When choosing a new furnace, find out its “AFUE” –Annual Fuel Utilization Efficiency. It’s a term for describing a furnace’s seasonal energy performance. Why should you care about the AFUE? Given the rise in energy prices and uncertainty about future energy sources, minimizing energy bills is so important. High-efficiency heating systems use less energy, lowering your monthly costs. By federal standards, new furnaces must have an AFUE rating of at least 78%.
Is Your Furnace Correctly Sized?
An over-sized furnace — one whose capacity is too large — costs more to operate than a correctly sized furnace. This is because over-sized furnaces “Short-Cycle,” that is cycle on and off too quickly and too often, which is more expensive and much less energy efficient than running consistently for a longer periods of time. If your furnace has a variable speed circulating fan blower motor, you will save even more because of this important efficiency detail.
The only way to know if your furnace is correctly sized is for your heat and air conditioning contractor to do a load calculation. A load calculation takes into account the size of your house, the insulation value of your windows, the amount of insulation in your walls and roof, and a host of other criteria to determine the appropriate furnace capacity.
Ask your heating contractor if he performed a load calculation before you accept the furnace they recommended. If you are replacing an old furnace (as opposed to buying a furnace for new construction) some contractors may argue that you should simply buy a furnace that’s as large as your previous furnace, but this assumes that the previous heating contractor selected an appropriately sized furnace and doesn’t take into account differences in AFUE (Efficiency) and furnace blower motor strengths. The fact is you will be able to use a 90,000 BTU 95% AFUE Gas Furnace, where you used to use an 80% AFUE Gas Furnace….. That is going to be huge savings! The kind of savings that return the cost of the new furnace to you over 3-5 years (Round down if you have insulated duct work, where needed.)
How do you use Furnace Ratings when buying a furnace?
Normally, when a homeowner is in the market for a furnace, a major purchase, the sensible thing to do is check furnace ratings. Homeowners must understand how furnace ratings work before they can consider them. Efficiency ratings help consumers determine which furnace will be cheaper to run.

Basically, there are three (3) types of furnace efficiency ratings that homeowners should consider:
Consumer or Customer Satisfaction Ratings
However, quality ratings are not available for furnaces. Not even Consumer Reports performs quality ratings for furnaces, so the bulk of your decision must be based on efficiency ratings and customer satisfaction ratings. Combined, the two ratings can help you make the right purchasing decision for your home and family’s heating needs.
Furnace Efficiency Ratings – What Are They?
There are three (3) types of Furnace Efficiency Ratings:
Annual Fuel Utilization Efficiency (AFUE)
The percentage of energy that is converted to warm air in your home. A 95% AFUE rating means 95 cents of each energy dollar spent actually produced heat. 95% AFUE Furnaces have become very affordable!
The easily recognizable black and yellow label, developed by the Federal Trade Commission, helps you to determine how energy efficient an appliance is and how the appliance will affect your utility bill.
The designation that goes to the most energy efficient appliance in each class. Appliances with the Energy Star logo must meet or exceed federal energy-use standards.
Air Filters and Your Furnace
The filter on a forced-air furnace performs a valuable function in the home. It strains bits of dust, dirt and debris from the air stream as it passes through the furnace. This not only improves air quality, but it also protects the inside of the furnace (and air-conditioning evaporator coil, if there is one). Without a furnace filter in place, dirt will build up on the back side of the heat exchanger and inside the evaporator coil. That dirt acts as insulation and interferes with the efficient transfer of heat from the furnace or cooling from the air conditioner to the air passing through it.
A furnace filter also slows the passage of air through the furnace, especially when it is dirty. The best way to keep your furnace operating at its maximum efficiency is to keep a clean filter inside. That is one of the only things you as a homeowner can do to maintain your gas furnace or electric furnace.
Filters can be purchased in bulk on the internet. HVAC Filters should replaced every 30 to 45 days, or they can be vacuumed at those same time intervals. People who own pets may find that their furnace filters need to be replaced or cleaned more frequently, due to pet dander, hair, and dirt brought in from outside.
It is important to remember that in most homes that have a central air-conditioning system, the furnace’s blower is used to distribute cool and dehumidified air during the summer months. Therefore, air passes through the furnace and the furnace filter as well during those months as well. That’s why homeowners with central air-conditioning systems need to change or clean filters in the summertime at roughly the same intervals as they do during the winter. The more freely air can pass through the furnace, the more heat and cooling it can distribute while wasting less energy.
If your furnace was built before 1992 and has a standing pilot, it probably wastes 35 percent of the fuel it uses, and it is probably very close to the end of its service life. In this case, in all but the warmest climates, current recommendations are for early replacement with a condensing furnace with annual efficiency of at least 90 percent. This type of furnace wastes no more than 10 percent of the natural gas you buy, and may save you as much as 27 percent on your heating bill.
If your furnace was installed after 1991, it probably has an annual fuel utilization efficiency (AFUE) rating of 80 percent, so the savings from replacement is smaller, but would be at least 11 percent if the unit is working perfectly. Your heating service technician or energy auditor may be able to help you determine the AFUE of your present system.
For houses with boilers and hot-water heat distribution (radiators, baseboard), the savings from a modern condensing boiler with outdoor reset or equivalent feedback controls can be substantially larger, since the condensing boilers allow reducing the circulating loop temperature almost all the time.
To ensure maximum airflow, make sure you keep all vents and air registers clear of obstructions like shoes, furniture and drapes. This will help you get heat to all corners of your rooms as efficiently as possible. To improve airflow further, use a ceiling fan spinning clockwise to move warm air from the ceiling all around the room.
