Purchasing a new furnace may not be a concern right away. But it’s wise to learn the things that will likely impact your choice when you’re ready to buy. Here are seven things you’ll want to consider when you're due for furnace replacement in Longmont.
1. Size and Installation Quality
To run at peak 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 install a big furnace in the misguided belief that a larger furnace is either more dependable or will offer better comfort.
The reverse is true. Oversized furnaces will short cycle, or constantly turn on and off. This leaves you cold, with more expensive energy bills and a furnace that could wear out much sooner.
This is why it’s crucial to work with the right company when purchasing a new furnace. Even if it’s the right size but improperly installed, 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 improperly designed, you might have issues with noise 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 higher the number, the less gas is wasted during the heating process.
If your present furnace is 15 years old, it’s likely ranked well below 80 AFUE. As an example, if your HVAC system is 70 AFUE, you’re throwing away up to 30 cents of each dollar you spend on heating.
Here’s how AFUE ratings work now:
- 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—highest efficiency rating available.
3. Blower Motor Technology
As you compare new furnaces there is one more important thing to consider: blower technology. This part circulates air throughout your home. And it also consumes a lot of electricity, so it’s essential to be familiar with your options.
There are three kinds of blowers available on furnaces nowadays. They include:
- Standard blower motor. Furnaces that aren’t ENERGY STAR rated have a standard blower motor that’s been relatively the same for the past 30 years. This motor is the least costly and also the least energy efficient.
- Constant torque motor. This technology finds a balance between cost and energy efficiency. It delivers an electrical efficiency boost over a traditional motor design.
- Variable-speed motor. The most energy-efficient furnaces can operate at different speeds. Instead of operating at full blast 24/7, they will quietly run at a low or medium speed at times. This helps improve your comfort while keeping energy costs down, both in the winter and summer. And it also keeps indoor humidity under control.
4. Sound Reduction Technology
Sound has become a very significant consideration with furnace installation, so another dramatic improvement has been keeping noise under control. Some of these features include:
- Sealed and insulated cabinets
- Variable-speed blower technology
- Whisper-quiet gas burners
With this technology, you might not even be aware that your furnace is running.
5. Smart Thermostat
You probably use a programmable thermostat, but chances are you probably aren’t making the most of your energy savings. These thermostats can be challenging to program, especially if your schedule varies from day to day.
A smart thermostat removes all the guessing about energy efficiency. Many models can learn from your temperature preferences and then produce an energy-saving schedule to match. They also know when you’re home or away and will adjust your heating and cooling as needed.
As an extra perk, you’ll also be able to monitor and adjust your settings from just about anywhere on your phone. Some models can even alert you if they detect a problem with your furnace or remind you when it’s time to change your air filter.
There’s a major difference in furnace quality and reliability. Like any large purchase, we think it’s best 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 stand by its product warranty over the long haul.
Furnaces typically have two main warranty coverage areas:
- Heat exchanger. This is the heart 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 vary based on the manufacturer and furnace model.
- Main parts. This involves the blower motor, electronic controls, ignitors and other key parts. Warranties can range from as little as a one-year limited warranty to as much as a 10-year limited warranty.
When going over warranty coverage, it’s important to know it's limited. So, you should make sure you understand the limitations. For example, nearly all standard manufacturer warranties only cover the cost of the replacement part, not labor. And labor on a new heat exchanger could get costly.
Once your new furnace is installed, make sure you complete the product registration right away. Many manufacturers may limit the warranty term if the product registration is not done. This step is easy and typically only takes a few minutes.
How much does all this cost anyhow? It could vary from $1,700 for a basic furnace, or $5,500 or more for a high-efficiency system.
As you think about these costs and the impact to 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 provides.
A couple of additional ways to save include:
- Replacing your air conditioner simultaneously.
- Buying at the ideal time, such as in early fall, mid-winter and early spring. You may be able to get additional discounts and rebates during this less busy season.
- Reap the benefits of rebates from the federal and state government, as well as from your local utility company. We can help you figure out this process.
- Finance your new furnace or sign up for our exclusive HVAC Advantage Program™. For just one low monthly fee, you’ll receive a new furnace with repairs and maintenance included.*
How Do I Know When to Replace My Furnace?
Now that you know what to look 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 typically last 15–20 years. How long yours will last depends on whether you’ve done furnace maintenance, where you live and your desired temperature. If you’re in a place with harsh winters, your furnace will operate more frequently, potentially making it wear out faster. The same goes if you like to keep your home at a hotter temperature.
Repair Frequency and Cost
Just like any appliance, as furnaces age, the potential for frequent furnace repair increases. If your system is more than 15 years old, those repairs can be especially expensive. Common and expensive 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 wasting as much as 30% of the money you spend to heat your home. Excessive energy costs and the desire to decrease energy use are also strong reasons to think about replacing your furnace. In fact, an independent study by Decision Analyst reveals nearly 20% of homeowners who recently replaced their furnace specifically did so to reduce their energy bills.
