Types of furnaces

Most Americans use a forced-air system, like a furnace to heat their homes. Furnace technology is simple. A heating source burns natural gas, propane, or oil, and heats incoming air. This warm air is forced through your home’s ductwork and venting, and heats your home. Furnace technology has come a long way and newer models can have  efficiency ratings as high as 98.5%. The average new furnace cost varies depending on efficiency ratings, fuel source, and other factors.

Oil furnaces

Oil furnaces are common in areas that have limited access to natural gas. Oil furnaces require heating oil, which is stored in a tank on your home’s property. Your monthly oil furnace cost will rise and fall depending on the price of oil. However, a number of oil furnace models are able to burn a blend of heating oil and biodiesel, which is cleaner than pure heating oil. Because biodiesel also lubricates your oil furnace system, a furnace fuelled by biodiesel may have lower service costs.

Natural gas furnace vs propane furnace

The natural gas furnace cost and the cost of a propane furnace are comparable in terms of energy efficiency, safety, and environmental footprint. When compared unit for unit, propane is twice as efficient as natural gas. This means you can use half as much propane to do the same job as natural gas. That being said, the cost of a propane furnace is slightly higher than a natural gas furnace. Making the choice between two fuels is a matter of personal preference.

Gas furnaces

A gas furnace heats your home by burning natural gas or propane. The flames heat up a metal heat exchanger, which transfers its heat to incoming air. The gas furnace’s blower forces the heated air into your home’s ductwork and distributes it throughout your home. As the warm air fills your home, cooler air is drawn back into the gas furnace via return ducts, and the process begins again.

The average new furnace cost varies depending on the model, efficiency rating, and other factors.

InHome’s experts are ready to talk you through our available gas furnaces and oil furnaces, and help you choose the best furnace for your home.

Benefits of a new system

Gas or oil furnaces that filter airborne dust particles, bacteria, fungi, and microbes

Healthier home

A new furnace means better air quality in your home. New gas furnaces and oil furnaces have top-quality filters that rid your home of airborne dust particles, bacteria, fungi, and microbes. Plus, you can opt for additional add-ons like humidifiers or UV cleaners when you upgrade.

Quiet, efficient replacement furnaces

Peace and quiet

Older gas furnaces or oil furnaces can be noisy, popping, humming, or clicking. No matter which of our furnaces you choose for your replacement furnace, they will all be quieter than an older model. New furnace technology is quieter than ever, comparable to the sound of your refrigerator. Ask us about our quietest furnaces for when it’s time for your replacement furnace.

Furnaces installed in MA with better warranties

Better warranties

Today’s furnaces are designed to last longer than ever, which means you need a warranty to match. InHome only installs furnaces with top warranties, so you’re well covered in case of repairs or replacement parts. Speak to one of our experts today.

Signs it’s time to upgrade

Your furnace is more than 10 years old

Even with regular maintenance, you will benefit from a furnace replacement after about 15 years. Older furnaces are more likely to have issues and they cost more to run. Plus, technology has improved dramatically in the past 10 years.

You see an increase in your energy bill

When your gas furnace or oil furnace is not working efficiently, it uses more energy than normal, and costs more to run.

Your furnace is noisier than it used to be

Strange noises usually mean you need a repair. If your furnace is on the older side, consider a replacement rather than another fix.

Your furnace flames are yellow

A new high-efficiency furnace will always produce a clean blue flame to heat your home. If the flames coming from the burners are yellow, your old furnace is producing carbon monoxide, or it’s a sign of a dangerous gas leak that needs to be repaired right away.

Your home isn’t as comfortable as it used to be.

This is another sign that your furnace isn’t working efficiently. If your furnace isn’t doing its job, it’s time for a replacement furnace.

Replacement gas or oil furnaces are more energy efficient

Safety first

If your furnace is older, it may not meet current guidelines for furnace safety and operation. It may even pose health and safety risks like fire hazard, gas leaks, or carbon monoxide poisoning. While the new oil furnace cost or the new gas furnace cost is an investment, a newer, high efficiency furnace means lower monthly bills and no worries about your safety. 

New safe, efficient replacement furnaces lower carbon monoxide risk

Get more efficient with an upgrade

Furnaces are rated with an annual fuel-utilization-efficiency (AFUE) score, which tells you how well your furnace converts energy into useable heat. Older gas furnaces or oil furnaces can have AFUE rating as low as 65%, whereas new furnaces are required to have an AFUE rating of at least 78%. And if you splurge on an ultra high-efficiency furnace, your furnace replacement can be up to 97% efficient.

Say you have a furnace with a 90% AFUE rating. This means your furnace converts approximately 90% of the energy it draws into pure heat for your home. There is just 10% heat loss through the vents, chimney, open windows or doors, and other sources.

Furnaces with a higher AFUE rating, come with a higher replacement furnace cost, but your monthly expenses will be much lower.

Further your furnace’s efficiency

If you’re going to invest in a new oil furnace or a new gas furnace, make sure the rest of your home is as energy efficient as possible. Anything you can do to minimize heat loss will help your replacement furnace work efficiently and further reduce your monthly costs.

Guard your home against heat loss

Ensure your attic and walls are properly insulated.

Add caulk or weather stripping around your doors and windows to prevent heat from escaping.

Ensure cooling system ducts in your crawl space and attic are properly insulated.

Have your chimney cleaned.

Ensure your ceiling fans to spin clockwise, so they blow rising heat down.

Install programmable thermostats and set them to lower the temperature at night, or if you’re away. Did you know programmable thermostats can save you an additional 10% on your energy bills?

How do I know what size furnace is right for my home?

The best way to determine the correct furnace size for your home is to choose a reputable installer. An expert will be able to calculate your home’s heating needs based on industry standards. These calculations take the climate and your home’s size, design, and construction into account.

A furnace that’s too small for your home won’t keep your house comfortable in extremely cold weather. Most furnaces are slightly bigger than necessary to avoid this possibility, but a furnace that’s too large will cycle on and off more frequently. This causes wear and on the components, uncomfortable fluctuations in temperature, and noisy airflow—not to mention, it wastes a lot of energy. When it’s time for your replacement furnace, speak to one of our experts about the right size furnace for your home.

What are the most important features of a new furnace?

Each new gas furnace or oil furnace offers a similar array of features, which vary depending on the brand and the furnace cost. Generally speaking, higher-efficiency furnaces will have more features, but some manufacturers offer them on their entire range. When choosing your replacement furnace, ask about the following features:

Variable-Speed Blowers. When less heat is needed, variable-speed blowers deliver air slower and make less noise. Gas furnaces and oil furnaces with this feature produces fewer drafts and uncomfortable temperature fluctuations.

Variable Heat Output. This feature can automatically vary the amount of heat the furnace delivers, greatly increasing its efficiency and your home’s comfort. With variable heat output, your furnace will fire at about 60% of its maximum heat output during milder weather. When your heating needs are greater, it automatically switches to maximum output. Variable heat output  is generally available on furnaces with variable-speed blowers. 

Air Filtration. Reduce the amount of dust and other airborne particles in your home with a high-quality filter. Consider an electrostatic filter, which uses an electrical charge to help trap particles, or a HEPA  filter, which can significantly reduce the amount of dust blown through your heating system. Clean air means a healthy home.  

Dual Heat Exchanger. Heat exchangers draw heat from the fuel your furnace burns. High-efficiency furnaces often employ two heat exchangers to draw as much heat as possible. Furnaces with high efficiency ratings typically have dual heat exchangers.

Ignition System. Furnace manufacturers are moving away from pilot lights—flames that burn continuously, waiting to ignite the burners in your furnace. Newer high-efficiency furnaces employ intermittent, direct spark, or hot-surface ignition, which do not require a constant flame. Furnaces with ignition systems are more efficient and have higher AFUE ratings.

What are "zones"?

A zone is an area in your home, which is controlled by its own thermostat. A home can have anywhere from 1-5 zones based on size, layout, or additions.  Zoned HVAC uses dampers in the ductwork to regulate and redirect air to specific areas of the home. Zoning your home has several benefits, including the elimination of hot or cold spots, and having individual control of a room’s temperature—think cool bedrooms and a cozy living room, and forget about arguing over the thermostat.

Zones are most effective in multi-level homes. Because heat rises, the upper levels are always warmer than the lower levels. Installing separate zones creates more even temperatures throughout your home. Speak to one of our experts about installation cost and the best heating for your home. 

What is “heat load”?

Heat load is the amount of heat energy your home needs in order to maintain the desired indoor temperature. Your home’s heat load depends on its size, construction, insulation, number of windows, and other factors. The heat load will also determine the size and model of furnace your home needs. Speak to one of our experts about the new furnace cost and the best furnace for your home.

What is an Energy Star Rating?

ENERGY STAR helps easily identify high-quality, energy efficient products. To earn the ENERGY STAR, a product, like a furnace, must meet strict energy efficiency criteria set by the US Environmental Protection Agency or the US Department of Energy. Products with the ENERGY STAR logo are generally 15% more efficient than the minimum federal standards. ENERGY STAR products help you save on your monthly bills and help the planet by reducing energy usage.
