Atlanta HVAC Guide: Green Your Home Ideas

Monday, May 7th, 2012

Energy costs and depleted supplies force us to consider alternatives to how we lived 20 and 30 years ago. This transformation of thinking is most prevalent in our homes.  Not only are the habits of our lifestyles under consideration, but the very structure of our homes as well.  From materials to furnishings, houses are being transformed.

Remodel versus New Construction

The amount of open land available for development is less than before, so creativity is being utilized to design more compact developments, concentrating homes into multi-family structures and creating communities with shared spaces.

If you need more square footage for a growing family, staying put by increasing the footprint or adding a second story is viewed as more green than starting fresh on a new plot of ground.  In either case, careful consideration to the materials and systems used can have a significant impact on the environment.

Changing Habits and Habitats

From acoutrements to the house design itself, each decision to change an appliance or upgrade the finishes has greener impacts, no matter the choice of color.  Something so simple as converting light bulbs from incandescent to longer-lasting and more efficient compact florescents (the twisty tube ones) is becoming required in many communities and saves serious dollars in utility costs.

Hot water heaters can be combined with the boiler to share the energy.  More energy efficient glass can bring in more solar heat and light and hold it there longer.  Bamboo flooring only takes five years to grow, but can last 60, allowing our supply of trees to replenish.  Getting an energy efficient air conditioner can lower you energy bills during the summer.

Greening Your Home

Transforming the colors on our walls with odorless zero VOC  paints makes the chore fun to do yourself (instead of smelly and causing a headache), satisfying a need to feel accomplished and useful.  Composting left-over food to nourish our vegetable garden contributes to the effort of awareness far more emphatically than just flushing waste out of mind down the garbage disposal.

A Question from Stone Mountain: What Is a Cast Iron Radiator?

Monday, December 19th, 2011

Cast iron radiators are part of a type of home heating system that has been around for generations. While these types of systems have been largely displaced by newer forced air heating in Stone Mountain, they do still hold some distinct advantages over their more modern counterparts.

Cast iron radiators are heated as either hot water or steam is circulated through them from a furnace or boiler. As the cast iron heats up, it radiates the heat outward into the air and can thoroughly heat your home evenly and efficiently.

In fact, heating systems that use cast iron radiators are quite a bit more efficient at heating homes. They also don’t typically have the types of problems associated with certain types of forced air heating like hot spots, cold spots or generally uneven heat distribution throughout the house.

Cast iron radiator heating systems are also typically cheaper to install than forced air systems because they don’t require ductwork. Instead, a closed system of pipes links the radiators to the boiler, and those are much easier to put in place and generally take up much less space than ductwork does.

While radiators can also be made out of some other metals, nothing holds the heat as well as cast iron radiators do. It is also safer to heat cast iron to higher temperatures, so you don’t have to worry about keeping them on too long or running them in extreme circumstances. They also hold the heat extremely well, so they can continue to heat a room even after the heat has been shut off.

Of course, cast iron radiators are not a solution for keeping your home cool in the winter as some of the newer heat pumps and other central forced air heating and cooling systems are. If you have cast iron radiators in place, you’ll still have to invest in some type of air conditioning system if you want to keep your home cool enough in the summer.

Also, because they do get very hot, cast iron radiators can present a potential burn hazard, particularly to small children.

A Guide from Stone Mountain: How to Maintain High Efficiency Heat Pump Filters

Wednesday, December 7th, 2011

The filter on your heat pump is an integral part of your Stone Mountain home’s comfort system. Without that filter, the device will quickly be subjected to an influx of debris and contaminants that can get into the machinery and the air being filtered into your home. As a result, you need to make sure you properly maintain the filters to reduce stress on your heat pump.

Change Your Filters

High efficiency filters are designed to remove as much of the airborne contaminants in the air as possible. This is fantastic for keeping your indoor air clean. But if you don’t properly maintain the filter, air quality can worsen and your heat pump is put under unnecessary stress. Specifically, the extremely tight knit filter, designed to stop nearly anything from getting through, gets clogged.

Now your heat pump is forced to work much harder to draw the air it needs from outside and heat or cool your home. On top of that, the filter is filled with contaminants that can start to leak back into the air supply, actually making your indoor air quality worse than it would be otherwise. That’s why it is so important to clean your filters on a regular basis (for permanent filters) and replace them if they are one time use.

Recommended Filters

You have options as to which types of filters you use for your heat pump. Filters come in multiple options, from super high MERV rated filters that trap up to 99% of all contaminants as small as 0.3 microns.

Electrostatic filters are especially efficient because they extract contaminants of all types – from dust and mold to smoke and gas fumes. A good filtration system should effectively remove anything from the air without needing replacement too often.

Permanent filters tend to offer the best protection against airborne contaminants and generally need to be cleaned once a month. HEPA filters are often permanent and while each filter is different, these are often extremely effective at minimizing contaminants in the air without putting stress on your heat pump.

Is Your Furnace Making too Much Noise? A Tip from Dunwoody

Wednesday, November 16th, 2011

The old saying that “It is better to be seen than heard” certainly applies to the mechanical equipment in your Dunwoody home. If you hear a squeaky noise or loud clattering you automatically suspect that something is wrong. And if that noise is coming from your furnace, you better pay attention to it. A noise is an obvious sign of a problem – minor or major – and it could result in mechanical failure that could leave your home cold and uncomfortable – and affect your home’s indoor air quality.

Today’s newer variable-speed furnaces keep a constant airflow through the ventilation system utilizing a low speed fan that consumes small amounts of electricity. Constant airflow brings in fresh air and keeps the room air from becoming stale or stagnant. Because of this constant operation, it is important to ensure the furnace is running at peak efficiency, which also means that it is running quietly.

Here are some common noises, possible reasons, and suggested repairs. As always, if you are in doubt about how to repair your furnace, call a local qualified heating contractor and schedule a service call.

  • Squealing noise – could be a worn out or slipping blower belt. Check for proper tension of the belt or replace the belt if it is worn out or cracked.
  • Squealing noise – could be worn out motor shaft bearings. Lubricate the blower motor at the proper points.
  • Rumbling noise – often caused by a poorly adjusted pilot light when the burners are turned off. Adjust the pilot as necessary.
  • Rumbling noise – often caused by dirty gas burners when the burners are switched on. This problem requires service from a qualified heating technician.
  • Buzzing noise – often caused when a blower motor mounting come loose. Tighten the mounting screws or use shims to fill gaps.
  • Hissing noise – indicates a possible air leak. This problem requires service from a qualified heating technician.
  • Ticking noise – possibly a leaky gas valve. This problem requires service from a qualified heating technician.
  • Rattling noise – could be a dirty fan blade. Wipe the fan blade or clean with degreaser.
  • Rattling, grinding, or whining – could be resistance to airflow that causes the motor to work harder. Check the vents in each room for dirt, debris, or obstructions and clear them.
  • Vibrating noise – may not be the furnace but loose or cracked seams in the ventilation system. Check the ductwork seams and hangers to ensure everything is tight. You may need duct tape or bracket hardware.

The best way to keep your furnace and ventilation system from making noises is to practice preventative maintenance. Have your furnace checked annually by a qualified heating contractor – and enjoy the peace and quiet.

When Should You Replace Instead of Repair Your HVAC Equipment in Alpharetta

Monday, October 3rd, 2011

We all dread an expensive repair in Alpharetta, whether it is a car that needs a new transmission, a leaky roof that needs new shingles, or electrical wiring that has been chewed up by a wild animal. Equipment repairs are a necessary evil. We often try and put bandages on things that we know should be replaced but we just can’t afford to replace them.

The same can be said about your home’s heating and cooling system. When your heat goes out or your home just doesn’t seem to be heating or cooling to the setting on your thermostat, your first inclination is to check and see if it is running. Some people will put their hand over a vent to check for hot air while others may check to see if the furnace or air conditioner is running. Maybe there is a blockage in the ventilation system or a blown circuit breaker, two relatively easy fixes.

If the furnace or air conditioner isn’t working after checking the obvious symptoms, your next move is to call for service. Any qualified heating and cooling professional would be able to diagnose your problem and offer suggested repairs. Something relatively minor like a bad circuit board or blown fan motor are not real expensive repairs and are the best option versus replacing the equipment. And you may keep experiencing the same problem and getting the same repair work done – anything to avoid an expensive replacement.

But at some point the vicious cycle will come to an end. Your repair bills will begin to inch their way past the cost of replacing the furnace or air conditioner. You can only bandage a problem so long before it becomes “unfixable.” You may not want to pay an expensive replacement bill but consider the alternatives.

First is the obvious – it costs too much to keep repairing the old HVAC equipment. Secondly, you never know when the furnace or air conditioner may break down and its failure to operate could have dangerous effects on the people in your home, especially if someone is sick. Third, your HVAC system may not be able to keep up with the demand due to lifestyle changes, i.e. an addition put on the house, carpeting removed and wood floors exposed, a new window, door, or skylight added, etc. Your old furnace or air conditioner may not have been designed to keep up with these changes and the repairs are only delaying the inevitable.

Your HVAC System and Ventilation: Some Tips From Braselton

Wednesday, August 31st, 2011

The vent system in your Braselton home is vital to the operation of your HVAC system. Without successful ventilation, your home won’t have the necessary clean air to keep you and your family healthy. So, what does proper ventilation require and how can you ensure your home has it? Here are some quick tips.

Install the Right Parts from the Start

Proper ventilation should result in even air pressure in your home to avoid problems with gas pilot lights. It should also be as energy efficient as possible and provide clean air through proper filtration and cleaning of the air that comes in. The best way to ensure your home has the ventilation needed to stay comfortable and safe for your entire family is to check the total size of the home and then measure the concentrations of certain pollutants like dander, pollen and smoke. A contractor can provide these services for you.

Energy Loss

Another major ventilation issue to keep in mind is energy loss. Ventilation tends to remove heated or cooled air from your home, forcing your furnace or air conditioner to work harder to replace it. As a result, you pay more for energy and it’s never quite comfortable inside.

To avoid this problem, ask about an energy recovery ventilator. These devices are designed to transfer heat from one environment into another. So, in the winter, heated air inside is kept inside and in the summer, cooled air is kept inside. The result is a much lower energy bill without a disruption to your ventilation sources.

Supplements to Ventilation

Proper ventilation should not only provide fresh air, but it should also ensure your home has clean air. The air outside may be fresher, but it can be filled with pollutants like pollen, dander and smoke. These should be removed before they get inside and into the lungs of your loved ones. To do this, you need a full sized air cleaning system that removes particles from the air down to 0.3 microns.

HEPA filters can do this, as will electronic air cleaners which can ionize and remove smoke and gas particles. Make sure you discuss filtration and cleaning with your contractor when they visit your home.

Humidification/Dehumidification

Wednesday, July 27th, 2011

Most people don’t think much about the humidity in their home unless it gets unbearably high in the summer or extremely low in the winter. However, even slightly low or high humidity levels can have a huge impact on your indoor air quality, so even if you feel comfortable most of the time, a humidifier or dehumidifier is something you should look into. Many homes have humidity problems, and even if it’s not something you notice on a regular basis, air that’s too moist or too dry can have a large impact on your family’s health and the overall quality of your indoor air.

The Risks of High and Low Humidity

There are many reasons that proper humidity in your home is so important. For one thing, air that’s too humid promotes the growth of things like mold and dust mites that are significant airborne allergens. Without enough moisture, however, mold and dust mites can’t grow, so if you keep your indoor humidity below 50%, you’ll likely never need to worry about these allergens disrupting your family’s health or causing damage to your furniture.

But, dry air isn’t much better. Once the humidity level gets below 35%, a number of negative things can happen. Dry air enhances the symptoms of asthma, colds and allergies, and it causes damage to the wood fixtures and furnishings in your home. Even if it doesn’t do so much damage, dry air is simply uncomfortable, causing dried out skin, eyes, and hair.

Why Humidity Control Matters

Even if you have a state of the art air quality system installed in your home, humidity is very much something you need to be concerned about. Air that’s too moist or too dry can actually make it more difficult for indoor air cleaners and filters to get those contaminants out. In effect, poor humidity control makes every aspect of your air quality worse.

So if you want to be sure you’re getting the most possible out of your indoor air cleaner, the best thing you can do is put in a good humidification system as well. And when you’ve done that, you may even find that you can turn down the heat and air conditioning as well. Properly humidified air makes home heating and cooling more efficient, saving you both money on your monthly energy bill and wear and tear on your system. No matter how you look at it, proper humidity control is good for you and your home.

Whole House Air Quality System. What Is It? When and Why Do You Need It?

Friday, July 1st, 2011

There are many ways to control the indoor air quality of your home. The easiest way to is to clean your vents and ducts. This reduces the number of pollutants like mold and dust that get into your air each day. In some cases, however, you may need something more powerful and that’s where a whole house air quality system comes in.

What Does Whole House Air Quality Provide?

There are many filters and purifiers on the market that can be operated in a single room such as your living room or the bedroom of your child. However, if you have a more substantial contaminant problem, a whole house system actually attaches to the source of fresh air.

Most whole house systems integrate directly into the ventilation ducts and fans of your house. This ensures the air is purified and cleaned as it enters your home, not after it has circulated for some time. Air cleaners are also integrated into ducts where UV lighting and ionizers can remove bacteria, viruses, smoke and exhaust fumes that come in from outside.

Your furnace and air conditioner will also be filtered above and beyond standard manufacturer filtering, ensuring there are less contaminants traveling through your ducts to start with.

When Do You Need It?

The upgrade to a whole house system isn’t just for those suffering from dust, pollen and pet dander. These can easily be removed with regular cleaning of your ducts and a HEPA filter in each room affected. However, if your home tests high for various gases, exhaust fumes, or molds that are beyond your control, a whole house system is a great way to protect yourself.

In particular, these systems are useful when the contaminants come in from outside. Most indoor contaminants can be removed with careful maintenance of your comfort system, but if your neighbor has a leaky exhaust pipe or if you live near a busy highway, you can’t do much about it other than to filter the air as it comes inside.

Choosing a whole home air quality system starts with knowing what you need to filter. So, proper air testing is highly recommended. After testing, make sure your current systems will integrate well with the new air quality controls. If everything works properly, you’ll be well on your way to fresh, clean air in no time.

Breakdowns – How to Handle an Overloaded AC

Wednesday, June 22nd, 2011

The last thing you need on a hot summer day is for your air conditioner to suddenly cut out. Without the cooling power it provides, your house will get uncomfortable quickly. Fortunately, once you know why this happens, there are several things you can do about it.

Why Air Conditioners Cut Out

The most common reason for air conditioner failure is an overabundance of pressure in the unit. This happens because the coil gets too hot, causing the pressure to rise in the entire device. As the pressure rises past a certain point, an automatic safety shutoff system is engaged. If you can stop the coil from heating up to this point, you can keep your air conditioner running.

How to Keep Them Running

Of course, this is easier said than done. Since your condenser unit with the coil inside is located outside in the heat, it’s only natural for it to get hot during the day – especially an extra hot day when you’re using your air conditioner a lot. You also need to be careful not to put anything over or up against your outdoor condenser unit.

While this may block the sunlight, it will also keep heat in the system and prevent the air conditioner from removing exhaust naturally. So in order to keep your air conditioner as cool as possible, make sure there is nothing up against the vents or impeding air flow in any way. Once you’ve done this, try and find a way to provide shade for you air conditioner without placing objects near the device. Blocking out direct sunlight is the best way to keep your air conditioner cool as long as you can do it without interfering with the system’s natural air flow.

Getting it Back On

If your unit does cut out on you, don’t despair. The best thing to do is to wait about a half hour to give your unit a chance to cool off on its own. Then, spray the coil and other overheated areas with a fine mist of cool water. This should lower the temperature enough that the system can come back on without any further complications.

If the problem persists despite the work you’ve done to keep it cool, you may want to call in a professional to take a look and make sure nothing is broken or worn inside to cause the overloads. Most of the time a little maintenance will take care of the problem, but if not, you’ll want to get repairs done quickly to avoid a full breakdown.

The Energy Star Label

Friday, April 22nd, 2011

The Energy Star program is a joint program of the US environmental protection agency and the US department of Energy. The program’s goal is to help consumers save money and protect the environment through energy-efficient products and practices.

The best-known aspect of the Energy Star program is the Energy Star label, which is awarded to appliances and other items that are significantly more efficient than average. Energy Star efficiency guidelines vary depending on product category, but in general, Energy Star products use 20%-30% less energy than minimum federal standards.

The Energy Star guidelines were designed both with energy efficiency and performance in mind. While low energy use is one of the most important criteria for selecting Energy Star appliances, product performance, features, warranty, safety, and durability are also taken into account. Price is also a factor: if a product costs significantly more than other products in its category, it will only receive the Energy Star label if the up-front cost will be recovered through savings in operating costs within a reasonable amount of time.

The first Energy Star labels were given to computers and monitors in 1992. Now labels can be found on many other products, including:

  • Furnaces
  • Hot water heaters
  • Air conditioners
  • Dishwashers
  • Refrigerators
  • Light bulbs (florescent and LED)
  • TVs

Energy Star products can be found wherever appliances and electronics are sold. Look for the blue and white Energy Star label. You can also look for the yellow EnergyGuide label that is affixed to most heating and cooling systems and household appliances. This label is created by the Department of Energy and shows a product’s annual cost of operation compared to similar models. It will often indicate whether a product is Energy Star.

It’s important to note that while an Energy Star label indicates that a heater, air conditioner, or household appliance is more efficient than the minimum guidelines, it does not always mean that you are getting the most energy efficient option on the market. If you are making a major appliance purchase, use the Energy Star label to be sure every model on your “short list” is energy efficient. Then, look carefully at the EnergyGuide label to compare the efficiency of the models you are considering.

The EPA has also extended the Energy Star label to cover new homes and commercial and industrial buildings. To qualify for the Energy Star rating, a new home must use at least 15% less energy than standard homes (built to the 2004 International Residential Code). Energy Star homes usually include insulation, high-performance windows, energy-efficient heating and cooling systems, appliances, lighting, and water heaters.

The Energy Star standards and label have been recognized in many other countries, including Canada, Australia, Japan, New Zealand, Taiwan and the European Union.
