General FAQs

Studies have shown that the indoor air can be up to 2 to 10 times MORE polluted than the air outside your front door. Most disposable filters remove about 10% of these pollutants allowing 90% to enter your air system, even during the construction of a new home. These pollutants contain dust, pollen, mold spores, human dander, dust mites, animal dander, construction debris, dead animals, fecal matter and much more. These materials collect in the furnace, air conditioner, condensing units, and within the duct surfaces, just as they do on furniture, bedding, counter tops and the floor surfaces. These areas are usually cleaned often, but the duct surfaces are hidden from view and can only be reached with specialized cleaning equipment. These pollutants can migrate out into the room and open areas again, or become a food source for mold and bacteria. These can all thrive in these dark comfortable environments, which contain high amounts of humidity or moisture from the air conditioner or humidifier. Biological growth can release mold spores or toxins into the entire HVAC system. Which can be distributed throughout your home though the air system.

“Dirty HVAC systems can spread airborne particulates and microbial pathogens throughout an entire home, building and work place,” reported Ed Chambers, President of ec2. “The end result leads to complaints, headaches, allergies, dizziness and severe respiratory problems. In the work place it has led to less productive employees, sick employees and even lawsuits. Infections from bacteria like Legionella and fungal lung infections such as aspergillosis all occur from breathing microbial contaminants.”

All indoor air was once outside air, so all of the dust, chemicals, pollen, insects and mold spores in the outside air can be pulled into the air system. People shed millions of tiny dead cells every hour. Cooking smoke, household insect sprays, personal care products, are also sources of indoor pollutants. Construction materials or remodeling activities, as well as many types of dust are produced only to find their way into the duct work. If duct components were stored in the outdoor elements prior to installation, they have collected or subject to dust, rain water, mold, rust, animal urine and feces, all prior to actual installation inside your home.

Why mold growth is detrimental to your home and you and your families health.

Mold spores are supported by a stable temperature, a food source and moisture to live and reproduce. Dust, dirt and other organic particles that travel throughout the ducts are all good sources of food for these spores to flourish. Your furnace and your air conditioner units are fully designed to maintain a comfortable temperature. The condition within the HVAC system, humidifier in the furnace creates and maintains a humid environment, which are perfect conditions for the growth of these spores. Humidity is available from conditions in the environment, humidity from the heating coils in the furnace and the cooling coils in the air conditioner. Live molds can release spores that will trigger allergic or asthmatic reactions, sometimes severe, in about +- 15% of the population. Mold both living and dead can produce toxins that may cause short term allergic reactions. Long term exposure of “some” types of mold toxins can result in permanent chemical sensitivity to common compounds in the environment. Since many people in the same household have different sensitivities, their reactions may all vary to different extents. Persons with sensitivities already will continue to have reactions, which will continue to get worse.

Depending on the amount of contamination and the location of the contamination, energy consumption could drastically increase. If the fan blades are old and encrusted with layers of built up dirt, evaporator coils and any other components are contaminated, may cause the system to run longer to cool and heat the required space you are trying to control. Heating and air conditioning companies will usually come out and change a filter and make sure the system is working. But, they do not check, nor do a thorough inside the ducts, furnace or condensing unit cleaning and remediation.
There are 3 major parts to the air system:

1. The supply and return grills

2. The interior surfaces of the return vents

3. The furnace and air conditioner handler

All 3 components of the system must be cleaned. If only two of the components are cleaned, the components of the 3rdone will rapidly contaminate the others that were cleaned.

This answer is not usually the same for everybody. Generally, if a system has been properly cleaned it should last for between 2 – 5 years. But, this is only if the system is properly maintained. The types of filters are also important. Store bought filters will filter out a much less amount than high arrestance filters, which will stop up to 90% of the airborne contaminants. The location of your home is important also. If you live near a highway, busy streets, congested areas with a lot of traffic all add to the contamination of the air which could eventually works its way into your home. Household where person are extra sensitive, allergies, asthma, respiratory issues are all factors which help determine the frequency of system cleanings.
The cost to clean is determined on how many ducts, how many furnaces, how many outside condensing units and usually the dryer vent would be cleaned out at the same time. It is also determined by how dirty the system is, how long it has been since the last cleaning, if ever? The location of the furnaces, ducts and the outside condensing units are also factors. If there are repairs which are needed, this will also play into the total cost. The purchasing of new custom fit, high arrestance filters may be recommended, which also add to the overall total.

HVAC – Air System Cleaning & Remediation

Actual work specifics:

Supply and return grills, if painted over are carefully removed by utilizing a razor blade to cut the paint and allow us to carefully remove the grill or return from the wall. It is very possible that a chip may occur, but we are as careful as possible. If you have paint, we will be more than happy to do a quick touch-up. We are not painters, but we will do our best. If you like, we will leave alone and you can have your painter do the touch up. But this is not at our expense. These grills are taken outside and carefully cleaned by hand. Then when we are finished, they are then returned to their rightful place.

Interiors’ surfaces of the supply and return vents are aggressively agitated by stiff, but flexible nylon bristles, which scrub the inside of the ducts, dislodging all of the years of caked on contaminants. As the contaminants are dislodged and rendered airborne, the Dual HEPA Filtrated vacuum system is extracting all of the dislodged airborne debris into its double filtered waste tank. This particular process is completely self contained and is surprisingly a clean process for what it is actually accomplishing.

Furnace and air conditioning units are disconnected from their power source to start. The blower and motor assembly are removed from their housing and then taken outside. The motor will be blown out with compressed air, then completely cleaned and detailed to remove all of the encrusted debris amongst the blades and unit. Inside the furnace box, the inside of the box is completely detailed and the heating coils are also thoroughly cleaned. The motor assembly is then reassembled, reinstalled and then tested, prior to finishing.

Will this work eventually save me money?

It’s not guaranteed, but it makes sense that it will. By cleaning all of the mechanical components, cleaning out the contaminants and making sure that the unit is running at its optimum ability? With proper maintenance, higher rated arrestance filters and regular system cleaning all should contribute to a more efficient, cleaner, less contaminated, Healthy Home.

Healthy Home Cleaning

The air system is a big part of the “Healthy Home” concept. Carpets, upholstery, area rugs, fabric wall coverings and leather items are all soft and pores surfaces which should also be cleaned and maintained on a regular basis. One can never make the perfect environment, but there are many different steps you can employ to make your environment healthy for you and your loved ones.
