7 Things to Be Aware of Before Purchasing a Furnace in London

Buying a new furnace may not be a concern right away. But it’s wise to know the things that will likely impact your choice when you’re ready to buy. Here are seven things you’ll want to think about when it’s time for furnace replacement in London.

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 certainly not better. We frequently get requests from customers to install a big furnace in the mistaken belief that a larger furnace is either more reliable or will offer better comfort.

The opposite is true. Oversized furnaces will short cycle, or constantly turn on and off. This leaves you cold, with more expensive energy bills and a furnace that could wear out much sooner.

This is why it’s crucial to work with the right company when purchasing a new furnace. Even if it’s the correct 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 effective as the duct system it’s linked to.

2. Energy Efficiency

Furnaces are rated 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 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 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 research new furnaces there is one more important thing to consider: blower technology. This part circulates air throughout your home. And it also consumes 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 traditional blower motor that’s been relatively 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 price and energy efficiency. It provides an electrical efficiency boost over a traditional motor design.
  • Variable-speed motor. The most energy-efficient furnaces can operate at different speeds. Instead of running 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 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 on.

5. Smart Thermostat

You probably have a programmable thermostat, but it's quite possible 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 removes all the guessing about energy efficiency. Many models can learn from your temperature preferences and then produce an energy-saving schedule to match. They also know when you’re home or away and will adjust your heating and cooling as needed.

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 alert you if they detect a problem with your furnace or remind you when it’s time to change 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 confidence in the technology and that the manufacturer will stand by 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 limitations. For instance, nearly all standard manufacturer warranties only include the price of the replacement part, not labor. And labor on a replacing heat exchanger could get costly.

Once your new furnace is installed, make sure you finish the product registration right away. Many manufacturers may limit the warranty term if the product registration is not done. This step is easy and typically 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 model.

As you consider 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.
  • Buying 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.
  • Take advantage 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 ideas from our Experts that will help you make that decision.

Age

Heating systems usually last 15–20 years. How long yours will last depends on whether you’ve kept up with furnace maintenance, where you live and your temperature preferences. If you’re somewhere with harsh winters, your furnace will operate more often, potentially making it wear out faster. 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 increases. If your system is more than 15 years old, those repairs can be especially 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 very inefficient. You could be throwing away as much as 30% of the money you spend to heat your home. High energy costs and the desire to decrease energy consumption are also strong reasons to consider 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 utility bills.
