Even the best surge protector in the world is useless unless it’s properly installed and maintained. If the product uses a light as the failure indicator, make sure it is installed so the light can easily be seen. With units placed behind an entertainment center or curtain, it is hard to know if they are [...]
There are a couple of things that can cause your central A/C not cooling properly
1. Your condenser may be dirty.
2. There may be inadequate air flow around the condenser.
3. There might be a leak, and your unit is out of refrigerant.
[...]
A few simple steps can add up to a load of savings.
Set your thermostat at 78°F or higher. Each degree setting below 78°F will increase your energy consumption by approximately 8%.
Use bath and kitchen fans sparingly when the air conditioner is operating.
Inspect and clean both the indoor and outdoor coils. The indoor coil in [...]
Neglecting necessary maintenance ensures a steady decline in air conditioning performance while energy use steadily increases.
Keeping your system properly maintained will lower energy and repair costs, prevent breakdowns and prolong the life of your equipment. Some maintenance jobs should be left to the professionals, but there is much that you, as a [...]
If you are having comfort or air circulation problems in your home, investigate the ductwork to see if it is contributing to or causing the problem. Begin by locating the ductwork, tracing it from the heating or cooling unit to the rooms it serves. Now that you know where each branch duct leads, you are [...]
Portable fans are usually used for circulating inside air, rather than moving air into-or-out of the home. These are some of the most inexpensive fans to purchase and have very low operating costs, since they generally use less than 200 watts of power. At six cents per kWh, a 200-watt portable fan can run for [...]
Introduction:
Wind energy is one kind of green energies which is never exhaust
ed to use. Wind energy is available free of cost.
A windmill is an engine powered by the energy of wind. It often refers to an engine contained in a large building as in traditional post mills, [...]
NEW YORK: Solar power should become a mainstream energy choice in three or four years as companies raise output of a key ingredient used in solar panels and as China emerges as a producer of them, according to a report by an environmental research group.
“We are now seeing two major trends that will accelerate [...]
Given the static nature of most data centers, cooling infrastructure is often integrated into the physical structure of the building. But what happens when built-in AC is not enough to adequately cool the environment or, worse yet, goes down?
The average server puts off approximately 1,200btu, so IT managers know it is not long before temperatures [...]
Room air conditioners are a sensible cooling solution for apartments or situations where you only want to cool one or two rooms.
In some cases, several small air conditioners may be better than one larger, central unit, because they can be turned “off” individually when not needed. In areas where the cooling season is not too [...]
The Diagram below will give some idea how a central air conditioner for your house works:
A central air conditioner uses the furnace’s blower to draw room air into the unit through return-air ductwork and a filter that removes dust, hair and lint. The room air moves past a chilled indoor coil-the evaporator-to release its heat. [...]
Some parts of the house are never comfortable, no matter what you do. The rest of the house is fine, but one room is always too hot or too cold. Why is that, and what can you do to fix it?
Your problem is probably caused by bad air ducts and/or poor insulation and windows [...]
To stay comfortable, there must be some moisture in the air, however excess moisture can cause problems. Moisture originates both inside and outside the home. The problems it creates can be controlled by minimizing the amount of moisture produced inside the home, minimizing the amount of moisture entering structural cavities like walls or attics, [...]
If you’re building a new house, this can be a real concern. Your architect should be able to design adequate ventilation as part of the plan. But if you have an older house, there are usually enough ways for air to get into your house that tightening up will save you energy but still leave [...]
The best solution to electrical interference is eliminating its source. Here are some easy steps to try:
1. Turn on the appliance that is experiencing interference. Next, flip the circuit breakers in the Home off, one-by-one. When the interference disappears, you have found the circuit that is causing the interference.
2. [...]
The basic notion is that moving air (from ceiling, whole-house, or portable fans) makes you feel cooler, so you can turn up the air conditioner thermostat or turn it off altogether. Whole-house fans are a potential substitute for air conditioning, since they move large amounts of air through the house and require open windows. Savings [...]
While a blower door test is the best way to locate duct leaks, you can often locate supply duct leaks with your hand because supply leaks blow air out. However, return leaks draw air in, so you won’t be able to feel them easily. Duct repair professionals use a smoke pencil to detect return [...]
Conservation represents an investment and operational decision to use less energy in our daily lifestyles. While not advocating “freezing in the dark,” we all need to be mindful of how our behavior and purchase decisions influence our energy use. Our home purchase and utilization are the most significant ways we can each make our mark [...]
Always try to reduce your need and save Energy—— This savings is essential not only for your benefit , but for the benefit of the whole Human Community……For the better and healthy existence of your kids and the generation NEXT.

In hot-humid regions, protecting the home from the hot summer sun and assuring good air movement in and through the site are the most important site design considerations. Therefore, site the home to maximize shade and wind flow. Position the home high to allow for air movement.
Orient the home to face south or southeast. The [...]
Site planning in hot-arid regions has three primary objectives: The first is maximizing shade in the late morning and all afternoon. This is especially important for outdoor living areas. The second is to maximize humidity, and the third is maximizing summer air movement.
To accomplish these, the best orientation is generally 25 degrees south-southeast. Position [...]
Properly sizing an air conditioner is important, especially on whole-house systems. An improperly sized unit can cost you more to operate, and worse, leave you either uncomfortably warm, or cold and clammy depending on whether it is under or over sized. To shop knowledgeably, you should know that air conditioners are rated by [...]
Most people make energy investment decisions based on installed cost and expected savings. Unfortunately, these are not as simple to predict as they might first appear. Cost estimates depend on the quality of materials, quality of the contractor selected, and many design details. Savings for a combination of energy efficiency usually measures less than [...]
NEW DELHI: Commenting on the UN report on climate change, R K Pachauri, chairman of the UN’s Intergovernmental Panel on Climate Change (IPCC), said: “It’s a stunning and razor-sharp report.â€
Pachauri told TOI from Bangkok: “It is a solid scientific document that clearly highlights the urgency with which the issue needs to be addressed by [...]
The most common heat pump efficiency measurement is called the Coefficient of Performance, or COP. COP is the ratio of the heat pump’s BTU heat output to the BTU electrical input, as shown in this equation:
COP = Heat Delivered (BTU/Hour) Divided By Electrical Input(Watt)x3.413 BTU/Watt-Hour
Conventional [...]
How you operate your air conditioner can make a big difference in what it costs to cool your home. Here are some tips that can help keep your operating cost low without sacrificing comfort.
Minimize Use – In mild weather, using natural ventilation or fans at night, and keeping the house tightly closed during hot [...]
Making “energy efficiency” a priority in selecting a new air conditioner will mean lower utility bills for many years to come. For most of the country, compressor-driven air conditioning systems are about the only choice, other than natural cooling or fans. The other option, evaporative coolers, only work well in arid regions like the southwest.
The [...]
Central air conditioners are designed to cool the entire house. Most are known as “split systems,” meaning the air conditioner’s main components are separate from each other.
The cooling coil evaporator is mounted inside the home, usually in the furnace plenum; while the other major components (the compressor and condenser coil and fan) are located [...]
The refrigeration cycle uses a fluid, called a refrigerant, to move heat from one place another. We usually think of the cycle being used to create cooling, but if you have ever felt the back-side of a refrigerator or air conditioner, you know the cycle also produces heat. This is especially true of a heat [...]
Two-thirds of all homes in the United States have air conditioners.Choosing a new high-efficiency can save money and electricity.
Air conditioners use about 5% of all the electricity produced in the United States, at a cost to homeowners of over $11 billion. As a result, roughly 100 million tons of carbon dioxide [...]
