Purchasing a new furnace may not be a priority in the immediate future. 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 consider when you're due for furnace replacement in Calgary.
1. Size and Installation Quality
To operate at maximum efficiency and comfort, your furnace must be properly sized for your home. When it involves furnaces, bigger is definitely not better. We often get requests from customers to install a big furnace in the mistaken belief that a larger furnace is either more dependable or will provide better comfort.
The reverse is true. Large furnaces will short cycle, or continuously turn on and off. This leaves you uncomfortable, with more expensive 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 installed wrong, 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 sound 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 kinds of home comfort systems. In addition to technical skill, our technicians are also trained in treating you ethically. We also support our work with a 100% satisfaction guarantee for a year.*
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 higher the number, the less gas is spent 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 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—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 moves 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 today. They include:
- Standard blower motor. Furnaces that aren’t ENERGY STAR rated have a traditional 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 cost and energy efficiency. It provides an electrical efficiency boost over a standard motor design.
- Variable-speed motor. The most energy-efficient furnaces can operate at different speeds. Instead of running at full blast 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 dramatic improvement has been keeping noise under control. Some of these features include:
- Sealed and insulated cabinets
- Variable-speed blower technology
- Nearly silent 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 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 pick up on 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 necessary.
As an extra perk, 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 change your air filter.
There’s a significant difference in furnace quality and reliability. Like any big purchase, we think it’s best 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 haul.
Furnaces usually have two primary warranty coverage areas:
- Heat exchanger. This is the heart of the furnace and the most expensive component to replace. This part usually has a 20-year limited warranty or lifetime limited warranty, but this can vary based on the manufacturer and furnace model.
- Main parts. 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 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 get the restrictions. For instance, 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 running, make sure you complete the product registration immediately. Many manufacturers may limit the warranty term if the product registration is not done. This step is simple and usually 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 think about these costs and the impact to 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 additional ways to save include:
- Getting a new air conditioner simultaneously.
- 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 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 look for in a new furnace, when should you replace your old one? Here are a few ideas 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 somewhere with harsh winters, your furnace will operate more frequently, potentially making it wear out sooner. The same applies if you like to keep your home at a hotter temperature.
Repair Frequency and Cost
Just like any appliance, as furnaces get older, the potential 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 more than the half the price of a new furnace, it’s generally best to replace it.
Furnaces older than 15 years can be extremely inefficient. You could be wasting as much as 30% of the money you spend to keep your home warm. High 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 reveals nearly 20% of homeowners who recently replaced their furnace specifically did so to lower their utility bills.
