Routine maintenance is essential for efficiency. Signs that you may need a maintenance check include:

• Strange noises like buzzing, rattling, or grinding.
• Uneven heating or cooling between rooms.
• Increased energy bills without a change in usage.
• Poor or weak airflow from vents.
• Dirty or clogged filters.
• The system cycling on and off frequently.

 To improve efficiency and lower costs, you can:

• Schedule regular maintenance.
• Upgrade to a high-efficiency system with higher SEER/AFUE ratings.
• Seal air leaks around doors, windows, and ducts.
• Install a programmable or smart thermostat.
• Use ceiling fans to help circulate air.
• Add insulation to keep heat in during winter and out during summer.

SEER (Seasonal Energy Efficiency Ratio): Measures the cooling efficiency of air conditioners and heat pumps.

AFUE (Annual Fuel Utilization Efficiency): Measures how efficiently a furnace converts fuel into usable heat. Higher ratings indicate better efficiency and lower energy bills.

Common causes include:

• Thermostat Settings: Ensure it is set to “heat” and the temperature is higher than the room temperature.
• Ignition Issues: The pilot light may be out or the ignition system could be faulty.
• Clogged Filter: A dirty filter can cause the furnace to overheat and trigger a safety shutoff.
• Tripped Breaker: Check your electrical panel for a tripped furnace circuit breaker.

It is recommended to have your system serviced at least twice a year—ideally once in the fall for heating and once in the spring for cooling. Regular service extends system lifespan, improves efficiency, and reduces unexpected breakdowns.
