Indoor air quality is one concern that building managers and building inhabitants have when they decide to investigate their HVAC system. Through normal occupation in a building, we generate a great deal of contaminants and air pollutants, such as dander, dust, and chemicals. These contaminants are pulled into the HVAC system and re-circulated 5 to 7 times per day, on average. Over time, this re-circulation causes a build-up of contaminants in the ductwork.
While a contaminated HVAC system doesn't necessarily mean unhealthy air, the situation may be contributing to larger health issues or harboring contaminants that could cause serious problems for people with respiratory health conditions, autoimmune disorders or some environmental allergies.
Wet portions of mechanical air systems are notorious breeding grounds for biological contaminants. An annual inspection of a building’s mechanical air system will reveal the severity of contaminant levels within the system and the extent of cleaning necessary. Having a mechanical air system reconditioned will remove allergens like dust, dander, insect remains, microbial growth and bacteria from the system and will, in turn, provide for a healthier environment to live or work in.
Optimize Energy Efficiency
A typical duct system will lose 25 to 40 percent of the heating or cooling energy put out by the mechanical air system. The microbial control cleaning process extends the useful life of HVAC systems while increasing overall energy efficiency by keeping fins, blowers and coils clean and running at peak operational performance.
Increase System Longevity,The mechanical air system may well be the most expensive mechanical system in your building, and replacing it can cost thousands to tens of thousands of dollars and tremendous aggravation. Microbial control cleaning process prevents corrosion often caused by sulfuric acid secreted by common bacteria. This process also prevents rust and corrosion, which can degrade the mechanical air system.
The short answer is anything that your mechanical air system pushes through. This includes, but is not limited to the ducts, air handlers, PIU’s, VAV’s, evaporator coils, and air dampers. In addition, we expertly clean and guarantee your satisfaction. Not only can we do it, but we do clean it the right way.Call Reliable Heating & Air today at 770-594-9969.
There are many different efficiency levels and cooling capacities or “tonnage” of air conditioners available today, but all the different units can be divided into three distinct major types or categories; single stage, two stage and variable speed speed units.The efficiency or SEER rating of an air conditioner refers to how much electricity that particular unit will consume to keep you cool in a season. SEER is an abbreviation for “seasonal energy efficiency ratio” and it tells you how much electricity an air conditioner will consume over a typical season. The higher the SEER the less electricity a unit consumes in a season.
Starting in 2007, the minimum SEER rating became 13. Before this, the efficiency levels went all the way down to 6 SEER or less. The actual savings every SEER number affords you varies, but on the average it is between 5 and 10 percent savings per larger number SEER selected.
The ton of an air conditioner is a rating of the unit's ability to remove heat from your home or business. A ton of cooling is 12,000 BTU’s and residential air conditioners are made in sizes of 1.5 ton to 5 ton in half ton increments. A BTU is a measure of heat which stands for British Thermal Unit and one BTU is equal to the amount of heat one wooden match puts out.
In other words, a 1.5 ton air conditioner will remove the amount of heat the 18,000 matches would emit if they were all burning at the same time. The reason it is called a ton is that is the amount of heat (12,000 BTU) it would take to melt one block of ice weighing a ton in one hour. The job of an air conditioning contractor is determining the correct size or tonnage of a unit for you, and in this case it is not a matter of the more the better.
An oversize air conditioner will not remove the proper amount of moisture from the air to give you the comfort you deserve. An undersized air conditioner will run constantly even at moderate temperature and will not adequately condition the space. There are some air conditioners you can slightly oversize and still get very good dehumidification and those are two speed and variable speed units. A variable speed furnace will also help in having a system that not only keeps you cool, but dry also.
Air ConditionersSingle Speed Air Conditioners,Single speed air conditioners produce the same amount of heat removal all the time regardless of how hot and muggy it is outside. They have to be large enough to cool you on the hotter days of the year and because of that, they are larger than needed on the moderate days. A good contractor selects a unit in the middle, as it is a bad idea to pick a unit sized that will handle a peak day when the bulk of the time we do not see peak temperatures.
This means that on a 100 degree day the unit will run constantly, but that is far better that picking a large enough unit to handle the few days it goes over a 100. Single speed units come in three different SEER ratings; 13, 14 and 15 seer. All these units can use any type of indoor furnace or air handler and they are 35 to 50 percent more efficient than most 15 to 20 year old units you might have in your home or business.
Two speed air conditioners have two distinct output capacities to better condition your home. These units have the ability to change the amount of cooling capacity they produce depending on how hot it is. Because they can slow down and run longer, they do a better job of removing moisture and providing enhanced comfort.A two speed air conditioner can run in low or high speed depending on the temperature outside that day. These units are very efficient and provide a high level of comfort and dehumidifcation.
Variable Speed Air Conditioners,Variable Speed units are the very best air conditioners available and provide extreme comfort and moisture removal unlike any other system available. Instead of turning off and on all day causing temperature swings along with hot and cold spots, a variable speed unit has 700 different outputs to accurately and efficiently provide temperatures to 1/10 of a degree of what is desired.
The Trane True Comfort variable speed units are also the quietest on the market and can barely be heard running. Coupled with a Trane variable speed indoor unit these systems can heat and cool a home for up to 60% less than an older unit and will take out 10% to 15% more moisture in the summer due to their extended run times at very low speed.
