Frequently Asked Questions
First of all, we have been cleaning air ducts since 1969. We are a nationally recognized industry leader. We have been training air duct cleaners internationally since 1984. Our experience and reputation speak volumes.
Second, we actually clean your entire air duct system including the furnace blower compartment. And how do we know it’s clean? We show you and document the cleaning with digital photos!
Third, we educate you about your system and how we are doing your cleaning. We believe that is part of why you hired Safety King. Because most people are not familiar with the workings of their air duct and HVAC system many of our competitors take advantage of that.
Almost all of our competitors try to make it appear they charge less than we do which would make sense because none of them do everything that we do. But many of them actually charge more than we do after they add fees for things like additional vents and access panels. They do not have the equipment and certified team that we have. The technician team we have assembled, trained and certified by Safety King and NADCA, uses cutting edge tools and methods for cleaning (Source Removal). All of our technicians take as much time as required to deliver a thorough and complete cleaning every time. We accept nothing less than a complete and thorough cleaning for every customer. Period.
We quote a fair and upfront price for our services. If you’re like most of our customers, you’ll come back to us again and again as the years go by, because you will have the first-hand experience of getting a job well done by Safety King.
Don’t be fooled by $39.95 or $79.95 “Whole House Specials”, which at least gets you poor work by poorly trained and unlicensed/uncertified people and at most bait and switch. Try this. Call a few heating and cooling contractors and ask them who does the best job cleaning ductwork in this area. They’ll probably tell you it is Safety King.
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 and debris. 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.
Will heating, ventilation, and air conditioning (HVAC) system cleaning reduce our home energy bills?
Research by the U.S. EPA has demonstrated that HVAC system cleaning may allow systems to run more efficiently by removing debris from sensitive mechanical components. Clean, efficient systems are less likely to break down, have a longer life span, and generally operate more effectively than dirty systems.
The most effective way to clean air ducts and ventilation systems is to employ Source Removal methods of cleaning. 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 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 ducts to the vacuum, which removes it from the system and the home.
Frequency of cleaning depends on several factors, not the least of which is the preference of the home owner. Our experience has shown that most homes warrant a full system cleaning every 3-5 years. Some of the things that may lead a home owner to consider more frequent cleaning include:
- Recent construction or remodeling work
- Smokers in the household
- Pets that shed high amounts of hair and dander
- Water or smoke damage to the home or HVAC system
- Residents with allergies or asthma
Use the following pre-qualifications:
- Make sure the company is a member in good standing of the National Air Duct Cleaners Association (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 technician doing the work holds a NADCA certification 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 if possible.
There are a variety of factors that could affect the time needed to clean a residential HVAC system, including the type of home, accessibility of the ductwork, and the number of workers on the project. A typical three or four bedroom home typically requires 2 to 4 hours for cleaning using Safety King’s state-of-the-art source removal techniques.
The best way to determine if the HVAC system cleaning was effective is to perform a visual inspection of the system before and after cleaning. If any dust or debris can be seen during the visual inspection, the system should not be considered clean. You can perform your own visual inspection using a flashlight and mirror in your vents, but a professional cleaning contractor should be able to allow you better access to system components and offer the use of specialized inspection tools. In addition, following this post-cleaning check list can help to ensure a top quality job.
A thorough visual inspection is the best way to verify the cleanliness of your heating and cooling system. All portions of the system should be visibly clean – i.e., such that you cannot see any debris with the naked eye. Have the contractor show you the following areas in your system after the cleaning work to verify that the job was performed satisfactorily:
|General||Did the contractor clean the entire heating and cooling system, including ductwork and all components?||YES||NO|
|Heating||Is the heat exchanger surface visibly clean?||YES||NO|
|Cooling||Are both sides of the cooling coil visibly clean?||YES||NO|
|Components||If you point a flashlight into the cooling coil, does light shine through the other side? (It should if the coil is clean.)||YES||NO|
|Are the coil fins straight and evenly spaced (as opposed to being bent over and smashed together)?||YES||NO|
|Is the coil drain pan completely clean and draining properly?||YES||NO|
|Access Doors and Covers||Are newly installed access doors attached with more than just duct tape (i.e., screws, rivets, mastic, etc.)?||YES||NO|
|With the system running, are all access doors or covers tight (no air leaks)?||YES||NO|
|Plenums||Is the return air plenum free of visible dust or debris?||YES||NO|
|Do filters fit properly and are they the desired efficiency?||YES||NO|
|Is the supply air plenum (directly downstream of the air handling unit) free of moisture stains and contaminants?||YES||NO|
|Blower||Are the fan blades clean and free of oil and debris?||YES||NO|
|Is the fan compartment free of visible dust or debris?||YES||NO|
|Metal Ducts||Are interior ductwork surfaces free of visible debris? (Select several sites at random in both the return and supply sides of the system.)||YES||NO|
|Fiberglass Duct Surfaces||Is the fiberglass material in good condition (i.e., free of tears and abrasions; well adhered to underlying materials)?||YES||NO|
|Air Vents||Have your air vents been firmly re-attached to the walls, floors, and/or ceilings?||YES||NO|
|Are the air vents visibly clean?||YES||NO|
|System Operation||Does the system function properly after cleaning?||YES||NO|
