Types of Furnaces

Hot Oil Furnace

Hot oil furnaces, also known as oil-fired heating systems, work by burning oil to produce heat. Oil stored in a tank is pumped into the burner, where it’s mixed with air and ignited. The resulting flames heat a heat exchanger, which warms air before it’s distributed throughout your home via ducts.

Gas Furnace

Gas furnaces operate on a similar principle but use natural gas as their fuel source. Gas enters the burner and ignites, heating the exchanger. This heated air is then circulated through your home. Gas furnaces require less maintenance compared to oil furnaces.

Can I Retrofit My Old Furnace?

You don’t always have to part ways with an older furnace that’s still in solid working condition. Retrofitting can enhance its performance and bring it up to date without the cost of a full replacement. Here are some retrofit options to consider:

• Upgrade to a Programmable Thermostat
  Installing a programmable thermostat lets you take more control of your home’s heating schedule. This upgrade not only enhances convenience but also helps lower energy costs.
• Switch to an Electronic Ignition System
  Older furnaces often rely on standing pilot lights, which continuously burn fuel. Switching to an electronic ignition system lights the flame only when needed.
• Add High-Efficiency Burners
  Retrofitting your furnace with high-efficiency burners can significantly improve how cleanly and effectively it uses fuel. This means better heat output for less fuel consumed.
• Install Heat Recovery Ventilators (HRVs)
  For an older furnace, adding a heat recovery ventilator can help capture and reuse heat from exhaust gases, further improving your system’s energy efficiency.

Our technicians can help assess your furnace and guide you through the options to find the best, cost-effective enhancements for your system.

Common Signs That Your Furnace Needs Replacement

Sometimes retrofitting or repairing your furnace just won’t cut it. Here are some key signs it’s time to consider upgrading to a new furnace:

• Your furnace is over 20 years old and repair bills are stacking up. Most furnaces have a lifespan of 15-20 years. If yours is older than this and constantly needs repairs, it’s costing you more than it’s worth.
• You notice uneven heating or cold spots in your home. A furnace should heat your home evenly. If certain rooms are colder than others, it could mean your furnace is no longer working well.
• Carbon monoxide detectors near your furnace are going off. If your detectors are alerting you to a potential leak, it’s a serious warning sign your furnace may have a cracked heat exchanger or other safety issues.
• Energy bills have been creeping up without an explanation. Older furnaces often need to work harder to heat your home. If you’ve noticed a steady rise in your utility bills, it might be cheaper to switch to a more efficient model.

Tips to Keep Your Furnace in Tip-Top Shape

• Schedule Regular Tune-Ups: An annual check-up by our professional team can help identify and fix small issues before they become expensive repairs. 
• Change Your Filters Regularly: A clogged filter can reduce your furnace’s efficiency. Check your filters monthly and replace them every 1-3 months, depending on use and the type of filter. 
• Keep Vents Clear: Blocked vents make your furnace work harder, wearing out the system faster. Take a few minutes to check that furniture, curtains, or other items aren’t obstructing airflow.  
• Don’t Forget the Thermostat: Double-check that your thermostat settings are optimized for energy savings, especially during the colder months. Consider upgrading to a programmable or smart thermostat for even better control and efficiency. 
• Listen for Odd Noises: A properly functioning furnace should operate quietly. If you hear banging, squealing, or other unusual sounds, it could point to loose or failing components.

Factors to Consider When Choosing a New Furnace 

When guiding homeowners to the perfect furnace, there are several factors we take into account to ensure the best fit for your home and lifestyle. 

• Fuel Source: The choice between oil and natural gas can depend on your location and accessibility. For example, some Long Islanders don’t have access to natural gas. We’ll help you determine which fuel source works best for you. 
• Home Size & Layout: The size of your home and its layout play a big role in heating efficiency. For larger homes or those with multiple floors, we’ll assess your space to recommend a furnace that delivers consistent warmth. 
• Energy Efficiency: A furnace’s efficiency directly impacts your energy bills. We’ll help you find a model that balances high performance with lower operating costs.
• Environmental Concerns: If sustainability is a priority, we can find high-efficiency furnace options that reduce your carbon footprint while keeping your home cozy. 

Advantages of New Furnaces 

Upgrading to a modern gas or oil furnace offers a range of significant benefits, making it a smart investment for your home. 

• Better Efficiency: New furnaces have high Annual Fuel Utilization Efficiency (AFUE) ratings. This means they use far less energy to heat your home, reducing waste and minimizing your carbon footprint. 
• Reliability: Today’s furnaces are built with advanced materials, making them more durable and less prone to breakdowns.
• Quieter Operation: Modern furnaces are designed with noise-reducing features, so you can enjoy a cozy, warm home without the racket older units produce. 
• Cost Savings: Thanks to their improved efficiency, modern furnaces consume less energy, which directly translates to lower monthly utility bills.
