On frigid days, your heating system is essential for maintaining a comfortable home environment. By ensuring consistent warmth indoors, your furnace shields your family from cold-related health risks and helps safeguard your plumbing by reducing the chance of frozen pipes during winter.
The ideal heating system should be efficient, operate quietly, and last for years. An energy efficient heater delivers advantages like lowering utility bills, spreading heat evenly, and minimizing upkeep costs.
In this article from PFO Heating & Air Conditioning, we highlight three key signs that reveal whether your heater is efficient and share practical tips for boosting your system’s overall performance.

Identifying an Energy-Efficient Heater
Contents
Before investing in a heating system, it is essential to calculate your home’s total square footage. Doing so helps you select a unit with the proper heating capacity, ensuring it can keep your home comfortable without wasting energy.
The U.S. Department of Energy (DOE) states that older heating systems generally operate at 56% to 70% efficiency, while newer models can reach as high as 98.5%. However, without proper upkeep, a system’s efficiency can decline by as much as 5% each year.
Below are three critical indicators that can help you determine if your heating system is performing efficiently.

1. Heater Age
Most home heating systems last between 15 and 20 years. Even with regular professional care, efficiency gradually declines over time as components experience normal wear. The age of your system often reflects its efficiency, with older units typically performing at lower levels compared to newer ones.
If you are uncertain about your heater’s efficiency despite knowing how old it is, scheduling an inspection with a licensed HVAC contractor can provide a clear assessment.
2. Utility Costs
Energy bills naturally vary by season based on heating demand. However, your total yearly costs should remain relatively consistent with the previous year unless the price per unit of energy has increased. With all other factors being equal, reviewing your bills from the same period last year can reveal whether there has been an unusual rise in heating expenses that may point to reduced efficiency.
A noticeable increase in energy bills may signal that your heating system is losing efficiency. When a unit is less efficient, it must run longer and harder to maintain the desired temperature. This extra effort increases energy usage, ultimately driving up your heating costs.

3. AFUE Rating
The Annual Fuel Utilization Efficiency ratio, commonly referred to as AFUE, is the standard measure used to show how efficient a heating system is. This rating is determined by dividing the total heat produced by the total amount of fuel consumed, essentially comparing heat output against heat input. For example, a heater with a 95% AFUE rating is capable of converting 95% of its fuel supply into usable heat, while the remaining 5% escapes through the venting system as wasted energy.
In most cases, manufacturers include the AFUE rating directly on the labels of heating systems. This allows homeowners to quickly determine how efficient their unit is by simply reviewing the label to see if it is still intact.
If the label is missing, you can locate the model or serial number of the heater and use that information to look up the AFUE rating on the manufacturer’s website. By checking this rating, you can easily evaluate whether your heating system is operating at an efficient level.
Ways to Enhance Heating System Efficiency
An inefficient heater can compromise indoor comfort during cold weather, drive up energy expenses, and experience more frequent breakdowns. The type of fuel used can also play a role, as low-efficiency systems tend to contribute more to carbon emissions. Keeping this in perspective, consider the following tips to help improve the efficiency of your heating system.
- Replace and Clean HVAC Filters: When filters are clogged, your furnace must work harder to circulate air. Cleaning them regularly and replacing them as needed helps maintain efficiency and keeps airflow steady.
- Improve Home Insulation: Proper insulation keeps more heat inside your living space, easing the workload on your heating system and helping it run more efficiently.
- Book Yearly Heating System Checkups: Routine professional inspections allow an HVAC contractor to identify and correct issues early. This care enhances efficiency and extends the system’s performance.
- Install a Programmable Thermostat: Programmable thermostats reduce unnecessary operation by automatically adjusting based on your heating needs. They ensure your furnace uses only the fuel required to maintain desired comfort levels.

Reasons to Upgrade an Old Heating System
There comes a point when routine maintenance is no longer enough to restore efficiency in an aging heater. When that happens, replacing the unit becomes the better option, offering several advantages:
- Enhanced Comfort: Modern heating systems are designed with higher efficiency and can warm your home more effectively. During the coldest days, reliable and consistent heat is essential, which older systems often struggle to provide.
- Fewer Breakdowns: Wear and tear in older heaters leads to frequent malfunctions. By installing a new unit, you can reduce unexpected breakdowns and cut down on costly repairs.
- Lower Energy Expenses: New heaters are built to operate efficiently, which helps reduce energy usage. This improved efficiency directly translates into savings on your heating bills.

Heating Efficiency FAQs
Is Age Enough to Measure a Heater’s Efficiency?
Although age is an important factor, it is not the only measure of efficiency. Performance also depends on the system’s design, how well it was installed, and the level of regular care it has received. An older heater can still deliver efficient operation if it has been adequately maintained and fitted with updated parts.
What Steps Can I Take If the AFUE Rating Is Missing on My Heater?
If you cannot locate the AFUE rating on your unit, look for the model or serial number instead. With this information, you can search the manufacturer’s website or reach out to their customer support team to obtain accurate efficiency details. This method provides you with the exact performance data specific to your heating system.
Is There a Specific Energy Bill Level That Confirms Inefficiency?
There isn’t a universal benchmark that immediately points to inefficiency since energy expenses often shift due to different variables. Still, if you notice steady increases in your bills even when fuel prices and household usage remain unchanged, it may indicate your system is becoming less efficient. Tracking your energy costs over time is a reliable way to detect a gradual efficiency decline.

How Can I Tell If My Home Has Proper Insulation?
Good insulation usually shows through steady indoor temperatures and manageable heating expenses. If you experience drafts, uneven warmth across rooms, or your heating system running excessively, these are common indicators of poor insulation. Scheduling an energy audit can provide a thorough evaluation of your home’s insulation and highlight areas that need upgrades.
What Problems Can Arise from Using an Old Heater?
Relying on an outdated heating system can create several challenges. These include higher energy usage as the unit works harder to keep up with heating needs, frequent and costly repairs from worn components, and a greater chance of unexpected system failures.
In addition, older heaters may fall short of current safety codes, which can put your household at risk. Replacing an aging system with a newer, more efficient model improves safety, boosts comfort, and lowers long-term operating costs.
Conclusion
The efficiency of your heating system can be evaluated by considering its age, reviewing its AFUE rating, and monitoring your energy bills for unusual increases. If signs of inefficiency are present, it is best to have a professional HVAC technician carry out a detailed inspection and the necessary work to restore efficiency. In situations where the system is outdated or beyond repair, a full replacement may be the most practical solution.
