How to Improve Your Furnace’s Heating Ability

Furnaces are an excellent heating solution. With the ability to achieve higher heat output than most heating systems, they are energy-efficient and reliable. In addition, you can use the furnace to improve your home’s indoor air quality by installing an air filtration system, humidifier, or air purifier right inside its system.

Generally, furnaces are a handy component in the home when it comes to keeping yourself or your family warm and comfy during the cold months. While older low-efficiency units cannot match some alternative heating solutions newer high-efficiency models can rock up to 98% efficiency, which balances well when you factor in fuel affordability.

Nonetheless, no matter the rating of your furnace, here are tips to help you improve its efficiency and bring down your energy costs.

Change or Clean the Filter Regularly

The filter helps keep off dust and other objects that might clog the furnace and reduce its heating efficiency. But with time, the trapped debris prevents smooth airflow causing the furnace to work harder to pull air through. For this reason, you should change or clean (if it’s reusable) it at least every three months. However, you should check it monthly during the winter due to the increased use.

Use a Smart Thermostat

Upgrading to a programmable thermostat helps improve the furnace’s efficiency by preventing unnecessary heating. It allows you to program the heating based on your needs. For instance, during the cold months, you can set the temperature higher during the day/when you are awake and lower at night. Also, you can set schedules for the weekdays when no one is home and on weekends when you’re at home.

However, note that you should avoid frequent adjustments as this can reduce efficiency. Generally, setting the temperature at 68°F during winter should be sufficient to keep you warm when you are awake.

Keep the Registers Open and Clear the Area Around the Furnace

You should check the registers’ cover regularly to ensure there’s no trapped dust. Also, keeping off furniture or other items blocking the registers can enhance free air circulation, thereby boosting the furnace’s efficiency.

Maintain the Furnace Periodically

Having regular furnace maintenance can boost the system’s efficiency significantly. A tune-up and thorough inspection by a professional is necessary every year to help the furnace operate at peak efficiency. The inspector can also clean the parts to increase airflow and replace any faulty parts that might strain the system or pose a safety hazard to your family.

Reduce Your Home’s Heating Needs

Another indirect but effective way of improving your furnace’s efficiency is by reducing your home’s heating needs. You can attain this through various ways such as:

  • Dressing warmly to reduce the need for heating
  • Using fans (ceiling) to circulate the warm air around the room
  • Drawing curtains during the night to block cold air from flowing into the house
  • Maintaining good humidity levels
  • Sealing off drafts on the doors, windows, and other surfaces that may let the air out
  • Installing energy-efficient windows


A furnace comes in handy when the need for heating your home during cold weather arises. Besides keeping you and your family warm and comfortable, it can help improve the air quality around the house when the weather can’t allow you to open the windows. However, like any other heating system, the energy bills can quickly pile as a result.

We hope these tips will help improve your furnace’s heating ability and reduce your costs.
