Atlanta Mold Removal Question: How Will I Know If I Need Mold Testing Services

Monday, October 29th, 2012

In large quantities, mold can negatively impact air quality in your home. But how can you tell if you have a mold problem? We’ve put together a short list of common signs that mold could be growing in your home in Atlanta. If you suspect that you have a mold problem, you should call a qualified mold removal specialist immediately.

Visually See Mold

Mold growth is pretty common your bathroom. You normally will see black or gray spots of mold growing on shower curtains, shower doors or around your sink. But in your basement, cellar or attic, mold might be more difficult to spot.

Strange Odor

Mold has a very distinct smell. If you notice a persistent, “earthy” smell in certain rooms and areas of your house there’s a good chance that it’s mold. If you notice that whenever you turn on your heater or your air conditioning that there’s a musty smell, there might be mold in your ducts. The only way to be sure is to have a professional mold detection company come out and go through your house.


Mold reproduces by releases spores into the air. The spores float around in the air until they land on a surface. Once there, they can start to reproduce and releases even more spores. When you inhale spores there can be a number of physical responses. Common symptoms include headache, sneezing, irritated eyes, runny nose and irritation of mucous membranes including your throat, nasal cavities and lungs.

Recent Water Damage

There one thing that mold absolutely has to have in order to grow: moisture. Without moisture, mold can’t exist. If you recently had a flood or a pipe break, there could be moisture still present in your floor or walls that is allowing mold to grow. Mold doesn’t always appear after water damage, but it is something to be aware of. One common culprit for this is your air conditioning unit condensation lines. These lines drain water away from your AC system. If they get clogged the unit will leak water which can allow for mold growth.

If you suspect that you may have mold in your home in Atlanta, you should call Cool Air Mechanical immediately. Mold is not something to be taken lightly. It needs to be removed by a professional and treated as soon as possible.

Atlanta Heating Tip: Why Schedule Fall Duct Cleaning

Monday, October 22nd, 2012

Before putting something into regular use, whether it is your car or Atlanta home’s heating system, it is important to provide the maintenance necessary to ensure proper, dependable function. That’s why Cool Air Mechanical suggests scheduling professional duct cleaning this fall before the heating season really gets underway.

When a system is in use for a while, such as your ductwork system, dirt, debris and other pollutants have a chance to accumulate within the system. All of the dirt, dust and biological pollutants that may have built up over time and can be pushed into your living space by the air circulating through your ducts.

Other than indoor air quality,  there are other reasons you should consider scheduling professional duct cleaning service and general heating maintenance this fall. To begin with, this is the only way to ensure that all components of your heating system, ductwork included, are ready to perform the way you expect them to. Don’t expect your heater to just jump back into the swing of things right where it left off. Increased efficiency from your furnace and ductwork is an important factor in reducing energy use and utility costs.

Duct cleaning is also a great opportunity to have the efficiency of your ductwork tested. Forced air heating systems are a very popular home heating option, but the ductwork that they use to disperse heated air is subject to energy loss. Poor design, improper installation or insulation, badly connected joints and air leaks can all affect the efficiency of your system. Duct cleaning itself can help improve efficiency by improving airflow. By testing your ducts for efficient performance at the same time you can go into the heating season knowing that your system is prepared.

Atlanta Heating Guide: Tips for Starting Your Heating System for the First Time

Monday, October 15th, 2012

Each year we switch from needing our air conditioning system to using our heating system. No matter what heating system you have, whether it’s a furnace or a heat pump, you should take a couple minutes to inspect the unit. We’ve put together a quick list for you to look over before you start using your heating system. Having your heating system inspected and maintained by a professional Atlanta heating company can potentially extend the life of your unit and also keep it operating at peak efficiency.

Check Your Smoke and CO Detectors

Before you do anything with your heating system, you should check your smoke, fire and carbon monoxide detectors. These safety systems protect you from serious injury and property damage. Check the batteries in each of your detectors and test the unit using their built in testing system.

Mechanical Inspection

After checking your detectors, you’ll want to look over the side panels of the heating system to check for rust or damage. Make sure the doors are still properly sealed. Look on the ground for signs of leaking water. Inspect the evaporator coil’s connection to the furnace to make sure that it is not corroded. While these are things your technician will also check during your maintenance visit, you can fill them in with any potential problems you have noticed.

Air Fitlers

Check the air filters in your heating system to make sure that they are not clogged. If it has been more than thirty days since you last changed the filters, go ahead and switch them out for a new one. Also check the ductwork going from your heating system to the inside of your house for blockage or cracks.

Start the Furnace

Finally, the last thing to do is start the furnace up to make sure that it turns on successfully. This should be done before you need to actually use the furnace so that you can have your system repaired if you need to. Turn your heater on and set the thermostat to a temperature that is higher than home’s current temperature. If the system doesn’t start within 3 to 5 minutes then call your local Atlanta heating company for service.

If you’re interested in having the heating system in your Atlanta home professionally inspected, maintained or repaired then call the heating experts at Cool Air Mechanical today!

Atlanta Heating Question: How Do I Switch My Heat Pump to Heating Mode?

Monday, October 8th, 2012

Heat pumps are becoming more popular with homes and businesses located in Atlanta. Heat pumps do the job of an air conditioning system and a heating system. But they are unique from traditional heating systems in that they simply move heat from one area to another as opposed to heating the air by burning a fuel like gas or oil.

The Heat Pump Thermostat

Most heat pump systems are controlled by the home owner using a simple thermostat located inside the home. There is traditionally a setting for either “Heat” or “Cool”. These thermostats are very similar to their traditional air conditioning or heating cousins. They can be programmed to maintain a desirable indoor temperature as well. The only difference is that unlike a traditional thermostat which controls two separate systems, the heat pump thermostat only controls one system.

How a Heat Pump Works

When the homeowner flips the cooling switch, the heat pump will begin extracting heat from the indoor air and expelling it outside. Conversely, when it is cold in the house and the home owners wants heating, the heat pump will take heat from outside (as long as it is above 30 degrees Fahrenheit) and move it inside.  The heat pump absorbs the heat by using a fan or evaporator to move air across a series of tubes containing a highly heat absorbent refrigerant. A condenser located outside the home is responsible for moving the liquid through the tubes, into the house and back outside.

If you’re interested in finding out if it might be a good option for your Atlanta home, then call the heating and air conditioning experts at Cool Air Mechanical today.

Atlanta Heating Question: What Is a Gas-Fired Infrared Heater?

Monday, October 1st, 2012

Put simply, a gas-fired infrared heater is a device that heats people and objects directly (as opposed to heating the air) and is powered by a gas-combustion burner. These types of heaters come in many shapes and sizes, and they can be very useful in a variety of situations. To find out which type of gas-fired infrared heater is right for your Atlanta home, you will have to compare the relative power, orientation and other features of the various available products.

Why Choose Infrared Heating?

While conventional forced-air heating systems work well in residential and office settings, they are extremely inefficient when applied to larger open spaces like those found in warehouses, garages and airplane hangars. In these types of situations, infrared heating is much more appropriate because the energy of the infrared rays the heaters emit is only converted into heat once they strike an object.

For example, an infrared heater mounted on the ceiling of a warehouse is not intended to heat the products stored on the top shelves – it’s meant to make the workers in the warehouse comfortable. It is very effective at this because even though it is located up high, its energy only turns to heat when it strikes the floor, allowing for the re-radiation of that heat at exactly the right level to keep people warm without losing heat to the vast open space above.

A forced-air system installed in a similar setting, even when the vents are right at floor level, will simply be pumping hot air up towards the ceiling (or out an open bay) leaving workers on the ground cold and uncomfortable. Of course, this technology isn’t just useful in a large commercial setting. It can also be applied on a much smaller scale in your own garage, allowing you to work comfortably with the garage door open even in the middle of winter.
