Since most Americans spend 90% of their time indoors, breathing clean air can have an important impact on their health. Our exposure to toxic materials indoors is 5-10 times greater than is outdoors. While outdoor air has a dilution effect on pollutants, indoor air tends to trap and intensify pollutants.

Air ducts naturally accumulate sizable deposits of dust and other contaminants over a period of years and in some cases months. This debris can reduce the efficiency of your heating and air conditioning system and even cause physical discomfort and illness by degrading the quality of air you breathe indoors.

Dust and other contaminates are actually pulled into the mechanical conveyance system through the return side of the system and from exterior sources. These contaminates build up inside the return ductwork. Many homes have inefficient filters, which trap less than 10 percent of the particulate that is drawn in the system. The average six-room house collects 40 pounds of dust each year!

Your Overall Well Being – Duct cleaning improves the health of your home living environment. It is estimated that ½ of all upper respiratory illnesses are caused by poor indoor air quality. According to the Department of Consumer Affairs, children are more likely than adults to be affected by poor indoor air – they breathe faster, inhale more air per unit of body weight, and are closer to the ground where concentrations are higher.

Your Home – Duct cleaning removes a substantial amount of dust and debris from the home, in some cases as much as ten pounds may be removed. These airborne pollutants contribute to dust in the air, on your furniture, and in your carpet.Your Finances – Dust and debris that is drawn into your system will soon overcome a standard household filter and begin to accumulate in the mechanical systems and duct work. Once this occurs the system is less efficient and must run longer to do the same job as when it is clean. The cumulative savings here will pay for the cleaning over a few years. Some 50% of illnesses are either caused or aggravated by polluted indoor air!

Air VentWhat type of procedure does Mr. Cool Mr. Heat use to clean my system.We employ and train highly competent individuals to best serve the needs of our customer. Upon arriving at your home our lead technician will walk through and count the registers in your home while explaining the process to be used in cleaning your system. Source removal duct cleaning is considered the best method for relieving indoor air quality problems and is the only method endorsed by the National Air Duct Cleaners Association (NADCA).

Mr. Cool & Mr. Heat has utilized source removal technology for duct cleaning. We use high velocity compressed air along with a high volume vacuum system (9000 cfm) to dislodge contaminates and pull them from your home. We use specially designed air whips, air sweeps and rotary brushes designed to ensure proper removal of contaminates. All grills, registers, diffusers and plenums are cleaned and sanitized. After the cleaning an EPA approved sanitizer is fogged through the system. This sanitizer will kill mold, bacteria and fungus.

To help ensure a clean, healthy environment, we recommend that air ducts be cleaned every 5 to 7 years. Give us a call at 404-288-6010 if we can schedule your cleaning or answer any questions for you.Dirty blower wheels reduce air flow, causing longer operating time and increased energy cost. This problem can lead to lost comfort and compressor failure. Avoid wasting your energy dollars by verifying that your maintenance includes a thorough check and cleaning of your blower system.

Check the Refrigerant Charge.The refrigerant charge is checked by measuring temperature differential and determining electrical demand on the compressor or by reading the pressure gauges. A low or high refrigerant charge can easily go unnoticed and increase operating costs. An improper charge can also cause compressor shut-down. Periodic checks on refrigerant levels can lower your energy bills and prevent future repairs.

Clean Condenser Coils.Dirty condenser coils will raise refrigerant pressure higher than needed, increasing your electric bill. Cleaning the coils will keep your equipment at maximum efficiency while at the same time, saving you money.Inspect and Clean Out Condensate Drain.Clogged drains will increase the humidity level in extensive water damage. Proper maintenance of the condensate drain will prevent unwanted repair calls.

Another approach to lowering the concentrations of indoor air pollutants in your home is to increase the amount of outdoor air coming indoors. Most home heating and cooling systems, including forced air heating systems, do not mechanically bring fresh air into the house. Opening windows and doors, operating window or attic fans, when the weather permits, or running a window air conditioner with the vent control open increases the outdoor ventilation rate. Local bathroom or kitchen fans that exhaust outdoors remove contaminants directly from the room where the fan is located and also increase the outdoor air ventilation rate.

It is particularly important to take as many of these steps as possible while you are involved in short-term activities that can generate high levels of pollutants – for example, painting, paint stripping, heating with kerosene heaters, cooking, or engaging in maintenance and hobby activities such as welding, soldering, or sanding. You might also choose to do some of these activities outdoors, if you can and if weather permits.

Advanced designs of new homes are starting to feature mechanical systems that bring outdoor air into the home. Some of these designs include energy-efficient heat recovery ventilators (also known as air-to-air heat exchangers).

There are many types and sizes of air cleaners on the market, ranging from relatively inexpensive table-top models to sophisticated and expensive whole-house systems. Some air cleaners are highly effective at particle removal, while others, including most table-top models, are much less so. Air cleaners are generally not designed to remove gaseous pollutants.

The effectiveness of an air cleaner depends on how well it collects pollutants from indoor air (expressed as a percentage efficiency rate) and how much air it draws through the cleaning or filtering element (expressed in cubic feet per minute). A very efficient collector with a low air-circulation rate will not be effective, nor will a cleaner with a high air-circulation rate but a less efficient collector. The long-term performance of any air cleaner depends on maintaining it according to the manufacturer’s directions.

Another important factor in determining the effectiveness of an air cleaner is the strength of the pollutant source. Table-top air cleaners, in particular, may not remove satisfactory amounts of pollutants from strong nearby sources. People with a sensitivity to particular sources may find that air cleaners are helpful only in conjunction with concerted efforts to remove the source.

Over the past few years, there has been some publicity suggesting that houseplants have been shown to reduce levels of some chemicals in laboratory experiments. There is currently no evidence, however, that a reasonable number of houseplants remove significant quantities of pollutants in homes and offices. Indoor houseplants should not be over-watered because overly damp soil may promote the growth of microorganisms which can affect allergic individuals.

At present, EPA does not recommend using air cleaners to reduce levels of radon and its decay products. The effectiveness of these devices is uncertain because they only partially remove the radon decay products and do not diminish the amount of radon entering the home. EPA plans to do additional research on whether air cleaners are, or could become, a reliable means of reducing the health risk from radon.
