At Duct Diagnostics, we understand that clean air is essential for a healthy home. Our Residential Duct Cleaning service removes harmful dust, allergens, and debris from your ducts, improving both comfort and indoor air quality. With our expert cleaning, your heating and cooling systems operate more efficiently, ensuring a safe, fresh environment for your family. 
The condition of your duct system directly affects the overall air quality within your facility. Over time, airborne particles including dust, dander, and chemical residues settle inside ducts and can negatively influence occupant health. We deliver expert duct cleaning services to commercial facilities, relying on specialized training and proven processes to achieve dependable and effective results. 
Dryers are critical to homes and businesses, yet they pose a significant fire risk without proper upkeep. Clogged dryer vents, filled with lint and debris, are the leading cause of over 2,900 fires annually. Our dryer vent cleaning service ensures safe airflow, preventing fires and boosting your dryers efficiency and longevity. 
Using the innovative Aeroseal technology, we offer a reliable and cost-effective solution to duct sealing. This method, created at Lawrence Berkeley National Laboratory, uses a calibrated fan and aerosolized sealant to seal hidden leaks. The result is improved air distribution, lower energy bills, and a more comfortable living or working environment.

I recommend Duct Diagnostics. I run a heating and air-conditioning company and refer all of our customers over to Ralph and Tim at Duct Diagnostics. Ive worked with these guys on commercial duct cleaning projects, as well as residential duct cleaning projects. All of their team members from the sales staff to the field employees are great.
We are very pleased!

The 3 man cleaning crew was knowledgeable, courteous and professional.
Wherever the worked they cleaned up after themselves
I thought the $2,850 price was excessive but I have nothing to compare it to
I need to wait a week before I can judge the effectiveness of the cleaning
I was shown pictures of the duct interior and they appear cleaner

Excellent work by Jim, Vince and Bailey (hopefully I spelled that correctly). Couldn't be more pleased with their professionalism and efficiency at doing their job. Showed real respect and care for my home as well. I was a bit of a skeptic at first if the result would be worth the above average investment but I'm amazed at the results. The before & after doesn't lie. There will always be dust and trash in my life but to know that at one point in time my duct work is clean and starting relatively fresh brings me and my family a great relief and peace of mind.

Duct Diagnostics did a fantastic job cleaning my HVAC system. What really stood out was their honesty after inspecting everything, they told me my system was in great shape and probably wouldnt need another cleaning for another 5 to 7 years. That kind of transparency is rare.
Before choosing them, I had gotten quotes from other companies that were either suspiciously low or ridiculously high and many were pushy and unprofessional. Some showed up late, pressured me into scheduling on the spot, or even left a mess behind after the job.
Duct Diagnostics was the total opposite. They arrived on time, explained every step clearly, took all the necessary precautions to do the job right, and left my home as clean as they found it. Friendly, professional, efficient exactly what you hope for.
Ill definitely be using them again and recommending them to others!

From the beginning, everyone on the Duct Diagnostics team were a pleasure to work with. The team that Ralph sent over to clean our ducting was professional, knowledgeable and personable. Jim was very thorough in explaining what would be done. Jim, Janel and Leo were hard working throughout the entire procedure. During the cleaning, we were informed several times about how things were progressing. We received before and after photos of the ductwork. They cleaned up beautifully afterwards. We highly recommend this company due to their outstanding work .
