User-friendly thermostats pay off in energy savings

Posted by Newbie Bloggers on Wednesday, 1 August 2012


Nearly half the money you spend on home energy goes to heating and cooling. For the average household that's about $1,100 a year. A programmable thermostat can save you money by automatically reducing heating or cooling when you need it least. The thermostat has to be properly set, of course, and our latest tests of 30 models reveal that many are now much easier to use.

That wasn't always the case. Energy Star stopped certifying thermostats in late 2009 mostly because they were so hard to use and could lead to wasted energy. Energy Star is developing new standards that include ease of use, but in the meantime you'll find models in our new thermostat Ratings that are very simple to use with screens that are easy to see. Most models accurately maintained temperature settings within one to two degrees so our thermostat tests focus on ease of use based on our panelists ability to set them up and make routine adjustments before reading the manual and then with the manual if needed.

And here's the really cool part. The top three thermostats, like the Venstar ColorTouch Series T5800, $170, have interactive displays and color screens. Some allow you to monitor energy use and make changes via your smart phone or laptop while you're off trotting the globe. The $250 Nest Learning Thermostat can be programmed remotely. It's unlike any thermostat we tested in form or function and a recommended model. It's round and sleek, with a rim dial for making adjustments, and a techie's dream. You can program it yourself or let it automatically program itself based on changes you make the first week. It notes your preferences and schedules and keeps on making adjustments. Pretty cool. And that's the whole idea.

Dirty air conditioner filters can make you lose your cool

Posted by Newbie Bloggers on Friday, 20 July 2012


As the summer heat continues unabated, it's a good time to make sure you're getting the most out of your air conditioner and dehumidifier. One easy way is to clean the filters. If you haven't done so since summer began, then this chore is long overdue. The improved performance of your appliances will make you glad you made the effort.

Dirty filters hamper the efficiency of your air conditioner and dehumidifier. And if they're working harder, it's costing you money without making your home more comfortable. If you have central air conditioning, have your contractor show you how to change the filters. During cooling season, Energy Star recommends that the filters be inspected, cleaned or changed every month. Alternatively, if you feel like your system is losing its oomph, have a licensed professional change all filters; clean and flush the coils, drain pan, and drainage system; vacuum the blower compartments; and check the refrigerant and mechanical components.

With window air conditioners, some filters are easier to change than others. Cleaning may be needed every few weeks during the hottest part of the summer. With that in mind, make sure you determine how easy it is to remove the filter when selecting a new unit. When cleaning it, remove debris with a vacuum then wash the filter in warm, soapy water; be sure filters are dry before you reinstall them and replace damaged filters.

When the filter is removed for cleaning, check the surface of the evaporator coil, which will now be visible. If there is dust or debris on the surface, gently remove it. Taking care not to deform the soft fins, use an upholstery-brush attachment to vacuum the coils.

Dirty filters can also inhibit the performance of your dehumidifier. Most can be easily removed and cleaned in just a few minutes. Don't neglect this task just because your unit is out of sight in the basement. Keeping the filters clean will improve the air quality and keep your machine working at its best. This is important when the humidity is high.
