Project: Duct and Vent Cleaning

Mor did a great job. He was professional from the first contact to completion of the job. I expanded the scope of the job from the original quote and Mor demonstrated flexibility and a willingness to accommodate my schedule. I have no doubt that the dryer vent cleaning saved me thousands of dollars in preventing fire from the impacted lint. I will consider future service from 1st Global Cleaning. Nice job! See my furnace filter after the initial cleaning!? Gross!

This customer rated you highly for work quality, responsiveness, punctuality, professionalism, and value.

What great service! Mor came by to give me a quote the day I called. I booked the service the next day after getting quotes from two other local companies that did not provide as many services and were sometimes twice the price. Mor cleaned all the vents, the return, the main line, and the dryer vent for one flat fee. He was able to make time to fit my schedule, which was so appreciated. He did a wonderful job and was very thorough. The before and after pictures were astonishing and I could tell a major difference in my air quality in about 30 minutes. The dryer vent was awful; I watched Mor pull a bird’a nest out of it – major fire hazard. Overall, incredibly pleased with the service. I plan on continuing to use this service and would definitely recommend Mor to anyone looking for fast, friendly, and thorough service. Thank you, Mor!

Mor came out the same day he called to follow up and quoted us a very fair price. He then asked if we would like the work done while he was there and we agreed. He then fully described how his cleaning system worked and demonstrated, with photos, the before and after condition of our vents. He is very knowledgeable, extremely efficient and a pleasure to do business with.

Very efficient, and did an excellent job cleaning out the filthy ductwork in my new house – Mor was very friendly and took exceptional care to thoroughly clean everything and keep me informed as he was going through the house. Well worth the cost and I am very relieved to have all that dust, hair and other nasty debris gone! Would highly recommend!

Project: Clean Heating & Cooling Air Ducts & Vents

We purchased a living social deal and only intended to have a few vents cleaned. Mor did a thorough inspection and showed us pictures of how truly disgusting our vents were. He offered us a fair quote without any pressure to upsell us on additional services. We chose to have him do the full service to our house, 3.5 hours later we are breathing easy. Mor was friendly, professional, informational, and diligent. Highly recommended!!

Frequently Asked Questions

Why 1st Global Cleaning?

1st Global is a family owned and operated business.  We provide high quality customer service and guaranteed results.  Our customer reviews speak for volumes about the time and attention to detail that we take with each air duct cleaning and vent cleaning job.

What is air duct cleaning?

Professional air duct cleaning is used to remove any build up within your ductwork. Over time, these pathways can collect dust, carcinogens, and even mold! Don’t let these issues go undetected. Book a professional duct cleaning service today to be sure you and your family are breathing quality indoor air. Did you know that the average person spends 90% of his or her life indoors? Improve the quality of the air inside your St. Louis, MO area home with 1st Global Cleaning and their air duct cleaning service. During our thorough cleanings, all ductwork passageways will be inspected and sanitized. To clean the supply, intake, and return ducts throughout your home, we use specialized blowers, vacuums, and brushes.

How often should your air ducts be cleaned?

Typically we suggest a home’s air ducts be cleaned every five to eight years. Homeowners with children, pets, respiratory issues, or a compromised immune system may want to get their HVAC duct system cleaned more often. The better filtration the system has cut down on cleaning frequency.

Will the duct cleaning process leave a mess in my home or commercial property?

No. Our technicians use the highest quality and most state of the art duct cleaning equipment. All vacuum devices used in our process utilize HEPA (high-efficiency particulate air). This filtration is rated at 99.97% at.3 microns– meaning there will be no mess left behind once the duct cleaning job is complete!

Why is my ductwork sweating?

The water you see dripping from your ducts is most likely from condensation and is not something to look past. If left untreated, this water build up may lead to leaky ceilings or mold growth. How did this condensation get here? It likely formed when warm, humid air came into contact with the much colder surface of your home’s ductwork. Once you notice this sweating, it is important for you to call in a team of professional air duct cleaners right away to fix your HVAC issue before your drywall begins to rot and mold starts to grow.
Is duct cleaning worth it?

Will a duct cleaning reduce my energy bills?

Research by the U.S. Environmental Protection Agency has confirmed that HVAC system cleaning may allow systems to run more efficiently. Why is this the case? Air duct cleaning effectively removes debris from sensitive mechanical components. By investing in a professional air duct cleaning, your system may be less likely to break down and use less energy to produce the same results. Get the most out of your ductwork and cut back on your energy usage by scheduling ductwork cleaning service every three to five years.

Is air duct cleaning necessary?

If you want to breathe clean, filtered air, then yes, there is a need to have your ducts professionally cleaned every five to eight years. Ductwork cleaning removes any contaminants from these pipes including dust, pollen, bacteria, and mold. Without quality duct cleaning service, you and your family are at a higher risk of breathing polluted air. Keep your family and your co-workers healthy by remembering to schedule regular duct cleaning service with the team of professionals at 1st Global Cleaning.

How are dryer vents cleaned?

Both residential and commercial dryer vents are cleaned with a brush and a vacuum system that goes through the entire length of the vent. This snaking procedure ensures that all the lint is removed from the vent walls– reducing any build up!
How long does a dryer vent cleaning take?

For a residential property, a dryer vent cleaning will take about one hour. However, a commercial property could take longer depending on the size and amount of dryer vents that need to be cleaned.
