How To Lower Your Air Conditioning Costs

Whether you live in the deep south or the northeast, you probably have to blast your air conditioning system all summer long to keep cool in your indoor space. Having a properly running AC is essential to staying cool and comfortable throughout the hottest months of summertime. Even if you have a top of the line, brand new efficient system, you energy costs can still be high. However, there are several simple steps that you can take right now to lower the cost of cooling your house.

In order to keep your energy costs down, efficiency is a key component of the process. The more inefficient your HVAC system is, the more money you are going to spend on your monthly bills. One of best ways to maintain an efficient air conditioning system is to regularly replace the filters. Dirty filters will decrease the airflow necessary to cool your home, causing your system to be far less efficient than necessary. Filters are inexpensive, and they should be checked monthly and changed at least once every few months.

Replacing your thermostats with programmable options is a great way to cut down your energy costs while keeping your home perfectly comfortable. While manual thermostats allow you to control the exact temperature in your space, automatic ones give you total control over your system. You can save by programming the thermostat to turn off the air conditioning when you won’t be home, and you can set it to turn back on an hour before you arrive.

If you have the opportunity to get a new system installed, look into energy efficient air conditioning systems. There are a variety of models on the market systems that are designed to use much less energy than other options. If you are outfitting your home with a new system, or you already have an inefficient system installed in your home, consider using a window unit. If your system seems to cool some rooms efficiently while leaving other parts of your house stuffy and hot, a window air conditioning unit can help to cool single rooms at a time. This way, you can conserve energy by not needlessly cooling rooms you are not occupying.

How To Improve Your Bathrooms Ventilation

Poor bathroom ventilation can make matters of personal care awfully unpleasant. While newer, local building codes have learned to account for this issue, many older homes are equipped with bathrooms that do not offer enough ventilation to make the acts of showering or going about ones daily bathroom-related affairs as comfortable as they ought to be.

If your current bathroom doesnt seem to offer you the right amount of ventilation, you can take certain steps to increase air flow and improve your bathroom environment. Blair Harris is the director of Sales and Marketing at A&R Mechanical Services, a Plumbing, Heating and Air Conditioning company that has been serving Amarillo, Texas since 1992, and she thinks that anyone with poor bathroom ventilation ought to try the following in order to combat the problem:

Using an Exhaust Fan
When it comes to improving bathroom ventilation, the use of a fan is truly key. If your bathroom comes equipped with a built-in exhaust fan, dont wait until after youve emerged from the shower to turn it on. Instead, make a habit of running your bathroom fan while you shower so that it can combat all of that added moisture in the air and help keep the atmosphere as cool as possible. If you dont have an exhaust fan in your bathroom, bring in a local plumbing and HVAC company to see if installing one is an option.

Installing a Bathroom Window
You may add a window on one of your bathrooms exterior walls. Not only can a window improve your bathrooms appearance, it can also help tremendously on the ventilation front. If youre not keen on the idea of having a permanent draft in your bathroom, keep in mind that just because you choose to install a bathroom window doesnt mean that youll always have to leave it wide open. By cracking the window for even a few minutes, you can introduce a stream of fresh air into your bathroom and make it more comfortable in the process.

Cleaning Your Vents
If your bathroom air doesnt seem to be circulating well, clogged or dirty air vents could be to blame. To remedy this, try giving your vents a thorough cleaning. If youre not sure how to tackle the task yourself, hire a local air duct cleaning company to do the job for you. You might be surprised at what a difference a single vent cleaning makes.

Adding More Vents
If running your exhaust fan doesnt seem to be doing the job and your bathroom is not a good candidate for a window, another option for improving ventilation is to hire an HVAC company to install custom ductwork. By adding more vents, you can turn an otherwise stuffy bathroom environment into an airy and pleasant one.

Leaving the Bathroom Door Open
Its natural to want privacy while you shower, but if you live alone or have a bathroom thats only accessible via your bedroom, you can leave the door open a crack to improve ventilation and prevent the buildup of moisture and steam. If your living situation isnt conducive to this solution, make a habit of opening the bathroom door once you get a chance to throw on some clothes after showering. This process will at least allow some of that hot air to dissipate, making your post-shower bathroom atmosphere just a bit less stifling.

Opening that Shower Door
If your shower happens to come equipped with a glass door, opening it once youre done bathing can also improve bathroom ventilation. This will help the steam travel through the air more quickly, and in some cases, it might also help reduce the chances of a mold or mildew buildup.

Your bathroom is one of those places that you just cant avoid, so you should do what it takes to make it as comfortable as possible. If the air flow in your bathroom isnt what youd like it to be, contact an experienced plumbing and HVAC company to learn about your options for improving the situation.

Dealing With Hot Spots In Your Home

When the weather heats up, hot spots in your home are a lot more noticeable. If youre one of the unlucky people trying to sleep in a room where your HVAC system has seemingly chosen to neglect, hot spots can go from uncomfortable to unbearable overnight. What most people dont realize is that this can be fixed either by you, the homeowner, or with a quick ac repair call to your local air conditioning company. You dont have to suffer through sleeping in sauna-like temperatures. There are things that both you and your air conditioning company can do to fix this.

How much are your windows contributing to the heat in your room? Old, inefficient windows let heat right in (or cold air right out). If your windows arent sealed properly or dressed with sun blocking curtains and blinds, youll notice a dramatic temperature difference between your room and rooms that are mindful of their windows.

Are your air ducts properly sized and sealed? Air ducts are responsible for transporting cool, conditioned air to each room in the house. If there is a major tear or leak in your air ducts, one or more rooms may lose their cold air to the attic. A few easy signs that you have an air duct leak are:

Inexplicably high energy bills

Dust on the tops and in the grooves of your doors

Hot (and cold) spots in your home

A cold attic in summer and hot attic in the winter

Little or no insulation around your air ducts

DIY air duct repairs are easily botched. For example, most people dont realize that, despite the name, you should never use duct tape to seal your air ducts. (Use a metal or mastic tape.) If you can easily access your attic, take a peak around. If there are noticeable tears or broken seals, you can try to patch them yourself or leave it to the pros. If youre tackling the project yourself, dont forget to insulate your air ducts well. Good insulation not only blocks thermal transfer, it can stop vapor transfer and even quiet the noise from vibrating ducts.

For a full air duct evaluation and professional repairs, call your local air conditioning company. The technicians there can ensure that your homes air ducts are sized, sealed and insulated correctly. Dont forget to check out the energy rebates offered to those who choose to repair, maintain and replace their inefficient air ducts! When your air ducts are performing properly, youll save money, energy and enjoy living more comfortably.

Gas Furnace Type and Functions

Gas Furnace Functions

The process performed by a regular conventional gas furnace is quite simple in theory. The gas furnace is located in a large box and in order to control the temperature in your home or office the furnace takes in cold air, cleans this cold air by running it through an air filter, heats up the cold air by the use of a gas burner and a steel heat exchanger, then distributes the warm air through the ductwork in your home or office by using a blower. So as you can see the theory behind the heating and cooling cycle performed by a gas furnace is quite simple.

Gas Furnace Process

Once the gas furnace has completed the heating process and the warm air is inside your home, the air will begin to go through a natural cooling process. This cooling process makes it necessary to remove the cool air from you home and replace it warm air. This continual air heating and cooling exchange is performed by using return ducts which suck the cool air back to the gas furnace through return air grills and ductwork so it can run through the heating process again. Located on the return air grills and ductwork there is a device called a humidifier. This helps to control the humidity of the air inside your home so that the heated air is not too dry. This is an important process as the air can become very dry as is continues to go through the heating and cooling process performed by the gas furnace.

Gas Furnace Main Types

A conventional gas furnace is defined as anywhere up to 89% AFUE (annual fuel utilization efficiency) whereas anything above 90% is defined as a high efficiency condensing furnace. These high efficiency condensing furnaces are a little more complex than a conventional furnace. It uses slightly different technology to perform the heating and cooling function. The main differences lie in the method used to extract heat from the combustion process and the method used to exhaust the combustion gases. To put it simply, there is not a greater overall efficiency difference in the combustion process in a high efficiency condensing furnace compared to a conventional gas furnace. The difference in efficiency lies in the heat extraction process after combustion has occurred. Both the conventional gas furnace and the high efficiency condensing furnace use gas burners with electronic ignition systems.

The gas furnace heating system can sound a little complicated at first but its actually quite a simple theory. The engineering and design of a HVAC heating system is much more complicated to understand and implement. However, if you put in the effort to understand how a gas furnace works then performing simple maintenance and troubleshooting can be done yourself without hiring the services of a HVAC contractor.

This article has outlined a simplified version of the heating process performed by a gas furnace, and also what happens to the air once the cooling process begins. There are a number of other articles and videos on this Vancouver heating and cooling HVAC website that may also help further your knowledge on other HVAC aspects in addition to the function and process performed by a gas furnace.

Energy-efficiency Electronics Hardware A bridge Fuel To The Future

Demand for energy continues to be a major topic around the world. Renewable energy sources such as wind, solar or hydro power are increasingly being utilized to provide for that demand. Many States have even recently passed laws raising the minimum renewable usage cap that utility companies must implement into their overall supply. But … we still require escalating amounts of energy for agriculture, industry, and to heat our homes and offices. Emerging as a “bridge fuel” to clean energy and renewable resources, the power electronics industry is poised to span that gap with hardware solutions needed to build intelligent power systems.

The Obama administration plans to spend billions of dollars on power conservation and sustainable energy projects as part of a $787 billion stimulus package which is has focused on energy efficiency. Andrew Fanara, of U.S. Environmental Protection Agency’s Energy Star program has famously said. “Energy efficiency is the bridge fuel we must build on and must invest in” he stresses “Energy efficiency is the cheapest, cleanest, fastest way to act.”

In part, the administration’s strategy is to use improved energy efficiency as a method of buying time to invest in and explore emerging and clean energy options. With initiatives like the smart power grid gaining traction, the power electronics hardware that makes it all work and its new designs aimed at increasing energy efficiency will be at the core of the plan.

Already, there is huge demand for power efficiency by consumers found an industry survey. And, consumers are willingly paying a premium for electronic hardware that delivers energy efficiency. This trend anticipates a growing number of electronic hardware devices will be utilized, which lowers costs and drives improved energy efficiency. Measured in dollars per watt this high volume of hardware deployment forecasts the efficiency for power electronics may drop to as low as 12 cents per watt by 2013.

The focal point of “smart power” systems and a national smart energy grid has clearly been on the hardware side of the equation. To be successful, in the not to distant future, engineers will also make use of the intelligence provided by software so that the hardware components communicate most effectively to accomplish maximum reduction of power consumption. The know-how exists now for this integrated software, but it is still far from widespread.

Power Profiling is a valuable energy-efficiency tool that granularly identifies the power consumed specifically by HVAC, appliances, networks, lighting etc. and communicates this information to users. A user profile is developed by use of proprietary algorithms that calculate information regarding a structure’s overall usage, and several data points such as the time of day and its energy consumption history.

The purpose of power profiling is to enable users to know exactly what activities or systems are consuming the most power, including how much, and how that consumption is affected by actions they take. Most HVAC and appliances are not yet enabled so numerous hardware metering devices are used throughout the structure, at least an adequate number to demonstrate to the user what the largest power users are and how to limit consumption.

Home Area Networks (HAN) are increasingly communicating with utilities in addition to the traditional media centers and computers. Both utilities and consumer electronics companies are offering and assortment of hardware solutions with methods of pre-programming and remotely controlling home systems such as water usage, heating & cooling, and appliances. With the arrival of “smart” appliances and new wireless network protocols designed specifically for energy-efficiency, many of these hardware solutions communicate to users and utilities over one or more wireless systems.

ZWave for media and home automation

ZigBee chosen by utility companies because of it’s secure protocol, and

EnOcean a European self-powered energy harvesting technology that powers devices without the use of batteries.

Hardware using these wireless protocols can all be controlled from a single point building management system, or a homeowner’s computer. Even though these technologies are still on the leading edge, trends indicates they are very near to wide-scale adoption, enabling buildings to connect to smart grid applications that exponentially increase energy-efficiency.

Advances in alternative energy sources have provided greener ways of producing electricity and the burgeoning energy-efficiency industry is providing a plethora of energy saving hardware devices to help users re-tool . We can reduce energy consumption with these advances and make strides toward energy independence. Consider what T. Boone Pickens says “In additional to putting our security in the hands of potentially unfriendly and unstable foreign nations, we spent $475 billion on foreign oil in 2008 alone. That’s money taken out of our economy and sent to foreign nations, and it will continue to drain the life from our economy for as long as we fail to stop the bleeding.

Projected over the next 10 years the cost will be $10 trillion – it will be the greatest transfer of wealth in the history of mankind.”

“By investing in renewable energy and conservation, we can create millions of new jobs. Developing new alternative energies while utilizing natural gas for transportation and energy generation; securing our economy by reducing our dependence on foreign oil, and keeping more money at home to pay for the whole thing.”

Moving forward with renewables is a must, but it is also a documented fact that this increased capacity will not be enough to meet upcoming demands and provide energy independence. The tremendous strides being made in energy efficiency technologies are to help stem the tide, bridging the gap.

Save On Your Hcav System

HVAC, the name Heat Ventilation Air conditioning represents the complete temperature of your house or building system. It needs to be designed well and installed in the right position so that it delivers you better results. It should be of a good quality so that it consumes less energy and provide sufficient indoor air quality while controlling the temperature.

Maintenance of furnace and air conditioning system is important!

Regular maintenance of furnace, heating device and air conditioning system is important so that it delivers better results. If it is maintained well then it proves better in terms of energy efficiency. If not cleaned on a regular basis, if there is leaky ac ducts which is ignored then your electric bills will be higher. Your air conditioning system may consume more power than usual.

Careful selection of the equipment is required so that heating, cooling and ventilation is provided properly. It ensures energy efficiency and provides cooling and heating needs. It also helps control humidity, air quality which includes both indoor and outdoor air quality. Choose the one which has a good SEER (Seasonal Energy Efficiency Ratio). It offers higher efficiency if your AC system SEER is high. Similarly, it also proves its energy efficiency based on the SEER rating.

It makes possible lower cooling costs in order to better the energy efficiency of your HVAC system. You would have saved a great deal through out the year, the savings itself may total up to the price of the purchase of new unit. Dont you want to have a good system installed so that you can save a lot?

It is possible to see significant savings in cooling costs by upgrading to a more efficient air conditioner, For example, an upgrade from a rating of nine (older unit) to 13 (base seer rating now) could translate into almost a third less energy used per season. This can potentially result in hundreds of dollars of savings per year.

Although there are many different types of air handling units, for general IAQ implications in schools, air handling units can be divided into two groups: unit ventilators and individual heat pump units that serve a single room without ducts; and central air handling units that serve several rooms via duct work. Unit ventilators and heat pumps have the advantage of reduced floor space requirements, and they do not recirculate air between rooms. However, it is more difficult to assure proper maintenance of multiple units over time, and they present additional opportunities for moisture problems through the wall penetration and from drain pan and discharge problems. Central air handling units have a number of advantages as compared to unit ventilators and heat pumps serving individual rooms.

Saving Money With Energy Efficiency

A home should be an environment that is comfortable in both the hot, summer months and the frigid, cold temperatures of winter. However, heating and cooling your home so that it is comfortable during these extreme temperature periods can get to be quite expensive. If you aren’t careful, you can rack up a huge energy bill during the winter or summer months without even realizing it. Heating and cooling a home requires so much energy, so sometimes consumers can become devastated at the amount they pay at the end of the month.

However, there are ways to save money on heating and cooling your home. These ways often have a less harmful impact on the environment and a less harmful impact on your pocketbook. While these methods may require an initial investment to make them operational, the money you save over time in heating and cooling your home will be worth the initial investment.

Insulate Your Home

The first and easiest way to make heating and cooling your home more energy efficient is to ensure that air is not escaping from your home or seeping in from the outdoor environment. Poor insulation is often the number one culprit in homes that use energy inefficiently.

You can improve the insulation in your home by installing energy efficient windows that are double paned, or you can have the cracks and gaps sealed around the windows with insulating material. You can also add insulation to your attic and prevent warm air from seeping out through your roof. These small home improvement fixes can help you save a lot of money on your energy bill at the end of each month.

Geothermal Heating and Cooling

Another great way to make your home more energy efficient is to install a geothermal heating and cooling system in your home. Geothermal systems rely on the heat that is generated from the ground in order to make your home more comfortable.

The earth is a wealth of energy, but many consumers don’t know how to tap into the energy that is right below their feet. A geothermal heating and cooling system taps into the heat sources and uses them to power an HVAC system. This type of system is expensive initially, but it can save you thousands of dollars in the course of a lifetime.

Solar Heating and Cooling

Solar power is another great way to save money on your energy bills each month. The energy from the sun is completely free and is abundant almost all year round. If you live in an area of the world that does not have a lot of rainfall, solar heating and cooling systems may be perfect for your area.

A solar heating and cooling system uses huge solar panels to absorb the energy from the sun and convert that energy into a usable energy that can help to power an HVAC system. With the energy from the sun powering the heating and cooling system in your home, you won’t have to shell out so much money each month to an energy company.
