WHAT DOES AFUE STAND FOR?
Annual Fuel Utilization Efficiency
HOW IS AFUE MEASURED?
AFUE measures a gas furnace’s efficiency in converting fuel to energy. A furnace that has an 80 percent AFUE rating can turn 80 percent of the energy it consumes into heat. The other 20 percent is used during the heating process.
WHAT IS A GOOD AFUE?
A higher AFUE rating means greater energy efficiency. The minimum standard AFUE for new furnaces is 78 percent. A mid-efficiency furnace usually has an AFUE rating between 80 and 85 percent, while a high-efficiency unit has a rating between 90 and 97 percent.
Now that you know what A.F.U.E. means and you want to check out getting some rebates for replacing your existing heating equipment, ask yourself the following questions:
How can I receive a rebate for switching your current gas furnace to a higher efficiency gas furnace?

As you may be able to see from the picture, a dog chewed into the bottom of this return air plenum which is located in the garage. The furnace being located in a garage area is very common, the furnace platform or return air platform/plenum in this case is one piece. So the outdoor air that is in the garage area is being pulled into the heating and cooling system. Then the heating and cooling system must heat or cool the outdoor air, not the conditioned air in the home. And this my friends is not good!
Your heating and cooling system is now responsible for heating and cooling conditioned air that it has conditioned in addition to outdoor air. This system will never keep you comfortable! So, check those HVAC units that are located in the garage. You never know what they have been subjected too in the past few weeks or months and may need to be repaired. Check them especially if you are having system performance problems or concerns.
Pets, bicycles, lawn mowers, cars and really any moving object can penetrate the old sheet rock casings for older systems. And penetrations are bad!
Call A.I.R. Plus if you need help with your system. We would love to help you!
Have a blessed day!
Natural Gas or Propane Furnace Carbon Monoxide Poison! How dangerous is it?
Read the following from Oklahoma Natural Gas Co.
About Carbon Monoxide
Natural gas is safe, clean and reliable. When appliances are installed properly and operating efficiently, natural gas burns cleanly, with little residue. However, if your natural gas appliance produces a yellow flame instead of a blue flame, it is not operating efficiently or is not vented properly. Carbon monoxide can be produced under these conditions.
Carbon monoxide (CO) is poisonous. CO is an odorless, colorless and tasteless gas that can make you sick or, under some circumstances, cause death. Carbon monoxide occurs when fuel does not burn completely. To avoid CO hazards, make sure your appliances are properly installed, cleaned, maintained and vented.
The sources of carbon monoxide can include improperly vented cooking and water heating appliances, auto exhaust, blocked chimney flues and malfunctioning fuel-burning appliances.
Indications that carbon monoxide may be present in your home or building include the following:
- Black soot on or near registers, flues, furnace filters, burners or appliance access openings;
- Condensation on windows or interior walls (condensation on widows can also be caused by humidifiers or vaporizers);
- A yellow flame (instead of a blue flame) on appliance burners;
- Recent death of a pet, unexplained illness or dead or dying houseplants;
- Absence of draft in your chimney.
Look for symptoms of carbon monoxide poisoning. Always be alert to the possibility of exposure to carbon monoxide. Learn to recognize the following symptoms of carbon monoxide poisoning.
- Initially, carbon monoxide poisoning can cause flu-like symptoms, including headache, dizziness, ringing in the ears, fatigue, increased perspiration, nausea, weakness and vomiting.
- As carbon monoxide levels increase, symptoms may become more severe and include shortness of breath, extreme muscular weakness, intermittent convulsions, mental confusion and unconsciousness.
- Severe poisoning can cause such symptoms as change in skin color to pink, lips and mucous membranes change in color to cherry red, and heart and lung failure.
What to do if you suspect carbon monoxide poisoning:
- Immediately leave the building. Call 911 from a neighbor’s phone or call your local fire or police department. Or call Oklahoma Natural Gas at 1-800-458-4251.
- Do not re-enter the building until it has been determined safe by emergency response personnel.
- Immediately seek medical assistance for any symptoms, even those you think are minor.
- Make certain your appliances are operating properly, no matter what type of fuel you use.
- Check and maintain proper ventilation of the flue and chimney.
- Have a qualified heating and cooling contractor inspect your gas furnace annually.
- If you see a yellow furnace flame instead of a blue one, it’s a warning sign that your appliance is not operating properly. Call a qualified heating and cooling contractor to inspect your furnace immediately.
- Clean or replace heating system air filters regularly.
- Do not block air intake areas near or around appliances.
- Do not use a natural gas range or space heater to heat your home.
- Do not start your car, lawn mower, snow blower or any combustion engine in a closed garage.
- Do not operate your grill inside an enclosed area.
Carbon Monoxide Detectors
Carbon monoxide detectors can alert you to the presence of carbon monoxide. If you install a detector, follow the manufacturer’s directions regarding installation.
DO NOT place a detector in any of the following locations:
- Places where the temperature may drop below 40 degrees F
- Near paint or paint thinner fumes
- In the kitchen or within five feet of open flames from appliances
- Near vents, flues or chimneys
Know the sound your detector makes when it goes off. Be able to tell the difference between your carbon monoxide detector and your smoke detector.

Flexible Duct Piping has been commonly used for over 30 years in residential and commercial HVAC applications and in ductwork setups. However, just like most man made things – they wear out and break down and are no longer doing what they were originally designed to do!
If you see duct work piping in your home or business, that looks like the attached pictures. You are wasting money in heating or cooling the space the duct work is set-up in.
When you have your Heating and Cooling System serviced and or replaced, make a point to ask your HVAC Contractor what the condition of your duct work is and to provide pictures. You maybe surprised at the condition, especially if its over 20 years old!
Call 405-618-2247 and allow us to give you an evaluation of your Duct Work System. We will give you information, feedback and suggestions for resolution of your comfort concerns and energy efficiency. Or go to airokc.com for additional information.
