Purchasing a new furnace may not be a priority right away. But it’s smart to know the things that will likely impact 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 Raleigh.
1. Size and Installation Quality
To operate at maximum efficiency and comfort, your furnace must be correctly sized for your home. When it comes to furnaces, bigger is certainly 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 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 purchasing a new furnace. Even if it’s the correct size but installed wrong, 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 improperly designed, you might have problems with sound or comfort. A furnace is only as effective 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 kinds of home comfort systems. Besides technical skill, our technicians are also trained in treating you fairly. We also stand behind our work with a 100% satisfaction guarantee for a year.*
2. Energy Efficiency
Furnaces are ranked 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 higher the number, the less gas is wasted during the heating process.
If your present 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 wasting 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 research new furnaces there is one more important consideration: blower technology. This part moves air throughout your home. And it also consumes a lot of electricity, so it’s important to be familiar with your options.
There are three types 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 costly 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 operating at full speed 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 dramatic 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 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, particularly if your schedule changes from day to day.
A smart thermostat removes 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 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 keep tabs on and adjust 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 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 stand by its product warranty over the long term.
Furnaces usually have two main warranty coverage areas:
- Heat exchanger. This is the center of the furnace and the costliest 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 involves the blower motor, electronic controls, ignitors and other key parts. Warranties can vary from as little as a one-year limited warranty to as long 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 instance, nearly all standard manufacturer warranties only cover the price 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 reduce 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 anyhow? 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 affect on your budget, keep in mind 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.
- 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 company. 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 look for in a new furnace, when should you replace your old one? Here are a few tips from our Experts that will help you decide.
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 desired temperature. If you’re somewhere 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 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 price of a new furnace, it’s generally best to replace it.
Furnaces older than 15 years can be very inefficient. You could be throwing away as much as 30% of the money you spend to heat your home. 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 reduce their energy bills.
