Many people are concerned about mold in their air conditioning system. They notice little pieces of black specs coming out of their supply grills. This is especially true when changing over from heating season to cooling. The particles on the cooling coil dehydrate from the heat and re-hydrate when the air conditioner is turned on. All air conditioning system develop some amounts of mold. This is due to the ideal environment of the cooling coil to grow mold. It is dark, cool, wet and there is a food source. Leave one of the components out and you can minimize mold in your system. Removing condensate properly is one way to minimize the wet component. This means the drain pan empties quickly and water does not stand in the coil. Place chlorine pan tabs in the pan helps to remove the mold. Have your cooling coil cleaned by a professional a/c company annually. This will help eliminate

When we think of paying our electric bill, we think of the cost to run our air conditioner. Staying cool in your home is by far the major cost of your electric bill. There are several aspects of staying cool besides running your air conditioner. If you can keep your cool air in your house and keep the warm air outside, you can lower your electric cost. There are many ways to accomplish this with one being blown insulation in the attic. Many homes do not have the proper thickness of insulation for their area. The thicker the insulation layer, the higher the resistence (R value) to heat gain. People living in the south should have an R-30 or the equivilent of 12.2″ of attic insulation. Most companies charge $1.20 per square foot of attic space to blow a fiberglass insulation product to a R-30. On a 1200 square foot home, this would be $1,440.00. Yes, it will take several years to recover your cost but the benefits are worth it. Your a/c will not have to work as hard, last longer and your energy bill will be lower. Best of all, you will be more comfortable in your home.
As much as half of the energy used in your home goes to heating and cooling. So making smart decisions about your home’s heating, ventilating, and air conditioning (HVAC) system can have a big effect on your utility bills – and your comfort.
Change your air filter regularly
Check your filter every month, especially during heavy use months (winter and summer). If the filter looks dirty after a month, change it.
- At a minimum, change the filter every 3 months. A dirty filter will slow down air flow and make the system work harder to keep you warm or cool – wasting energy.
- A clean filter will also prevent dust and dirt from building up in the system – leading to expensive maintenance and/or early system failure.
Tune up your HVAC equipment yearly
Just as a tune-up for your car can improve your gas mileage, a yearly tune-up of your heating and cooling system can improve efficiency and comfort.
Install a programmable thermostat
A programmable thermostat is ideal for people who are away from home during set periods of time throughout the week. Through proper use of pre-programmed settings, a programmable thermostat can save you about $180 every year in energy costs.
Seal your heating and cooling ducts
Ducts that move air to-and-from a forced air furnace, central air conditioner, or heat pump are often big energy wasters. Sealing and insulating ducts can improve the efficiency of your heating and cooling system by as much as 20 percent – and sometimes much more.
Focus first on sealing ducts that run through the attic, crawlspace, unheated basement, or garage. Use duct sealant (mastic) or metal-backed (foil) tape to seal the seams and connections of ducts. After sealing the ducts in those spaces, wrap them in insulation to keep them from getting hot in the summer or cold in the winter. Next, look to seal any other ducts that you can access in the heated or cooled part of the house.
When you have a big air conditioning problem – like an air conditioner that quits during the hottest day of summer – it goes without saying that you’ll call for service. Smaller air conditioning problems are easier to ignore, but this is the last thing you should do. By calling for service as soon as you notice the symptoms of an ailing cooling system, you can prevent the expense and inconvenience of a big repair job. You’ll also avoid the higher utility bills that typically accompany a poorly functioning air conditioning system. You should have your air conditioner checked when you notice any of the following symptoms:
- Decreased air flow from the registers;
- Strange noises coming from the air conditioner;
- Moldy odors coming from the ductwork when the air conditioner is running;
- The air conditioner cycles on and off more frequently than it used to;
- The breaker for the air conditioner in the electrical panel keeps tripping (or the fuse keeps blowing);
- Ice appears on your air conditioner or piping, either inside or outside the house;
- Your outdoor fan in the air conditioner won’t come on.
If you notice any of the above symptoms, call us today to have your air conditioning checked and serviced to avoid larger problems down the road.
