Buying a new furnace may not be a concern right away. But it’s smart to learn the things that will likely influence your selection when you’re ready to buy. Here are seven things you’ll want to think about when you're due for furnace replacement in Savannah.
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 provide better comfort.
The reverse is true. Large furnaces will short cycle, or constantly turn on and off. This leaves you uncomfortable, with more expensive energy bills and a furnace that could wear out much sooner.
This is why it’s important to work with the right company when buying 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 key component of installation is ductwork. If yours is old or designed wrong, you might have problems with sound or comfort. A furnace is only as good as the duct system it’s attached to.
At Coastal Service Experts, our Expert HVAC technicians are ACE certified, which means they’re skilled in repairing and installing various kinds of home comfort systems. Besides technical skill, our technicians are also trained in treating you ethically. We also support our work with a 100% satisfaction guarantee for a year.*
2. Energy Efficiency
Furnaces are ranked 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 spent during the heating process.
If your current 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 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—best efficiency rating available.
3. Blower Motor Technology
As you compare new furnaces there is one more important consideration: blower technology. This part circulates air throughout your home. And it also consumes 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 relatively unchanged 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 cost and energy efficiency. It provides 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 blast 24/7, they will quietly run 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 under control.
4. Sound Reduction Technology
Sound has become a very important 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
- Nearly silent 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, especially if your schedule changes from day to day.
A smart thermostat removes 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 recognize when you’re home or away and will adjust your heating and cooling as needed.
As a bonus, 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 detect 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 best to go with a major brand name. With a leading 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 typically have two main warranty coverage areas:
- Heat exchanger. This is the center 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 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 understand the restrictions. 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 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 usually only takes a few minutes.
How much does all this cost anyway? It could vary from $1,700 for a basic furnace, or $5,500 or more for a high-efficiency model.
As you consider these costs and the affect on 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:
- Getting a new air conditioner simultaneously.
- Purchasing at the ideal 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.
- Reap the benefits 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 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 ideas from our Experts that will help you decide.
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 temperature preferences. If you’re in a place with harsh winters, your furnace will operate more often, potentially making it wear out sooner. 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 likelihood for frequent furnace repair increases. If your system is more than 15 years old, those repairs can be especially expensive. 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 cost of a new furnace, it’s generally best 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 keep your home warm. Excessive energy costs and the desire to reduce energy use are also strong reasons to consider 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 reduce their energy bills.
