Purchasing a new furnace may not be a priority right away. But it’s smart to know the things that will likely impact your choice when you’re ready to buy. Here are seven things you’ll want to think about when you're due for furnace replacement in Gaithersburg.
1. Size and Installation Quality
To run at maximum efficiency and comfort, your furnace must be properly sized for your home. When it comes to furnaces, bigger is definitely not better. We often get requests from customers to purchase a big furnace in the mistaken belief that a larger furnace is either more dependable or will offer better comfort.
The reverse is true. Oversized furnaces will short cycle, or continuously turn on and off. This leaves you cold, with more expensive energy bills and a furnace that could need replacing much sooner.
This is why it’s crucial to work with the right company when buying a new furnace. Even if it’s the correct size but installed wrong, the U.S. Department of Energy says you could forfeit as much as 30% of your energy efficiency.
Another crucial component of installation is ductwork. If yours is old or designed wrong, you might have issues with sound or comfort. A furnace is only as effective as the duct system it’s attached to.

2. Energy Efficiency
Furnaces are ranked by a term called AFUE, or annual fuel utilization efficiency. Like miles per gallon on cars, this rates the annual gas consumption of a furnace. The greater the number, the less gas is spent during the heating process.
If your present furnace is 15 years old, it’s likely rated well below 80 AFUE. As an example, if your HVAC system is 70 AFUE, you’re wasting up to 30 cents of each dollar you spend on heating.
Here’s how AFUE ratings work today:
- 80 AFUE—minimum efficiency rating in the U.S. and Canada.
- 90 AFUE—ENERGY STAR® rating for furnaces in the U.S. South.
- 95 AFUE—ENERGY STAR® rating for furnaces in the U.S. North and Canada.
- 98 AFUE—best efficiency rating available.
3. Blower Motor Technology
As you evaluate new furnaces there is one more important thing to consider: blower technology. This part moves air throughout your home. And it also uses a lot of electricity, so it’s important to be familiar with your options.
There are three kinds of blowers available on furnaces today. They include:
- Standard blower motor. Furnaces that aren’t ENERGY STAR rated have a standard blower motor that’s been mostly the same for the past 30 years. This motor is the least expensive and also the least energy efficient.
- Constant torque motor. This technology strikes a balance between cost and energy efficiency. It delivers an electrical efficiency boost over a standard motor design.
- Variable-speed motor. The most energy-efficient furnaces can run at different speeds. Instead of running at full blast 24/7, they will quietly operate at a low or medium speed at times. This helps enhance your comfort while keeping energy costs down, both in the winter and summer. And it also keeps indoor humidity in check.
4. Sound Reduction Technology
Sound has become a very significant consideration with furnace installation, so another great improvement has been keeping noise under control. Some of these features include:
- Sealed and insulated cabinets
- Variable-speed blower technology
- Nearly silent gas burners
With this technology, you might not even be aware that your furnace is running.
5. Smart Thermostat
You probably have a programmable thermostat, but it's quite possible you probably aren’t maximizing your energy savings. These thermostats can be challenging to program, particularly if your schedule varies from day to day.
A smart thermostat eliminates all the guesswork about energy efficiency. Many models can learn from your temperature preferences and then create an energy-saving schedule to match. They also know when you’re home or away and will adjust your heating and cooling as necessary.
As a bonus, you’ll also be able to keep tabs on and adjust your settings from just about anyplace on your phone. Some models can even notify you if they detect a problem with your furnace or remind you when it’s time to replace your air filter.
There’s a major difference in furnace quality and reliability. Like any large purchase, we believe it’s wisest to go with a major brand name. With a top brand like Lennox® or Goodman®, you’ll have more assurance in the technology and that the manufacturer will uphold its product warranty over the long haul.
Furnaces typically have two primary warranty coverage areas:
- Heat exchanger. This is the center of the furnace and the costliest component to replace. This part typically has a 20-year limited warranty or lifetime limited warranty, but this can differ based on the manufacturer and furnace model.
- Main components. This includes the blower motor, electronic controls, ignitors and other key parts. Warranties can vary from as short as a one-year limited warranty to as much as a 10-year limited warranty.
When reviewing warranty coverage, it’s essential to know it's limited. So, you should make sure you get the limitations. For instance, nearly all standard manufacturer warranties only include the cost of the replacement part, not labor. And labor on a new heat exchanger could get very expensive.
Once your new furnace is running, make sure you complete the product registration right away. Many manufacturers may reduce the warranty term if the product registration is not completed. This step is easy and usually only takes a few minutes.
How much does all this cost anyhow? It could range from $1,700 for a basic furnace, or $5,500 or more for a high-efficiency system.
As you consider these costs and the affect on your budget, remember that unlike nearly every other appliance you may need to purchase, your new furnace may help pay for itself from the monthly energy savings it offers.
A couple of additional ways to save include:
- Replacing your air conditioner at the same time.
- Buying at the right time, such as in early fall, mid-winter and early spring. You may be able to get extra discounts and rebates during this slower season.
- Reap the benefits of rebates from the federal and state government, as well as from your local utility company. We can help you navigate this process.
- Finance your new furnace or enroll in our exclusive HVAC Advantage Program™. For just one low monthly fee, you’ll get a new furnace with repairs and maintenance included.*
How Do I Know When to Replace My Furnace?
Now that you know what to search for in a new furnace, when should you replace your outdated one? Here are a few tips from our Experts that will help you make that decision.
Heating systems usually last 15–20 years. How long yours will keep going depends on whether you’ve done furnace maintenance, where you live and your temperature preferences. If you’re in a place with harsh winters, your furnace will operate more often, potentially making it wear out faster. The same applies if you like to keep your home at a hotter temperature.
Repair Frequency and Cost
Just like any appliance, as furnaces get older, the potential for frequent furnace repair increases. If your system is more than 15 years old, those repairs can be especially costly. Common and costly repairs on an older furnace include:
- Blower motor failures
- Ignition control failures
- Heat exchanger failures
If repairs are more than the half the price of a new furnace, it’s generally best to replace it.
Furnaces older than 15 years can be very inefficient. You could be throwing away as much as 30% of the money you spend to keep your home warm. Excessive energy costs and the desire to decrease energy consumption are also strong reasons to think about replacing your furnace. In fact, an independent study by Decision Analyst shows nearly 20% of homeowners who recently replaced their furnace specifically did so to lower their utility bills.
