7 Things to Be Aware of Before Buying a Furnace in Jacksonville

Purchasing a new furnace may not be a priority right away. But it’s smart to know 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 it’s time for furnace replacement in the U.S.

1. Size and Installation Quality 

To operate at peak efficiency and comfort, your furnace must be properly sized for your home. When it comes to furnaces, bigger is certainly not better. We frequently get requests from customers to install a big furnace in the misguided belief that a larger furnace is either more dependable or will offer 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 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 key component of installation is ductwork. If yours is old or designed wrong, you might have issues with noise or comfort. A furnace is only as effective as the duct system it’s attached to. 

At Service Experts Heating, Air Conditioning & Plumbing, our Expert HVAC technicians are ACE certified, which means they’re skilled in repairing and installing various kinds 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 rated 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 greater the number, the less gas is wasted during the heating process. 

If your present 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 wasting 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 research new furnaces there is one more important consideration: blower technology. This part moves air throughout your home. And it also uses a lot of electricity, so it’s essential 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 mostly unchanged for the past 30 years. This motor is the least costly 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 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 operate 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 significant consideration with furnace installation, so another great improvement has been keeping noise under control. 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 running. 

5. Smart Thermostat 

You probably have a programmable thermostat, but chances are you probably aren’t making the most of your energy savings. These thermostats can be difficult to program, particularly if your schedule changes 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 necessary. 

As a bonus, 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 find a problem with your furnace or remind you when it’s time to replace your air filter. 

6. Warranty 

There’s a significant 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 assurance in the technology and that the manufacturer will stand by its product warranty over the long term. 

Furnaces usually have two primary warranty coverage areas: 

  • Heat exchanger. This is the center 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 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 going over warranty coverage, it’s essential to know it’s limited. So, you should make sure you understand the restrictions. For example, 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 finish the product registration right away. Many manufacturers may reduce the warranty term if the product registration is not completed. This step is simple and usually only takes a few minutes. 

7. Cost 

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 system. 

As you think about these costs and the affect on your budget, keep in mind 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 offers. 

A couple of other ways to save include: 

  • Replacing your air conditioner simultaneously. 
  • Purchasing at the right time, such as in early fall, mid-winter and early spring. You may be able to get additional 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 figure out 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 make that decision. 

Age 

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 operate 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 get older, the likelihood for frequent furnace repair goes up. If your system is more than 15 years old, those repairs can be particularly 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. 

Energy Efficiency 

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 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 reduce their energy bills.
