How 617 HVAC Handles Mold
We want to be clear about how this works, because transparency is how we operate.
617 HVAC technicians are HVAC specialists, not mold testing or remediation specialists. We understand where mold hides in mechanical systems, what conditions create mold risk, and when a situation requires certified testing.
When we identify mold risk during a video inspection or service call, we do not guess, treat it ourselves, or minimize it. We bring in a certified mold testing and remediation partner.
Our partner conducts the testing directly: the indoor unit, drain pan, evaporator coil, and accessible ductwork, using professional equipment with chain of custody documentation. You receive certified third-party results.
Why We Do It This Way
Massachusetts does not require a specific state mold license, but professional mold testing requires industrial hygienist expertise, certified sampling equipment, and proper chain of custody protocols.
These go beyond what an HVAC technician should provide. We know our lane, and we work with the right people when it ends.
Where Mold Hides in HVAC Systems
The drain pan beneath the evaporator coil collects condensation during every cooling cycle. Standing water creates ideal mold conditions within 24 to 48 hours if drainage is impaired.
The evaporator coil operates in a consistently moist environment, making it a common surface for biological growth.
Supply and return ductwork in humid environments, particularly in older Boston and Cambridge homes where vapor barriers may be inadequate, can develop mold on interior duct lining.
Air handler cabinets in basement and utility room installations accumulate dust and moisture that support growth.
None of these are visible during a standard service call. They require video proof inspection.
The Real Story
We see the same thing across hotels, job sites, commercial properties, and homes throughout Greater Boston: ductwork that has never been inspected, systems running for years without anyone looking inside, and equipment that looks maintained from the outside while the inside tells a different story.
Most people are never told this is happening. No one looks. The system runs, the air circulates, and the exposure continues.
The difference between a system with a mold problem and a system without one usually is not the equipment. It is whether anyone ever looked.
Mold Testing and Your Maintenance Plan
Mold inspection is built into every 617 HVAC maintenance visit. On every service call, our technicians inspect the drain pan, coil, and accessible ductwork for signs of biological growth.
If anything raises concern, we initiate testing with our certified partner before the problem grows.
Professional mold testing with certified third-party sampling and results review is included in our Optimal maintenance plan at $150/month. It is also available as a standalone service.
