regular cleaning helps prevent these issues and ensures your system operates efficiently.

What to Look For During Inspection?

Check for visible signs of wear or damage, such as rust, soot, or debris buildup. Make sure the burner flames are blue, indicating proper combustion. If you notice yellow or orange flames, it could mean a problem requires professional attention.


Cleaning the furnace involves removing dust from the blower, fan blades, and other accessible components. While some homeowners can handle basic cleaning, scheduling a professional service for a more thorough inspection and cleaning is recommended.

Set Your Thermostat Correctly

ThermostatProper thermostat settings can significantly impact your heating system’s efficiency. A programmable thermostat allows you to automatically adjust the temperature based on your schedule, saving energy when you’re asleep or away from home.

Benefits of a Programmable Thermostat:

  • Energy Savings: Lowering the temperature by just a few degrees when you’re not home can reduce your energy bills without sacrificing comfort.
  • Consistent Warmth: A programmable thermostat helps maintain a consistent indoor temperature, ensuring your home stays cozy without constant adjustments.
Set your thermostat to lower temperatures at night or when the house is empty, and schedule it to warm up shortly before you wake up or return home. Read more about your thermostat in our blog, “Programming Your Thermostat: Finding the Optimal Heating Schedule for the Fall.”

Schedule Professional Maintenance

While DIY maintenance can help keep your heating system in check, a professional inspection is essential to ensure everything works correctly. A professional technician can perform safety checks and efficiency adjustments and identify potential issues before they turn into costly repairs.

Why Professional Maintenance Matters:

Heating System Maintenance
  • Safety Checks: Professionals check for gas leaks, carbon monoxide risks, and other safety concerns that could harm your home.
  • Efficiency Adjustments: Technicians calibrate your system for optimal performance, ensuring it runs efficiently and uses energy effectively.
  • Early Problem Detection: Regular maintenance helps catch minor issues before they become major problems, saving you money on repairs and avoiding inconvenient breakdowns.
Schedule a maintenance service before the peak winter season begins to ensure your heating system is ready to perform when needed.

Check for Air Leaks and Insulate

Air leaks in your home can force your heating system to work harder than necessary. Inspect windows, doors, and other areas where drafts may occur, and seal any gaps with weatherstripping or caulking.

Insulation Tips:

Proper insulation prevents heat loss and keeps your home warmer, reducing the workload on your heating system. Check the insulation in your attic, walls, and floors, and add more if necessary. Consider insulating window treatments or using draft stoppers to keep the cold air out.
