6 Common Mistakes That Strain Your Furnace

As temperatures drop, your furnace works overtime. However, common mistakes can lead to undue strain on this essential system. Here, we’ll identify six typical errors that may be overworking your furnace and how Miller Oil Company can help correct these to boost longevity and efficiency.

1. Ignoring Regular Furnace Maintenance

Regular maintenance is crucial for furnace efficiency and extending its lifespan. Neglecting routine checks allows minor issues to escalate into significant problems, causing accumulated wear and tear. This neglect forces the furnace to work harder to maintain the desired temperature. It increases energy consumption and the risk of breakdowns. 

Miller Oil Company provides professional maintenance services that can prevent these issues, ensuring your furnace operates smoothly and economically throughout the year.

2. Poor Insulation and Air Leaks

Inadequate insulation and air leaks in your home can significantly overburden your furnace. These gaps force the furnace to compensate for the lost heat by running longer and more frequent cycles, which shortens the unit’s lifespan and hikes up energy bills. 

Common areas where leaks occur include windows, doors, and attic spaces. Proper insulation and sealing of these leaks are essential for maintaining an efficient heating system. Miller Oil Company recommends using expert services to enhance your home’s insulation and seal any leaks, ensuring your furnace operates efficiently and cost-effectively.

3. Incorrect HVAC Thermostat Settings

Setting your thermostat to extreme temperatures can cause your furnace to operate continuously, leading to unnecessary strain and increased wear. To maximize efficiency and comfort, setting your thermostat to a moderate temperature while you’re at home and lowering it slightly when you’re away or asleep. 

This strategy helps reduce the workload on your furnace and can significantly cut down on your heating costs. Miller Oil Company can help you determine and maintain optimal temperature settings that suit your daily routine and enhance furnace efficiency.

4. Clogged HVAC Filters

A dirty air filter restricts airflow by trapping dust, pet dander, and other airborne particles, forcing your furnace to exert more effort to circulate warm air. This increased workload makes the furnace work harder and less efficiently, leading to higher energy costs and quicker wear on its components. 

Filters can become dirty more quickly in homes with pets, smokers, or high dust levels, and in these cases, it may be necessary to change filters as often as every month. Regularly replacing your furnace filter according to Miller Oil Company’s recommended schedule can maintain optimal furnace performance and air quality.

5. Oversized or Undersized Furnace

A furnace that is not correctly sized for your home can lead to many efficiency and operational problems. An oversized furnace will cycle on and off more frequently, which can cause excessive wear on components and inefficient heating. Conversely, an undersized furnace will struggle to adequately heat the space, running continuously and using excessive energy. 

Signs of a mismatch include uneven heating, frequent repairs, and soaring energy bills. Miller Oil Company can evaluate your heating needs and recommend a properly sized furnace for your home, ensuring efficient and reliable performance.

6. Blocking or Closing Heating Air Vents

Closed or blocked air vents increase the pressure in your furnace’s ductwork, forcing it to work harder to distribute air, leading to decreased efficiency and potential damage. To ensure your furnace operates optimally, keep all vents clear of furniture, rugs, and drapes. It’s essential to maintain an open layout where air can circulate freely. 

Regularly check that vents in lesser-used rooms are open to maintain balanced airflow throughout your home. Miller Oil Company can guide optimal room layouts and vent management to enhance your furnace’s performance and longevity.

Recognizing Signs of an Overworked Furnace

An overworked furnace can show several telltale signs that require immediate attention to prevent more significant issues:

  • Frequent Furnace Cycling On and Off: A furnace that constantly turns on and off may be improperly sized or struggling to maintain the set temperature.
  • Unusual HVAC Noises: Banging, whining, or rattling indicate mechanical problems or airflow obstructions.
  • Slow Heating: If your house takes longer to warm up, it could mean your furnace is losing efficiency.
  • Increased Energy Bills: Higher bills without increased usage are a classic sign of decreased furnace efficiency.
  • Cold Spots in Rooms: Uneven heating in different areas often points to issues with ducts or the furnace.
  • Excessive Dust or Poor Air Quality: Increased airborne particles can result from poor air circulation or filter problems.

Addressing the signs of an overworked furnace promptly is crucial to preventing more significant and costly problems. Recognizing and responding to these early warning signs ensures your furnace is serviced, repaired, or adjusted before minor issues escalate into major breakdowns. This proactive approach extends the lifespan of your furnace and maintains its efficiency and reliability, reducing unexpected costs and enhancing home comfort throughout the colder months.

Furnace Efficiency FAQs

What Are the Benefits of a Variable Speed Furnace in Reducing Wear and Tear? 

A variable-speed furnace fine-tunes its blower motor speed to precisely match the heating demands of your home at any moment, avoiding the harsh start-stop cycles common with traditional models. This feature not only ensures a more consistent and comfortable indoor climate but also significantly reduces wear and tear on the system. The result is enhanced energy efficiency, prolonged furnace lifespan, and lower utility bills.

How Does Outdoor Temperature Affect My Furnace’s Workload? 

During colder weather, your furnace must work harder to maintain the desired indoor temperature, leading to increased frequency and duration of cycles. This additional workload can strain the furnace, potentially causing overheating and premature mechanical wear. Proper insulation and regular maintenance can mitigate these effects, ensuring your furnace operates efficiently even in the coldest conditions.

Can Installing a Humidifier Help Reduce Furnace Strain? 

Absolutely. Integrating a humidifier with your heating system helps maintain optimal indoor humidity levels, making lower temperatures feel more comfortable. Consequently, you can set your thermostat lower, reducing the furnace’s workload and enhancing energy efficiency. This not only prolongs the life of the furnace but also improves your comfort and can help reduce static electricity in your home.

What Is the Lifespan of a Well-Maintained Furnace? 

A well-maintained furnace typically lasts between 15 to 20 years, depending on the make and model. Regular professional maintenance, such as annual servicing and timely repairs of worn or faulty components, is critical in extending your furnace’s operational life. These actions ensure that your furnace runs efficiently and reliably over its full potential lifespan.

How Often Should Ductwork Be Inspected to Support Furnace Efficiency? 

Ductwork should be professionally inspected at least every three years to check for leaks, blockages, or damage that could impact airflow and furnace efficiency. Regular inspections help ensure that your heating system isn’t working harder than necessary to distribute air throughout your home. This not only maintains your furnace’s efficiency but also helps keep energy costs down and improves the overall air quality in your home.

Conclusion

Keeping your furnace running efficiently involves avoiding common pitfalls such as neglecting maintenance, poor insulation, incorrect thermostat settings, clogged filters, and improper furnace sizing. Addressing these issues extends the life of your furnace and enhances overall home comfort.
