Diamond Duct Cleaning Inc

Diya phoned the night before the scheduled appointment to confirm we were still on. He turned up on time. His work was very professional keeping me appraised of what he found and how he would address the completion of what was necessary.
His price was very competitive for the services he provided.
I would have no hesitation in recommending him to family and friends.

Diamond Duct Cleaning provides excellent service at a reasonable price. Diya works very professionally and does the extras that other companies simple won't do. I have already recommended Diamond Duct Cleaning to my neighbour, and won't hesitate to recommend to others in the future.

Diya called the day before to confirm the appt. He and his helper showed up exactly on time and were very friendly. Diya carefully explained every step and provided some cleaning tips and tricks for the future to improve air flow. Diya took before and after pics to show me just how dirty the furnace and A/C coil was. He was very professional and thorough. The price was well within the range I would expect to pay for this service. I was completely satisfied and would fully recommend him to anyone living in Durham or the GTA.

Diya cleaned my ducts in June 2014. My house is about 10 yrs old and I've had my ducts cleaned before! I couldn't believe all the stones and debris which he was able to collect from when the house was built! He wasn't satisfied until he felt everything was out. Amazing service & he takes pride in his work! My sister has already used Diya upon my referral and I will continue to spread the news. I wish him years of success...see you on your next visit!

Not only are the workers courteous and polite from the time they enter the property. They make sure to show you the difference in their services by taking the time to explain and show the difference between a job well done as compared to a sloppy job. We are more educated about our air system as well as it is working better than ever. If you want your system cleaned properly I strongly suggest getting the best in the business and that would be Diamond Duct Cleaning, HANDS DOWN!!!!!

I have done duct cleaning before - or, I thought I did. These gentlemen from Diamond Duct Cleaning came in and literally cleaned the vents with real passion and respect and all from top to bottom. The things that they found in my duct work was unbelievable. Regardless, whatever was there is now completely gone! Many thanks for the good, honest work and I will be making sure I pass this info along to others looking for their ducts cleaned. I am very satisfied! Thanks again.. Sam.

We bought this on an email deal. Over the years we have tried several companies and Diamond Duct Cleaning is by far the best we have had. Diya and his partner were very professional and thorough. They performed the work with care and respect for our belongings. They explained each step and went over all findings with us. We would definitely use them again in the future and would recommend them to anyone needed duct cleaning done.

Diamond Duct Cleaning company help me to clean my vents and they do their work very well. After their cleaning, I feel my home's air is fresher than before. Thanks very much for Diya and his partner.

After looking for a while for duct cleaning services, I came across Diamond Duct Cleaning and decided to give them a call. I was impressed with Diya on the phone itself as he was very courteous and straightforward. He assured me that he will check everything and then recommend what I need to do and need not do. Last year, I was told to replace my A/C when some company came to clean my A/C and furnace as selling and installing these was their real business. Diya saw the A/C and said it was fine and will be for a few years, the furnace was dirty like it had never been cleaned, so not sure what I paid for last year. Diya cleaned everything he told me he would and answered all of my questions (I had many). I would highly recommend Diamond Duct Cleaning because of their work ethic and professionalism. What I valued most though was that Diya and his associate were very polite, patient and most importantly honest. We can feel the difference in air quality in our home, it feels lighter and cleaner.
Thank you so much Diya and see you in 2 years.

I definitely recommend this company.
They came to my place on time, very polite, knowledgeable, cleaned after their own, very accurate and precise and they gave me what ever I expected to receive from an excellent customer service.
