Spot cool with a window air conditioner. Central air units are designed to work with your heating vents to supply cool air to every room in your house. Granted, you can turn off the registers to limit or stop the air from entering a room, but the central air unit will still be running at full power. One of the ways to use a window unit, in this instance, is to spot cool a room that is occupied, but they can also save energy, be used for whole house cooling, and even during emergency power outages. Spot Cooling A smaller air conditioner can adequately spot cool a room where people congregate. Since even smaller central air conditioning units draw at least 15 amps or more of power, a window air conditioner that draws less energy, but can cool the room, is an effective alternative. There is no reason to cool off the entire house when only one room is occupied. You can save on energy costs and the wear and tear on your central air unit by using a window air conditioner in this instance. Saving Energy Find the amperage rating of your central air conditioner and install window units that are below that rating.

Cooling off the family room, the kitchen and a bedroom with three window units can save energy and be more cost effective than turning on the central air, provided the total amperage of the window units are rated less than the amperage on the central air unit. cost of car ac unitFor example, window unit for a bedroom that uses 5,000 British thermal units is commonly rated at 5 amps. how much power do window ac units useAn 8,000 BTU unit for both the kitchen and the family room are rated at 7 amps each or 14 amps total. car ac unit portableIf the amperage draw on your central unit is 20 amps or greater, you save energy by using three window units instead. Whole House Strategically place one or two window air conditioners around your home and use fans to circulate the cool air.

The largest home box fans use less than an amp of power, so if one 8,000 BTU window air unit is placed in the kitchen and one is placed in the living room, you are using 14 amps. Add in two or three fans to blow air into bedrooms, and you have a total maximum amperage consumption of 17 amps. Running the fans on low increases their efficiency. This works because air blowing over your skin makes you feel cooler at any temperature. This is the same principle of a wind chill index. Power Outage Power up a window air conditioner with an electrical generator during a warm-weather power outage. Unless you have a whole-house generator, your central air conditioner will not be usable during a power outage. However, smaller 5,000 BTU window units can be powered by home generators that are able to handle the amperage. If there is an emergency power outage during a heat wave, being able to power a smaller room window air conditioner off of a generator may be a lifesaver.

After over six months of research looking for the most effective air purification system, my conclusion is that the Guardian Air REME+ purification system is the best whole house air purification system on the market today.The average human takes 30,000 breaths and takes in more than 3,500 gallons of air each day. But is this air clean? Indoor air is the most polluted air on the planet, and we are spending the majority of our time indoors. Unlike other systems that simply filter air, the Guardian Air REME+ (Reflective Electro Magnetic Energy) air purification system actually purifies indoor air with naturally-occurring oxidizers like ionized hydro-peroxides, Super Oxide Ions and ionized hydroxides. With this system, it’s as if your home or office were situated beside a fresh crystal clear flowing stream in the middle of a dense forest. The Guardian Air is today’s most advanced technology for boosting airborne oxidizers, and these oxidizers are crucial for our health. Airborne oxidizers are naturally-occurring molecules that actively search out and destroy surface and airborne pathogens, and other environmental toxins.

Sadly, these natural outdoor toxin-eliminating compounds are found in much lower concentrations or do not exist at all in indoor spaces. This is a major reason why many people are suffering from allergies, “sick-building or home syndrome,” and other chronic respiratory conditions. Many believe a lack of airborne oxidizers is a cause of chronic disease, respiratory malfunction, sick building syndrome and allergies. According to a 2002 World Health Report, it is estimated that almost 3% of all global disease can be connected to poor indoor air quality. The EPA has suggested that only 10% of upper respiratory colds and flus come from outdoor air pathogens [1]. This means that a whopping 90% of the colds we get come from the indoor air we breathe. Approximately 50% of illnesses are caused or aggravated by polluted indoor air, according to the American College of Allergist. And statistics show that the developed world spends anywhere from 75-90% of their time indoors. Estimates show that over half of all American office complexes use out-of-date and contaminated HVAC systems.

This contamination can lead to a host of conditions including allergies, headache, lung irritation, fatigue, asthma and other infectious diseases. Spending more time outdoors in fresh air is a good first step, but sometimes busy lives and schedules get in the way of that. Because of this, it is crucial to purify the air inside the home. The Guardian Air REME+ system helps purify toxic indoor air. In fact, it was used recently by the Chinese government to help prevent the spread of Avian Flu [2]. Using an electro magnetic energy cell to create ionized hydro-peroxides, the Guardian Air REME+ (Reflective Electro Magnetic Energy) whole house air purification system proactively sends ionized advanced oxidizers throughout your entire house or office to destroy pollutants, particulates, microbes, gases and odors in the air and on surfaces, before they have a chance to reach your family or employees. Because it’s installed directly in your HVAC duct, it will help disperse oxidants that kill pollutants and allergens in the air throughout your entire living space.
