It costs you more money and uses more energy to heat and cool your home than any other system in your home. Typically, 44% to 50% of your utility bills pays for heating and cooling your home.

Regardless of the type of home comfort systems you have in your house, you can save money and increase comfort by properly maintaining and upgrading your equipment.

Keep in mind that an energy efficient air conditioner alone will not have as great an impact on your energy bills as using an approach that involves the entire house. If you combine proper equipment maintenance and upgrades with appropriate insulation, weatherisation and thermostat settings, you can reduce your energy bills by up to 50%.

General Cooling Tips:

* Use house fans. House fans help cool your home by circulating cool air throughout the house. They are most effective when the outside air temperature is cooler than the inside and when operated at night. An attic fan can blow away hot air that accumulates in the attic. This can go a long way to help the efficiency of your air conditioning system.
* Set your thermostat as high as comfortably possible. By maintaining a minimum difference between indoor and outdoor temperatures, you’ll lower your overall cooling bill.
* Don't reduce your thermostat setting to a colder temperature than normal when you turn on your air conditioner. This will not cool your home any faster and could result in excessive cooling and unnecessary expense.
* Set the fan speed on high, except in humid weather. When it's humid, set the fan speed on low.
* Consider ceiling fans to help spread the cooled air more effectively through your home without greatly increasing your power use.
* Keep lamps and TV sets away from your air conditioning thermostat.
* Shade air-conditioning units by planting trees or shrubs, but make sure you do not block the airflow. A unit operating in the shade uses up to 10% less electricity than one operating in the sun.
* Close shades or curtains on east, south, and west-facing windows during the hours when the sun’s intensity is at its peak. Open curtains and windows during early morning and overnight hours when the air outside the home is cooler.
* Turn off the air conditioner if the house (or air-conditioned rooms) will be unoccupied for an extended period. Use a programmable thermostat to turn Air off and on automatically when you know the house will be unoccupied.

Here are a few more steps you can take to substantially improve your home’s energy efficiency.

Take a Holistic Approach to Total Home Energy Conservation
To achieve the maximum in total home comfort and energy savings, we recommend that you step back and look at the big picture of energy consumption in your villa. The fact is, your total home comfort and efficiency is the product of many systems: heating, cooling, lighting & electrical, plumbing and possibly others working together. It is the interplay between these systems, combined with the size, age, physical features and location of your home, and even your lifestyle, that combine to produce the total energy efficiency of your home. Changing or upgrading one system, without considering the other factors will usually result in some improvement, but may not deliver the maximum possible benefit.

If you’re building a new villa, or considering a major remodel or system upgrade, consider an Integrated Systems approach. It may cost a little more now, but will undoubtedly save you a bundle over time. Skilled engineers and technicians will look at the big picture when designing a solution for your home.

Conduct a Home Energy Audit

The place to begin when evaluating your home’s overall energy efficiency and deciding how to reduce consumption and costs is with a Home Energy Audit. This takes into consideration much more than just your heating and cooling systems, and will give you a benchmark from which to make decisions and measure your energy saving progress.

Here are some of the heating & cooling factors your audit should take into consideration:

* Insulation in walls, floors, and attic.
* Vapor Barriers in walls
* Quality of Windows — Single or double pane
* Heat loss around doors and windows
* Quality of insulation in doors
* Integrity of ductwork — Any leaks
* Cleanliness of ductwork
* Use of "passive” solar energy
* Use of curtains and other window coverings to prevent heat loss
* Efficiency of heating and cooling systems — Condition of filters, etc.

Consider Purchasing an Annual Maintenance Agreement

You’ve heard the old adage, "If it ain’t broke, don’t fix it?" Well that doesn’t apply to your air conditioner any more than it does to your automobile. However, when your system is operating properly, it is easy to forget. Regular maintenance will save you the time money and headaches of premature system failures and major repairs. It will ensure that your system is always working at peak efficiency and help you avoid excessive energy costs.


Make sure your Air Conditioner is properly sized

Bigger Is Not Necessarily Better - A bigger room air-conditioning unit won't necessarily make you feel more comfortable during the hot summer months and will most likely perform less efficiently and less effectively than a smaller, properly sized unit. Room units work better if they run for relatively long periods of time as opposed to being constantly switched on and off. The longer running time an air conditioner is allowed to maintain, the easier it is for the unit to hold a more constant room temperature. Running longer also allows air conditioning units to remove more moisture from the air, which reduces humidity and increases the comfort level in the room. Check specifications carefully when choosing the right air conditioner for your space. Central air-conditioning systems also require proper sizing. Professionals, however, should perform the sizing of your central air system. Also, do not use the system's central fan to provide circulation. Instead, use circulating fans in individual rooms. Make sure you set the fan of your central air system to shut off at the same time of your cooling unit (compressor).

Use an Air Conditioner with a high Efficiency Rating
Select a room air conditioner that has an A rating or 10 or higher.

How To Stop Drafts and Save On Energy Bills Imagine leaving a window open all winter long -- the heat loss, cold drafts and wasted energy! If your home has a folding pull-down attic stair, a whole house fan, a fireplace or clothes dryer, that may be just what is occurring in your home every day. Drafts from these often overlooked holes waste energy and cost you big in the form of higher energy bills. Drafts are the largest source of heating and cooling loss in the home. Drafts occur through the small cracks around doors, windows, pipes, etc. Most homeowners are well aware of the benefits that caulk and weatherstripping provide to minimize energy loss and drafts. But what can you do about drafts from the four largest “holes” in your home -- the folding attic stair, the whole house fan, the fireplace and the clothes dryer? Here are some tips and techniques that can easily, quickly and inexpensively seal and insulate these holes. Attic Stairs When attic stairs are installed, a large hole (approximately 10 square feet) is created in your ceiling. The ceiling and insulation that were there have to be removed, leaving only a thin, unsealed, sheet of plywood. Your attic space is ventilated directly to the outdoors. In the winter, the attic space can be very cold, and in the summer it can be very hot. And what is separating your conditioned house from your unconditioned attic? That thin sheet of plywood. Often a gap can be observed around the perimeter of the attic door. Try this yourself: at night, turn on the attic light and shut the attic stairway door -- do you see any light coming through? If you do, heated and air-conditioned air is leaking out of these large gaps in your home 24-hours a day. This is like leaving a window or skylight open all year ‘round. An easy, low-cost solution to this problem is to add an insulated attic stair cover. An attic stair cover seals the stairs, stopping drafts and energy loss. Add the desired amount of insulation over the cover to restore the insulation removed from the ceiling. Whole House Fans and Air Conditioning Vents Much like attic stairs above, when whole house fans are installed, a large hole (up to 16 square feet or larger) is created in your ceiling. The ceiling and insulation that were there have to be removed, leaving only the drafty ceiling shutter between you and the outdoors. An easy, low-cost solution to this problem is to add a whole house fan shutter seal. Made from white textured flexible insulation, the shutter seal is installed over the ceiling shutter, secured with Velcro, and trimmed to fit. The shutter seal can also be used to seal and insulate air conditioning vents, and is easily removed when desired. Fireplaces Over 100 million homes, in North America are constructed with wood or gas burning fireplaces. Unfortunately there are negative side effects that the fireplace brings to a home, especially during the winter heating season. Fireplaces are energy losers. Researchers have studied this to determine the amount of heat loss through a fireplace, and the results are amazing. One research study showed that an open damper on an unused fireplace in a well-insulated house can raise overall heating-energy consumption by 30 percent. A recent study showed that for many consumers, their heating bills may be more than $500 higher per winter due to the drafts and wasted energy caused by fireplaces. Why does a home with a fireplace have higher energy bills? Your chimney is an opening that leads directly outdoors -- just like an open window. Even if the damper is shut, it is not airtight. Glass doors don’t stop the drafts either. The fireplace is like a giant straw sucking your expensive heated or air-conditioned air right out of your house! An easy, low-cost solution to this problem is to add a Fireplace Plug to your fireplace. Available from Battic Door, a company known for their energy conservation products, the Fireplace Plug is an inflatable pillow that seals the fireplace damper, eliminating drafts, odors, and noise. The pillow is removed whenever the fireplace is used, then reinserted after. Clothes Dryer Exhaust Ducts In many homes, the room with the clothes dryer is the coldest room in the house. Your clothes dryer is connected to an exhaust duct that is open to the outdoors. In the winter, cold drafts in through the duct, through your dryer and into your house. Dryer vents use a sheet-metal flapper to try to reduce these drafts. This is very primitive technology that does not provide a positive seal to stop the drafts. Compounding the problem is that over time, lint clogs the flapper valve causing it to stay open. An easy, low-cost solution to this problem is to add a dryer vent seal. This will reduce unwanted drafts, and also keeps out pests, bees and rodents. The vent will remain closed unless the dryer is in use. When the dryer is in use, a floating shuttle rises to allow warm air, lint and moisture to escape.
