Monster Vac
We are a heating and air conditioning contractor that specializes in cleaning air ducts, air handlers, furnaces, air conditioners and coils in homes, commercial buildings, schools, health care facilities and more. People want to know that when a contractor performs work for them, they will stand behind their work.

Monster Vac excels at that. We give 100% attention to any complaints or questions that arise from our service. When people watch us work they are amazed at the work and care we put in to cleaning your heating and AC ducts. Check out some of the testimonials from both our residential and corporate clients.
Services
We are often asked why homes and commercial buildings need air duct cleaning and system cleaning. The answer to this question is that air ducts, blower fans and coils continually have dust, lint, dirt, bacteria and allergens pass over and through them. And, as these contaminates accumulate, indoor dust becomes more prevalent, heating and cooling systems don't operate efficiently, and in some cases, they can have an adverse effect on your health.
Monster Vac is the pioneer in residential home air duct cleaning services and HVAC system cleaning, and we are still the innovative leader today. We service more homes than any other air duct cleaner in Colorado. Why? Because we do the most thorough job, have the best technicians and we respect your home.
Colorado homes are stunning. They're surrounded by pine trees, aspens, and beautiful wild grasses. But over time, that beauty can build up in the form of air pollutants, allergens, and pollen residue. Chances are, you're already very familiar with this fact, and your seasonal allergies have not been too happy about it.
If you're like most homeowners in Colorado, then you've probably never even heard of an evaporator coil. But a dirty evaporator coil can actually cause a world of problems if it goes unnoticed for too long. Evaporator coils play a huge role in your home's air flow and air quality. But they're also prone to gunk - especially out here in Colorado.
You're not alone. In fact, most homeowners have no idea what their home's condenser coil is or even where it's located. Even so, your condenser coil plays a pivotal role in your home's air quality and comfort. You'll need to get your condenser coil cleaned once a year if you want to ensure that your air conditioner is circulating cool, comfortable, healthy air consistently.

Great Service! Our family was affected by the fire in Louisville and we reached out to Monster Vac after many recommendations from Facebook. I wanted to say that Tyler Bunch and Jose Martinez are a great asset to your team! Amazing customer service. Worth the money!

Matt and Bryan were phenomenal. They showed up on time, took time to assess the best approach to my cleaning (my home is 106 years old). They were thorough and went through their work with me at the end. I highly recommend this company for any of your HVAC needs!

Tim and Kendrick were fantastic. There got the job done while answering all our questions. This house was built in 1971. To our knowledge the vents have never been cleaned. How wonderful to turn on the heat and it works.
Thanks again to Tim and Kendrick.

Bryan did a great job! He was on time and he took the time to explain the process of what he would be doing. He answered all of my questions. He showed me his work and explained what he had done. He cleaned up the area after he completed the job. I was impressed with his work ethic! Jim did a great job rescheduling me when the original date had to be cancelled due to illness by one of the workers. I really appreciated his efforts. I highly recommend Monster Vac to anyone considering duct cleaning in their home.

Excellent service. My husband and I were affected by the fire in Superior and we reached out to Monster Vac after a recommendation from my brother in law who works in insurance. From beginning to end I felt like I was in good hands! First I wanted to say that Steve is an absolute gem. He has one of the best radio voices I’ve ever heard. He is kind and responsive and made my husband and I feel at ease through the entire process. Thank you, Steve! Then Monster Vac sent out Bryan and Travis who were extremely polite, very thorough and gave us EXCELLENT customer service. Monster Vac couldn’t possibly

Monster Vac was able to schedule my duct cleaning within a reasonable period of time. Justin showed up on time, explained the pricing and got right to work. In a few hours those ducts were clean. Justin cleaned up around the house and everything looked great. We were very happy with the overall experience.

A wonderful experience and well worth the investment for my home. Everything was professional.
The initial online intake process followed up with Monster Vac immediately call. The scheduler Steve took the time to understand my home's duct work. The cleaning crew spent 3 hours working on ever little detail, plus they left the house cleaner then how they found it.
I don't write reviews often, but this service warrants my time.

Justin and Bryan R. arrived on time and worked with us to get set up in a place that would minimize inconvenience to our neighbors. Not only did they perform thoroughly and professionally, they even cleaned up afterward! Thank you for helping us starting off clean and comfortable in our new home, Monster Vac!

Our initial contact with MonsterVac was with Steve via the phone. He was vey helpful, considerate, and professional. The 2 techs who came and performed the duct cleaning were Tim and David. Much like Steve they were very considerate, plus were on time and were highly competent. I was greatly impressed by the quality of these 3 MonsterVac staffers. All of which was reflected in the outstanding job they did in my home. I highly recommend them for anyone who wants the job done right, by the right company/people

Bravo to Monster Vac!! I have never quite experienced anything quite as wonderful as my latest visit with Monster Vac. We had work done at our home and we found things in the vents that were back to the original construction. The team was very accurate and technical. We worked specifically with Tim and Jared and they were very knowledgeable and super friendly. We had a ester UV filter installation question and we called back and they sent their top tech/manager, little did I know it was the owner. Brandon, the owner came out and helped me so much. Monster Vac is an amazing company

Just finished my duct cleaning. Noe was a very polite technician and cleaned up everything as needed and did a nice job. He showed me the dust in the vents and then how clean they were afterwards. Hopefully, I will not have to do this again for many, many years! Thanks. The office staff (Jim) was also very helpful in scheduling my appointment. Noe arriv ed right on time and was done in about 3 hours.

Our AC and furnace were both weak and when we had Monster Vac clean the vents we saw why. A huge plug of fur, dust, and crud had formed in our AC coils and blocked 95% of the air flow. Also, our ducts had much debris and dust in them. The cleaning was thorough and Jason S was very professional. Since the cleaning our heat has barely been on and the house is very comfy. I can't wait to see our next Xcel energy bill. I am sure it will show a significant savings. Thank you Monster Vac!

These guys were 3 times as expensive as anyone and could not give me a reason why. Shop this service and use a company that can explain why their cost is 3x more than anyone else. Plus, they gave me a quote without even seeing my house and just assumed how many vents I have. My other quotes were with companies that cared enough to come to the house and actually see what needed to be done

Expensive! I called for a quote for a dryer vent cleaning, and I was quoted $225 by Monster Vac. I called two other companies for quotes - both of whom have great yelp reviews, and their quotes were $92 and $69 for the exact same thing.

Needless to say, I didn't end up using Monster Vac, but I'm sure they would have done a good job. Just no need to overpay for a service.

Josh from Monster Vac arrived on time, was very pleasant and professional. He was even helpful in reminding us to watch the cats! It took about 3 hours and you could hear the chunks of plaster going through the hoses. The house is 69 years old and the ducts had never been cleaned! He didn't show us the photos, but told us that it was pretty bad. Looking forward to winter to check it out!!
Well done! The estimate for 10 vents was $525 and that is what it cost. Worth it for the professional quality of the work.
