The amount of time it takes to clean a residential HVAC system depends on many variables such as the size of the home, the number of systems, the extent of the contamination and the number of HVAC cleaners performing the job. Ask at least two contractors to inspect your system and give you a time estimate for your particular system. This will give you a general idea of how long the job should take as well as an idea of how thoroughly the contractor plans to do the job.
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, such as mold, fungi, bacteria, and very small particles of dust. The removal of such contaminants from the HVAC system and home should be considered as one component in an overall plan to improve indoor air quality.
As one of the duct cleaners that do it right it disgusts me to hear the horror stories some of my past customers have had with the companies using scare tactics, bait and switch schemes, and just plain intimidation to make a fast buck. The Ductz franchise as a whole has gone behind other "duct cleaners" in the last year to the tune of almost three-quarters of a million dollars. All of this expense could have been avoided had the customers been able to do some background research before hiring. NADCA is a great organization and should be a minimum requirement for finding a duct cleaner. Other great questions include "How long does the service take?" (2 techs, 4-5 hours for a small house, 7-9+ hours for a two system house), "Do you clean the entire system including all trunk lines and the air handler (blower motor and evaporator coil)?", "How do you validate the job you have done?" (before and after picture reports work great). Beware of duct cleaners that say their process will solve all your air quality concerns. Duct cleaning is one of several steps to take to rid your home of unwanted dust, dirt, mold, and other allergens.
Have you been hunting for an expert air duct cleaning service but nothing has worked out for you thus far? Maybe you have been flipping through the Yellow Pages for hours but you still have yet to find what you are looking for. Are you spending your time thinking of “where shall I find an expert service? Is it possible to find such a service near me?”
Had our ducts cleaned late April, 2016. Sodium Chlorite was sprayed into ducts after cleaning. Ever since, we have been bothered with eye and nasal passage irritation because of a “chemical” and “musty” odor. This odor is present whether or not a/c is on.) We are told the sodium chlorite (“EnviroCon, manufactured by Bio-Cide International) is used in hospital and nursing home settings and is not hazardous to health. The air duct company’s suggestion is that they come out and spray even more sodium chlorite…we absolutely don’t want this done! Have had various other recommendations about what we need to have done to remedy our problem. We will be unable to stay in our home if a resolution cannot be found. We’d be willing to replace the ductwork if necessary. (One professional suggested that the cleaning may have “knocked something loose” inside the ductwork and that is the source of the irritant.) This home was built in 1920…no idea when the present ductwork was installed. Any suggestions would be appreciated.
Most people are now aware that indoor air pollution is an issue of growing concern and increased visibility. Many companies are marketing products and services intended to improve the quality of your indoor air. You have probably seen an advertisement, received a coupon in the mail, or been approached directly by a company offering to clean your air ducts as a means of improving your home's indoor air quality. These services typically — but not always — range in cost from $450 to $1,000 per heating and cooling system, depending on:
