MN Duct Pros Access, Asbestos, and Mold Limitations

Access and Service Limitations: We try to be upfront about any possible issues/limitations.

Remodeling/Construction projects: We recommend waiting until all remodeling projects are completed before having your air ducts cleaned. A surprising amount of dust and debris often makes its way back into the system regardless of containment efforts. Even in brand new construction we often find a large amount of drywall dust contamination. 

Suspect Asbestos/mold: Asbestos and mold can be extremely dangerous for the homeowner, occupants, and our team. We have found suspect asbestos and/or mold in roughly 50% of homes built before 1980. If we find signs of either, we will immediately bring to your attention to discuss remediation. We will not clean systems with suspect mold or asbestos present because of the dangers it may pose to our customers and team members. Please let us know if you have any concerns ahead of time.

Spatial Limitations: 
1. Furnace Access- We need to cut two 8 inch holes in the system for our negative air machine. One on the supply side above the A Coil and another on the return side before the furnace filter. We tape, screw, and patch these holes with the proper grade galvanized steel. 
2. Vent Access- We will need access to all of your supply and return vents. We will need to remove most vents from floors or walls. If the vents are painted on or obstructed we will notify you. The options from here vary, but we are almost always able to clean every vent. We will discuss the options, including cutting around the vent with a razor blade to remove or using a specialized micro-line, a single whip tool, designed for these limited applications.
3. Equipment Mobility- We need a clear path to the furnace for our negative air machine (roughly 2.5 ft x 2.5 ft x 4 ft tall) and some working space around the furnace area.
4. Parking- We need to park within 100 ft of an entrance to the home or building.

5. Duct or Trunk Access Limitations: Occasionally, we run into trunk lines where access is limited. Most often these are in the form of hop over trunks, where they use floor joists to hop up and over to a separate trunk line. These can be very difficult to access in some homes, but we will explain the limitation as well as options for remediation.
