What Is the Energy Star Label?

Monday, June 6th, 2011

Any time you go out and buy any type of appliance, you probably notice that some have a distinct mark that signifies them as Energy Star appliances. That sounds like a good thing, of course, but what does it actually mean? Should you always buy an Energy Star model over another type?

The Energy Star label was originally developed to help consumers more easily recognize appliances that are more energy efficient than the average. In order to obtain an Energy Star seal of approval, any device must meet very strict guidelines when it comes to energy efficiency.

What that translates into for you as a consumer is a lower monthly energy bill when you buy Energy Star appliances. Of course, once they have obtained an Energy Star labels, manufacturers can charge whatever they want for their product, and it is not unusual to pay more for a model that is certified an Energy Star.

However, as long as the potential savings over time that you will get by using the Energy Star model as opposed to one that is not as energy efficient outweigh the difference in initial purchase price, it is worth it to spend a bit more on the Energy Star model.

Keep in mind, though, that just because a produce meets the Energy Star guidelines for energy efficiency does not necessarily mean that it is a superior product in terms of quality or overall effectiveness. Plus, not all Energy Star appliances are created equal. You should still do your research and pick out the product that will both save you the most money and has the best chance of getting the job done right.

Another benefit to Energy Star products is that, because they use less energy when they run, they also have a smaller impact on the environment than a model that uses a greater amount of energy to perform the same tasks.

Overall, it is definitely worth taking a closer look at all of the Energy Star options out there when you are purchasing an air conditioning system or any other type of appliance. Using less energy is always a good thing both for your bank account and for the planet. But you also want to make sure you are actually getting the best product for your money.

What Are Limit Switches and How Do They Work?

Friday, June 3rd, 2011

When you set the thermostat on your air conditioning system, you pretty take for granted that the system will maintain that temperature throughout your house. But did you ever stop to think about how it’s actually accomplished? The truth is that there are many moving parts that all play a role in keeping your home cool and comfortable, and one of these is the limit switch.

What Is a Limit Switch?

Although you’re probably not aware of it, you’ve encountered plenty of limit switches over the years. A limit switch is anything that stops an electric appliance under certain circumstances. The little switch that turns the light on in the refrigerator when you open the door and then off again when you close it is the perfect example of a limit switch. Another common one is the switch that stops your washer or dryer from running when you open the door. Limit switches are used for a variety of appliances and gadgets to not only save electricity but to keep you and your device safe.

Limit Switches and Air Conditioning

The limit switch on your air conditioning system is the link between the blower on your air handler and the thermostat. When the thermostat senses that the desired indoor temperature has been reached, it stops the air conditioner from producing any more cold air. At that point, it’s important for the blower to stop functioning as well.

If it doesn’t, the blower will continue to move and warm air rather than cold will begin circulating throughout your home. However, if the blower shuts off too soon, the cold air that’s still being generated by the air conditioner won’t be able to circulate. So it’s essential that the blower be switched off at the same time the cold air stops arriving. That’s exactly what the limit switch does.

While it’s only one very small part of a large machine, the limit switch in your air conditioner plays a vital role in keeping your home comfortable and in allowing your air conditioning system to function as efficiently as possible.

If you notice that your air conditioner is shutting off too soon or not soon enough, it may be because of a broken limit switch. Sometimes, the system simply needs to be reset, something you can do with the help of your owner’s manual. However, if your limit switch is broken, you should contact a professional to take a look and determine if it needs to be replaced.

A Different Way to Zone Your Heating

Wednesday, June 1st, 2011

One of the most frustrating things about traditional heating is that you must pay for the entire home to be heated. You flip on the thermostat and you get the same temperature for every room. Vent covers can reduce how much heat gets to each room, but if you want one room to be cooler than another, how do you do it without installing an expensive zone control system?

Vent Levers for Adjustable Air Flow

The easiest way to control the flow of air in your heating system is to use a vent lever adjustable air flow system that allows you to actually control where the air goes. These systems are installed directly on your furnace’s air handler. Each vent lever can be attached to a specific thermostat in your house or the vent levers can be opened and closed manually from the basement. When one of the thermostats is turned off, a vent lever will close off air flow to that particular room and stop any heat from being distributed there.

The system itself is not as easy to use as a zone control system but because the technology is simple and it takes only a few seconds to the turn the vent levers, it’s a viable and effective method to control your heating if you cannot afford zone control. If you’re not sure whether this is a good solution for your particular furnace, an HVAC contractor can help.

How to Get Vent Levers Installed in Your Home

If this sounds like a good solution for you, take some time and contact your local HVAC service provider to learn more about what it takes to have vent levers installed. For some systems it is relatively easy to add them to an existing air handler. In older systems or in the case of a boiler, you may need to install more specific types of handlers to control the flow of heating to each room in your home. A professional can give you a better idea of what your home needs and how it can best be setup.
