How to Know When It’s Time to Replace Your Furnace

There are several signs that it may be time to replace your furnace, including:

  • Age: Most furnaces have a lifespan of between 15 and 20 years. If your furnace is approaching or exceeding this age, consider a replacement.
  • Efficiency: Furnaces that are more than 10 years old may not be as energy efficient as newer models. Replacing an older furnace with a newer, more energy-efficient model can help you save money on your energy bills.
  • Frequent repairs: If your furnace requires frequent repairs or if the cost of repairs is becoming significant, it may be more cost-effective to replace the unit.
  •  Noisy operation: If your furnace is making unusual noises, such as clanking, banging, or squealing, it may be a sign that it is reaching the end of its lifespan.
  • Uneven heating: If you are experiencing uneven heating or cold spots in your home, it may indicate that your furnace is not functioning properly and may need to be replaced.
  • Increased energy bills: If you see an increase in your energy bill without any changes in your usage habits or rates, it could be a sign that your furnace is not working as efficiently as it used to.

If you aren’t sure whether your furnace needs replacement, consider having an HVAC technician assess your furnace and advise you on its condition.

Electric Furnaces

Electric furnaces are powered by electricity and are known for their ease of use and low maintenance requirements. They do not require a flue or chimney and can be installed in a variety of locations, including basements, attics, and closets. Here are some of the pros and cons of electric furnaces:

Pros:

  •  Easy to install: Electric furnaces do not require a flue or chimney, making them easy to install in a variety of locations.
  •  Low maintenance: Electric furnaces do not require as much maintenance as gas furnaces and can last for many years with minimal upkeep.
  • Safe and clean: Electric furnaces do not produce harmful pollutants, making them a good choice for those with allergies or respiratory issues.

Cons:

  • Higher operating costs: Electric furnaces tend to have higher operating costs than gas furnaces, especially in areas with high electricity rates.
  • Limited heating capabilities: Electric furnaces may not be able to adequately heat large homes or homes in very cold climates as effectively as gas furnaces.

Gas Furnaces

Gas furnaces are powered by natural gas obtained from natural gas suppliers in ohio and are known for their efficiency and effectiveness in keeping a home warm. They require a flue or chimney for venting and typically need to be installed in a central location such as a basement or utility room. Here are some of the pros and cons of gas furnaces:

Pros:

  • Cost-effective: Gas furnaces are often more cost-effective to operate than electric furnaces, especially in areas where natural gas rates are low.
  • Highly efficient: Gas furnaces are highly efficient and can quickly heat a home, even in very cold climates.
  • Widely available: Natural gas is widely available in many areas and is considered a reliable fuel source.

Cons:

  • Requires a flue or chimney: Gas furnaces require a flue or chimney for venting, which can add to the installation costs and may limit placement options.
  • More Maintenance: Gas furnaces typically require more maintenance and thorough cleanings to maintain their efficiency.
  • Safety issues: Gas furnaces pose a risk of fire and carbon monoxide poisoning if not properly installed, maintained, and vented.

What to Know About Carbon Monoxide and Your Furnace

Carbon monoxide (CO) is a colorless, odorless, and toxic gas that is produced when certain fuels (such as natural gas, oil, propane, and wood) burn incompletely. When a furnace is not functioning properly, it can produce too much CO, which can build up in enclosed spaces and cause carbon monoxide poisoning. Symptoms of CO poisoning can include headache, dizziness, nausea, weakness, and confusion. In severe cases, it can lead to unconsciousness or death.

Carbon monoxide can form in a furnace in several ways. Some common causes include:

  • A blocked or restricted flue or chimney prevents the proper venting of CO outside
  • A malfunctioning burner or heat exchanger can cause incomplete combustion and the production of CO
  •  A cracked heat exchanger can allow CO to leak into the living space
  •  Improper installation or maintenance can lead to faulty operation and the production of CO

Gas or Electric Furnace – The Choice is Yours

The choice between an electric and gas furnace ultimately comes down to your personal preferences and the specific needs of your home. If electricity rates from your energy provider are fairly low, an electric furnace may be the more cost-effective option. 

If you have a large house or are experiencing excessively cold temperatures, a gas furnace may be a better fit, as it can quickly and effectively heat your home. Additionally, it is also important to consider the availability of natural gas in your area and the cost of installation, as well as ongoing maintenance costs and safety issues.

If you’re still unsure which type of furnace is best for your home, it’s a good idea to consult with an HVAC professional. They can assess your specific needs and help you make an informed decision. Ultimately, the goal is to have a furnace that is efficient, safe, and cost-effective.
