Furnace Blower Fan on 100% of the time - Good or Bad or it depends? I was at a dinner party last night and two guests described how their HVAC reps told them to run their furnace blowers 100% of the time.  The HVAC reps reasons for the recommendation, as relayed by the dinner guests, were: I've found most blower motor failures are due to unbalanced blower wheels (bearings go bad) or overheating (windings burn up). Both caused by excess dirt in motor/blower wheel. Thanks for giving your furnace/motor experience John. One issue I have with the 100% furnace fan run-time is that it does not provide 'fresh air' but recirculates the indoor air. This practice would certainly require a increase in air filter replacement. And yes seems to me to be an energy waster. Anyone hear the argument that motor start up amps are huge when cycling, so better to leave the motor running and you could 'save energy'? Sounds like a similar argument we've heard about lighting. Any electricians want to chime in on this one?

Thanks for commenting and offering your experience. I'm with you about constantly learning something new. It's never ending in our fields! I also agree with you about poor duct design and installation. It is a root problem for many issues seen. As for running the fan on 'auto' or continuously 'on', from an energy perspective I tend to believe that 'auto' would be more energy efficient over time regardless of whether an individual fan is variable or not (I'm not comparing a variable speed vs a conventional motor here just the fan setting). Wisconsin's Focus on Energy recommends setting fans to 'auto', see link here. They offer commentary on common assumptions about running blower fans continuously. But Focus on Energy's take contradicts what my friends were told by their HVAC reps. Focus on Energy's assumption #3 really speaks to your point that running the fan for temperature stability really masks other issues such as poor duct design, leaky envelope areas, inadequate insulation, etc.

This is just plain wrong. Standard furnace blowers use about 500 Watts and setting them to "ON" for the whole year vs. AUTO wastes about 3,000 kWh/yr. This is a tremendous waste of energy. In addition, in cooling season the fan adds significant heat to the home directly and indirectly if the ducts run outside the conditioned space.Electricity usage of a Ceiling Fan A ceiling fan is a common house appliance which is attached to the ceiling and uses an electric motor to rotate blades or paddles in a circular motion. Ceiling fans help cool a room by moving air which causes evaporative cooling. Fans range in size from 36 inches to 56 inches using 55 to 100 watts, a typical 48 inch ceiling fan will use 75 watts. Click calculate to find the energy consumption of a 48 inch ceiling fan using 75 Watts for 3 hours a day @ $0.10 per kWh. Hours Used Per Day: Hours Used Per Day: Enter how many hours the device is being used on average per day, if the power consumption is lower than 1 hour per day enter as a decimal.

(For example: 30 minutes per day is 0.5) Power Use (Watts): Enter the average power consumption of the device in watts.air handling units nz Price (kWh): Enter the cost you are paying on average per kilowatt hour, our caculators use the default value of 0.10 or 10 cents. air handling unit maintenance pdfTo find an exact price check your electricity bill or take a look at Global Electricity Prices.ac unit base pads A ceiling fan is far cheaper to run than an air conditioner, if you are comfortable with using fans to cool yourself during hot weather then you will be able to save energy and money. Ceiling fans do not cool the air in the room, if you are not in a room turn off the ceiling fan. The reason why a room feels cooler when the fan is on is because moving air causes water to evaporate from the surface of your body which makes you feel cooler.

Las Vegas was founded three years later. Actually, our first air-conditioned building was the El Portal Theater at 310 Fremont Street, which debuted its coolness on June 21, 1928. If we were to have a citywide holiday, that should be it. About 65 percent of the average power bill in Las Vegas during summer months is a direct result of AC use. The recommended thermostat setting is 78 degrees, according to Pam Hilts, manager of residential programs at NV Energy. (She keeps her home at 83.) Every degree you lower the thermostat increases your bill by 2.5 percent. So, by going from 76 degrees to 78, you can save 5 percent. Ceiling fans don’t really cool off a room—just the people in it.

In other words, a fan blowing in an empty room doesn’t directly add any efficiency, but it may keep you from lowering your AC to be comfortable. Run major appliances in the evening, so as to not make your AC work any harder than it has to in the daytime. The mPowered program is a pretty cool deal. Pick a technician, who comes to your home and installs a smart thermostat, which you’ll be able to adjust remotely via smartphone or online. It’s all free, and you’ll save money on your power bill by not cooling your home as often. The thermostats allow you to reduce the electric load at a time when energy costs are higher, allowing NV Energy to more cost-effectively meet peak demand. The credits you earn from saving the energy company energy are applied to your account at the end of the year. Hardware stores also have smart thermostats, which are likely better than the ones that came with your house. They let you schedule times for higher set points when no one is home and then cool off before you arrive.

Some can even tell when filters need to be replaced. The average AC unit lasts 15-20 years. The condensing fan motor goes out every five to 10 years, thanks to our intense heat. And it’s expensive to replace (more than $400, for an average-size unit). It can last twice as long if it’s in the shade, though. You can get your units inspected every year, but that may be overkill if you’re taking good care of them. The best way to take care of your units is to change the air filters (they reside in the air-return vents in your house) every 30 days—or 90 days, if they’re high-quality, pleated filters. Also: Hose off your outdoor condensing units once a year to get rid of the dust and debris, which can hamper efficiency. While you’re at it, make sure there is nothing (such as bushes and weeds) within about 2 feet of the condenser that might impede the airflow. The air-filter debate: One AC contractor we talked to said there really aren’t any residential units that can handle the high-quality, pleated variety because they’re denser than the standard fiberglass filters.
