What Does the EPA Do for Indoor Air Quality? A Question from Bevil Oaks

Friday, October 28th, 2011

There are a number of agencies in the United States dedicated to protecting the health and wellbeing of citizens. What does that mean for you in Bevil Oaks? It means many of the rules and regulations related to indoor air quality are directly overseen by the EPA and the US government. For a better idea of how this impacts your currently lifestyle, here’s a quick look at what the EPA does.

Formation

The Environmental Protection Agency was formed in 1970 by Richard Nixon and the US Congress to oversee the regulation and oversight of air, water, land and hazardous waste. In short, the EPA works to keep our environment clean and safe.

The EPA and Homeowners

While much of what the EPA does relates to corporate pollution, regulations for manufacturing and consumer products, and development of safe methods of production for things like oil, food and water, the EPA has a big hand in ensuring your home stays safe.

Specifically, the EPA started and oversees the Energy Star program to help consumers purchase appliances and HVAC systems that use the least possible energy. Additionally, the EPA oversees the measurements and minimum requirements for home insulation and ventilation. This has as direct impact on indoor air quality.

Current EPA regulations are based on the ASHRAE Standards for low rise buildings and has been revised in the last two decades to ensure proper ventilation and insulation to reduce energy waste and maintain clean, fresh air.

The clean air act has a big impact on how homes are ventilated and maintained and the EPA does a lot of public service work to educate the public on ways to stay safe, including a recent campaign to get your home tested for radon – a potentially life threatening gas that can exist in any home, regardless of age.

Getting to Know the EPA

If you have an indoor air quality or suspect there may be issues in your home, one of the best resources on the Internet is the EPA’s indoor air quality website. It contains laws and regulations that impact your home (if you plan on remodeling or adding on to your home) and dozens of resources for testing and understanding the levels of pollutants in your home.

Simple Filter Tips From Liberty on How to Keep Your Ducts Clean

Monday, September 19th, 2011

If there’s one thing you can count on with a home comfort system in Liberty, it’s that there will be higher energy bills in the summer and an increase in dust and debris in your ductwork. But, luckily the latter can be fixed with a few simple filtration upgrades in your home.

The Nature of a Forced Air System

When you flip the switch on your thermostat and your air conditioner or furnace turns on, it starts drawing air from inside your house, conditioning it to the right temperature, and then circulating it back into your rooms through an air handler and ductwork. Of course, a good system should have proper ventilation to circulate new air into the house, but let’s face it – no matter how much ventilation you have in your home, there will always be dust and debris from things like pets, plants and other common household items.

So, when the air gets circulated back through the ducts, all sorts of debris and sediment build up. That’s not to mention the possible presence of actual contaminants like bacteria or mold. Luckily, because of how your forced air system is built, these are not tough problems to deal with.

Installing the Right Filters

Filtration is incredibly important for adding the right level of protection to your home’s ductwork. Usually placed directly within your air handlers, whole house air filters are designed to capture particles as small as 0.3 microns (if you purchase a high quality HEPA filter). That pretty much covers all dust, sediment, pollen, dander and other common allergens.

There are a number of other upgrades you can make to capture just about everything you house spits into those ducts – from bacteria and viruses to smoke and other air pollutants, but at the very least a good filter system will save your lungs, cut back on duct cleaning costs and make it much easier to maintain your home’s air quality throughout the year.

To learn more about HEPA filters and the specific ratings offered in various products, here is a link to the EPA’s guide to home air cleaners. It has a handy breakdown of different types of filtration and what each filter grade can capture.

Will My Air Conditioning Work Better with Dehumidification? A Question From Vidor

Friday, September 16th, 2011

There are a number of common misconceptions about humidity and air conditioning and how one affects the other in your Vidor home. In truth, humidity is a major part of the discomfort we feel when the mercury rises. It can be 78 degrees outside but feel miserable simply because the humidity is high. So, many people wonder whether a dehumidifier is a good solution to moderate heat and how it will work in tandem with an air conditioner.

Humidity and Your Air Conditioner

First, remember that air conditioning naturally lowers humidity because it cycles air through its condenser and evaporator coil. Conditioned air is naturally lower in humidity, regardless of what’s going on outside. So, if it is hot outside and humid, an air conditioner alone is very effective. On the other hand, a dehumidifier is useful is when the temperature isn’t that high but the humidity is.

Dehumidification not only lowers the relative humidity in your home, it reduces the need for cooling because you will feel more comfortable. Not only that, but a dehumidifier costs significantly less to run. So, when the temperature outside isn’t that high, there is no need to use thousands of watts per day of electricity just to stay comfortable.

This also reduces the overall wear on your air conditioner. Since it doesn’t need to run 24 hours a day to reduce humidity, wear and tear on the device is reduced and you save a tremendous amount of money on repairs and eventual replacement costs.

When to Use a Dehumidifier Alone

Generally, the Department of Energy recommends setting your air conditioner to 78 degrees and using a combination of a dehumidifier and fans to stay cool while it is off. If the temperature rises above that level, the air conditioner will turn on and supplement your dehumidifier. Consider too that a dehumidifier will reduce the burden placed on your air conditioner to pull humidity from the air. Humid air takes more energy to cool than dry air. Despite the fact that dehumidifiers will often raise the air temperature by 1-2 degrees, they save energy and make you more comfortable.

So, if you’re looking for a way to reduce your energy bill and enhance the longevity of your air conditioner, look no further than a quality dehumidifier.

Why Are Cleans Filters So Important to AC Efficiency? A Question From Silsbee

Wednesday, September 14th, 2011

Air conditioners cost a lot of money to operate in Silsbee – especially when they don’t work at 100% efficiency. So, it is important to perform the various regular maintenance tasks that ensure the system uses as little electricity as possible. The first thing on your list (and the easiest) is cleaning those filters.

Keeping Filters Clean

The Department of Energy’s Energy Savers website states that you can reduce your air conditioner’s energy consumption by as much as 15% simply by keeping the air filters clean. Why do they matter so much? Consider the nature of a filter.

The filter on your AC unit is designed to capture any dust, debris and sediment in the air supply. If that dust and sediment was allowed in, not only would it gum up the mechanical workings of the device, it would get into your ductwork and reduce the air quality of your home. So, filters are used to capture such things. However, when a filter gets clogged, the system must work harder to draw the air in. As it works harder, the motor turns faster and more electricity is used.

It takes very little to clog the filter of an AC unit, especially if it is running 24 hours a day for two or three months out of the year. So, it’s best to check your filters once every 30 days regardless of what type of filter you are using.

Which Filters to Check

The main filter on your AC unit should be checked along with any air handler filters and any air cleaner filters you have installed in your system. Another thing to consider is the condition of your home and the area around your outdoor condenser. If you have pets, lots of plants or your condenser is located in a dusty area, you may need to check and change those filters even more often.

Most filters are located along the return length of the ductwork – sometimes in ceiling ducts and walls, though they may also be located in your furnace’s air handler or inside the air conditioning unit. If you have window units or mini splits, the filters are frequently in the unit.

Clean air filters are important for your health, your wallet and the longevity of your AC system. Stay on top of them and you will save money in more ways than you might expect.
