Choosing the right furnace for your home is a major decision that affects your comfort, your energy bills, and your family’s safety. If you’re planning a new furnace installation, understanding furnace efficiency ratings is essential to making an informed choice.
In this article, we’ll explain what furnace efficiency ratings are, why they matter, and what to consider when buying a high-efficiency furnace for Calgary heating needs.
What Are Furnace Efficiency Ratings?
Furnace efficiency ratings measure how effectively a furnace converts fuel into heat. The main rating you need to understand is the AFUE rating (Annual Fuel Utilization Efficiency).
AFUE is expressed as a percentage. It tells you how much fuel energy is actually converted into heat for your home. For example, a furnace with an AFUE rating of 95% means that 95% of the fuel becomes heat, while only 5% is wasted.
In older furnaces, you might see AFUE ratings around 60% to 70%. Modern high-efficiency furnaces typically have ratings of 90% or higher.
Why Furnace Efficiency Ratings Matter
Higher furnace efficiency ratings directly impact your monthly utility bill. An efficient furnace uses less fuel to heat your home, lowering your energy bills over time. With Calgary’s long, cold winters, a high-efficiency furnace can lead to significant savings.
In addition to cost savings, an efficient furnace also reduces your carbon footprint and helps minimize the risk of carbon monoxide leaks from incomplete combustion.
Comparing Furnace Models: Key Features to Look For
When shopping for a new furnace, you’ll encounter many different furnace models. Pay close attention to these features:
AFUE Rating: Look for furnaces with at least a 90% AFUE rating for Calgary heating.
Variable Speed Blower: A variable speed blower adjusts airflow more precisely, improving efficiency and home comfort.
Heat Exchanger Quality: A high-quality heat exchanger is vital for transferring heat efficiently and safely.
Type of Furnace: Decide between natural gas, electric furnaces, or oil furnaces based on your home’s needs and energy prices in Calgary.
Energy Star Certification: Energy Star-rated furnaces meet strict energy efficiency standards.
If you also use air conditioning or are considering heat pumps, make sure your HVAC services provider checks for compatibility when recommending furnace models.
High-Efficiency Furnace vs. Older Furnace
The furnace cost upfront for a high-efficiency model may be higher, but the savings on energy bills can quickly make up the difference. In contrast, an older furnace with a low AFUE rating will cost more to operate and may be more prone to breakdowns, increasing furnace repair costs.
Plus, a high-efficiency furnace often delivers better airflow and consistent heating, improving your overall home comfort.
Factors That Affect Installation Costs
New furnace installation isn’t just about the unit price. Installation costs can vary depending on:
The complexity of the job
Whether new ductwork or venting is needed
The furnace brand and model selected
Upgrades like programmable thermostats
Getting professional HVAC services ensures your new furnace is properly installed and running safely and efficiently.
Is It Time for Furnace Replacement?
If you’re noticing higher energy bills, uneven heating, frequent furnace repair needs, or your system is more than 15 years old, it might be time to consider furnace replacement. Investing in a high-efficiency furnace now can lead to lower heating costs and fewer headaches later.
Want Lower Energy Bills ?
Understanding furnace efficiency ratings is key to choosing a system that will efficiently and affordably heat your home for years to come. Calgary homeowners benefit greatly from investing in a high-efficiency furnace, both through lower energy bills and improved home comfort.
Before buying your next unit, compare AFUE ratings, think about furnace brand reputation, and work with trusted HVAC services to ensure a smooth installation process. Making the right choice now means you’ll stay warm and save money every winter.
FAQ: Furnace Efficiency and Buying Tips
What is a good AFUE rating for a new furnace?
Aim for a furnace with an AFUE rating of at least 90%. High-efficiency furnaces often have ratings between 92% and 98%.
Are electric furnaces more efficient than gas furnaces?
A: Electric furnaces can have 100% AFUE ratings, but natural gas furnaces are often cheaper to operate in Calgary due to lower fuel costs.
How long does a high-efficiency furnace last?
With regular maintenance, a high-efficiency furnace can last 15 to 20 years or more.
Should I replace my air conditioning system when getting a new furnace?
A: If your AC is also aging or incompatible with modern furnaces, it might be cost-effective to upgrade both at the same time.
What should I ask before furnace installation?
A: Ask about furnace cost, efficiency ratings, warranty options, and whether installation costs cover any necessary updates to ductwork or vents.
