Question: Are there any health benefits that come from HVAC system cleaning?
Answer: 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 an important component in an overall plan to improve indoor air quality.
Question: Will HVAC system cleaning reduce our home energy bills?
Answer: 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.
Question: How should a residential HVAC system be cleaned?
Question: Are truck mounted vacuums or portable vacuums better for cleaning ducts?
Answer: The NADCA does not endorse one kind of equipment over another and there are reason where one may be more convenient to operate that the other for a particular duct cleaning project . There are two main types of vacuum collection devices: (1) those mounted on trucks and trailers, and (2) portable units. Truck/trailer mounted equipment is generally more powerful than portable equipment. However, portable equipment can often be brought directly into a facility, allowing the vacuum source to be located closer to the air duct work. Both types of equipment will clean to NADCA air duct cleaning standards.
It is very important that the duct cleaning company attach whatever system they are using to a collection device for safe containment prior to disposal. Any vacuum collection device which exhausts indoors must be HEPA (high efficiency particulate arrestance) filtered.
It is important to note that a vacuum collection device alone will not get an HVAC system clean. The use of methods and tools designed to agitate debris adhered to the surfaces within the system, in conjunction with the use of the vacuum collection device(s), is required to clean HVAC systems. (For example: brushes, air whips, and “skipper balls.”)
Question: How often should residential HVAC systems be cleaned?
Answer: The frequency of cleaning depends on several factors, not the least of which is the preference of the home owner. Some of the things that may lead a home owner to consider more frequent cleaning include:
- Smokers in the household.
- Pets that shed high amounts of hair and dander.
- Water contamination or damage to the home or HVAC system.
- Residents with allergies or asthma who might benefit from a reduction in the amount of indoor air pollutants in the home’s HVAC system.
- After home renovations or remodeling.
- Prior to occupancy of a new home.
Question: What is the normal price range for the air duct cleaning service?
Answer: The Environmental Protection Agency says that “duct cleaning services typically (but not always) range in cost from $450 to $1000 per heating and cooling system, depending on the services offered, the size of the system to be cleaned, system accessibility, climactic region, and level of contamination” and type of duct material.
Your system may have a special issue and we will do a full assessment of your system in its environment. VentTec will provide you with a price quote before any work is done.
Consumers should beware of air duct cleaning companies that making sweeping claims about the health benefits of duct cleaning – such claims are unsubstantiated. Consumers should also beware of “blow-and-go” air duct cleaning companies. These companies often charge a nominal fee and do a poor job of cleaning the heating and cooling system. These companies may also persuade the consumer into unneeded services with and/or without their permission.
In fact if you have knowledge of a practicing “blow-and-go” air duct cleaner, contact your local Better Business Bureau to report the company, and your local, federal, and state elected officials to demand legislation. We would appriate this as these “blow-and-go” companies give reputable air duct cleaners a bad name. You help all consumers by reporting this.
Question: What criteria should I use in selecting an HVAC system cleaner?
Answer: Interview as many local contractors as you can. Ask them to come to your home and perform a system inspection and give you a quotation. To narrow down your pool of potential contractors, 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.
- Inquire whether the company is in good standing with your local Better Business Bureau.
- 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 “low cost whole-house air duct cleaning 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 other people if possible. In fact VentTec will be happy to provide you with references.
