Dryer Vent Cleaning


The electric or gas clothes dryer makes our daily lives so much easier. However, it is easy to forget that drying clothes produces lint. Much of that lint is caught by the dryer’s lint trap. But not all of it. Some get to the vent tubing that carries warm air to the screened vent in the outside wall. That lint, not removed, can build up, creating a place for bacteria and mold to grow, and constituting a fire hazard. It also inhibits airflow, making the dryer work harder, increasing your utility bills.

We recommend cleaning your dryer tubing and vent regularly – typically every six months for a household of four to five people. Having our expert technicians come and clean your dryer vent tubing and wall vent ensures your dryer is working efficiently and any lint fire hazard is all but eliminated.

  •   I have dealt with this company on many occasions now, so I felt like it was time to write a review. If I was to write every detail about how great this company is then i would be here forever! The company I work for decided to get rid of our old a/c vendor due to the lack of communication & poor work, so I searched yelp & chose Diamond because of the great reviews & they definitely live up to them! They are very professional, do great work and have absolutely wonderful customer service. Diamond is so honest & don't try to get you for every dime you have, unlike other companies. We had our warehouse in Ontario seen to & they did such a great job I asked them if they were able to come out to our corporate office in Cerritos & they were more than willing to drive the distance to service us. Anthony would even call just to check up to see how our a/c was doing. Thank you Mike, Anthony & the rest of your crew. You are awesome!

  •   Will came out to clean our furnace and I was very pleased with how professional and helpful he was! I told him how my family gets allergies in our home and he went out of his way to check out the air system and found the culprit. He made sure all my questions were answered and clarified anything I didn't understand. I hope to have the pleasure of using him again for our next service.

  •   Our dryer vent goes straight up through the roof. We spoke with Anthony on Saturday to schedule our visit. We were scheduled  for Monday morning. He assured us that this would be the full cost with no pressure or add-ons.

    Tim was our technician and he arrived at 9:00 am. He was pleasant, professional, thorough, and quick. We are very happy with the service and highly recommend Diamond.

  •   Anthony was great. He was extremely responsive and explained the entire process in great detail. He was able to schedule an inspection for me the next day. When Paul the technician came out, he was extremely professional and patient with me, explaining how things worked and took pictures of my vents. In the end, I didn't need cleaning because my house is rather new. However, I was glad I still called Diamond Air to do a professional inspection because you never know. The previous tenant had a pet and I was afraid there would be dust, dander and pet hairs. I wouldn't hesitate to use their service in the future. Thank you!

  •   Diamond Air is an exceptional company to hire for you air duct and vent cleaning.  Will and his crew went above and beyond their duties.  Upon calling, I explained to Anthony what we needed and he was prompt to schedule us in.  Will, the service tech, and his crew were very professional and detailed with their work. They covered my furniture where the ducts were being cleaned.  In addition, Will noticed the there was a connection missing from my venting tube.  He went to Home Depot to get the part, however the part that was needed did not fit and Home Depot did not carry. Will suggested a company we contact with this issue. His crew stayed longer than needed. Pictures were taken before and after the cleaning. Will and his crew were kid friendly. Do not look further, this is the company to hire hands down. Thank you Anthony and your crew! We are very happy!

    Anthony saw the review and decided to refund me the credit card fee.  It was very nice of him to do that he honor his words.  I really appreciate it.  Thanks Anthony!

    Requested quote Diamond Air and Anthony replied my message fairly quickly.  Scheduled the service for today.  The crew came on time and very friendly.  The services was very quick and done a very nice job to clean the vents.  When the crew arrived they explained what is the procedure going to be.  
    The only thing I dont like was they charged 3% if you are using credit card. Which Anthony promised me over the phone will waived it but end up still charging me.

  •   First off, I was not paid for a review, nor did I receive a discount for providing one. My wife and I recently completed a remodel after a flood in our home. The company doing the repair did not cover anything during their work and we had dust everywhere. I came to Yelp looking for a duct cleaning service and found this company. Their reviews were awesome so I gave it a shot. The two workers arrived on time (a little before) their scheduled window and were a pleasure to work with. They were here for a majority of the day but it was no problem because of how thorough they were. They covered all furniture with plastic, cleaned up after themselves, and even cleaned up debris on the floor that they did not cause. As far as price, they are fair. Just remember you get what you pay for. I cannot express how pleased my wife and I were with them. FYI LEO, military, and senior citizens get a discount. Overall, great experience. Will refer to friends as family, as well as have their number stored, for future duct or AC services.

Frequently Ask Questions

Should a Dryer Vent Be Professionally Cleaned? 2017-06-30T13:20:37+00:00

Dryer vents should be cleaned regularly because dryer lint is both highly flammable and can exacerbate breathing conditions if it circulates in the home’s airflow. If you notice the dryer isn’t drying clothes as effectively as it used to, or if the outside of the dryer is reaching burning hot temperatures, it is a good sign that the dryer vent needs to be cleaned. For the majority of residential homes, a dryer vent should be cleaned once every year.

How is a Blower Motor Cleaned? 2017-06-30T13:20:02+00:00

The first step to cleaning a blower motor involves shutting off the gas and electricity to the furnace. Once these are off, the motor is removed and the unit is disassembled. This allows the technician to clean debris that is attached to the fan wheel and the housing. In most cases, this can be done using compressed air and a slightly damp cloth. Once the blower motor, fan wheel, and housing are cleaned, the unit is reassembled and tested prior to reinserting it into the furnace.

How Do I Verify the Reputation of the Cleaning Service? 2017-06-30T13:19:03+00:00

It’s a good idea to check the company’s standing with the NADCA and the local Better Business Bureau (BBB). You will also want to see proof that the company is properly licensed and carries the necessary insurance to cover any defects in the work they perform such as duct replacement. Finally, it’s advisable to seek recent references from clients in the community that have used the company’s services.

How Does a Rotobrush Vacuum Work? 2017-06-30T13:18:18+00:00

Diamond Air uses a roto brush vacuum system that dislodges dust and debris from deep within the system. First, the duct system is placed under negative pressure. As the vacuum sucks the air from the ducts, the brush dislodges debris that is attached to the interior surfaces of the duct. This debris gets picked up in the airflow and removed from the system. A Rotobrush helps improve the efficiency of the system and improve the air quality within the home.

Are There Health Benefits to Duct Cleaning & Duct Repair? 2017-06-30T13:02:26+00:00

If you are looking for a better life through the air you breathe, then cleaning your ducts is an essential step. Pollen, dust, pet dander, mold, bacteria, and other air contaminants can collect deep within ductwork and be circulated through the home. Further, duct repair can ensure proper airflow and eliminate points of entry where contaminants can make their way into the system.

What is the Air Scrubber Plus? 2017-06-30T13:20:57+00:00

Air Scrubber Plus pulls in water and oxygen molecules that ionized and released into the home’s atmosphere. These ionized molecules effectively destroy bacteria and viruses in the air. It is also highly effective against odors from pets, VOC’s, and other airborne contaminants that can exacerbate allergies and trigger breathing conditions.

Why AC Coil Cleaning Important? 2017-07-21T19:00:59+00:00

There are two coils within your air conditioner unit. The first is the evaporator coil. These absorb the heat and humidity from the air. The second are the condenser coils. This expels heat outside of the structure. In order for these coils to work properly, they must be clean. If they are not, their ability to perform their functions is diminished which causes the system to work less efficiently.

How Much Does Residential Duct Cleaning Cost? 2017-06-30T13:19:20+00:00

There are many variables that can influence the overall cost of duct cleaning services. These variables include the size of the home, the accessibility of the system, the regional climate, and the amount of contamination within the system. Generally, it can cost between $450 to $1,000 to clean most residential systems. The costs can be higher for commercial systems which are often quite larger and more complex.

Are Antimicrobial Chemicals Effective? 2017-06-30T13:18:33+00:00

Applying antimicrobial chemicals to the interior surfaces of the duct system will kill mold, viruses, and bacteria. In order for them to achieve maximum effectiveness, it’s necessary to thoroughly clean the system prior to application. This is a highly effective solution for homes that have sustained water damage.

How Often Should Ductwork be Cleaned? 2017-06-30T13:04:01+00:00

Generally speaking, every 2-3 years. However, if there is a smoker in the household, pets, or water contamination, it is advisable to do this more frequently. This is especially important if there is anyone in the home that suffers from respiratory conditions such as asthma, emphysema, or allergies. Further, it is advisable to schedule a duct cleaning following any remodeling/renovation projects.
