This is the 2nd time in 7 years we have had our ducts cleaned. The first time was another company and they did not do nearly as thorough of a job. Monster Vac used cameras and showed us before and after pics. They did an excellent job - we will use them again in the future. It was worth the additional cost to have it done right. Very happy with their service.

This is the third time I have used Monster Vac. They continue to do a great job. I would highly recommend them and will continue to use them whenever the need arises.

Monster Vac arrived on time. Bryan and James were friendly and professional. They spent several hours cleaning our ducts which had not been cleaned for at least 10 years (when we moved in) and probably longer. There was so much accumulated dust, dirt, etc. We were shown before and after pictures of the ductwork. Would definitely recommend.

Excellent work by MonsterVac. They come with some HEAVY duty equipment and leave no stone unturned.Justin and Bryan did an excellent job.Explained every detail to me, and were very friendly. I am extremely happy with their work. They did a few things extra without being asked, like replacing dried out duct tape and filling in holes in exposed duct work with a filler.I caution those that are entertaining a less expensive company, you get what you pay for. MonsterVac is the best at what they do.

Justin and David came to clean our 2 furnaces and over 30 vents last week - a big job (over 30 years since we had the ducts cleaned). They were competent, curteous, and diligent. They explained the technical process and went to work. Finished in the prescribed time and and we are pleased with the results.SOMEHOW, our water heater, which was next to the 2 furnaces in the basement was not working after they left. I found the pilot light was not on and I could not get it relit after multiple tries to start it. I called Jim at the Monster Vac office and he quickly sent out Louli (sp?) who was able to start it. It was 3pm when I called and my wife was not in a good mood with just cold water in the house on a Friday night with the weekend approaching. Louli arrived at 3:30pm and somehow started it. A GREATTESTAMENT TO THEIR CUSTOMER SERVICE AND CARING ATTITUDE.(not really sure Monster Vac caused the problem but they came to the rescue - the thought perhaps was that all the strong air from the vacuum cleaning the furnaces could have blown out the pilot light ???)
