What is the service capacity of your company?
Service-Tech has the expertise and capabilities to handle cleaning and service projects of all sizes and complexities, as well as to make adjustments per any special requirements pertaining to your specific job site. We typically work directly with the end-user; however, subcontracting is welcome.
How do you determine your costs?
The cost of any given project is subject to a number of variables, such as the amount of dirt and debris to be removed, the condition of the equipment, location, size and degree of difficulty of the work, and if rental equipment is required. For a FREE ESTIMATE, Contact Us.
How do I get a free estimate?
Just call or email us to talk to our estimating/sales staff. From there, we will conduct a site visit, review mechanical drawings, analyze the scope of work (in conjunction with your work environment). For a FREE ESTIMATE, Contact Us.
Is your work guaranteed?
Absolutely, our work is fully guaranteed. We ensure customers are completely satisfied.
Are you insured?
Yes, all of our technicians have Workers’ Compensation and liability insurance.
Are your workers trained on safety protection?
Yes, our technicians are trained on and adhere to OSHA (Occupation Safety and Health Administration) standards and regulations, including: lockout/tagout, respiratory protection, confined spaces, eye and hearing protection. personal protective equipment (PPE), fire prevention, ladder safety and fall protection, heat and cold stress protection, walking and working surfaces, asbestos awareness, aerial lifts, and hazardous communication.
Is it really necessary to clean the entire HVAC system rather than just the ductwork?
Components throughout the system get soiled over time. Dirt and contaminants collect on the fan blades, coils, plenum areas and grilles. Dirt typically originates at the air handler via the return ductwork.
What about the coils?
Clean coils significantly improve air flow and the operating efficiency of the system; thereby reducing energy consumption. Cleaning removes mold, rust, contaminants and microbials all of which contribute to poor indoor air quality (IAQ).

How do I get a quote to clean my Air Conveyance System (ACS)?
In the case of a commercial building, school or hospital, one of our experienced Project Estimators will meet with the building’s Facility Manager to conduct an interview, followed by an inspection of the air handling unit (AHU) and surrounding area to determine accessibility to the ductwork, grilles and diffusers. If mechanical drawings of the ductwork system are available, the estimator will request these in order to verify the amount of ductwork, as well as to determine other components throughout the system, such as VAV’s (Variable Air Volume), Project in front of Estimator (Project Estimator), reheat coils, etc.
What precautions do you take when cleaning HVAC units in a hospital to protect the indoor environment?
All of our vacuum equipment is HEPA (High Efficiency Particulate Air) filtered. These filters go beyond trapping large particulates. They also capture microscopic-sized pollutants like pollen, dust mites, pet dander, mold spores and even tobacco smoke. To ensure indoor environments are protected, we access the ductwork (typically located above the acoustic ceiling) via a mobile dust containment system. This is designed to create negative air pressure that captures and filters dust and contaminants so they are not released into any occupied space in the hospital.
How often do we need to have our HVAC system cleaned?
That depends on a number of factors including: the quality and thoroughness of the previous cleaning, any recent construction, the location of the air intake, air surrounding the building, any pets onsite, and respiratory sensitivities among the building occupants. Feel free to call us at 800-992-9302 to discuss your situation.
Combustible Dust Abatement:
Can dust that collects on overhead structures actually catch fire?
Unfortunately, yes. Over time, dust and debris from different types of manufacturing operations collect on overhead pipes, ductwork, light fixtures, structural steel, ceiling plenums and elsewhere. This accumulation of dust and debris poses a potentially hazardous condition known as combustible dust. Combustible dust is generated from particulates of paint, plastics, chemicals, flour dust, wood, and paper products, etc. In certain conditions, these particulates can cause a fire or explosion. Service-Tech technicians are trained and experienced in using our specialized equipment to safely remove combustible dust.
How do you go about safely removing combustible dust and nuisance dust from overhead structure?
We use vacuum cleaning with grounded & explosion-proof industrial vacuums — the safe and acceptable approach to carry out this potentially hazardous process. Service-Tech technicians undergo rigorous training and have many years’ experience in using our specialized equipment to safely remove combustible dust. Note: When attempts are made to remove dust using unapproved and unsafe methods, such as blowing it down with compressed air, the dust cloud created from this process can be highly explosive.
Sealing Air Ducts:
Why should I bother with having small leaks in ductwork sealed?
Duct sealing improves energy efficiency, air balance and thermal distribution (comfort and ventilation) and prevents potential cross contamination and odors from carrying to other areas of the building. Duct sealing in commercial buildings also serves to ensure compliance with building codes and specification for air distribution effectiveness. Service-Tech is a licensed provider of Aeroseal Duct Diagnostics and Sealing Technology, a computer-controlled patented process to repair leaks extremely effectively and efficiently.
