Purchasing a new furnace may not be a priority in the immediate future. 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 Hurricane.
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 misguided belief that a larger furnace is either more dependable or will provide better comfort.
The reverse is true. Oversized furnaces will short cycle, or continuously 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 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 problems with noise or comfort. A furnace is only as effective as the duct system it’s attached to.
At Teays Valley Service Experts, our Expert HVAC technicians are ACE certified, which means they’re knowledgeable about repairing and installing various kinds 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 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 spent 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—highest efficiency rating available.
3. Blower Motor Technology
As you research 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 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 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 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 operating at full speed 24/7, they will quietly operate 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 in check.
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
- Nearly silent 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 maximizing 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 guessing 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 an extra perk, you’ll also be able to monitor and change 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 replace your air filter.
There’s a significant difference in furnace quality and reliability. Like any large purchase, we think it’s wisest 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 term.
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 differ based on the manufacturer and furnace model.
- Main parts. This involves the blower motor, electronic controls, ignitors and other important parts. Warranties can vary 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 get the limitations. For example, nearly all standard manufacturer warranties only include the cost of the replacement part, not labor. And labor on a replacing heat exchanger could get very expensive.
Once your new furnace is installed, make sure you finish the product registration immediately. Many manufacturers may reduce 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 anyhow? It could vary 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 provides.
A couple of other ways to save include:
- Getting a new air conditioner at the same time.
- Purchasing 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.
- 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 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 old 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 somewhere with harsh winters, your furnace will run more often, potentially making it wear out sooner. 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 likelihood for frequent furnace repair goes up. If your system is more than 15 years old, those repairs can be particularly 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 cost 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 keep your home warm. Excessive energy costs and the desire to reduce 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 lower their energy bills.
