Purchasing a new furnace may not be a priority in the immediate future. But it’s wise to learn the things that will likely influence 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 Naples.
1. Size and Installation Quality
To run at maximum efficiency and comfort, your furnace must be correctly 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 misguided 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 uncomfortable, with higher energy bills and a furnace that could need replacing much sooner.
This is why it’s crucial to work with the right company when purchasing a new furnace. Even if it’s the correct size but improperly installed, the U.S. Department of Energy says you could lose as much as 30% of your energy efficiency.
Another key component of installation is ductwork. If yours is old or improperly designed, you might have problems with sound or comfort. A furnace is only as good as the duct system it’s attached to.
At Service Experts Heating & Air Conditioning, our Expert HVAC technicians are ACE certified, which means they’re knowledgeable about repairing and installing various types of home comfort systems. In addition to technical skill, our technicians are also trained in treating you fairly. We also support our work with a 100% satisfaction guarantee for a year.*
2. Energy Efficiency
Furnaces are rated by a term known as AFUE, or annual fuel utilization efficiency. Like miles per gallon on cars, this measures the annual gas consumption of a furnace. The greater the number, the less gas is wasted during the heating process.
If your current 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—best efficiency rating available.
3. Blower Motor Technology
As you evaluate new furnaces there is one more important consideration: blower technology. This part circulates air throughout your home. And it also uses a lot of electricity, so it’s essential to know about 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 mostly unchanged 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 price 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 operating at full speed 24/7, they will quietly run at a low or medium speed at times. This helps improve your comfort while keeping energy costs low, 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 noise management. 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 on.
5. Smart Thermostat
You probably use a programmable thermostat, but chances are you probably aren’t maximizing your energy savings. These thermostats can be challenging to program, particularly if your schedule changes from day to day.
A smart thermostat eliminates 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 a bonus, you’ll also be able to keep tabs on and change your settings from just about anywhere 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 big purchase, we believe 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 uphold its product warranty over the long haul.
Furnaces usually have two primary warranty coverage areas:
- Heat exchanger. This is the heart of the furnace and the most expensive component to replace. This part usually 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 range from as little as a one-year limited warranty to as long as a 10-year limited warranty.
When reviewing warranty coverage, it’s important to know it's limited. So, you should make sure you get the limitations. For example, nearly all standard manufacturer warranties only cover the cost of the replacement part, not labor. And labor on a replacing heat exchanger could get costly.
Once your new furnace is running, make sure you complete the product registration right away. Many manufacturers may limit 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 anyway? It could range from $1,700 for a basic furnace, or $5,500 or more for a high-efficiency model.
As you consider 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 provides.
A couple of additional ways to save include:
- Replacing your air conditioner simultaneously.
- 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 less busy season.
- Take advantage of rebates from the federal and state government, as well as from your local utility provider. 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 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 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 run more frequently, potentially making it wear out faster. 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 recommended to replace it.
Furnaces older than 15 years can be extremely inefficient. You could be throwing away as much as 30% of the money you spend to heat your home. High 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 reduce their utility bills.
