Buying a new furnace may not be a priority in the immediate future. But it’s wise to know the things that will likely impact your selection when you’re ready to buy. Here are seven things you’ll want to consider when you're due for furnace replacement in Columbus.
1. Size and Installation Quality
To run at peak efficiency and comfort, your furnace must be properly sized for your home. When it involves furnaces, bigger is definitely not better. We frequently get requests from customers to install a big furnace in the misguided belief that a larger furnace is either more reliable or will provide better comfort.
The opposite is true. Large furnaces will short cycle, or constantly turn on and off. This leaves you cold, with higher 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 right size but improperly installed, the U.S. Department of Energy says you could lose as much as 30% of your energy efficiency.
Another crucial component of installation is ductwork. If yours is old or improperly designed, you might have issues with noise or comfort. A furnace is only as good as the duct system it’s linked to.
At Service Experts Heating & Air Conditioning, our Expert HVAC technicians are ACE certified, which means they’re skilled in repairing and installing various types of home comfort systems. In addition to 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 ranked by a term known as 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 wasted 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 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 compare 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 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 relatively 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 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 blast 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 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
- Whisper-quiet gas burners
With this technology, you might not even notice 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 varies from day to day.
A smart thermostat eliminates all the guessing about energy efficiency. Many models can pick up on your temperature preferences and then produce 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 find 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 large purchase, we believe it’s wisest 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 stand by its product warranty over the long term.
Furnaces typically have two primary 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 components. This involves the blower motor, electronic controls, ignitors and other important parts. Warranties can range from as little 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 get the restrictions. 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 costly.
Once your new furnace is running, make sure you finish the product registration right away. Many manufacturers may limit the warranty term if the product registration is not completed. This step is easy and typically 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 system.
As you consider these costs and the impact to your budget, remember that unlike nearly every other appliance you may need to purchase, 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 receive 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 outdated 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 kept up with 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 potential for frequent furnace repair increases. If your system is more than 15 years old, those repairs can be especially costly. Common and costly repairs on an older furnace include:
- Blower motor failures
- Ignition control failures
- Heat exchanger failures
If repairs are greater than the half the cost 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 keep your home warm. High energy costs and the desire to decrease energy consumption are also strong reasons to think about 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 lower their utility bills.
