Evaporative Coolers

Friday, May 6th, 2011

If you’re looking for an effective alternative to a traditional air conditioning system for your home, an evaporative cooler is a great option to investigate. This is not new technology by any means, but evaporative coolers are rapidly gaining popularity these days for several reasons. While these aren’t the perfect solution for every home, they’re definitely worth taking a closer look at if you’re interested in cutting your cooling costs.

Here are some of the benefits of evaporative coolers:

• Energy Efficiency – Because they cool air through evaporation, evaporative coolers use much less energy than traditional air conditioners to achieve the same results. This will take a big chunk off your energy bills each month.

• Competitive Pricing – You can buy just about any size evaporative cooler for less than a comparably sized air conditioner. And just like air conditioners, evaporative coolers are available in a wide variety of sizes so you should have no trouble finding one to fit the space you need cooled.

• Easy Installation – Whether you opt for a smaller window unit or a larger centralized one, evaporative coolers are at least as easy to install as air conditioners if not more so. The smaller units are made to fit into windows just like a comparably sized air conditioner, and central evaporative coolers operate through the same air ducts as your central heating system. They’re easy to integrate into your home and often less labor intensive than a central air conditioner to install.

• Complete Air Circulation – With an air conditioner, you need to have your windows and doors sealed up tight to keep the cooled air from escaping. But because evaporative coolers work by cooling outdoor air as they bring it into your home, they require other doors and windows in the house to be open to function efficiently. As the evaporative cooler blows cooled air into the house, it pushes hotter air out, leaving you with a comfortable environment and a constant supply of fresh air.

Of course, evaporative coolers aren’t the right choice for every situation. They work extremely well in areas with hot, dry climates, but they have a harder time cooling your home when the air outside is hot and humid. They also require water to keep their cooling pads moist, and if you live in an area where drought conditions are common, it may be difficult to keep up with their water consumption.

Why Install a Ductless Air Conditioner?

Wednesday, May 4th, 2011

As you explore your options in terms of a new home air conditioning system, you will probably have to decide whether you want a system that uses ducts to get the cooled air around the house or one that is considered ductless. Each type of air conditioning system is appropriate in certain situations, so it is important to understand the benefits of each before you can make a decision.

Duct air conditioning systems are the more traditional type on the market today. They generally consist of an outdoor compressor and condenser unit and an indoor air handler. The outdoor unit passes the cooled air through ducts to the air handler, which then takes over circulating the air through the house and back out to the condenser again.

It makes sense to install this type of air conditioning system if you have a large house or if you have ducts already in place. Duct air conditioners can cool a moderate to large sized house quite effectively and they can also be coupled with zone control systems to give you multiple climate zones within your house.

Ductless air conditioners, as their name suggests, do not rely on a system of air ducts to get cooled air distributed throughout your house. Instead, these types of systems use refrigerant lines to transfer coolant from the outdoor compressor to the indoor, wall mounted units. Each of these indoor units can take care of cooling one or two rooms, but in order to cool an entire house with one of these systems, you will need to install multiple indoor units.

However, these multiple indoor units can all be connected to the same outdoor compressor, and they can also be controlled independently. That gives you much greater control over which parts of your house are cooled and how much energy you are using to cool areas that may or may not be occupied.

Ductless air conditioners are generally more energy efficient than ducted ones, but their real advantage comes from the facts that they can be installed even in places where air ducts do not exist or cannot go. If you do not already have ductwork in your house, installing a duct system will add considerably to the price of installing a ducted air conditioning system. In a case like this, a ductless system is much easier and cheaper to install and certainly makes more sense.

What Will an Energy Audit Do?

Monday, May 2nd, 2011

With costs constantly on the rise, homeowners are looking for new ways to save money on their energy bills, such as conserving electricity, using less heat and exploring alternative energy sources. One great way to see how you and your family can use energy more efficiently is to get a home energy audit.

The goal of an energy audit is determine how energy is being used in the home in order to identify and correct any inefficiency. By finding ways to use energy more efficiently, you can reduce the energy used in your home without sacrificing comfort. Efficient use of energy reduces costs and environmental impact.

How It Works

To conduct an energy audit, a professional will use special instruments to inspect various aspects affecting energy use in your home, including construction, occupancy, appliance use, number of windows and doors, and so on. In this way, you can see how well your home is retaining heat and note any places where inside air may be escaping, making your home cooler or warmer than desired. For example, since a lot of heat can be lost through them, upgrading windows and skylights is an inexpensive way to gain a lot in terms of efficiency. Making sure windows are properly sealed, repairing worn weather stripping, and installing new windows with energy efficient certifications (such as LEED or Energy Star) are simple but effective first steps to making your home more affordable and eco-friendly.

Another aspect of energy audits includes prioritizing energy needs in order of importance, in order to reduce the use of energy on less critical functions. This may include collecting data on the local climate and past energy use. This data can be analyzed in order to identify and predict times when higher usage may be necessary, so that you and your family can prioritize according to your budget. For example, if the results of your energy audit show that July is historically the hottest month of the year and the month when you use the most electricity, you can make up for increased cooling costs by using other electrical appliances less. This way you can stay cool without going outside your utility budget.

Other solutions stemming from your energy audit may include installing insulated curtains, unplugging “vampire devices” like cell phone chargers, and avoiding the use of large appliances during warmer times of the day.

If you are one of the many interested in cutting energy costs, while helping the environment, a home energy audit is the first step.
