Q? What is involved in the CLEANING PROCESS of my INDOOR AIR?
According to NADCA, the most effective way to clean air ducts and ventilation systems is to employ source removal methods of cleaning, which means we aggressively remove all debris from your air system. This requires a contractor to place the system under negative pressure, through the use of a specialized, powerful vacuum. While the vacuum draws air through the entire ventilation system, devices are inserted into the ducts to dislodge any debris that might be stuck to interior surfaces. The debris can then travel down the ventilation system to the vacuum, which removes it from the system and the home.
Power Vac cleans using a special truck-mounted vacuum system and compressed air power brush to remove all the dust, dirt and debris from your HVAC system. Our truck-mounted vacuum is an engine that ensures maximum suction on each and every job. From the truck, 8″ vacuum hoses are attached to each main line (supply and return) as we use a 200 psi compressed air power brush (or electric brush) and whipper system to thoroughly clean the entire air handling system. We also remove your furnace fan and clean it and all the internal components of your furnace, such as burner, heat exchanger and A/C evaporator coil.
We seal and block every vent (register and grill) to increase negative pressure by the push/pull method. All the dust, dirt and debris is guaranteed to be removed from your entire system.
Q? What is in my HOME’s AIR?
Remember the last time you saw sun beaming through a window? The visible particles that dance in a sunbeam, amount to about 1 percent of all particles in the air. That leaves 99 percent too small to be seen with an unaided eye. The effects of these invisible pollutants may be seen when it is too late – after a film has covered your walls, furnishings and draperies and in human discomfort. Cleaner air, whether indoors or outdoors, is more important than ever. Power Vac has over 40 years of experience in improving indoor environments.
We specialize in cleaning dust from your heating, ventilation and air conditioning (HVAC) system so you and your family enjoy cleaner air in your home. Most IAQ problems and HVAC inefficiencies are brought about by the activities within the home itself; pets, carpeting, insulation and the effects of construction and renovation. The best and most economical solution is servicing your ducts and furnace on a regular basis as part of your maintenance program, on a schedule that is appropriate to each individual system.
Q? What are the BENEFITS of Cleaning my INDOOR AIR?
A building’s heating, ventilation, and air conditioning (HVAC) system provides conditioned air to occupied spaces within the facility. Typically, air from within an occupied space, along with fresh air drawn from outdoors, is drawn in through ductwork to an HVAC unit, where it is conditioned. Before the air gets to the unit, it usually passes through a filter designed to protect the mechanical equipment from becoming contaminated by large particles of dust and debris. Many filters commonly used today will not prevent the introduction of small particles of dust and debris from the air stream into the system. Over time, these deposits may form sizable accumulations.
Heating, ventilation, and air conditioning (HVAC) systems have been shown to act as a collection source for a variety of contaminants that have the potential to affect health. These contaminants include mold, fungi, bacteria, and very small particles of dust.
Cleaning lessens the likelihood of indoor air pollution in the building, and may help to alleviate health and comfort complaints by occupants.
Clean HVAC systems perform more efficiently, which may decrease energy costs.
Well maintained mechanical components are likely to last longer, reducing the need for costly HVAC system replacement or repairs.
The removal of such contaminants from the HVAC system should be considered as one component in an overall plan to improve indoor air quality.
Since ordinary cleaning is not able to reach the very deep inside of the air ducts, only professionals with special equipment can help you thoroughly clean up the air conditioning system.
Q? Why Should I worry about the QUALITY of my INDOOR AIR?
In order to maintain acceptable indoor air quality (IAQ), cleaning HVAC systems provides many benefits. Cleaning lessens the likelihood of indoor air pollution in the building and may help to alleviate health and comfort complaints by occupants. With growing awareness of the dangers of indoor air pollution and sick building syndrome, public concern for the cleanliness of ventilation systems has led to a significant increase in demand for HVAC system cleaning services.
IAQ can be defined as the measurement of air as it affects the health and well-being of building occupants. People spend up to 90 percent of their time indoors. The amount of time spent indoors is a great concern, given the fact that studies conducted, show indoor pollutant levels may be 10 to 100 times higher than outdoor concentrations.
The economic benefits of solving IAQ problems can also be significant. Improving air quality can reduce worker absenteeism and increase productivity. The government estimates that absenteeism cost more than billions of dollars a year in lost productivity and medical costs, and medical researchers have found that 50 percent of absenteeism is due to upper respiratory problems, which is a common symptom in sick buildings.
In most cases HVAC system cleaning alone will not solve IAQ problems. Solving IAQ problems requires a team of professionals, such as mechanical contractors, filtration experts, test and balance specialists, and, of course, professional HVAC system cleaning contractors. It can, however, greatly reduce the threat of indoor air pollution when performed in conjunction with a program of regular building maintenance and IAQ evaluation.
Q? How do I choose the right duct cleaning service provider?
You should interview as many local contractors as possible. To narrow down your pool of potential contractors, use the following pre-qualifications:
- Make sure the company is a member in good standing of NADCA.
- See if the company has been in business long enough to have adequate experience.
- Get proof that the company is properly licensed and adequately insured.
- Verify that the company is certified by NADCA to perform HVAC system cleaning.
- Make sure that the company is going to clean and visually inspect all of the air ducts and related system components.
- Avoid advertisements for “$99 whole house specials” and other sales gimmicks.
- Ask if the company has the right equipment to effectively perform cleaning, and if the company has done work in homes similar to yours.
- Get references from neighbors if possible.
