How to Check if Your HVAC System is the Right Size: A Tip From Watkinsville

Wednesday, October 5th, 2011

Do you ever feel that your Watkinsville home just doesn’t get cool enough during the warm months or warm enough during the cold months? You have tried to adjust your thermostat to the right comfort level but it just never seems right. And on top of that, you notice that your utility bills keep going up and up. Even when you dial up the thermostat in the summer and dial it down in the winter to saving on energy usage, your bills are still about the same.

You could try adding fans and shedding clothes during the warm months or wearing sweaters and crawling under a pile of blankets in the cold months. But do you really enjoy living that way? There must be another solution as to why your heating and cooling (HVAC) system is just not keeping you comfortable – and affordable.

That air conditioning condensing unit sitting in your backyard or the furnace in your basement should be your friends. But in many cases, they are not. That’s because whoever installed those HVAC system components didn’t do their homework on your home. The components were sized incorrectly. If a furnace or air conditioner is sized incorrectly, it usually cannot keep up with the demand for heat or cold and often puts such a burden on the equipment. As a result, regular failures and repair bills are commonplace.

And it may not be the fault of the installing HVAC contractor. Over the years your home may have undergone renovations including additions and new windows, which have increased the square footage or demand for more heating or cooling. Those renovations may not have included upgrades to your home’s HVAC system.

So how do you check for the right size? These checks are done including a load calculation, which adds in the size of your home’s living space, number of door and windows where heat loss or gain could occur, and a check of heat loss or gain through leakage in cracks, roofs, crawlspaces, etc. This will determine what size of furnace or air conditioner is needed to meet the heating or cooling needs of your home and its own individual characteristics.

All of these factors are considered when determining the equipment size. In air conditioning jargon, you will hear about tonnage of cooling capacity. An example may be a 2.5 ton air conditioning unit for a 2,000 square foot home. In furnace jargon, you will learn about Btu ratings, which are British thermal units. Most furnaces are sized in 20-25,000 Btu increments. Each is matched to the cooling or heating needs of your home. Your HVAC contractor will likely recommend using a programmable thermostat, too. That way, you can set the temperature of one or more zones in your home to when each zone is occupied.

Is Your Heat Going Out Your Attic? A Fall Maintenance Tip From Johnscreek

Wednesday, September 21st, 2011

As fall approaches in Johnscreek, it is time to start thinking about your heating system. Whether you have a brand new, state of the art home heating system or an older one that’s still getting the job done, you want to know that you’re able to make use of all the heat you’re paying for. There are many things you can do to try and improve the overall energy efficiency of your house including insulating walls and basements, sealing doors and windows, and purchasing the most energy efficient products on the market. But unless you also do something to stop it, you’ll still lose a lot of heat through your attic, and this is something you should fix before the colder weather starts.

How Your Heating System Works

As you’ve probably heard over and over since you were a kid, heat rises. That means that all of the heat generated by your home heating system is going to try and find its way to the highest point in your home (and beyond, if it can). As that heat moves up, the air in the lower levels of your house will cool and your heating system will switch into gear to provide more heat to maintain a comfortable indoor temperature.

If there isn’t a proper barrier, either between your living space and the floor of your attic or between your attic and the outside, the heat your system produces will keep on travelling right up and through your home. That means your heating system will work constantly to keep the living areas of your home comfortable, while you pay extra for heat that goes directly outside.

While this sounds like a dramatic process, it’s probably not something you would be aware of, particularly if you have a new, energy efficient heating system in place. But whether you think your attic insulation is a problem or not, it’s definitely worth getting it checked.

When you’re no longer losing heat through your attic, your monthly energy bills will immediately go down. Plus, your home heating system won’t have to work so hard to keep the living spaces in your home at a comfortable temperature, and that will help to increase the lifespan of your system, saving you even more money in the long term.

How Animal Dander Affects Indoor Air Quality: Some Pointers From Nicholson

Friday, September 2nd, 2011

One of the single most common indoor air quality pollutants in Nicholson is animal dander. The flakes of dead skin, fur or feathers produced by pets and outdoor creatures can be an allergy nightmare for millions of people. Even those without allergies tend to be less comfortable in spaces that have animal dander issues. Here are some things you should know about animal dander and allergies.

What’s the Issue?

Dead skin from dogs and cats is the biggest problem, with 27% of US homes having cats and 32% having dogs. Cats are a much larger allergen producer however. The number of allergy related complaints among cat owners is twice as high as that of dog owners according to the American Lung Association. Male cats are slightly worse than female cats as well. Don’t forget either that fur is not the primary source of dander. Dead skin, dried saliva and even specs of dried feces can contribute to indoor air quality issues. So, short haired cats or dogs are not any better for your home.

Another thing to consider is that pet dander is suspended in the air much longer than any other allergen because of how light it is. We’re talking about days of suspension, after which it settles into carpets, furniture, clothing and anything else with enough surface area to attract the dander.

Health Problems from Dander

For those allergic to animals, pet dander is an instant irritant. Just walking into a home in which a cat or dog is present can have an instant negative effect – including anything from coughing and wheezing to a runny nose or chest constriction.

Unfortunately, the easiest way to remove pet dander is to remove the pet and for severely allergic people, this is usually the only option. For others, however, there are some things you can do. You can remove the allergens themselves with high powered indoor air cleaning or filtration. You can also set aside areas in the house that the pet is not allowed into and take steps to make sure pet dander doesn’t get into the air supply for that room.

Federal Energy Efficiency Rebates Explained: A Guide From Johnscreek

Friday, August 19th, 2011

Federal Energy Efficiency Rebates Explained

You’ve probably seen the advertisements and heard the sales pitches all over Johnscreek. Upgrade your furnace, air conditioner, water heater, or insulation and receive a federal rebate on your taxes for a percentage of the installation cost. The government is seriously invested in improving the energy efficiency of the country, cutting electric bills and helping people stay comfortable. Here’s a quick look at some of those rebates and how you can tap into them.

Energy Efficiency Credits

There is a standard tax credit of 10% of the cost up to $500 or a specific amount between $50 and $300 for any upgrade made to your existing home for heating, ventilation, air conditioning, insulation, roofs, or water heaters. These upgrades must be made on an existing home in which you currently live – rentals and new construction homes are not eligible.

Green Energy Credits

Even better credits are available if you plan on installing a geothermal heat pump, wind turbine or solar system – either PV panels or solar heating. The tax credit here is 30% of the cost with no upper limit. This applies to any existing or new homes and can be applied to both primary and secondary residences.

Are the Tax Credits Worth It?

The big question is whether these credits are worth the investment in a brand new system? For the most part, it depends on your particular situation. If you have a 30 year old furnace and are planning on an upgrade anyways, why not take advantage of a nice rebate and get a more energy efficient system to go with it? However, if you just replaced your furnace three years ago and it works very well with a high energy efficiency rating, it might not be worth the investment.

Learn More

The Energy Star program run by the EPA contains detailed breakdowns of the 2011 tax credits, including what systems are eligible and how to go about claiming them on next year’s taxes. Learn more by visiting their official page.

What is Ductwork and How Do You Maintain It? A Tip From Atlanta

Wednesday, August 3rd, 2011

Most first time homeowners in Atlanta are aware of the importance of their heating and cooling systems. They keep you comfortable throughout the year, pumping heated and cooled air into every nook and cranny of your home. However, there is another system in your home that actually makes it possible for those other two systems to work. And while they are incredibly simple, your ducts must be carefully maintained year after year to avoid heat and cooling loss.

How Ducting Works

Ducts are installed throughout your home to deliver conditioned air from your air handler. The air is pumped into the ducts and directed by your thermostat system to where it is currently needed. Vents are opened or closed to release that heat or cooling and the house is properly tempered. Ductwork is usually made of sheet metal, though some flexible ducting is made with a combination of plastic, thinner metals and fiberglass.

Ideally, ductwork is crafted in such a way that it is air tight and able to deliver large volumes of air to any room of your home for decades to come. However, whether because of improper installation or extreme conditions, sometimes those ducts can come loose or gaps will form. When this happens, maintenance and repair are needed.

How to Maintain Your Ducts

To maintain ductwork, you must first have it cleaned once a year. Sometimes, this may be necessary more frequently depending on how often you use your home comfort system and how big your home is. Effective duct cleaning will remove any excess debris and dust and kill mold that has started to grow. High humidity can be controlled with a dehumidifier in your air handler and is highly recommended for all ductwork systems.

Additionally, you should have your ducts checked for leaks and gaps periodically. This will reduce the chance that your ductwork starts to leak anything out of the house or between rooms. Such leaks cost you money and put undue stress on your HVAC system. Overall, a good ductwork system is one that you never have to think about. Regular maintenance makes that possible.
