Professional Air Duct Cleaning

Because of our vast knowledge of building and HVAC systems along with our expertise in solving indoor air quality problems, we knew that creating an air duct cleaning division would be a great fit to our remediation and abatement services. Our state-of-the-art air duct cleaning services strictly adhere to all cleaning recommendations from NADCA (National Air Duct Cleaners Association).

Without the knowledge and experience that we bring to every job, it would be difficult to correctly perform this important service. There are many companies that offer air duct cleaning for $200.00 or less, and only spend an hour at your home. Please understand that a thorough and proper air duct cleaning requires upwards of two or three technicians working approximately 8-10 hours in order to clean a system in the average home. As mentioned above, we follow the NADCA ACR2013 standard; we even clean the evaporator coil which is a crucial step in the air duct cleaning process and not performed by more than 75% of air duct cleaners.

When Should You Seek Professional Air Duct Cleaning Services?

If you notice a large buildup of dust and debris at your HVAC diffusers/vents, or are experiencing respiratory symptoms in your home, you may need to contact a professional air duct cleaning service. When this happens, our team is very responsive and can have someone out there to investigate quickly.

Also, if you are a business owner or directly responsible for building maintenance in your office, school, or factory and receive complaints or suspect a problem, it’s best to contact a company that’s experienced in providing professional air duct cleaning services. Our team’s air duct cleaning service experience extends not just to residential duct cleaning, but offices, schools, libraries, multi-family apartments, factories, commercial kitchens, and more.

cleaning a dirty duct unit

What is Duct Cleaning

The National Air Duct Cleaners Association’s (NADCA) rule of thumb for consumers is that “if your ducts look dirty, they probably are,” and that dirty HVAC systems should be inspected by a reputable, certified HVAC professional. Below are some other reasons homeowners choose to have their air ducts cleaned.

Indoor Air Quality

Did you know that dirty ductwork can contain up to 40 pounds of dust (which is created annually through everyday home activities). Having your ductwork properly cleaned every few years can greatly improve indoor air quality within your home and actually reduce dust build-up.  If you feel that that air quality in your home causes allergies or other health effects, have your ductwork inspected to determine the cleanliness of the system; we offer free inspections to show our Clients what’s inside of their ductwork.  If you use a high-quality air filter you will maintain cleaner ductwork and better indoor air quality.

People living in their home are one of the biggest contributors of indoor contaminants; we generate dust, dander, chemicals and skin cells. These materials are re-circulated up to 7 times in a day.  This is what creates build-up within duct work.

Just because a building has dirty air ducts, this doesn’t automatically contribute to poor air quality within a building; however, it can contribute to larger health problems which may cause serious problems for people with respiratory conditions, allergies or autoimmune disorders.

Save Energy

Who Wants to Conserve & Save Energy?

The U.S. Department of Energy states that 25 to 40 percent of energy is wasted when used for heating or cooling a home.  Dirty ductwork will cause an HVAC system to work harder which will shorten the life of the system and use more energy.  The dirt and dust accumulation cause air turbulence within the ductwork (Law of Fluid Mechanics) which does not allow air to flow as freely and effortlessly.  Even if your system uses high-end filters with high MERV ratings, they can still become dirty over time.

The take-home message here is that if your HVAC system is properly maintained it won’t work as hard to maintain the desired temperature in which is set.  This results in less energy used and leads to improved efficiency and cost savings.

How should a residential HVAC be cleaned?

Per NADCA, 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. Stay away from contractors who use shop vacuums and are in your home for less then two hours. The average home requires a 3-man crew at least eight (8) hours to perform proper cleaning. If the price you get from a contractor seems too good to be true, you are wasting your money on ineffective duct cleaning.

Questions to ask to determine if your duct cleaner did a thorough job

  1. Was the entire heating and cooling system cleaned (drain pans, humidifiers, coils, fans, duct work, etc.)?
  2. Is the heat exchange surface visibly clean?
  3. Are both sides of the cooling coil visibly clean?
  4. Are the coil fins straight and evenly spaced (not bent and smashed together)?
  5. Is the coil drain pan completely clean and draining properly?
  6. Are the blower blades clean and free of oil and debris?
  7. Is the return air plenum free of visible dust or debris?
  8. Do your filters fit properly and are they the ones specified by your equipment manufacturer?
  9. Are the interior surfaces of the ductwork free of visible debris?
  10. Are registers, grilles, and diffusers visibly clean and firmly reattached to the walls, floor, or ceiling?
  11. Was the duct cleaning contractor at your home for at least 8 hours?

Our infant son tested high for lead last year, and EHC was the place consistently recommended for testing and lead abatement. For a few weeks, our home ended up looking like a biohazard zone as they sealed it up and then meticulously tested and removed any sign of lead in our 125+ year old house. Some portions of our home were removed, some were encapsulated, some were sand blasted and sealed. The attention to detail was really impressive. In the end we felt we could move back into our home without worry that it was damaging our child. A few months later and our son's lead levels have dropped to below threshold for lead poisoning (so much faster than doctors anticipated), and it's because of EHC. This was an expensive process, but it is very clear why. I would recommend them to anyone.

I have worked with EHC as a vendor on multiple jobs. Tony Klopp and the crews are organize and communicate with us before the job begins, so we are all on the same page. The site guys work extremely well with our drivers when on site. Job sites are clean and accessible for our drivers to get in and do their job.

E.H.C. provides top shelf service every time, all the time. From the estimating process through project completion the staff and support to the project is always superb. I have personally had multiple projects involving asbestos remediation with multiple lead site managers the most recent Alex Henriquez provided daily communications on project status and projected completion helping schedule the next steps in our projects. In the construction arena when finding quality contractors can be challenging E.H.C. sets the standard for a fantastic work experience.

Barb King (VP of Operations), Mark Andrechik (Inspector), Cathy Workinger (HR Manager/Office Administator), Wendy McCall (Estimating Administrative Assistant) ESPECIALLY, as well as the rest of the EHC team members I came into contact with have exemplified professionalism, promptness, compassion, and the highest quality in service for myself and my home over the past 10+ months at various times. Barb King directly responded to my every request and concern better than I could have asked for, and Mark went above and beyond to personally text me to discuss any concerns or questions I had about the Mold Test Results and Summary he provided. Mark and Barb King also continued to make themselves available to me for any questions long past the initial work had been completed and truly exemplified what every homeowner would hope to see and receive in quality of service amidst facing a crisis in their home.Though they may not be the “cheapest” option, rest assured you will thank your lucky stars for every additional cent you throw their way once you realize the outcome and peace of mind provided to you as a result. If you ask me, the peace of mind that you are receiving what you have paid for and more in and of itself is priceless...especially in these uneasy times through this pandemic.

This is the third time EHC has helped me with a problem and I couldn't be happier. This time Alex and his helper removed duct work with asbestos and did a fantastic job. Having asbestos is scary and these guys make it seem like an everyday occurrence. The office personnel are so kind and polite. This is a great company. Thanks EHC for your very professional, excellent work.

We contacted EHC, set up an appt and Mark came to visit and took readings. We suspected mold issues due to our Grandson was having a reaction every time he visited us recently. The testing indicated mold in our ducts. Art and Nelson came out and in 2 days the cleaning and treatment eradicated the issue. The whole process was seamless and we are confident it was totally taken care of.Art and Nelson were professional and courteous during this process, we couldn't have asked for more.

My experience with EHC Associates has been excellent. They have been so helpful from the moment I placed the first phone call to when I payed my invoice today. My family has been out of our house for remodeling for almost 2 months. When we were able to move back in it dawned on me that there was a chance that some of the old building materials that were removed could have contained asbestos. I called EHC to get my air tested to make sure it was safe for my family to move back in. I called on Monday and they were able to squeeze me in for the test that very same day. I paid to get my results expedited and I had the information back the next evening. The price was not outrageous either. Thank you EHC and a very special thank you to Wendy, Elio, & Cathy for being so friendly, professional, and informative. I am a supervisor for a customer service call center and I can tell you that they get an A+ in my book for the way they treated me as a customer!

EHC saved the day for us! During construction we encountered possible environment materials on our site. Because all of trades were lined up to do work on a very tight time schedule, I called EHC who sent a representative out within hours of my call. The rep took samples and by 2PM the next day I got a call with the results of the sampling (yea no hazardous materials!) thus allowing us to stay right on our construction schedule. Thank you EHC for saving the day!!!

I called E.H.C. with some questions about a property I'm buying. The person I talked to was very helpful and friendly. He basically told me that i don't need his services and went into detail to explain why. He really put my mind at ease about the purchase. I'm glad I don't need there help right now, but if I do, they'll get my business for sure!
