Even more surprising is that the question has some basis in fact, as A/C units may emit up to 1.34 pounds of CO2 per kilowatt hour of usage. Replacing outdated air conditioners can prevent the release of several hundred pounds of harmful carbon dioxide every summer. Besides environmental conservation, you can preserve scarce economic resources. In fact, annual savings from air conditioner upgrades can be as high as $65.
As for whether air conditioning is bad for you, the accurate answer mainly depends upon your definition of “bad.” As already mentioned, AC can hurt the environment, but has minimal adverse impact on your health.
If you currently desire a new air conditioner, heed the helpful hints below to get the best deal for your hard-earned funds.
Your first consideration must be making the right match between maximum capacity and cooled area size. The total volume of space a unit is able to cool is expressed in British Thermal Units (BTUs). Thus, you must start by determining the BTU level required to cool interior living spaces. BTUs are calculated by multiplying square footage by 10.
Then, you should add 4,000 to that total. Calculating AC cooling capacity accurately is vital to energy conservation. A unit with either too much or too little cooling power will quickly eat a huge hole in your pocket by consuming exorbitant amounts of electricity.
The next air conditioning system feature to seek is an Energy Star seal. That official mark of approval is issued by the U.S. Environmental Protection Agency and reserved only for AC models with energy efficiency ratings that exceed minimum federal standards by at least 10%.
Another desirable feature is air dehumidification, especially if you reside in a humid location. Air conditioners with an integrated humidifying function enhance comfort by minimizing ambient moisture. This enables you to operate the unit at lower settings, while enjoying equal comfort and less energy usage.
New air conditioners also let you stay Green and lots of green. Wise AC usage keeps both down utility bills and carbon dioxide emission from electricity consumption. Setting your air conditioning to a lower operating level creates a feeling much like being outside. Of course, this makes actual outdoor forays on hot summer days far more pleasant. Running your air conditioner fan only during the night cuts costs even further.
Many AC models have an air recirculating feature that keeps previously cooled air moving throughout your home. Professional installation is also important to ensure that all gaps are properly sealed to prevent cool air from escaping. Your last but not least task is periodic checks to clean or replace dirty or worn AC filters.
Most units require cleaning at 3-month intervals, but you might have to clean yours monthly if you live in an area where air is very dusty or smoggy. These simple DIY steps can help extend the useful life expectancy and energy efficiency of your air conditioning system considerably.
