Buying a new furnace may not be a concern in the immediate future. But it’s wise to learn the things that will likely influence your selection when you’re ready to buy. Here are seven things you’ll want to consider when it’s time for furnace replacement in Tempe.
1. Size and Installation Quality
To operate at peak efficiency and comfort, your furnace must be correctly sized for your home. When it comes to furnaces, bigger is definitely not better. We frequently 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. Large 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 buying a new furnace. Even if it’s the correct size but improperly installed, the U.S. Department of Energy says you could forfeit as much as 30% of your energy efficiency.
Another key component of installation is ductwork. If yours is old or designed wrong, you might have issues with noise or comfort. A furnace is only as effective as the duct system it’s attached to.

Besides technical skill, our technicians are also trained in treating you ethically. We also stand behind our work with a 100% satisfaction guarantee for a year.*
2. Energy Efficiency
Furnaces are rated by a term called AFUE, or annual fuel utilization efficiency. Like miles per gallon on cars, this measures 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 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—highest efficiency rating available.
3. Blower Motor Technology
As you evaluate new furnaces there is one more important thing to consider: blower technology. This part circulates air throughout your home. And it also uses a lot of electricity, so it’s important to know about 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 finds a balance between price and energy efficiency. It provides an electrical efficiency boost over a traditional 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 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 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 notice that your furnace is running.
5. Smart Thermostat
You probably use a programmable thermostat, but it's quite possible you probably aren’t making the most of your energy savings. These thermostats can be difficult to program, especially if your schedule changes from day to day.
A smart thermostat eliminates all the guesswork about energy efficiency. Many models can pick up on your temperature preferences and then create an energy-saving schedule to match. They also recognize when you’re home or away and will adjust your heating and cooling as necessary.
As an extra perk, you’ll also be able to monitor and change your settings from just about anyplace on your phone. Some models can even alert you if they find a problem with your furnace or remind you when it’s time to replace your air filter.
There’s a significant difference in furnace quality and reliability. Like any big purchase, we think it’s wisest to go with a major brand name. With a top brand like Lennox® or Goodman®, you’ll have more confidence in the technology and that the manufacturer will uphold its product warranty over the long haul.
Furnaces usually have two main warranty coverage areas:
- Heat exchanger. This is the heart of the furnace and the most expensive 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 parts. 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 important to know it's limited. So, you should make sure you understand the restrictions. For example, 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 installed, make sure you complete the product registration immediately. Many manufacturers may limit the warranty term if the product registration is not done. This step is simple and typically only takes a few minutes.
How much does all this cost anyway? It could range from $1,700 for a basic furnace, or $5,500 or more for a high-efficiency model.
As you think about these costs and the impact to your budget, remember that unlike nearly every other appliance you may need to buy, your new furnace may help pay for itself from the monthly energy savings it offers.
A couple of other ways to save include:
- Getting a new air conditioner at the same time.
- 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 slower season.
- Take advantage of rebates from the federal and state government, as well as from your local utility provider. We can help you navigate this process.
- Finance your new furnace or sign up for 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 ideas from our Experts that will help you make that decision.
Heating systems usually last 15–20 years. How long yours will last 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 run more often, potentially making it wear out sooner. The same applies if you like to keep your home at a warmer temperature.
Repair Frequency and Cost
Just like any appliance, as furnaces age, the likelihood for frequent furnace repair increases. If your system is more than 15 years old, those repairs can be especially costly. Common and expensive repairs on an older furnace include:
- Blower motor failures
- Ignition control failures
- Heat exchanger failures
If repairs are greater than the half the price of a new furnace, it’s generally best to replace it.
Furnaces older than 15 years can be extremely 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 consumption are also strong reasons to consider 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 lower their energy bills.
