Electric furnaces are common in many homes throughout Central Ohio, especially in homes without natural gas service. While electric furnaces are reliable and relatively simple systems, they can be expensive to operate during cold winters, especially if the home and HVAC system are not maintained properly. Fortunately, there are several ways homeowners can improve efficiency and reduce heating costs.

Below are practical steps that can help keep your electric furnace running efficiently while lowering your monthly utility bills.

Replace or Clean the Furnace Filter Regularly

One of the most important maintenance tasks for any HVAC system is changing the air filter.

A dirty filter restricts airflow, forcing the furnace to work harder to push warm air through the system. This increases energy consumption and can also lead to overheating and premature component failure.

Homeowners should typically replace or clean their furnace filter every 1 to 3 months, depending on the type of filter, presence of pets, and overall dust levels in the home.

Seal Air Leaks Around the Home

Many homes lose a significant amount of heat through small air leaks. Common areas include:

• Around windows and doors

• Electrical outlets and switches on exterior walls

• Attic access panels

• Plumbing and wiring penetrations

• Basement rim joists

Sealing these leaks with weatherstripping or caulk helps keep warm air inside the home and reduces the workload on the furnace.

Improve Attic Insulation

Heat naturally rises, and without proper insulation, a large amount of heated air can escape through the attic.

Increasing attic insulation is one of the most effective ways to reduce heating costs. In colder climates like Ohio, attics typically benefit from insulation levels around R-49 to R-60.

Improving insulation helps maintain indoor temperatures and allows the furnace to run less frequently.

Use a Programmable or Smart Thermostat

Installing a programmable or smart thermostat allows homeowners to automatically lower temperatures when they are sleeping or away from home.

Even lowering the thermostat by a few degrees for several hours each day can lead to noticeable energy savings over the course of a heating season.

Smart thermostats can also help monitor usage patterns and improve temperature consistency throughout the home.

Keep Supply and Return Vents Clear

Furniture, rugs, and curtains can block airflow from HVAC registers.

Blocked vents prevent warm air from circulating efficiently and can create uneven temperatures throughout the home. This may cause the furnace to run longer cycles to maintain the thermostat setting.

Make sure all supply and return vents remain open and unobstructed.

Schedule Periodic HVAC Maintenance

Even though electric furnaces have fewer moving parts than gas furnaces, periodic inspection is still beneficial. A qualified HVAC technician can check:

• Heating elements

• Electrical connections

• Blower motor operation

• Safety controls

• Airflow performance

Routine maintenance helps identify small issues before they become costly repairs and keeps the system operating at peak efficiency.

Improve Overall Home Efficiency

Heating costs are not determined by the furnace alone. The efficiency of the entire home plays a major role.

Additional improvements that can reduce heating costs include:

• Upgrading older windows or adding storm windows

• Installing insulated window coverings

• Sealing ductwork in attics or crawlspaces

• Adding insulation to exterior walls

• Using ceiling fans on low speed to circulate warm air

These upgrades help retain heat inside the home and reduce the demand placed on the furnace.

The Role of a Home Inspection

A professional home inspection can identify several factors that affect heating efficiency, including insulation levels, air leakage, ductwork issues, and HVAC performance.

Understanding how these systems interact helps homeowners make informed improvements that can reduce energy consumption and improve overall comfort.
