“Guarantee Air Duct Cleaning completed the service in an exceptional and timely manner. I highly recommend for them for HVAC cleaning.”

“Great Job! We had our ducts cleaned by Guarantee Duct Cleaning while away on vacation in Mexico. Upon returning home, I immediately noticed how much cleaner the air in the home was! Thank you for doing such a great job!”

Drew Bledsoe

NFL Quarterback Legend

“Having our office ducts cleaned with the RamAir system was a very positive experience… no dust escaped into the building during the cleaning, and we’ve noticed an extraordinary difference in our air-quality.“

Nancy P. Walter

Manager – AAA Headquarters in Bend, OR

“Having worked in the HVAC industry for many years, I can attest that typically the trunk lines of a duct system hardly have any dust and debris in them, the bulk of it is in the supply lines.

By cleaning the ducts with a negative air truck, you’re pulling the dust and debris from the supply lines into the trunk lines, which makes no sense.

Guarantee Duct Cleaning’s system is far superior.”

Chris Helm

Veteran Service Technician, Deschutes Heating & Cooling, Bend, Oregon

Wow Oh Wow!!!! My husband and I were so impressed today by the workmanship, professional and friendliness that Dakota showed while cleaning our furnace air ducts and dryer vent. He worked extremely hard the entire time he was at our home. He was so nice and friendly, I felt very comfortable having him in our home. He explained everything in full detail and never seemed bothered by any questions we had. I would definitely hire this company again and again! I will refer all my friends and family... to Guarantee Air Duct Cleaning. Kudos to Dakota for doing a fantastic job today! Thank You! Terri & Bob Nortonread more

Dakota, the technician, did a fantastic job. He was knowledgeable, friendly and very hard-working. David, the owner was helpful and offers a great price for his services. I will be a repeat customer, for sure, and next time will schedule sooner, as my ductwork was in dire need of cleaning.

The team at Guarantee Air Duct Cleaning was beyond thorough for every step of this job—from the owner who took care and time to call meafter a long day to explain the process of duct cleaning—to the skilled technician who worked diligently to access my house with his cumbersome equipment —even when faced with unexpected obstacles blocking the driveway of my property.Often one part of a business is exceptional. This wholeteam was exceptional—working together to clean the entire duct system... in my house which had been neglected for many years prior to me purchasing the home.As a business owner, I value exceptional service and will gladly take my time to commend such service! Thank you cleaning team! It’s going to be nice to breathe clean air!read more

I have been so frustrated with the constant dust on everything in my house no matter how much I dusted. I finally got around to getting my ducts cleaned and no more dust! I also think my airflow is better - I know it’s not a guarantee of the service but it definitely feels like air is moving around better and I’ve been able to bump up my AC temp a few degrees without having a hotter house.The tech was great, courteous, and friendly. He had to take a shelving unit down to access the furnace and... he put everything away exactly as he found it.If you’re looking to clean your ducts, I highly recommend Guarantee Air Duct Cleaning.read more

David from Guarantee Duct Cleaning sent out his employee Dakota last Friday to clean my house ducts. I cannot say enough about Dakota! He explained everything that he was going to do and proceeded to perform his task. He was efficient and kept everything neat and in it’s place. He was professional and kind. Can’t recommend this company enough!

I had a birds nest in my dryer vent which is about 30 feet up. Every other company put me 2 weeks out. I called Guarantee and they came same day! I’m so grateful they did, there was a lot of combustible dry twigs in there and now I can use my dryer. Thank you David!!!

I adopted an 8 week old kitten named Boots. I placed him in the bathroom to give him a safe quiet place. When I returned to check on him he was gone! I panicked! He had crawled through the holes under the cabinet and gone down the heating and A/C duct.I called several people who were no help at all. It was later in the evening when I called David. I told them the story and he came and went under the crawl space and opened the duct so he could get out. The next morning the kitty showed up.... David called to find out about Boots and I told him he was back. David came out an reattached the duct work for me at no cost! David is a great human being in my book and so very much appreciated! A man who loves animals is extra special in my eyes.David and I agreed the kitty's name should be Houdini!!!Lol!Thanks again David , we need more people like you in the world going beyond the call of duty! May it be returned to you 10 fold!Sincerely grateful,Yvonneread more

I am soo impressed with David (the owner) and his staff. They were on time, did a beyond thorough job AND came back twice because 2 ducts were missed (my fault). I had our ducts cleaned 2 years ago and they weren’t as thorough. The amount of stuff that came out of this cleaning was shocking….floor pieces from the original build of the home from 20 years ago, amongst other things!

A truly professional experience! The tools and technology used allowed for a thorough dryer vent cleaning while keeping the house and surrounding area clean. The owner was super professional and knowledgeable about the process and even shared how his proprietary tools worked. He was professional, knowledgeable, and friendly. I would highly recommend their services and look forward to working with them again.

Dave, the Owner, and Steve, who did the cleaning, explained, scheduled , and efficiently cleaned our ducts after 17 years (first time) before installing a new HVAC. It's a worthwhile maintenance event, and they are priced right and experienced! Great upbeat people, professional and pleasant. Dave followed up with a call. Would definitely recommend!

We contacted David, cool dude, who set us up with a fair price and an excellent technician (Nick) who showed us before and after cleaning pictures of our HVAC ducting in our brand new house. The difference after the cleaning the ducts was miraculous, we noticed cleaner dust free air the very next day. All the construction debris, sawdust, dirt and drywall powder is no longer being blown around our home. This is a health, quality of life service that is worth every penny and you will breath... fresh air instead of construction pollutants. Thank you David and Nick for a job well done.Aloha, G & Mread more

Incredible service from an incredible team. They serviced a rental in short order with great communication and the result was amazing such that I thought they replaced the duct with a new one. Proud to have this local business serving Bend. Cannot recommend them highly enough.

What can I say, David and his team were responsive, courteous, accommodating and got the job done.First, when I called to get an idea of what it would cost to get both our home and our rentals ducts cleaned they actually answered the phone! I called several places for quotes and David was the only one to actually pick up the phone. Secondly, they made the pricing so easy to follow and it was extremely fair. When Nick arrived to clean the ducts he was very professional, arriving on time and... doing a quick walk through to confirm where everything was and making sure I didn’t have any questions. They got right to work and completed everything in a timely manner without issue.In short, I would highly recommend David and his team!read more

David & Andrew arrived on time - after a check-in call first to let me know they were on the way (so thoughtful!) - and went to work cleaning out the ducts in my new construction so that I would start off on the right foot with uncontaminated air. They were fast, efficient, AND neat! Not to mention very personable. Great service! I highly recommend.

We were very pleased with the professionalism and courtesies that this company brought to our home. They were punctual, clean and did a wonderful job. We had quite a few questions about the condition the furnace was in since recently purchasing the home. The technician answered all of our questions with confidence and had options for us to make any decisions. He also was very patient with our 4 dogs who were very interested in everything he was doing, and seemingly never leaving him alone! ... We will definitely be using GUARANTEE again for all of our HVAC needs. Nice to have a company actually live up to their name! Thank you.read more

David and his crew were professional, friendly, responsive and informative. We had a bad smell in one of our ducts and they inspected not only the suspected location of the smell but the whole system. They explained everything they were doing before they did it so we knew what to expect as results. They ended up cleaning our entire system and then sanitizing it and they were very careful to clean up after themselves as they went through the house. I would highly recommend them!

Nick did a great job on our vents. He must have removed 2 lbs. of dust and lint from our dryer vent. He also removed marbles, rocks, and super hero cards left by the previous owners. He was cordial and knowledgeable about the process and was thorough in the process. The return air vent was remarkably clean. We’ll use them again for our next vent cleaning.

Nick was very professional and knowledgeable. He did a phenomenal job cleaning the dryer vent. He was also able to vacuum out debris left from the previous owner. They did not have an attachment to clean the side vent under the kitchen sink baseboard because it was perpendicular to the floor rather than vertical. Nick was personable and cordial and provided us any and all recommendations. We would use this company in the future.

What an amazing company! I had called for duct cleaning and spoke to the owner in detail regarding some other issues I had in the new home my husband and I purchased regarding some “odd” smells. David spent a very long time with me on the phone, and even went over to my house to do a thorough inspection just to help. He is still continuing to work with me and guarantees we will get our “smelly situation” handled no matter what. Very professional, friendly, knowledgeable. I highly recommend!

Guarantee Air Duct Cleaning cleaned our ducts February 1. Three months later we are STILL thrilled with the work. Wiping down my kitchen cabinets used to be at least a two hour task due to the sticky powder. The other day it took me 30 minutes!Each person working was professional, thorough and friendly.

What a pleasure doing business with Guarantee! Nick was the tech. He called when he was on his way, showed up on time, and was so thorough with the cleaning! He was here 3 hours! You would not believe the amount of dust and gunk that came out of our vents! We bought this house over 3 years ago and the vents were not cleaned before we moved in - if ever! With 3 beagles, we have lots of dog hair and dander and I have allergies so I'm just relieved that we got this done. I am so impressed... with the level of service I received from this company. Highly highly recommend them! 5 star plus!!!read more

Nick was on time and got right to work on cleaning our heating ducts and dryer vent. He was careful working around furnishings. A professional and a gentleman explaining any questions I had. I was amazed to see what came out of the ducts. Definitely needed a cleaning. When the job was done, Nick vacuumed up his work areas to ensure it was clean. I Highly recommend Guarantee Cleaning Services.

I had Guaranteed vacuum out my air ducts because I was really struggling with indoor air quality and allergies, particularly since the heating system has been running more frequently. That night I immediately noticed a difference in my sinuses and in the quality of my sleep.I would run an air cleaner in my bedroom and had middling results, but getting them professionally cleaned was the ticket. I would definitely recommend having these guy doing this for anyone who has a forced air heating or... cooling system. David was also really responsive and easy to work with.read more

David is so awesome. He came out within minutes of me calling him for help! Our house was filled with the smell of dead mice that had died in our heating vent system and no one else was able to provide the professional and timely service that David was able to do. He also came that same evening (after hours no doubt) which shows how much he cares. Above and beyond service. Also, his prices are astonishing affordable. My roommate who runs rental properties can attest to his abilities,... professionalism and great cost. She has switched to using him for her rented homes as well.read more

Utilized Guarantee Cleaning for central air duct cleaning and disinfecting. Scheduling was responsive and professional. The Technician was on time (w/in 30 min window given) and the service was very professional and personable. For my 1400 sq ft house the total time of service was about 2 hours.A decomposed rodent was found and removed. First time clients and first cleaning since our home purchase. Dryer vent cleaned also. Would recommend.

I called Guarantee Cleaning services late Friday afternoon after waiting 3 days for a pest control company to respond to a dead rodent under my house. The pest company charged me $99 to tell me it was in my duct. Because of the concern of the office that I would have a dead rodent smelling all weekend, they directed my call right to the owner. Service was arranged for Saturday morning. They were both professional and gracious. I HIGHLY recommend them!
